* Mark xAI models retiring on 2026-05-15 (#28788)

Per https://docs.x.ai/developers/migration/may-15-retirement, xAI is
retiring the following slugs on 2026-05-15 (auto-redirect to grok-4.3
with various reasoning efforts; callers continuing to use the old slugs
will be billed at grok-4.3 pricing):

  grok-4-1-fast-reasoning{,-latest}      -> grok-4.3 (low effort)
  grok-4-1-fast-non-reasoning{,-latest}  -> grok-4.3 (none)
  grok-4-fast-reasoning                  -> grok-4.3 (low effort)
  grok-4-fast-non-reasoning              -> grok-4.3 (none)
  grok-4-0709                            -> grok-4.3 (low effort)
  grok-code-fast-1{,-0825}               -> grok-build-0.1
  grok-3                                 -> grok-4.3 (none)

Only the direct xai/ slugs are tagged; third-party hosts (azure_ai,
oci, vercel_ai_gateway, perplexity/xai) run their own schedules. The
grok-3 retirement list explicitly names only the base grok-3 slug — the
-mini / -fast / -beta / -latest variants are not listed, so they remain
untouched.

* feat(moonshot): advertise json_schema response support on live models (#29683)

litellm.responses() already routes Moonshot through the responses->chat-completions
bridge, and Moonshot honors response_format json_schema on chat completions. The
cost-map entries left supports_response_schema unset, so discovery layers that gate
on that flag dropped Moonshot from structured-output / responses listings even though
the capability works end to end.

Set supports_response_schema on the nine models currently live on api.moonshot.ai:
kimi-k2.5, kimi-k2.6, the moonshot-v1 8k/32k/128k text and vision-preview variants,
and moonshot-v1-auto. Verified against the live API that each honors json_schema and
that litellm.responses() returns schema-valid structured output through the bridge.

* chore(moonshot): mark models retired from api.moonshot.ai as deprecated (#29685)

Thirteen Moonshot/Kimi models in the cost map no longer resolve on
api.moonshot.ai (all return 404). Stamp each with its deprecation_date from
platform.kimi.ai/docs/models rather than deleting the entries, so historical
cost calculation keeps resolving the names while tooling can surface the
retirement.

Dates: kimi-thinking-preview 2025-11-11; kimi-latest and its 8k/32k/128k context
variants 2026-01-28; the kimi-k2 preview/turbo/thinking series 2026-05-25; the
moonshot-v1 -0430 snapshots use their own 2024-04-30 snapshot date (Moonshot
publishes no discontinuation date for them).

* fix(moonshot): drop temperature for reasoning models (kimi-k2.5/k2.6) (#29687)

Kimi reasoning models reject every temperature except 1; a request with
temperature=0.2 returns "invalid temperature: only 1 is allowed for this model".
litellm only clamped temperature into [0.3, 1], so any value below 1 still 400'd.

Drop the temperature param entirely for reasoning models (gated on
supports_reasoning, the same signal transform_request already uses) so the model
default is used; the non-reasoning moonshot-v1 models keep the existing clamp.

* Forward custom_llm_provider through the Responses API bridge (Fixes #28505) (#28575)

* Forward custom_llm_provider through the Responses API bridge (Fixes #28505)

When a Chat Completions request to a GPT-5.4+ model contains both
`tools` and `reasoning_effort`, `completion()` auto-routes through
`responses_api_bridge`. The bridge handler called
`litellm.responses()` / `litellm.aresponses()` without forwarding the
already-resolved `custom_llm_provider`, so the downstream call
re-invoked `get_llm_provider()` with `custom_llm_provider=None` and
stripped a second provider prefix from a `provider/provider/model`
deployment string.

For a deployment configured as `openai/openai/openai/gpt-5.5`,
the bridge flow sent `openai/gpt-5.5` to the upstream API instead of
the correct `openai/openai/gpt-5.5`. Upstream APIs that enforce
model-name allow-lists rejected this as `key_model_access_denied`.

Fix: pass the locally-resolved `custom_llm_provider` into both the
sync `responses()` and async `aresponses()` calls so the downstream
`_resolve_model_provider_for_responses` sees an explicit provider
and skips the second prefix-strip.

New regression test
`tests/test_litellm/completion_extras/test_responses_bridge_provider_propagation.py`
pins both call sites: each must forward `custom_llm_provider`.

* fix(28505): set custom_llm_provider on request_data instead of as duplicate kwarg

Greptile flagged that the previous patch passed custom_llm_provider as an
explicit kwarg to responses()/aresponses() while request_data already
carried it via the spread of sanitized_litellm_params, which would raise
TypeError: got multiple values for keyword argument on every real bridge
call.

Switches to assigning request_data['custom_llm_provider'] before the call
so the resolved provider wins over whatever sanitized_litellm_params spread
in, without duplicating the kwarg.

Updates the regression test to seed request_data with a sentinel
custom_llm_provider so it actually exercises the overwrite path (the
previous test mocked transform_request with a minimal dict and never hit
the conflict).

* chore: trigger shin-agent re-eval on retargeted staging base

* chore: trigger shin-agent re-eval against updated Greptile state

* Add jp. Bedrock cross-region inference profile for claude-opus-4-7

AWS Bedrock documents jp.anthropic.claude-opus-4-7 alongside the
existing us./eu./au./global. profiles for Claude Opus 4.7
(ap-northeast-1 Tokyo / ap-northeast-3 Osaka), but the entry is
missing from model_prices_and_context_window.json. Tokyo-region
users currently get an "unknown model" error when routing through
the JP geo profile.

Adds the entry to both the canonical file and the bundled backup,
mirroring the recent pattern for sonnet-4-6 (#27831). Pricing matches
the other regional profiles (10% premium over base/global).

Regression test pins all six documented profiles (base, global, us, eu,
au, jp) and asserts pricing parity between jp. and au. variants.

* feat(soniox): add soniox audio transcription integration (#29508)

* feat(openmeter): add OPENMETER_TRUST_REQUEST_USER to prevent forged attribution (#29650)

The OpenMeter callback resolves the CloudEvent subject from kwargs["user"]
first, then falls back to the key-bound user_api_key_user_id. For
multi-tenant proxy deployments, a client can set `"user": "..."` in the
request body and cause their usage to be attributed to that arbitrary
string — a billing-attribution forgery risk.

Adds OPENMETER_TRUST_REQUEST_USER env var (default "true" for backward
compatibility). When set to "false", the request-supplied `user` field is
ignored and the subject is resolved solely from user_api_key_user_id.

Matches the existing env-var-driven config pattern in this file
(OPENMETER_API_KEY, OPENMETER_API_ENDPOINT, OPENMETER_EVENT_TYPE).

* feat(search): add you_com as a search provider (#28370)

* feat(search): add you_com as a search provider

Registers You.com Search API as a first-class `search_provider` in the
`search_tools` registry, alongside Tavily, Exa, Perplexity, etc.

- New adapter: litellm/llms/you_com/search/transformation.py
  - POSTs to https://ydc-index.io/v1/search
  - Auth: X-API-Key from YOUCOM_API_KEY (or explicit api_key)
  - Maps Perplexity unified spec: max_results -> count,
    search_domain_filter -> include_domains, country -> country
  - Flattens results.web + results.news into a single SearchResult list;
    snippet prefers snippets[0], falls back to description; page_age -> date
- Registry: SearchProviders.YOU_COM in litellm/types/utils.py and wired
  into ProviderConfigManager.get_provider_search_config()
- Pricing entry: model_prices_and_context_window.json (placeholder $0.0;
  happy to adjust to maintainers' preferred public number)
- Docs: example router config snippet and example proxy yaml updated
- Tests: tests/search_tests/test_you_com_search.py - 5 mocked tests
  (payload shape, domain filter mapping, snippet fallback, news flattening,
  missing-api-key error)

Refs upstream expansion signal: #15942

* review fixups: normalize api_base, lowercase country, scope env-var to test

Addresses Greptile inline review comments on #28370:

- get_complete_url: strip trailing slashes from api_base *before* the
  endswith("/v1/search") check, so a custom base like ".../v1/search/"
  doesn't become ".../v1/search/v1/search".
- transform_search_request: .lower() country before sending, matching
  Tavily's convention so callers using the unified spec form ("US") get
  consistent behavior across providers.
- Tests: replace direct os.environ writes with an autouse monkeypatch
  fixture so YOUCOM_API_KEY is set per-test and removed afterwards.
  The missing-key test now uses monkeypatch.delenv. New test asserts the
  trailing-slash normalization above.

Reverts the ARCHITECTURE.md / example yaml edits per the reviewer note
that documentation changes belong in the litellm-docs repo.

* support keyless free tier (api.you.com/v1/agents/search) as default

You.com offers an IP-throttled keyless endpoint that returns the same
response shape as the keyed one (~100 queries/day, no signup). This is a
significant onboarding lever - mirrors the keyless DuckDuckGo/SearXNG
providers already in the search_tools registry.

Behavior:
- YOUCOM_API_KEY set        -> keyed:  POST https://ydc-index.io/v1/search
                                       (X-API-Key header)
- no key                    -> free:   POST https://api.you.com/v1/agents/search
                                       (no auth)
- YOUCOM_API_BASE override  -> honored as-is

Tests:
- New: test_you_com_search_keyless_free_tier - asserts URL + absence of
  X-API-Key when no key is configured.
- New: test_you_com_search_validate_environment_keyless - asserts the
  config no longer raises when the key is absent.
- Removed: test_you_com_search_raises_without_api_key (the precondition
  no longer holds).
- Existing payload/domain-filter/etc tests still cover keyed mode via
  the autouse YOUCOM_API_KEY fixture.

Verified both endpoints accept POST + return identical JSON shape:
  results.web[] / results.news[] with title, url, snippets, description,
  page_age.

* register you_com in provider_endpoints_support.json

Adding `litellm/llms/you_com/` requires a corresponding entry in
provider_endpoints_support.json or the
code-quality/check_provider_folders_documented CI check fails.

Follows the compact tavily/serper pattern - endpoints: { search: true }.
Local run of the check now reports "All 114 provider folders are documented".

* move tests under tests/test_litellm/llms/ so CI exercises them

The litellm CI workflows scope unit tests to `tests/test_litellm/...`
(see test-unit-llm-providers.yml: `tests/test_litellm/llms` path), so
tests living under `tests/search_tests/` are never run in CI - which is
why codecov reports 0% patch coverage for the new adapter even though
the unit tests exist and pass locally.

Move test_you_com_search.py into `tests/test_litellm/llms/you_com/` so
the test-unit-llm-providers job picks it up. 7/7 tests still pass at
the new location.

(Sibling search-only providers - tavily, exa_ai, brave, etc. - still
live only in `tests/search_tests/` and would benefit from the same
move, but that is out of scope for this PR.)

* fix(you_com): pin Accept-Encoding: identity to dodge keyless gzip bug

The keyless free-tier endpoint (api.you.com/v1/agents/search) advertises
Content-Encoding: gzip but returns a body that httpx's decoder rejects
with `zlib.error: Error -3 while decompressing data: incorrect header
check`, surfacing as litellm.APIConnectionError in user code. curl works
because it doesn't request compression by default.

Pin Accept-Encoding: identity in validate_environment so the upstream
server skips compression entirely. Harmless on the keyed endpoint
(ydc-index.io/v1/search) which negotiates content-encoding correctly.

The header uses setdefault so a caller-supplied Accept-Encoding still
takes precedence. (Server-side bug has been flagged to the You.com team
separately - once fixed there, this workaround can be removed.)

New unit test: test_you_com_search_pins_identity_accept_encoding.

Add MiniMax's new flagship MiniMax-M3 to the native minimax provider:
512K context, 128K max output, native multimodal (supports_vision),
reasoning, prompt caching. Pricing (USD/M tokens): input 0.6 / output
2.4 / cache read 0.12. M3 has no active prompt-cache-write tier, so
cache_creation_input_token_cost is omitted.

Updated both the root model_prices_and_context_window.json (remote

* fix: address greptile and veria review feedback

- langfuse: guard httpx_client injection behind version check (>= 2.7.3)
- soniox: propagate audio_transcription_duration in _hidden_params for spend tracking
- soniox: give SONIOX_API_BASE env var priority over caller-supplied api_base
- mcp: replace CancelledError catch with asyncio.wait_for + TimeoutError

* chore(mcp): add migration for per-server timeout column

* fix(test): add tool_use_system_prompt_tokens to model prices schema validator

* fix: mcp timeout test uses real asyncio.wait_for timeout; you_com get_complete_url respects resolved api_key

* fix: forward resolved api_key into you_com endpoint selection and apply timeout to soniox polling GETs

The search flow resolves api_key in validate_environment but never passed it
into get_complete_url, so a programmatic api_key (with no YOUCOM_API_KEY in the
env) set the X-API-Key header yet still selected the keyless free-tier endpoint.
Forward api_key through both the search entrypoint and the http handler so the
keyed endpoint is chosen.

HTTPHandler.get/AsyncHTTPHandler.get had no timeout parameter, so the Soniox
poll and transcript-fetch GETs silently used the client global default instead
of the caller timeout. Add a per-request timeout to get() and forward the
configured timeout from the Soniox handler.

* fix(soniox): price stt-async-v4 per second so transcriptions are billed

The handler stores audio_transcription_duration in _hidden_params, but the
model carried only token cost fields and the response has no token usage, so
the transcription cost path fell through to cost_per_second and returned $0.
An authenticated caller could transcribe Soniox audio without decrementing
their budget. Switch the entry to output_cost_per_second at Soniox's published
$0.10/hour async rate so the stored duration produces a real charge.

* fix(langfuse): use a dedicated httpx client for the SDK injection

The httpx_client handed to the Langfuse SDK came from _get_httpx_client(),
which returns LiteLLM's globally cached HTTPHandler. If Langfuse closed that
client on teardown it would invalidate the shared client used by every other
LiteLLM HTTP call. Build a dedicated httpx.Client instead, still resolving SSL
verification and client certificate from LiteLLM's configuration.

* fix(soniox): prefer caller-supplied api_base over SONIOX_API_BASE env var

* fix(cohere): support max_completion_tokens on cohere v2 chat (default route) (#29779)

* fix(cohere): support max_completion_tokens on cohere v2 chat

The default cohere_chat route resolves to CohereV2ChatConfig, which did not
list or map max_completion_tokens, so get_optional_params raised
UnsupportedParamsError for the standard OpenAI parameter (the modern
replacement for the deprecated max_tokens). The v1 config already maps it to
cohere's max_tokens; mirror that in v2 and add v2 regression tests.

* fix(cohere): make max_completion_tokens take precedence over max_tokens on v2

When both max_tokens and max_completion_tokens are supplied, prefer
max_completion_tokens explicitly rather than relying on dict iteration order,
and cover both orderings with a regression test.

* fix(azure): apply api_version fallback chain to image edit URL

`AzureImageEditConfig.get_complete_url` only read `api_version` from
`litellm_params`. When callers configured it via `litellm.api_version`
or `AZURE_API_VERSION`, the constructed URL had no `?api-version=` and
Azure responded `404 Resource not found`.

Apply the same fallback chain the Azure chat path already uses in
`common_utils.py`:

    litellm_params > litellm.api_version > AZURE_API_VERSION env >
    litellm.AZURE_DEFAULT_API_VERSION

Adds 5 unit tests pinning each layer of the chain plus a regression
guard for `api_base` that already carries `?api-version=`.

* feat(mcp): core sampling and elicitation flow with security hardening

- Add sampling_handler.py: full MCP sampling/createMessage flow with
  model selection (hint-based + priority-based), auth enforcement,
  budget checks, route restriction gates, and tag policy pre-auth
- Add elicitation_handler.py: MCP elicitation/create relay with
  downstream client capability detection
- Wire sampling/elicitation callbacks in mcp_server_manager.py
  gated behind allow_sampling/allow_elicitation config flags
- Add allow_sampling/allow_elicitation fields to MCPServer type
- Fix session lock deadlock: skip lock for JSON-RPC response POSTs
  (elicitation/sampling replies) with truncated-body heuristic
- Extend client.py with sampling_callback and elicitation_callback
- Security: RouteChecks gate, tag-budget bypass fix, x-forwarded-for
  spoofing fix, Latin-1 header encoding guard
- Add 4 new test modules (model access, priority selection, request
  builder, tool conversion) + update existing MCP tests

* fix(security): run pre-call guardrails before MCP sampling acompletion

Without this, an upstream MCP server with allow_sampling enabled could
send prompts that bypass every guardrail (content filtering, PII
redaction, prompt-injection detection) configured on /chat/completions.

- Call proxy_logging_obj.pre_call_hook(call_type='acompletion') before
  llm_router.acompletion so guardrails fire for sampling sub-calls
- Add HTTPException to the re-raise list so guardrail rejections
  propagate correctly instead of being swallowed as generic errors

* refactor(bedrock_mantle): exclude gpt-oss instead of allow-listing gpt-5 for Responses routing

Frontier OpenAI models on Bedrock Mantle are Responses-only on /openai/v1/responses;
gpt-oss is the legacy family that also speaks chat-completions. Gate by excluding
gpt-oss (which keeps its chat-completions emulation) and defaulting everything else
to the native Responses config, so future frontier models (gpt-6, etc.) route
correctly without a code change. Verified against the live us-east-2 Mantle endpoint:
gpt-oss 400s on /openai/v1/responses while gpt-5.5 400s on both standard paths.

* test(bedrock_mantle): cover supports_native_websocket opt-out

Closes the one uncovered line flagged by codecov on the Responses config.
The assertion documents that Mantle Responses has no realtime/websocket
transport, so realtime routing must not attempt a socket it cannot serve.

* fix(bedrock_mantle): route file_search through emulation instead of forwarding to Mantle

BedrockMantleResponsesAPIConfig inherited supports_native_file_search()
-> True from OpenAIResponsesAPIConfig but never overrode it. Mantle has no
OpenAI vector stores, so a forwarded file_search tool is rejected with a
400 (verified upstream: Tool type 'file_search' is not supported). Opting
out, like the existing supports_native_websocket override, routes the tool
through LiteLLM's file_search emulation instead.

* fix(bedrock_mantle): only route openai.gpt frontier models to Responses

The previous gate excluded gpt-oss and routed every other model to the
native Responses config. But on Mantle only the OpenAI gpt frontier models
(gpt-5.x) are served on /openai/v1/responses; gpt-oss and the non-OpenAI
families (nvidia, mistral, google, zai, ...) are chat-completions only and
400 on that path. Allow-list the openai.gpt- family (excluding gpt-oss)
instead, so chat-only models fall through to the chat-completions emulation.
Verified against the live us-east-2 endpoint: nvidia.nemotron-nano-9b-v2
returns 400 on /openai/v1/responses and 200 on /v1/chat/completions.

The /cache/ping endpoint included a full Python traceback in its 503 error
response body (inside the ProxyException message), leaking internal file
paths, line numbers, and call stacks to any caller. Two MCP route handlers
in proxy_server.py similarly interpolated str(e) into "Internal server
error" detail strings.

Fix: log the traceback server-side via verbose_proxy_logger.exception()
and omit it from the ProxyException payload / HTTPException detail returned
to clients. Tests updated to assert no "traceback" keyword or frame paths
appear in the 503 body, with a new dedicated regression test.

* fix(proxy/cwe-209): apply Greptile P2 fixes and add MCP exception-path tests

Greptile 4/5 review identified two remaining gaps and Codecov reported
0% coverage on the two MCP handler exception branches:

1. caching_routes.py — str(e) in "Service Unhealthy ({str(e)})" could
   still leak Redis hostnames/IPs; replaced with static "Service Unhealthy".
   HTTPException is now re-raised before the generic handler so the
   "cache not initialized" 503 still reaches callers with its detail.
   Removed the redundant str(e) arg from verbose_proxy_logger.exception()
   (exception() already appends the traceback automatically).

2. tests — two new unit tests cover the exception paths in
   dynamic_mcp_route and toolset_mcp_route that were previously at 0%:
   - test_dynamic_mcp_route_unexpected_exception_returns_500_without_traceback
   - test_toolset_mcp_route_unexpected_exception_returns_500_without_traceback

All 25 tests pass (9 caching + 16 MCP).

CWE-209: Generation of Error Message Containing Sensitive Information.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* test(caching_routes): restore precise assertion in test_cache_ping_no_cache_initialized

The assertion was weakened to `"Cache not initialized" in str(data)`, which
matches the raw string of the entire response dict and would pass even if the
error moved to an unexpected field or changed structure.

Restore a targeted check on the parsed response: assert the exact string in
the correct field `data["detail"]`, matching FastAPI's HTTPException
serialisation format {"detail": "<message>"}.

* test(caching_routes): restore precise assertion and add CWE-209 no-cache path test

The assertion in test_cache_ping_no_cache_initialized was weakened to
`"Cache not initialized" in str(data)`, which matched against the raw string
representation of the entire response dict. This would pass silently even if
the error message moved to an unexpected field or the structure changed.

Restore a targeted assertion on the parsed field:
  assert data["detail"] == "Cache not initialized. litellm.cache is None"
matching FastAPI's HTTPException serialisation format exactly.

Add test_cache_ping_no_cache_does_not_expose_internals to show the code path
is still working correctly after the CWE-209 fix: verifies that the HTTPException
is re-raised as-is (no traceback, no source paths), and asserts the complete
response structure is exactly {"detail": "Cache not initialized. litellm.cache is None"}.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(caching_routes): restore ProxyException envelope for null-cache 503

The except HTTPException: raise guard (added in the CWE-209 fix) caused
the null-cache HTTPException to escape as FastAPI's {"detail": "..."} shape
instead of the {"error": {...}} ProxyException envelope that callers expect.

Move the null-cache guard before the try block and raise ProxyException
directly so the response structure is consistent with all other /cache/ping
503s, and the except HTTPException: raise guard is only reachable by
unexpected downstream HTTPExceptions.

Update the two no-cache tests to assert the correct ProxyException envelope.

* Update utils.py (#26609)

* feat(pricing): add Snowflake Cortex REST API model pricing (#26612)

* feat(pricing): add Snowflake Cortex REST API model pricing

## Summary

Adds pricing and context window information for 20+ Snowflake Cortex REST API models to `model_prices_and_context_window.json`.

## What's included

- **7 Claude models** (sonnet-4-5, sonnet-4-6, 4-sonnet, 4-opus, haiku-4-5, 3-7-sonnet, 3-5-sonnet) — with prompt caching rates
- **4 OpenAI models** (gpt-4.1, gpt-5, gpt-5-mini, gpt-5-nano) — with prompt caching rates  
- **5 Llama models** (3.1-8b, 3.1-70b, 3.1-405b, 3.3-70b, 4-maverick)
- **1 DeepSeek model** (deepseek-r1)
- **1 Mistral model** (mistral-large2)
- **1 Snowflake model** (snowflake-llama-3.3-70b)
- **2 Embedding models** (arctic-embed-l-v2.0, arctic-embed-m-v2.0)

Each entry includes `input_cost_per_token`, `output_cost_per_token`, `cache_read_input_token_cost` (where applicable), `max_input_tokens`, `max_output_tokens`, and capability flags (`supports_function_calling`, `supports_vision`, `supports_prompt_caching`, `supports_reasoning`).

## Pricing source

All prices are in USD per token, sourced from the official [Snowflake Service Consumption Table](https://www.snowflake.com/legal-files/CreditConsumptionTable.pdf) — Tables 6(b) (REST API with Prompt Caching) and 6(c) (REST API).

## Context

The existing `snowflake/` provider has zero model entries in the pricing JSON, which means LiteLLM cannot track costs for Snowflake Cortex calls. This PR fills that gap.

* fix(utils): copy extra_body before adding unknown params to prevent model config mutation (#29620)

Fixes #29615. In add_provider_specific_params_to_optional_params, the line:

    extra_body = passed_params.pop("extra_body", None) or {}

returns the original dict reference when extra_body is non-empty (truthy).
Subsequent writes like extra_body[k] = passed_params[k] then mutate the
shared model config object held by the router, poisoning /model/info and
all subsequent requests for that deployment.

The or {} short-circuit creates a new dict only when extra_body is falsy
(None or {}), which is why the bug does not reproduce with extra_body: {}.

Fix: wrap in dict() so we always work on a fresh shallow copy.

* fix(gemini/veo): move image from parameters into instances[0]

Veo's predictLongRunning schema puts image (and prompt) on the
instances element; parameters is for aspectRatio/durationSeconds/etc.
The Gemini path was leaving image in params_copy, so it ended up
nested under parameters and the API silently ignored it.

The Vertex path already builds the instance dict explicitly, so this
just aligns the Gemini path with it.

Fixes #29498

* address greptile: unconditional pop + BytesIO test

- Pop `image` from params_copy unconditionally so it never reaches
  GeminiVideoGenerationParameters even when None, removing implicit
  reliance on Pydantic's extra-field-ignore.
- Add test_transform_video_create_request_image_filelike_goes_to_instance
  covering the BytesIO path (_convert_image_to_gemini_format) — round-trips
  the base64 to confirm encoding.
- Add test_transform_video_create_request_image_none_is_dropped covering
  the new None branch.

* fix(huggingface): handle special token text in embedding usage (#29660)

* fix(guardrails): recompile ToolPermissionGuardrail rules on update_in_memory_litellm_params (#29655)

* fix(guardrails): recompile ToolPermissionGuardrail rules on update_in_memory_litellm_params

ToolPermissionGuardrail builds self.rules and the compiled target/pattern
maps only in __init__. The base update_in_memory_litellm_params re-sets raw
attributes via setattr but never rebuilds those maps, so a guardrail updated
in place (PUT /guardrails, or the immediate in-memory sync) keeps enforcing
the construction-time rules until it is reinitialized (PATCH path, periodic
DB poll, or restart).

Extract the compile step into _load_rules and override
update_in_memory_litellm_params to rebuild from it (dict- and model-safe),
re-normalizing default_action / on_disallowed_action. Mirrors the existing
PresidioGuardrail override of the same method. Adds regression tests.

Fixes #29592.

* fix(guardrails): handle dict params in ToolPermissionGuardrail in-memory update

Delegate to super() only for LitellmParams input (the base setattr loop is
model-only); apply the raw-dict case inline. Fixes the mypy arg-type error
and makes the recompile work when the proxy passes the raw DB dict.

* fix(guardrails): preserve tool-permission rules on a partial in-memory update

A partial update (e.g. a LitellmParams whose rules field is None) ran through
the generic setattr, which set self.rules to None, and the recompile was
skipped, leaving the guardrail with no rules. Snapshot the previous rules and
restore them when the update carries no rules; an explicit empty list still
clears them. Adds a regression test for the rules-absent case.

Addresses the Greptile review note on #29655.

* fix(bedrock): stop base_model label from stripping tools/tool_choice (#29621)

* fix(bedrock): stop base_model label from stripping tools/tool_choice

A Router/proxy Bedrock deployment whose model_info.base_model is a friendly
label (e.g. claude-haiku-4-5) silently lost tools/tool_choice: the outgoing
Converse request was built without toolConfig, so the model behaved as if no
tools were provided. Worked in v1.84.0, regressed in v1.85.0, and with
drop_params=true it failed silently.

Two changes compound into the bug. completion() passed model_info.base_model
as the model argument to get_optional_params, so the real Bedrock model id
never reached supported-param resolution; and get_supported_openai_params
resolved the provider config's params from base_model or model, letting the
label fully replace the real model. For Bedrock the label resolves to no tool
support, so tools/tool_choice were dropped before transformation.

completion() now keeps model as the real deployment model and threads the
resolved base_model (kwarg or model_info) through separately, and
get_supported_openai_params treats base_model as additive: it returns the
union of the params supported by model and by base_model. A hint can only add
capabilities, never strip ones the real model already exposes, which also
preserves the original base_model behavior from #27717 and Azure's base_model
driven model-type detection.

Fixes #29618

* test(main): make base_model param test robust to new parametrize cases

Restore an explicit per-case expected_model_param literal instead of
hardcoding the gemini id, so a future case with a different model can't
produce a misleading assertion failure.

* fix(fireworks_ai): pass response_format json_schema through unchanged (#29606)

FireworksAIConfig.map_openai_params was rewriting the OpenAI strict
`{type: json_schema, json_schema: {name, strict, schema}}` shape into
`{type: json_object, schema: ...}` before sending to Fireworks, dropping
`strict` and `name` and changing the `type`. Per Fireworks' docs json_object
means "force any valid JSON output (no specific schema)", so the schema
constraint was effectively dropped and grammar-guided decoding never ran;
model output silently violated the schema.

The rewrite landed in #7085 (Dec 2024) when Fireworks did not yet accept
native json_schema. Fireworks accepts the OpenAI strict shape natively now,
so the rewrite has become a regression.

Removes the rewrite. Passes response_format through unchanged. Updates the
existing test_map_response_format to assert pass-through. Adds focused
regression tests in tests/test_litellm/ covering preservation of type,
strict, name, and schema body, plus that json_object alone still works.

* fix(test): use .value when comparing LlmProviders enum against string in test_default_api_base

* fix(test): iterate LlmProviders enum in test_default_api_base to avoid str pollution from custom provider registration

litellm.provider_list is a mutable global initialized to list(LlmProviders) but custom_llm_setup() appends plain provider strings to it. When a test_custom_llm.py test runs first in the same xdist worker, provider_list contains a str and calling .value on it raises AttributeError. Iterate the immutable LlmProviders enum instead, which is deterministic and what the check intends.

* fix(mcp): depth-aware JSON-RPC response detection and neutral speed-priority fallback

Replace the flat substring check in the truncated-body routing path with a
top-level-key scan so a JSON-RPC response whose result payload nests a
"method" field is still detected as a response and skips the session lock,
removing a deadlock against the in-flight tool call awaiting it.

Drop the inverse max_output_tokens speed proxy when no model exposes
output_tokens_per_second; context-window size does not track latency, so a
neutral score avoids biasing speedPriority toward the smallest-context model.

* fix(guardrails): make ToolPermission rule reload atomic on invalid regex

_load_rules appended each rule to self.rules before compiling its regex, so an
invalid pattern raised mid-loop after the bad rule was already live but without
a _compiled_rule_targets entry. _matches_regex reads a missing compiled target
as a None pattern and returns True, turning the bad rule into a match-all that
silently applies its decision to every tool. Via update_in_memory_litellm_params
(PUT /guardrails) this corrupted the live guardrail.

Build the parsed rules and compiled maps into locals and swap them in only after
every regex compiles, and restore the previous ruleset if a live update is
rejected, so an invalid regex now fails the update without leaving the guardrail
enforcing a broken policy.

* test(mcp): cover sampling conversion, model resolution, and elicitation relay paths

The MCP sampling and elicitation handlers shipped with partial test
coverage, leaving the response-to-MCP conversion, the model resolution
fallback chain, completion-kwargs assembly, guardrail routing, and the
entire elicitation relay untested. That pulled the PR's diff (patch)
coverage below the codecov threshold even though overall project
coverage rose.

Add focused unit tests for _convert_openai_response_to_mcp_result,
_convert_mcp_tools_to_openai, _convert_mcp_tool_choice_to_openai, image
and audio content conversion, the hint-matching and fallback branches of
_resolve_model_from_preferences, _build_completion_kwargs, the router and
guardrail-rejection paths of _run_guardrails_and_call_llm, the
handle_sampling_create_message success and error-propagation flows, the
marker-hoisting fallback for tool content on unexpected roles, and the
elicitation form/url/generic relay together with its decline paths

4a81ec4982 feat(proxy): add per-MCP-server RPM rate limiting for keys and teams (#29482)
* feat(proxy): add per-MCP-server RPM rate limiting for keys and teams

Adds mcp_rpm_limit, a dict keyed by MCP server name (alias if set, else the
configured name) that caps requests per minute per server for a key or team.
The v3 rate limiter builds a per-server descriptor only when a limit is
configured for the server being called, so other servers stay uncapped and no
TPM reservation is engaged. Server identity is surfaced into the request data
via mcp_rate_limit_server_name so the limiter can resolve it.

* fix(proxy): gate MCP rpm descriptors on call_mcp_tool; document mcp_rpm_limit param

Only honor mcp_server_name when the call is an actual MCP tool call. Without
this, a normal LLM request could inject mcp_server_name in its body to consume
a target server's MCP quota and 429 legitimate tool calls. Also adds the
mcp_rpm_limit parameter docstring to update_key, new_user, and user_update so
the API docs validator passes.

* Fix MCP rate limit quota handling

* Delete scripts/test_mcp_rpm_limit.sh

* docs(proxy): clarify mcp_rpm_limit is enforced for keys and teams, not per user

* fix(proxy): accept mcp_rpm_limit in generate_key_helper_fn

NewUserRequest and GenerateKeyRequest inherit mcp_rpm_limit from
GenerateRequestBase, so /user/new and /key/generate forwarded the field
to generate_key_helper_fn, which did not accept it and returned a 500
("unexpected keyword argument 'mcp_rpm_limit'"). Accept the param and
store it in metadata, matching model_rpm_limit/model_tpm_limit, so the
limit is persisted where get_key_mcp_rpm_limit reads it.

+5 6d6eda8101 [internal copy of #28008] Support MCP OAuth passthrough and issuer-scoped JWT auth (#28356)
* fix(proxy): point /metrics 401 at the opt-out flag

Operators upgrading past 35bbca60b0 (which made /metrics auth
default-on) see "Malformed API Key passed in. Ensure Key has 'Bearer '
prefix." with no hint that
litellm_settings.require_auth_for_metrics_endpoint: false restores the
previous unauthenticated behavior. Append that discovery hint to the
existing 401 body so a Prometheus scraper that breaks after upgrade
has a clear migration path. No behavior change.

* fix(proxy): bound budget reservation per request instead of pinning to remaining headroom

reserve_budget_for_request fell back to reserving the entire remaining
team/key/user headroom whenever a request omitted max_tokens, which
pinned the spend counter at max_budget for the duration of the
in-flight request and false-positive-blocked every concurrent or
back-to-back request until the success callback reconciled. Surfaced
as an integration-test team being budget-blocked at its $2000 cap
while DB spend was $0.144.

Switch the missing-max_tokens path to a fixed default of 16384 output
tokens (mirrors parallel_request_limiter_v3's DEFAULT_MAX_TOKENS_ESTIMATE
precedent), and clamp explicit max_tokens at the model's
max_output_tokens for reservation accounting only. The outbound request
body is unchanged, so providers see whatever the caller actually sent;
only the local integer used to compute reservation cost is bounded.
This also prevents a hostile max_tokens=999999999 from inflating one
request's reservation up to the entire team headroom.

For Opus 4.7 (output $25/M, max_output 128K) on a $2000 budget the
worst-case per-request reservation drops from "everything left" to
$3.20, raising admittable concurrency from 1 to ~625.

* fix(proxy): reserve per-image cost for image-generation requests

Image-generation routes (dall-e-3, flux, etc.) have no per-token output
cost so they fell through to the no-reservation read-time-only path.
Concurrent image requests against a depleted budget could all pass
common_checks (counter exactly at max_budget passes the strict-`>`
gate) and reach the provider before reconciliation caught up.

Add per-image reservation in _estimate_request_max_cost_for_model:
when the model has a per-image cost field, reserve `n × cost_per_image`
upfront. The atomic counter increment serializes concurrent admissions,
so the second request sees the post-first-reservation counter and
raises BudgetExceededError instead of silently leaking through.

Both `output_cost_per_image` and `input_cost_per_image` are honored —
naming is inconsistent across providers (OpenAI dall-e-3 uses
input_cost_per_image, aiml/dall-e-3 uses output_cost_per_image for
the same per-generated-image price).

Per-pixel pricing (DALL-E 2 size variants) and TTS/STT routes still
fall through to read-time enforcement; those are follow-ups.

* fix(proxy): gate image-gen reservation strictly on model mode

The previous detection treated any model with input_cost_per_image
or output_cost_per_image as image generation. Several chat and
embedding models carry those fields to price multimodal vision input,
not generated images:

- gemini-3.1-pro-preview (mode=chat) has output_cost_per_image=0.00012
  alongside input/output token pricing.
- azure/gpt-realtime-* (mode=chat) has input_cost_per_image=5e-6.
- amazon.titan-embed-image-v1 (mode=embedding) has
  input_cost_per_image=6e-5.

For these models the image-gen branch fired first and reserved a
fraction of a cent per request, short-circuiting the token-priced
path entirely. Long Gemini chats reserved 1 × $0.00012 instead of
the true token cost.

Gate strictly on mode in {"image_generation", "image_edit"}. All 197
real image_generation entries and all 31 image_edit entries
(Flux Kontext, Stability inpaint/outpaint, etc.) carry the right mode,
so the field-presence fallback was unnecessary.

Adds regression tests for the chat-model-with-image-cost-field case
and for image_edit reservation.

* build(packaging): relax core runtime pins to ranges

Backport of #27241 onto litellm_1.84.0rc2.

The 12 entries in `[project.dependencies]` were exact `==` pins, a side
effect of the Poetry -> uv migration. This forces every downstream
package that lists litellm as a dependency to downgrade common runtime
libraries (openai, pydantic, aiohttp, click, jsonschema, ...) to the
exact versions we ship.

Switch to lower-bounded ranges with upper bounds where the upstream
package is pre-1.0 or has a known breaking-major-version policy.
Reproducibility for our Docker proxy and CI continues to come from
`uv.lock`, which is regenerated here as a metadata-only diff.

Conflict resolution vs upstream merge:
- The upstream merge commit also surfaced unrelated context entries
  (nvidia-riva-client, soundfile/stt-nvidia-riva extra) that exist in
  staging but not in rc2. Those are not part of #27241's intent and
  were dropped from the resolution; the rc2 uv.lock keeps its existing
  entry set, only the 12 specifier strings changed.
- `uv lock --check` passes (392 packages resolved, no drift).

* build(packaging): raise jinja2 floor to 3.1.6

Our `uv.lock` already resolves jinja2 to 3.1.6, so Docker / CI installs
get that version. The `pyproject.toml` floor was lagging at 3.1.0,
which means downstream consumers using `--resolution=lowest-direct` or
older constraint files can land on 3.1.0-3.1.5 instead of the version
we actually test against.

Aligns the declared floor with the resolved version so external
installers see the same baseline our test matrix exercises.

`uv lock` diff is metadata-only (no resolved-version drift).

* fix(mcp): forward extra_headers for OpenAPI MCP tools

OpenAPI-generated tools only applied static closure headers and BYOK
Authorization via ContextVar. Copy MCPServer.extra_headers from the
incoming MCP request into _request_extra_headers (set in server.py before
local tool dispatch), merge in openapi_to_mcp_generator via a small helper.

OAuth2 M2M: do not forward caller Authorization from raw_headers (same rule
as _prepare_mcp_server_headers for managed MCP).

comment.

* fix(mcp): static headers win over forwarded headers in OpenAPI MCP

Match the existing MCP invariant in merge_mcp_headers and the managed MCP
path: operator-configured static headers always override caller-forwarded
headers on name conflict, with case-insensitive comparison so different
casing cannot bypass the precedence. _request_auth_header (BYOK) still
overrides Authorization last.

* fix(proxy): always merge caller-supplied tags into request metadata

Caller-supplied tags (`x-litellm-tags` header, body `tags`, `metadata.tags`)
were silently dropped unless the key/team had
`metadata.allow_client_tags: true` set. Restore the documented behavior:
tags from the request always flow into `metadata.tags` and union with any
admin-configured static tags from key/team/project metadata.

Removes the `allow_client_tags` opt-in flag from the pre-call pipeline.
The flag was only ever read here; it has no schema or endpoint footprint,
so leftover values in existing key metadata are inert.

Test cleanup mirrors the simplification: drop the three tests that
verified the strip-when-not-opted-in path, drop the `allow_client_tags`
fixture lines from the merge/union tests.

* docs(proxy): refresh stale comments referencing removed tag strip

The tag-strip block was removed in the parent commit but two surrounding
comments still referenced "tags without opt-in" and "runs AFTER the
strip". Update them to describe the remaining user_api_key_* and
_pipeline_managed_guardrails strip that the snapshot/merge ordering
actually protects against.

* Strip SERVER_ROOT_PATH before lazy-feature prefix match

LazyFeatureMiddleware compared the raw scope path against registered
prefixes (e.g. /policies), so requests under a server root path like
/api/v1/policies/... never matched, the feature never loaded, and the
endpoint returned 404. Strip the configured root path before matching,
normalizing trailing slashes and enforcing a component boundary so
/api does not falsely match /apiv2.

* Cache normalized SERVER_ROOT_PATH at middleware init

SERVER_ROOT_PATH is a process-startup env var. Read it once in
__init__ instead of calling get_server_root_path() + rstrip on every
request that arrives before all lazy features have loaded.

* chore(proxy): backport /key/regenerate ownership-rebind + premium-gate guards (#27793)

Backport of #27793 onto litellm_1.84.0rc2.

A non-admin caller could rebind their own key's user_id via /key/regenerate.
_execute_virtual_key_regeneration had org/team guards but no user_id guard,
and prepare_key_update_data did not strip the field — it survived
model_dump(exclude_unset=True) into the Prisma update. On the next request,
_return_user_api_key_auth_obj resolved the rebound user_id against
litellm_usertable and returned PROXY_ADMIN whenever the target row's
user_role was admin.

/key/update had the equivalent guard inline at _validate_update_key_data;
extract it to a shared helper _validate_caller_can_change_key_ownership and
call from both /key/update and _execute_virtual_key_regeneration.

Also tighten the premium gate that allowed the master-key rotation branch to
skip the enterprise check. The previous predicate was a field-presence test,
not an identity check. Verify the caller actually holds the master key via
_is_master_key before allowing the non-premium path.

Block explicit-null user_id and empty-string user_id as removal attempts;
both 403-reject for non-admin callers.

* fix(proxy): expose db status on public /health/readiness

Backport of #27866 onto litellm_1.84.0rc2.

External readiness probes consumed the legacy detailed payload's `db`
field to drive alerting and pod-rotation decisions. Stripping the body
to {"status": "healthy"} broke those probes silently — the HTTP code
still flipped to 503, but probes checking body.db == "connected"
treated the response as healthy.

Add `db` back to the unauthenticated payload. The rest of the diagnostic
fields (litellm_version, callbacks, cache, log_level) stay behind
/health/readiness/details so the recon-leak gate from #26912 holds.
Values match the legacy contract: "connected", "disconnected",
"Not connected". The 503-on-DB-disconnect behavior from LIT-2607 is
preserved.

* fix(ui): fetch version + debug flag from /health/readiness/details

The proxy moved `litellm_version`, `is_detailed_debug`, and other
diagnostic fields off the public `/health/readiness` payload behind
an auth-gated `/health/readiness/details` endpoint. The navbar
version tag and the detailed-debug-mode banner stopped working
because they were still reading those fields from the unauthed
response, which no longer contains them.

Replace `useHealthReadiness` with a `useHealthReadinessDetails`
hook that takes an `accessToken` argument and sends a Bearer header
to the auth-gated endpoint. The hook stays disabled while
`accessToken` is falsy, so the navbar can keep rendering on the
public model hub (where the token is null) without triggering an
auth redirect or a 401-loop.

* fix(ui): disable retries on readiness/details + cover token forwarding

Two small follow-ups on the readiness/details migration:

- Set `retry: false` on the query. The payload feeds a passive
  navbar tag and a debug banner; a 401 from an expired token
  shouldn't fan out into three retries against the proxy.
- Add navbar specs that assert the `accessToken` prop is forwarded
  into the hook (matches the DebugWarningBanner spec). Without
  this, the navbar could silently regress to passing `undefined`
  and the existing tests wouldn't catch it.

* fix: block client-side pricing injection via request body

Authenticated clients could supply CustomPricingLiteLLMParams fields
(input_cost_per_token, output_cost_per_token, etc.) in the request body.
These were forwarded to register_model() in main.py, permanently mutating
the shared global litellm.model_cost dict for all users on the instance.

Adds all CustomPricingLiteLLMParams fields to _BANNED_REQUEST_BODY_PARAMS
so is_request_body_safe() rejects them before they reach completion().
New pricing fields added to CustomPricingLiteLLMParams are auto-covered.

Admin opt-in via allow_client_side_credentials or
configurable_clientside_auth_params still works as before.

* fix: block SSRF fields in RAG ingest vector_store config

aws_sts_endpoint, aws_web_identity_token, and aws_bedrock_runtime_endpoint
in ingest_options.vector_store were passed directly to the Bedrock ingestion
class, which reads them into boto3 STS client construction. Any authenticated
caller could redirect AssumeRole calls to an attacker-controlled server,
leaking the proxy's instance profile credentials.

Calls is_request_body_safe() on ingest_options["vector_store"] before
forwarding to litellm.aingest(). Same banned-params list and admin opt-in
escape hatch (allow_client_side_credentials) as the /chat/completions path.
ValueError from the safety check is caught and re-raised as HTTP 400.

* fix: harden /key/update authorization checks (#27878)

* fix: patch Host-header auth bypass in get_request_route

Starlette reconstructs request.url from the Host header. A malformed
Host like `localhost/?x=1` causes Starlette to build the full URL as
`http://localhost/?x=1/health`, which url-parses to path="/". Since "/"
is in LiteLLMRoutes.public_routes, all protected routes became reachable
without authentication.

Fix: read scope["path"] (set by uvicorn from the HTTP request line,
not derivable from headers) instead of request.url.path. Sub-path
deployments are handled via scope["app_root_path"] / scope["root_path"],
mirroring Starlette's own base_url construction logic.

Affected variants confirmed fixed:
  Host: localhost/?x=1
  Host: localhost:4000/?x=1
  Host: localhost/#test
  Host: localhost:4000/#test

* fix: block credential fields in RAG ingest vector_store options

Credential fields (vertex_credentials, aws_access_key_id, api_key, etc.)
in ingest_options.vector_store are now rejected at the API boundary with
a 400 error. Credentials must be configured server-side.

Previously any authenticated user could supply a vertex_credentials dict
with type=external_account pointing credential_source.file at an
arbitrary path (e.g. /proc/1/environ) and token_url at an
attacker-controlled server. google-auth's identity_pool.Credentials
refresh() would read the file and POST its contents to the attacker.

* fix: block /key/update self-escalation by assigned users

Non-admin users who were assigned a key (created_by != caller) could
update any non-budget field — models, rpm_limit, guardrails, etc. —
without admin authorization, allowing privilege self-escalation.

Gate: only the key creator (created_by == caller) may edit their own
key without admin check; budget changes always require admin regardless
of creator status. All other callers must pass _check_key_admin_access.

* fix: block user-controlled api_base in RAG ingest vector_store options

A user-supplied api_base in ingest_options.vector_store caused the server
to forward its configured provider credentials (Gemini, OpenAI) to an
attacker-controlled endpoint via SSRF.

Add api_base to the blocked credential params set alongside api_key and
the existing credential fields.

* fix: restrict /utils/transform_request to PROXY_ADMIN and apply body safety check

Any authenticated internal_user could POST arbitrary provider config
(aws_sts_endpoint, api_base, etc.) to /utils/transform_request and have
the server forward its credentials to an attacker-controlled endpoint.

- Gate the endpoint on PROXY_ADMIN role (403 for all other roles)
- Call is_request_body_safe() to reject banned params even for admins
- Convert ValueError from safety check to HTTP 400

* fix: apply banned-param check to /utils/transform_request

Without is_request_body_safe(), any authenticated user could pass
aws_sts_endpoint, api_base, or aws_web_identity_token to
/utils/transform_request and have the server forward its configured
provider credentials to an attacker-controlled endpoint during SDK
credential resolution.

Applies the same banned-param blocklist already used by LLM endpoints.
Endpoint remains accessible to all authenticated users.

* fix: block SSRF via api_base in /prompts/test dotprompt YAML frontmatter

Any frontmatter key not in ["model","input","output"] flowed into
optional_params and was merged into the LLM call data dict, bypassing
is_request_body_safe. An attacker with any bearer key could set
api_base in YAML to redirect the outbound LLM request — including the
provider API key — to an attacker-controlled host.

Fix: call is_request_body_safe on the constructed data dict after
optional_params are merged, before invoking ProxyBaseLLMRequestProcessing.
ValueError from the banned-param check is surfaced as HTTP 400.

* fix: coerce nested config strings before banned-param check

_NESTED_CONFIG_KEYS descent used isinstance(nested, dict) which silently
skipped litellm_embedding_config when delivered as a JSON string via
multipart/form-data. Banned params (api_base, aws_sts_endpoint, etc.)
nested inside the stringified value were invisible to is_request_body_safe.

_NESTED_METADATA_KEYS already used _coerce_metadata_to_dict which parses
JSON strings before checking. Apply the same coercion to _NESTED_CONFIG_KEYS.

* fix: replace substring match with prefix match in is_llm_api_route

mapped_pass_through_routes used `_llm_passthrough_route in route` (substring)
so any admin-only path whose URL contained a provider name (openai, anthropic,
azure, bedrock, etc.) was misclassified as an LLM API route and bypassed the
admin gate in non_proxy_admin_allowed_routes_check.

Confirmed live: non-admin key could GET /credentials/by_name/openai (read
masked provider API key) and DELETE /credentials/openai (delete credential).

Fix: use exact match or startswith(prefix + "/") — the same pattern used
everywhere else in RouteChecks — so only routes that actually start with a
passthrough prefix are allowed through.

* fix: stabilize PR #27878 test failures

- key_management_endpoints: extend can_skip_admin_check to team keys so
  team members with /key/update permission can update non-budget fields.
  can_team_member_execute_key_management_endpoint already validates team
  membership + permission and raises if unauthorized; reaching the admin
  check on a team key means the caller was authorized.

- test: set created_by on mock key in
  test_update_key_non_budget_fields_allowed_for_internal_user so
  caller_is_creator resolves correctly (MagicMock default ≠ user_id).

- auth_utils.get_request_route: guard against non-dict request.scope
  (e.g. MagicMock in unit tests) to prevent a MagicMock leaking into
  UserAPIKeyAuth.request_route and failing Pydantic validation.

- ci: assign test_multipart_bypass_repro.py to the proxy-runtime shard
  in test-unit-proxy-db.yml to satisfy the shard-coverage check.

* fix: guard bare-/ root_path strip + make total_spend migration idempotent

auth_utils.get_request_route: when Starlette sets scope["app_root_path"]
to "/" (e.g. behind some middleware), the old stripping logic would
remove the leading slash from every path ("/team/new" → "team/new"),
breaking route matching and causing auth to misclassify protected routes.
Skip stripping when root_path is bare "/".

migration: add IF NOT EXISTS to total_spend ALTER TABLE so the migration
is safe to replay when a prior partial run already created the column.
Without this guard, prisma migrate deploy fails on CI DBs that were
partially migrated, causing all subsequent DB operations (including
/team/new) to 500.

* fix: require creator still owns key for personal-key bypass in /key/update

caller_is_creator now requires both created_by == caller AND user_id ==
caller. Previously checking only created_by let a demoted admin who
originally created a key for another user continue editing non-budget
fields on it after reassignment, bypassing _check_key_admin_access.

Adds regression test: creator whose key was reassigned is blocked (403).

* fix: extract auth checks to fix PLR0915 + broaden max_budget assertion

internal_user_endpoints._update_single_user_helper exceeded 50 statements
(PLR0915). Extract authorization checks into _check_user_update_authz helper
to bring statement count under the limit.

test_validate_max_budget: assert "negative" (substring of both the local
"cannot be negative" and the CI "non-negative finite number" messages) so
the test is stable regardless of which exact wording the function uses.

* security: prevent forwarding litellm api keys to upstream mcp servers

- Strip Authorization header from extra_headers for pass-through servers
- Pass-through servers (auth_type=None with extra_headers: [Authorization])
  must not receive the user's LiteLLM API key
- Only OAuth2 M2M and pass-through servers skip Authorization header
- Other headers (x-request-id, x-trace-id) are still forwarded normally
- Fixes credential leakage / authentication bypass in MCP pass-through mode

* fix(interactions): remove steps field not in google openapi spec

The steps field was added but is not present in the current Google
Interactions OpenAPI specification. Revert to using only the fields
that are actually defined in the spec.

* fix(mcp): forward Authorization in pass-through when x-litellm-api-key is admission

Commit 3753970cc9 widened the Authorization strip to cover all
is_oauth_passthrough servers — protecting against the LiteLLM admission
key leaking upstream when the caller used Authorization for admission,
but also silently stripping legitimate upstream OAuth bearers when the
caller used x-litellm-api-key for admission.

That broke transparent OAuth pass-through (EAI-506 V5/V6): standards-
compliant MCP clients (OpenCode, Claude Code, mcp-inspector) complete
PKCE against the upstream IdP and send the resulting token as plain
Authorization: Bearer per the MCP spec — with the wider strip in place,
that token never reaches the upstream and tools/list returns empty.

Narrow the strip: skip Authorization for pass-through servers only when
the caller did NOT supply x-litellm-api-key. When x-litellm-api-key is
present, admission is unambiguous and Authorization is free to carry
the upstream OAuth bearer.

The original security guarantee is preserved — a client that sends only
Authorization (no x-litellm-api-key) still has it stripped, so the
LiteLLM key cannot leak upstream via that path.

Tests:
- new: forwards Authorization when x-litellm-api-key is present
- new: still strips Authorization when only Authorization is present
- existing pass-through + M2M tests unchanged

* fix(interactions): align status enum with openapi spec

- Cache _get_agent_object_permission via user_api_key_cache (sentinel for

  every tool-list / tool-call.
- Re-raise HTTPException in handle_sse_mcp so 401 + WWW-Authenticate
  challenges (and other HTTP errors) propagate to SSE clients instead of
  being swallowed as 500.
- Normalise booleans in _validate_token_response so admin rules written as
  JSON-style "true" / "false" match upstream responses that return
  Python True / False.
- Treat configured JWT issuer claim mappings as advisory: when a mapped
  field is absent or empty, leave the normalised claim unset instead of
  raising, matching the global litellm_jwtauth path.

* test: replace dall-e-3 with gpt-image-1 in health check and router tests (#27813)

OpenAI returns 'The model dall-e-3 does not exist' for the test account,
breaking test_openai_img_gen_health_check and test_image_generation.
Switch to gpt-image-1, matching the existing TestOpenAIGPTImage1 pattern.

(cherry picked from commit aee58db880)

* fix(tests): drop dall-e-only test classes; route live image tests via gpt-image-1

Second wave of failures from the 2026-05-12 DALL-E shutdown:
- tests/image_gen_tests/test_image_edits.py::TestOpenAIImageEditDallE2
  and tests/image_gen_tests/test_image_generation.py::TestOpenAIDalle3
  are explicitly named for the deprecated models and can't pass; remove.
  gpt-image-1 coverage already exists in sibling classes.
- tests/local_testing/test_router.py image gen tests use dall-e-3 only
  as a routing example; swap to gpt-image-1.
- tests/local_testing/test_custom_callback_input.py image_generation
  success/failure paths swapped to gpt-image-1.

(cherry picked from commit 945b10ded4)

* test(fireworks): replace deprecated llama-v3p3-70b-instruct model

Fireworks removed llama-v3p3-70b-instruct from serverless, so every
live test using it now fails with NotFoundError ("Model not found,
inaccessible, and/or not deployed").

Swap the 6 references (3 files) to the currently-served
accounts/fireworks/models/deepseek-v3p1 — the canonical model in
Fireworks' current docs examples and present in LiteLLM's cost map.
test_get_model_params_fireworks_ai is a pure pricing-heuristic test
(no network) asserting the >16b branch, so it uses llama-v3p1-70b-
instruct instead to keep the "fireworks-ai-above-16b" assertion and
branch coverage intact.

(cherry picked from commit 39a1d438f2)

* test(fireworks): mock remaining live smoke tests

test_completion_fireworks_ai and test_completion_cost_fireworks_ai
made real Fireworks calls and broke whenever Fireworks rotated its
serverless catalog (no externally-verifiable model list exists).
They also asserted nothing — just printed.

Mock the HTTP post and assert real behavior instead: the request is
built with the right model/messages and the OpenAI-compatible
response parses back; the cost path yields a non-zero cost against
the local cost map. No network, no model dependency, stronger than
the old smoke checks.

* fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 (#28281)

* fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5

OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so the live audio
calls in test_stream_chunk_builder_openai_audio_output_usage and
test_standard_logging_payload_audio now hard-fail with a model-not-found
error on every PR. The error was not "openai-internal", so the except
block swallowed it and execution fell through to an unbound
completion/response (UnboundLocalError).

Switch both tests to gpt-audio-1.5, OpenAI's recommended successor
(GA, not deprecated, already present in the litellm cost map so the
response_cost assertion still resolves). Also broaden the except to
skip with the real error in the reason instead of crashing, so a
transient upstream blip can't reintroduce the UnboundLocalError.

* fix(tests): narrow audio-test skip to model-not-found, re-raise the rest

Address review feedback: an unconditional skip on any exception would
silently mask a litellm-internal regression in the audio path (broken
param transformation, serialization, bad header) instead of failing CI.

Skip only on the upstream-unavailable class (model_not_found / "does not
exist" / openai-internal) and re-raise everything else, so genuine
regressions still fail loudly. The UnboundLocalError is still fixed
because the handler either skips or raises - it never falls through.

* fix(tests): add budget_exceeded to expected Interaction status enum

Staging added budget_exceeded to the Interaction OpenAPI status enum; the staging merge into this branch picked up the spec change but not the matching test update, so test_status_enum_values failed in CI. Align the test's expected list (exact-match by design) with the live spec.

* fix(tests): mock HTTP fetch in test_img_url_token_counter

The test parameterized a live third-party image URL (blog.purpureus.net) which now 404s, causing get_image_dimensions to fall through to its base64 decode path and crash with 'not enough values to unpack' on every PR run. Mock safe_get with a tiny 1x1 PNG so the URL branch is still exercised without any network dependency.

* fix(tests): swap gpt-4o-audio-preview to gpt-audio-1.5 in test_gpt4o_audio

OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so both live tests in test_gpt4o_audio.py (test_audio_output_from_model and test_audio_input_to_model) hard-fail model_not_found on every PR. Swap the hardcoded model to OpenAI's successor gpt-audio-1.5 (same chat-completions audio surface; already in the litellm cost map). Mirror the narrowed-skip pattern from the prior audio fixes: skip on model_not_found / does-not-exist / openai-internal, re-raise everything else so genuine litellm regressions still fail CI loudly.

(cherry picked from commit 92de7423ef)

* fix(tests): migrate realtime + rerank tests off shut-down upstream models (#28191)

* fix(tests): use gpt-realtime in realtime guardrails test

OpenAI shut down gpt-4o-realtime-preview-2024-12-17 on 2026-05-07, so
the live OpenAI realtime guardrails integration test now fails with
model_not_found (session.created never arrives, _wait_for_event times
out). Point OPENAI_REALTIME_URL at the current GA model, gpt-realtime.

Scope limited to this test: the pricing-catalog JSON keeps the retired
entries intentionally (historical cost calc + separate Azure timeline),
and the Azure realtime cost-calc test is unaffected.

* fix(tests): mock nvidia_nim rerank instead of hitting EOL'd endpoint

NVIDIA reached end-of-life for the hosted nvidia/llama-3.2-nv-rerankqa-1b-v2
rerank API on 2026-05-18 with no published replacement, so the live
BaseLLMRerankTest.test_basic_rerank for nvidia_nim now returns HTTP 410
("Gone"). NVIDIA's hosted catalog rotates on a schedule, so swapping in
another live model would only defer the failure.

Override test_basic_rerank in TestNvidiaNim to mock the sync/async HTTP
transport (same pattern as test_nvidia_nim_rerank_ranking_endpoint in this
file) and inject a fake NVIDIA_NIM_API_KEY via monkeypatch. The
request/response transformation and cost calculation stay covered offline.
Scope limited to nvidia_nim; other BaseLLMRerankTest providers untouched.

* fix(tests): migrate remaining realtime tests off shut-down gpt-4o-realtime-preview

OpenAI's 2026-05-07 shutdown removed the entire gpt-4o-realtime-preview
family, including the undated 'gpt-4o-realtime-preview' alias (not just the
dated snapshot fixed earlier). Three live tests still connected with the
dead alias and failed with messages_received=1 (an error event instead of
session.created):

- test_openai_realtime_simple.py: get_model() -> gpt-realtime (drives
  TestOpenAIRealtime.test_realtime_connection / test_realtime_with_query_params)
- test_openai_realtime.py: test_openai_realtime_direct_call_no_intent and
  test_openai_realtime_direct_call_with_intent -> openai/gpt-realtime
  (the with_intent test shares the same dead alias even though it was not
  in the failing set this run)

Mocked unit tests (test_realtime_query_params_construction,
test_realtime_query_params_use_normalized_model_name) are left as-is: they
never hit the network and assert string plumbing only.

Also fixes test_text_message_blocked_by_guardrail_no_ai_response, which now
connects (the earlier URL swap worked) but tripped a model-wording-brittle
assertion. The guardrail flow asks the model to voice the block message
verbatim; gpt-4o-realtime-preview complied (output contained 'blocked'),
gpt-realtime refuses verbatim-repeat instructions ('I'm sorry, but I can't
repeat that message.'). Since the original user message is blocked before
it reaches OpenAI, the refusal is still a safe outcome. Assertion #3 now
accepts both voicing and refusal, and adds a hard check that the blocked
phrase never leaks into AI output.

* fix(model_prices): register mistral/ministral-8b-2512

Mistral's API now returns model='ministral-8b-2512' when 'mistral-tiny'
is requested, so test_completion_mistral_api fails with 'This model
isn't mapped yet'. Adding the entry so completion_cost can resolve the
cost for that response.

Author: Claude <noreply@anthropic.com>

* fix(mcp,auth): address greptile review concerns

- handle_sse_mcp now calls _raise_preemptive_401_for_unauthenticated_servers
  so SSE clients to pass-through OAuth MCP servers receive the RFC 9728
  401 + WWW-Authenticate challenge that the streamable-HTTP path already emits.
- get_request_route strips a trailing slash from root_path before length-based
  prefix removal so non-canonical ASGI root_path values like "/litellm/"
  don't strip the leading slash from the returned route.
- _mcp_oauth_user_api_key_auth's cookie JWT decode now passes
  options={"verify_aud": False} so a future revision of the UI session
  JWT containing an aud claim cannot silently downgrade the request to
  unauthenticated.

* fix(tests): backfill local model_cost into remote-fetched map

litellm.model_cost is loaded at import time from LITELLM_MODEL_COST_MAP_URL
(pinned to main), so pricing entries that exist only in this branch (e.g.
mistral/ministral-8b-2512, freshly added because Mistral's API now returns
this id from mistral-tiny) are absent at test time and completion_cost
lookups raise 'This model isn't mapped yet'. Backfill the in-tree backup
into litellm.model_cost in the local_testing conftest so cassette-driven
cost calculations resolve against the entries that ship with the branch
under test.

Fixes local_testing_part1 failures on test_completion_mistral_api and
test_completion_mistral_api_modified_input.

* fix(mcp,jwt): address greptile concurrency and code-quality concerns

- _apply_issuer_claim_mappings now builds a new dict and reads from the
  original token, rather than mutating its input. The change is
  behaviour-preserving (caller passes a fresh jwt.decode result), but
  avoids the surprise-mutation pattern flagged by greptile.
- is_network_error uses isinstance(exc, httpx.TransportError) instead of
  matching type(exc).__name__ against a hand-maintained string set, so
  ReadError / WriteError / ProxyError / etc. are also treated as
  transport-level failures and surfaced as HTTP 502.
- fetch_upstream_oauth_protected_resource now coalesces concurrent
  discovery requests per (server_id, resource_url) through an
  asyncio.Lock so concurrent .well-known calls share a single upstream
  fetch + cache write.
- Drop the redundant 'if trusted_ranges:' branch in get_mcp_client_ip;
  it is always true on the path that reaches it (the prior 'if not
  trusted_ranges:' early-returns).

* fix(jwt,mcp): fall back to global JWKS on unknown issuer; prune fetch locks

- handle_jwt._get_configured_issuer now returns None for tokens whose 'iss'
  is not in the configured issuers list, letting auth_jwt fall through to
  the legacy JWT_PUBLIC_KEY_URL path instead of hard-raising. This keeps
  existing tokens from non-configured IdPs working when an operator adds
  the new 'issuers' list to a live deployment.

- discoverable_endpoints._prune_oauth_metadata_cache now also prunes
  entries in _OAUTH_METADATA_FETCH_LOCKS whose cache entry has been
  evicted and whose lock isn't currently held, bounding the locks dict
  to match the cache it guards.

* fix(mcp,auth): restore client_ip in oauth2 target check, drop from delegate check

The merge of staging into the PR branch (d42a66adb6) misplaced the
client_ip=client_ip kwarg: it landed inside _target_servers_delegate_auth_to_upstream
(which never accepted client_ip and isn't called with it), while the
sibling _target_servers_use_oauth2 has client_ip in its signature but
stopped passing it through to get_mcp_server_by_name. That left ruff
flagging F821 on the undefined name and lint failing.

Move client_ip back into _target_servers_use_oauth2's lookup (matching
the call site that already forwards IPAddressUtils.get_mcp_client_ip)
and drop it from _target_servers_delegate_auth_to_upstream so its body
matches its signature again.

* fix(mcp): respect client ip for delegated auth

* fix(auth): address remaining greptile style findings

- get_request_route: require root_path to match whole path segments before
  stripping, so '/apifoo' isn't truncated to 'foo' when root_path='/api'.
- get_mcp_client_ip: collapse the two trusted-proxy validation branches into
  a single is_request_from_trusted_proxy call so the return value drives
  control flow instead of being discarded for the side-effect warning.

* fix(jwt): strip internal _litellm_* claims in global JWKS auth path

Prevents identity spoofing where a token signed by the global JWKS
could inject _litellm_jwt_issuer and other _litellm_* claims that
downstream getters trust. The issuer-scoped path already strips these
via _apply_issuer_claim_mappings; mirror that behavior for the global
fallback path.

* fix(mcp): surface MCPUpstreamAuthError as 401 in SSE/HTTP transport handlers

Both handle_sse_mcp and handle_streamable_http_mcp only caught
HTTPException to preserve 401 + WWW-Authenticate challenges, but
MCPUpstreamAuthError (raised when a pass-through server's upstream
rejects a bearer token mid-session) inherits from Exception. It was
falling through to the generic handler and surfacing as an opaque 500.

Mirror the REST endpoint behavior: translate MCPUpstreamAuthError into
an HTTPException(status_code=e.status_code) with the upstream
www-authenticate header so standards-compliant MCP clients trigger the
upstream OAuth flow.

* fix(mcp): add upstream auth pre-flight in SSE handler

Mirror handle_streamable_http_mcp by calling _check_passthrough_upstream_auth
after the cold-start 401 emitter so expired/invalid upstream tokens surface a
proper 401 + WWW-Authenticate challenge before the SSE session commits 200
headers, instead of letting list_tools silently return [] when the upstream
rejects the token.

* fix(mcp): tighten cold-start bypass against CSV paths + dedupe upstream auth probe

- Return None from _parse_mcp_server_names_from_path for CSV multi-server
  paths (/mcp/a,b). The regex previously truncated at the first comma and
  silently passed a single server name to the cold-start gate.
- Switch _is_mcp_passthrough_cold_start to all-targets semantics, matching
  _target_servers_use_oauth2: one non-passthrough target in a co-targeted
  set must not flip the anonymous-admission bypass open for the others.
- Drop the redundant HTTPStatusError block in _extract_upstream_auth_failure
  - any HTTPStatusError carries a .response, so the preceding generic block
  already handles 401/403 detection.

* fix(mcp,tests): sync stubs and cold-start assertions with delegate-check

The merge of base-branch _target_servers_delegate_auth_to_upstream
into process_mcp_request inserts an additional
get_mcp_server_by_name(name) lookup ahead of the cold-start path,
which breaks two test patterns:

1. lookup_by_name(name) side-effect stubs in
   TestMCPDelegateAuthToUpstream are called positionally by the
   delegate check, then again by the cold-start path with
   client_ip=... — raising TypeError: unexpected keyword argument
   'client_ip'. Accept **_kwargs to match the real signature.

2. TestMCPPassthroughColdStartAdmission assertions count the lookup
   exactly once with client_ip=..., but the delegate check now adds
   a positional-only call ahead of it. Switch assert_called_once_with
   to assert_any_call for the cold-start invocation, and assert
   client_ip was *not* passed for the aggregate /mcp test where
   cold-start must not fire.

Both updates align with CLAUDE.md guidance to keep monkeypatch stubs in
sync with the real signature when an optional parameter is added.

* fix(mcp): correct passthrough probe 401 + slashed-name cold start parser

- _check_passthrough_upstream_auth now emits
  'Bearer resource_metadata="..."' pointing at the gateway's
  oauth-protected-resource well-known URL, mirroring the
  pre-emptive 401 path. Pass-through servers don't use the gateway
  as an authorization server, so the previous 'authorization_uri='
  challenge sent clients to the wrong metadata endpoint.

- _parse_mcp_server_names_from_path now accepts server names that
  contain a single slash (e.g. custom_solutions/user_123), mirroring
  MCPRequestHandler._extract_target_server_names_from_path. Without
  this, the cold-start bypass missed slashed-name servers and the
  generic admission error propagated instead of the spec-compliant
  401 challenge.

- _is_mcp_passthrough_cold_start drops the unused scope parameter
  from its signature.

* fix(mcp): handle passthrough OAuth metadata and startup auth errors

- discoverable_endpoints: For pass-through MCP servers, when upstream
  oauth-protected-resource returns a non-200/non-dict response, raise
  HTTP 502 instead of falling through to default gateway metadata.
  Falling through would direct MCP clients at the gateway, which is
  not the authorization server for pass-through configs.

- mcp_server_manager: Wrap _get_tools_from_server in startup tool name
  mapping with try/except. Since _get_tools_from_server now re-raises
  MCPUpstreamAuthError, an upstream 401 from a pass-through server at
  startup (when no user token is present) would otherwise abort the
  loop and leave subsequent servers unmapped.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): restrict passthrough probe challenge to OAuth passthrough servers

The probe filter previously matched any server with Authorization in
extra_headers, including gateway-managed OAuth2 servers. Those would
then receive the resource_metadata= WWW-Authenticate challenge meant
for pass-through servers, instead of the authorization_uri= challenge
pointing at the gateway AS metadata. Use srv.is_oauth_passthrough so
only genuine pass-through servers get the resource-metadata challenge.

* test(proxy): cover issuer-scoped JWT auth

* fix(mcp): use resource metadata for passthrough reauth

* fix(mcp,tests): assert cold-start helper directly for aggregate /mcp

Threading client_ip into _target_servers_delegate_auth_to_upstream
made get_mcp_server_by_name(name, client_ip=...) also fire from the
delegate-auth check, so the call_args_list assertion on
client_ip-in-kwargs no longer uniquely signals a cold-start lookup.
Patch _is_mcp_passthrough_cold_start and assert it is not invoked,
which is the actual contract the test is pinning.

* fix(mcp,jwt): drop unneeded async helper + suppress misleading unscoped JWT warning

- _build_oauth_authorization_server_response: revert to sync (no awaits in body).
  The function only does dict construction and synchronous registry lookups;
  async added coroutine creation overhead per discovery call without need.
- _build_decode_kwargs: accept has_issuer_config so the global path's
  'JWT auth is unscoped' warning is suppressed when LiteLLM_JWTAuth.issuers
  provides per-issuer scoping. Previously the warning fired spuriously for
  admins who intentionally use only the new issuers config.

* fix(jwt,mcp): clarify issuers fallthrough + add TTL on mcp permission cache

- LiteLLM_JWTAuth.issuers docs now state explicitly that unlisted
  issuers fall back to the global JWT_AUDIENCE/JWT_ISSUER path; the
  field is additive routing, not an allow-list. Matches actual
  control flow in handle_jwt.auth_jwt and the regression tests
  asserting backwards compatibility with the global JWKS path.
- MCPRequestHandler._get_{org,agent}_object_permission now pass
  ttl=DEFAULT_MANAGEMENT_OBJECT_IN_MEMORY_CACHE_TTL on async_set_cache,
  mirroring the auth_checks.py pattern so the cache TTL is explicit
  on both DualCache layers.

* fix(tests): align merged JWT and MCP cold-start assertions

Update the tests carried over from PR #28008 to match the assertions on
the staging branch:

- tests/test_litellm/proxy/auth/test_handle_jwt.py: unknown issuers now
  fall back to the legacy JWT_PUBLIC_KEY_URL path (per
  litellm_feat/v1.84.0-mcp-gateway-jwt-auth's
  '\''fall back to global JWKS on unknown issuer'\''), and mapped issuer
  claims that are absent no longer fail closed — they simply leave the
  normalised LiteLLM internal claim absent.

- tests/test_litellm/proxy/_experimental/mcp_server/auth/test_user_api_key_auth_mcp.py:
  the aggregate '\''/mcp'\'' route still triggers the delegate-auth-to-upstream
  lookup once for the header-supplied server name; cold-start admission
  must NOT fire on top of that. Tighten the assertion to
  assert_called_once_with so a future regression that re-enters cold-start
  is caught.

* fix(jwt): guard litellm_jwtauth access in auth_jwt global path

JWTHandler() can be constructed without update_environment() being
called (tests do this directly), in which case self.litellm_jwtauth
does not exist. Accessing it raises AttributeError before getattr can
fall back. Use the same safe pattern other call sites use.

* Gate MCP OAuth pass-through on delegate_auth_to_upstream flag

Sameer's review on #28356/#28008 flagged that the new pass-through
behaviors (preemptive 401 challenges, /.well-known/oauth-protected-
resource proxying, upstream 401/403 propagation as MCPUpstreamAuthError,
and Authorization-stripping when no x-litellm-api-key is supplied)
were implicitly enabled for every server with auth_type=none plus
Authorization in extra_headers. Existing users doing static bearer
pass-through for non-OAuth reasons would have silently regressed.

Make the detection rule explicit: extend the existing
delegate_auth_to_upstream flag (previously oauth2-only) to also gate
is_oauth_passthrough. Now requires flag + auth_type=None + Authorization
in extra_headers, per Sameer's suggested detection rule. The UI toggle
now appears for both modes (oauth2 PKCE passthrough and auth_type=none
OAuth pass-through) with mode-appropriate copy.

Update test fixtures to set the flag where the test intent is to
exercise OAuth pass-through behavior, and add negative tests covering
the new default-false case.

* fix(mcp): route org object_permission lookup through shared auth helpers

Replace the bespoke litellm_organizationtable.find_unique + dedicated
cache key in _get_org_object_permission with get_org_object +
get_object_permission so MCP requests share the same user_api_key_cache
entries as the rest of the proxy and no longer fragment org-row caching.

* fix(mcp): wrap get_object_permission call in shared try/except

Ensure exceptions from get_object_permission in _get_org_object_permission are caught and return None, preserving the original fail-safe semantics.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(jwt): validate issuer audience at config load + dedicated key-miss exception

- Move JWTIssuerConfig audience-required guard into a Pydantic model_validator
  so misconfiguration fails at startup instead of on the first request.
- Replace the string-match `No matching public key found` filter in
  get_public_key's multi-URL fallback with a dedicated
  NoMatchingJWTPublicKeyError; only that specific exception triggers
  continuation, every other error still surfaces.

* fix(mcp): admit and forward Authorization for passthrough OAuth return

For pass-through MCP servers (auth_type=none with delegate_auth_to_upstream)
the RFC 9728 cold-start flow sends the client back with only
"Authorization: Bearer <upstream-token>" after upstream OAuth discovery.
Previously this path 1) was rejected in process_mcp_request because the
oauth2_headers fallback only covered auth_type=oauth2 targets, and 2) had
the Authorization header stripped by _prepare_mcp_server_headers when no
x-litellm-api-key was present, treating the upstream token as a potential
LiteLLM key leak.

- Extend the elif oauth2_headers fallback to also admit anonymously when
  every target is a pass-through server.
- Pass user_api_key_auth into _prepare_mcp_server_headers so it can
  forward Authorization for pass-through servers when admission did not
  consume the bearer as a LiteLLM key (api_key is unset).

* fix(mcp): consistent www-authenticate casing + SSE toolset scoping

- Normalize the WWW-Authenticate header key emitted by
  _check_passthrough_upstream_auth to lowercase to match the other 401
  emitters in the OAuth pass-through flow.
- Mirror the streamable HTTP handler's toolset scoping in handle_sse_mcp:
  strip client-supplied x-mcp-toolset-id and apply _apply_toolset_scope
  before _check_passthrough_upstream_auth so the upstream probe list is
  derived from the fully-authorized server set.
- Tighten _has_client_supplied_mcp_auth signature so
  mcp_server_auth_headers is Optional, matching its caller in
  process_mcp_request.

* security(mcp): strip Authorization in call_tool when LiteLLM admission used legacy header

Mirror the OAuth pass-through admission check from _prepare_mcp_server_headers
(list-tools path) in _call_regular_mcp_tool (tool-call path): when the server
is OAuth pass-through and the caller did not supply x-litellm-api-key,
Authorization on the inbound request may itself be the LiteLLM API key — so
strip it before forwarding instead of leaking the gateway credential upstream.

When x-litellm-api-key is present, admission is unambiguous and Authorization
continues to carry the upstream OAuth bearer (transparent pass-through).

* refactor(mcp): centralize caller Authorization strip decision

Extracted the security-sensitive logic that decides whether the caller's
Authorization header is forwarded to (or stripped from) an outgoing MCP
request into a single helper, _should_strip_caller_authorization, in
mcp_server_manager.py.

Previously the same condition was duplicated across
_call_regular_mcp_tool (mcp_server_manager.py) and
_prepare_mcp_server_headers (server.py). Keeping two copies of this
check risked future divergence and credential-leak / broken-passthrough
bugs. Both call sites now share the helper, preserving exact behavior.

* log MCP OAuth discovery diagnostics for unmatched paths and non-transport upstream errors

* fix(jwt): include issuer-normalized team id in get_all_jwt_team_ids

The aggregator for team IDs only consulted the issuer-normalized claim
for the plural (team_ids) path and fell back to the global config for
the singular path. When an operator configures team_id_jwt_field only
at the issuer level, get_team_id correctly returned the mapped value
but get_all_jwt_team_ids silently dropped it, causing membership
reconciliation to disagree with request routing.

* fix(mcp/jwt): dedupe cold-start path parser; reject conflicting audience flags

- _parse_mcp_server_names_from_path now delegates to
  MCPRequestHandler._extract_target_server_names_from_path so the
  names used by the cold-start passthrough bypass cannot drift from the
  names used by downstream routing.
- JWTIssuerConfig now rejects the combination of audience and
  disable_audience_validation=True at validation time instead of
  silently ignoring the flag.

* fix(mcp): restrict passthrough cold-start bypass to 401 only

The new elif passthrough cold-start branch reused is_auth_error which
matches both 401 and 403. A 403 from user_api_key_auth indicates the
LiteLLM key WAS recognized but is forbidden (e.g. over budget / rate
limited); falling through to anonymous UserAPIKeyAuth() in that case
bypasses spend and rate-limit controls on passthrough servers.

Only trigger the cold-start anonymous admission on 401, which is the
signal that the bearer is an upstream OAuth token rather than a
recognized LiteLLM key.

* fix(jwt/mcp): warn on unscoped JWT fallback; route agent permission lookup through shared helper

- _build_decode_kwargs no longer suppresses the unscoped-fallback warning
  when LiteLLM_JWTAuth.issuers is set: tokens whose iss does not match
  any configured issuer still fall through to the global path, and that
  fallback is itself unscoped when JWT_AUDIENCE/JWT_ISSUER are absent.

- _get_agent_object_permission now caches the agent_id ->
  object_permission_id mapping and delegates the permission lookup to
  the shared get_object_permission helper, so the agent path reuses the
  same cache entries as the org / team / key paths.

* fix(mcp): fabricate resource_metadata challenge when upstream 401 omits WWW-Authenticate

When an upstream pass-through MCP server returns 401 without a
WWW-Authenticate header (non-compliant per RFC 7235 §3.1),
to_http_exception() now produces a synthetic Bearer challenge pointing
at the gateway's standard-pattern oauth-protected-resource well-known
endpoint for that server. This keeps MCP clients on the RFC 9728
discovery flow instead of receiving a bare 401 with no recovery hint.

* fix(jwt): make _get_decode_options explicitly control verify_iss

Previously, _get_decode_options only set verify_aud based on whether
audience was provided. The issuer JWT path relied on always passing
issuer=issuer_config.issuer to trigger PyJWT's default verify_iss=True,
making the helper's behavior implicitly dependent on caller behavior.

Now _get_decode_options accepts issuer as well, mirroring the verify_aud
handling and matching the dimensions handled by _build_decode_kwargs.

* fix(mcp): emit absolute resource_metadata URI in fabricated 401 challenge

Per RFC 9728 §3.2 the resource_metadata Bearer challenge must be an
absolute URI; strict MCP clients reject relative URIs and fail to
initiate discovery. MCPUpstreamAuthError.to_http_exception now accepts
the gateway base URL and prepends it when the upstream omitted
WWW-Authenticate, and all four call sites (streamable HTTP, SSE, and
the two REST tool-list paths) supply it.

* fix(mcp): correct 403 detail text and remove dead _list_tools_for_single_server duplicate

- MCPUpstreamAuthError.to_http_exception() now returns detail='Forbidden' for
  403 upstream responses (and 'Unauthorized' for 401), matching the
  _check_passthrough_upstream_auth pre-flight probe.
- Remove the shadowed first definition of _list_tools_for_single_server in
  rest_endpoints.py; the second definition was the live one and the dead copy
  was a maintenance trap.

* fix: address potential bugs in auth_utils, mcp discoverable endpoints, and mcp auth

- auth_utils.get_request_route: return '/' instead of empty string when
  raw_path exactly equals root_path so downstream route allowlist checks
  still see a leading slash
- discoverable_endpoints.fetch_upstream_oauth_protected_resource: also
  cache negative results (no upstream metadata) for a shorter TTL so we
  don't re-fetch on every discovery request and so the per-key fetch
  lock can be pruned
- user_api_key_auth_mcp: guard the oauth2_headers 401 cold-start
  passthrough bypass with _has_client_supplied_mcp_auth, matching the
  parallel bypass in the no-Authorization branch so MCP-auth-bearing
  requests don't silently downgrade to anonymous admission

* test(vertex): tolerate transient InternalServerError in google maps tool test

test_gemini_google_maps_tool_simple makes live calls to Vertex AI's Google
Maps grounding backend, which intermittently returns 500 INTERNAL ("Please
retry") — a transient upstream failure, not a LiteLLM bug. The test already
passes on RateLimitError; treat InternalServerError the same way so transient
Vertex-side failures don't fail CI.

* refactor(mcp): drop redundant has_client_credentials filter on passthrough probe

is_oauth_passthrough already requires auth_type in (None, MCPAuth.none),
which is mutually exclusive with has_client_credentials (auth_type ==
MCPAuth.oauth2), so the extra guard was always True and only added
confusion about whether a server could be both passthrough and M2M.

* feat(mcp): add dedicated oauth_passthrough flag for non-oauth2 pass-through

Previously is_oauth_passthrough reused delegate_auth_to_upstream — a flag
scoped to oauth2 servers (PKCE bypass) — to gate OAuth pass-through for
auth_type=none servers. Overloading it risked regressing existing
deployments that set delegate_auth_to_upstream, since the same flag would
silently start driving pass-through (discovery proxying, 401 challenges,
upstream 401/403 propagation) on non-oauth2 servers.

Introduce a separate oauth_passthrough opt-in so the two behaviors never
imply each other:
- MCPServer.is_oauth_passthrough now requires oauth_passthrough (not
  delegate_auth_to_upstream).
- Persist oauth_passthrough on LiteLLM_MCPServerTable (new column +
  migration) and wire it through config/DB load and API responses.
- UI splits the single toggle into two: "Delegate auth to upstream (PKCE
  passthrough)" for oauth2 and "OAuth pass-through" for auth_type=none
  servers forwarding Authorization.

Adds backend tests (property, round-trip, and a regression guard that
delegate_auth_to_upstream alone never enables pass-through) and UI tests
for the toggle split.

* fix(mcp): reconcile cold-start bypass with x-mcp-servers header and skip non-absolute WWW-Authenticate fabrication

- _parse_mcp_server_names_from_path now fails closed when the
  x-mcp-servers header introduces any target not present in the
  path-derived target set, closing a header/path mismatch where the
  cold-start passthrough bypass could otherwise admit anonymously
  while the header advertises a non-passthrough server.
- MCPUpstreamAuthError.to_http_exception no longer emits a relative
  resource_metadata URI when base_url is missing; per RFC 9728 3.2
  the URI must be absolute, so we skip fabrication entirely rather
  than send a challenge strict MCP clients will reject.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): fabricate path-aware resource_metadata URI for upstream 401

When MCPUpstreamAuthError.to_http_exception fabricates a
`WWW-Authenticate: Bearer resource_metadata=...` challenge (because
the upstream 401 omitted one), the URL now matches the inbound MCP
transport pattern the client originally used:

  - /mcp/{server_name}      -> /.well-known/oauth-protected-resource/mcp/{server_name}
  - /{server_name}/mcp      -> /.well-known/oauth-protected-resource/{server_name}/mcp

This mirrors the path-aware behaviour of
_get_passthrough_resource_metadata_url in server.py so strict
RFC 9728 \xA73.2 clients on legacy routes get a resource_metadata URI
aligned with the resource pattern they originally targeted.

* fix(jwt+mcp): tighten issuer-scoped claim type handling, RFC-quote authorization_uri, surface MCP upstream auth errors, defense-in-depth on decode options

- handle_jwt: when an issuer-scoped _litellm_team_ids claim exists but
  has an unexpected type, return [] instead of falling through to the
  global team_ids_jwt_field path (different claim semantically).
- handle_jwt: _get_decode_options/_decode_jwt_with_public_key now take
  an explicit disable_audience_validation flag; passing audience=None
  without it raises, so audience checks can't silently disappear if the
  model validator is ever bypassed. _auth_jwt_with_issuer forwards the
  flag from JWTIssuerConfig.
- mcp_server: quote the authorization_uri WWW-Authenticate parameter
  value (RFC 6750 / 9728 auth-param must be quoted-string), matching
  the pass-through path.
- mcp_server: in _fetch_and_filter_server_tools, re-raise
  MCPUpstreamAuthError so the outer streamable-HTTP handler can surface
  a proper 401 + WWW-Authenticate challenge instead of returning an
  empty tool list.

* chore(docker): align Dockerfile.non_root/Dockerfile.database to current wolfi-base SHA

The older sha256:3258be... pin has been intermittently returning 500/not-found
from cgr.dev, breaking the test-server-root-path GitHub Action and the
build_docker_database_image CircleCI job. Move both Dockerfiles onto the
same sha256:31da65... digest already in use by Dockerfile, gateway/Dockerfile,
backend/Dockerfile, and migrations/Dockerfile so the base image is consistent
across the repo.

* ci(docker): bump wolfi-base pin to current working digest

The previously aligned sha256:31da6565f35a... and the older sha256:3258be...
both return HTTP 500 from cgr.dev's manifest endpoint, breaking the
build_docker_database_image CircleCI job and test-server-root-path GitHub
Action. The current 'latest' tag resolves to sha256:5743937d521c... which
serves manifests normally, so move docker/Dockerfile.database and
docker/Dockerfile.non_root onto that digest.

* ci(docker): retry apk add in Dockerfile.database for apk.cgr.dev flakes

Mirror the retry-loop pattern from #28888 (which fixed backend/Dockerfile,
gateway/Dockerfile, and migrations/Dockerfile) into docker/Dockerfile.database.
The build_docker_database_image CI job has been intermittently failing with
"remote server returned error (try 'apk update')" when apk.cgr.dev flakes
mid-fetch; bumping the wolfi-base SHA doesn't address the mirror, only a
retry does.

Same explicit-failure form as #28888: exit non-zero on the 3rd miss instead
of silently succeeding because `sleep 5` was the last command in the
`&& break || sleep 5` chain.

* fix(mcp): scope preemptive 401 to toolset-narrowed server set

Move _raise_preemptive_401_for_unauthenticated_servers after toolset
scoping in both the StreamableHTTP and SSE handlers, and add an
optional allowed_server_ids parameter so passthrough/oauth2 servers
that the active toolset excludes no longer trigger a spurious 401
challenge. Without this, a client targeting a toolset whose scope
excludes a passthrough server could be pushed into an OAuth flow for
a server it would be 403'd on immediately after authentication.

* revert(docker): drop unrelated Wolfi bump and apk retry loop from MCP/JWT PR

These Docker changes are out of scope for the MCP OAuth passthrough + JWT
auth work and duplicate the build-reliability fix already merged to
litellm_internal_staging in #28888, which adds the same apk retry loop on
the componentized backend/gateway/migrations Dockerfiles and also fixes the
underlying nodeenv/libatomic root cause. Restoring docker/Dockerfile.database
and docker/Dockerfile.non_root to the base so this PR is purely the MCP/JWT
change.

* fix(mcp): surface upstream 403 challenges from REST tools/list

The single-server pass-through path converted an upstream MCPUpstreamAuthError
into an HTTPException, but list_tool_rest_api only re-raised 401s; an upstream
403 (valid token, insufficient scope) collapsed into a 200 response with
error=unexpected_error, so clients never saw the status or WWW-Authenticate
challenge needed to refresh scopes. Let MCPUpstreamAuthError propagate and
convert it once in list_tool_rest_api so both 401 and 403 reach the client,
while internal access/IP 403s keep the legacy error-dict shape.

* fix(mcp): fail closed for IP access control when XFF trusted ranges unset

When use_x_forwarded_for is enabled but mcp_trusted_proxy_ranges is not
configured, get_mcp_client_ip previously fell back to the direct peer IP.
Behind an internal reverse proxy that peer is the proxy's private address,
so every external caller was classified as internal and could reach MCP
servers with available_on_public_internet=false. Return an empty string in
that case so is_internal_ip treats the caller as external.

b98a656254 Add MCP semantic conventions to otelv2 (#29468)
* Add MCP semantic conventions to otelv2

Emit OpenTelemetry GenAI MCP tool-call spans from the v2 logger. A closed
call_mcp_tool request now produces a CLIENT span named "tools/call {tool}"
carrying mcp.method.name, gen_ai.operation.name=execute_tool, gen_ai.tool.name,
the upstream server name, and (opt-in, content-gated) tool arguments/result.

Adds the MCP and JSON-RPC attribute vocabulary to the semconv module, an
MCPToolCallSpanData payload built from StandardLoggingMCPToolCall, an
MCP_TOOL_CALL span role, and mapper support.

* Complete the MCP span-attribute vocabulary in otelv2 semconv

Add the remaining OTel GenAI MCP semconv attribute keys: gen_ai.prompt.name,
the network.* transport keys with their well-known NetworkTransport values, and
the client.* peer keys for MCP server spans. A test pins the full vocabulary so
a dropped or renamed key fails loudly.

* Populate mcp.session.id on MCP tool-call spans

Capture the mcp-session-id header (case-insensitively) at the tool-call entry
point and thread it through StandardLoggingMCPToolCall into the span, so spans
for stateful MCP sessions carry mcp.session.id. Stateless calls have no such
header and the attribute is simply absent.

* Test that stateless MCP calls omit mcp.session.id

ryan-crabbe-berriandGitHub 90b5104475 feat(mcp/auth): additive key access-group grants + opt-in member assignment (#29313)
* fix(mcp): make key.access_group_ids grants additive over team ceiling

A key whose unified access_group_ids grant a private MCP server was
having that grant intersected against its team's MCP ceiling, so a key
in a team scoped to other servers (or with no own scope) lost the
granted server entirely. Resolve access_group_ids once as ungated
additive grants and union them on top of the key/team ceiling instead
of folding them into the key scope that gets intersected.

* test(mcp): align key access-group tests with additive-grant model

The previous commit moved key.access_group_ids resolution out of the
intersected key ceiling (_get_allowed_mcp_servers_for_key) and into the
ungated additive grant path (_get_key_access_group_mcp_server_extras),
unioned on top of the team ceiling. Five tests from #28890/#29195 still
asserted the old gated / in-key-scope contract and failed:

- _get_allowed_mcp_servers_for_key now returns the object_permission
  ceiling only and never resolves access_group_ids; two tests now assert
  the group resolver is not called from that path (with and without an
  object_permission present).
- The extras path is ungated, so a group whose assigned_team_ids /
  assigned_key_ids exclude the caller still contributes its servers.
- The end-to-end test asserts the grant surfaces via the extras path
  rather than the base key path.
- Dropped test_key_access_group_ids_empty_returns_no_extras; the empty
  case is already covered by the extras family's no-groups test.

* feat(auth): gate member access-group assignment on keys behind opt-in

Non-admin team members could attach access_group_ids to keys they create
or update, letting them self-grant resources (MCP servers/models) the team
admin never intended. Add an opt-in KEY_ACCESS_GROUP_ASSIGNMENT team-member
permission (default-deny) enforced at /key/generate and /key/update; proxy
and team admins bypass. Surfaces automatically as a checkbox in the team
Member Permissions UI.

* fix(auth): gate access-group assignment on /key/regenerate too

RegenerateKeyRequest inherits access_group_ids and prepare_key_update_data
persists it, so a non-admin key owner could self-grant access groups by
regenerating. Apply the same opt-in member gate using the existing key's
team.

* test(auth): cover member access-group gate and additive MCP grants

Add unit tests for enforce_member_can_assign_access_groups (deny without
opt-in, allow with opt-in, and proxy-admin / team-admin / non-team-key
bypasses) and for _get_key_access_group_mcp_server_extras (no-auth and
no-resolved-servers return empty, resolved ids are expanded, errors
degrade to no grants).

yuneng-jiangandGitHub 94a043efb2 refactor(proxy/auth): normalize Bearer prefix in safe-hash helper (#29343)
* refactor(proxy/auth): normalize Bearer prefix in safe-hash helper

UserAPIKeyAuth._safe_hash_litellm_api_key now strips a leading
"Bearer "/"bearer " prefix before its existing sk-/JWT classification, so
the helper produces the same hashed output regardless of whether the
caller stripped the Authorization header prefix or passed the header
value through unchanged.

* refactor(proxy/auth): make Bearer-prefix strip case-insensitive

Per RFC 7235 the HTTP authorization scheme token is case-insensitive.
Replace the two-prefix loop with a single case-insensitive check so the
helper normalizes "Bearer ", "bearer ", "BEARER ", and any mixed-case
variant before classifying the remainder as sk- or JWT. The contract
test gains coverage of "BEARER " and "BeArEr ".

* test(mcp): align auth-handler test expectations with safe-hash helper

The two MCP auth tests asserted that UserAPIKeyAuth(api_key="Bearer ...")
retained the raw header bytes on the api_key field. _safe_hash_litellm_api_key
now normalizes that input — stripping the Bearer prefix and hashing the
resulting sk- key — so the expectations move to the normalized form:
the bare token in the parametrize case, and hash_token("sk-...") in the
backward-compat assertion. This matches what the real auth flow produces
(the builder strips Bearer and the DB stores the hashed token), so the
mocks now line up with production rather than with the un-normalized
validator output.

c792df64d2 feat(mcp): support stateless and stateful clients via session-id routing (#26857)
* feat(mcp): support stateless and stateful clients via session-id routing

- Add session_manager_stateful (stateless=False) alongside stateless
- Route by mcp-session-id: has ID → stateful, initialize (no ID) → stateful, else → stateless
- Peek POST body to detect initialize for routing; replay via wrapped receive
- Handle stale session IDs for both managers
- Add test_mcp_routing_initialize_to_stateful_no_session_to_stateless
- Update test_valid_mcp_session_id_is_preserved, test_concurrent_initialize_session_managers

Made-with: Cursor

* fix(mcp): respect stateful routing and harden initialize detection

Ensure streamable MCP requests are dispatched via the computed target session manager, and guard initialize detection against non-object JSON bodies. Update stale-session test patches to target the stateful manager so routing assertions remain correct.

Made-with: Cursor

* test(mcp): patch stateless/stateful managers in concurrency init test

Update concurrent session-manager initialization test to patch session_manager_stateless and session_manager_stateful directly, matching initialize_session_managers() behavior and preventing NameError from undefined mocks.

Made-with: Cursor

* Fix tests

* Fix tests

* Fix MCP stateful routing edge cases

* Fix stateful MCP auth context refresh

* Fix MCP stateful session cleanup

* fix(mcp): bind stateful sessions to creator and reject hijacks

Stateful mcp-session-id was usable by any authenticated proxy caller. Track
the session creator's hashed API key (or user_id) when a new session is
issued and reject mismatched callers with 403 before _set_or_update_auth_context
overwrites the stored MCPAuthenticatedUser. Also formats nested with-statements
in test_mcp_stale_session.py and fixes a pre-existing AsyncMock mismatch in
test_stale_mcp_session_id_is_stripped.

* fix(mcp): serialize concurrent requests on same stateful session

Bugbot's 'Concurrent requests share context' finding: _update_auth_context
mutates the single MCPAuthenticatedUser stored per session in place on
every request, so two requests sharing one mcp-session-id can overwrite
each other's mcp_servers / auth headers / oauth state / client_ip while
in-flight callbacks are still reading the same object.

Owner-binding alone narrows this to same-principal racing, but the
in-place mutation race remains. Add a per-session asyncio.Lock around
handle_request so concurrent same-session requests run sequentially. The
lock is allocated on demand and torn down with the rest of the session
state on DELETE / idle expiry.

Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>

* fix(mcp): include OAuth2 bearer in stateful session owner fingerprint

UserAPIKeyAuth() for OAuth2 passthrough has no api_key/user_id, so every
OAuth caller fingerprinted to "anonymous" and could hijack another OAuth
caller's mcp-session-id. Hash the upstream Authorization header into the
fingerprint as oauth:<sha256>.

* fix(mcp): don't hold stateful session lock for streaming GETs

The per-session lock wraps handle_request, so a long-lived GET (SSE
stream held open for the life of the session) would block every
subsequent POST on the same mcp-session-id. Only POST/DELETE mutate the
shared MCPAuthenticatedUser, so it's sufficient to serialize those —
GETs run lock-free and stream concurrently.

* fix(mcp): allow None user_api_key_auth in MCPAuthenticatedUser

The set_auth_context / _set_or_update_auth_context / _update_auth_context
helpers in server.py all accept Optional[UserAPIKeyAuth] and pass it
straight into MCPAuthenticatedUser, but the dataclass-style constructor
typed user_api_key_auth as required UserAPIKeyAuth. Mypy flagged this on
the stateful-routing branch:

  server.py:3227: error: Incompatible types in assignment (expression
    has type "UserAPIKeyAuth | None", variable has type "UserAPIKeyAuth")
  server.py:3255: error: Argument "user_api_key_auth" to
    "MCPAuthenticatedUser" has incompatible type "UserAPIKeyAuth | None";
    expected "UserAPIKeyAuth"

Widen the parameter type to Optional[UserAPIKeyAuth] to match the call
sites. Runtime behavior is unchanged.

* style: replace with new alias

* fix(mcp): fall back to client_ip in stateful session owner fingerprint

Addresses Greptile review on PR #26857: when no API key, user_id, or
OAuth bearer is available (e.g. unauthenticated/passthrough callers),
the owner fingerprint collapsed to a single 'anonymous' value, allowing
two unrelated callers to drive each other's stateful MCP sessions.

Fold client IP into the fingerprint as a fallback identity signal so
distinct anonymous sources do not share an owner identity.

* Fix active stateful MCP session cleanup

* test(mcp): cancel leaked stateful auth-context cleanup task

initialize_session_managers() spawns a real asyncio.create_task running
_cleanup_expired_stateful_session_auth_contexts(). The
test_concurrent_initialize_session_managers test was saving and
restoring the session-manager context-manager globals but did not save,
cancel, or restore _stateful_auth_context_cleanup_task.

Because pyproject.toml sets asyncio_default_fixture_loop_scope=session,
the event loop is shared across tests in the same session, so the
leaked task kept running against module-level dicts for the rest of the
test run. Save and cancel the task in the finally block so the test
fully cleans up after itself.

Authenticated clients that POST without an mcp-session-id forced the proxy

'initialize'. Cap the peek at 4 KB (more than enough for an initialize
envelope) and let the remainder stream through wrapped_receive into the

A teamless virtual key whose unified access_group_ids grant an
MCP-granting access group now sees and can call that server instead of
getting an empty list / 403. The key path previously read only the
legacy object_permission; this folds key.access_group_ids into the

A virtual key whose team has an MCP-granting access group attached
via /v1/access_group now sees that server through /v1/mcp/server (and

already resolves the key's unified access_group_ids; this adds the
symmetric resolution on the team side, mirroring the model-side
pattern in can_team_access_model — the group being on the team is
itself the gate, so no assigned_team_ids re-check is needed.

+14 d52fbfb458 Litellm oss staging 250526 (#28770)
* fix(mcp): handle OAuth IdP error responses in /callback (LIT-2750)

Per RFC 6749 section 4.1.2.1, when the IdP rejects an OAuth authorization
request it redirects back to the client with ?error=...&error_description=...
and no code. The MCP /callback handler declared code and state as required
query params, so FastAPI rejected such error responses with a 422 before
the handler ran -- stranding the MCP client waiting on the loopback.

This change:
- Makes code and state optional and accepts the RFC-defined error,
  error_description, and error_uri params.
- When state decodes to a trusted client redirect_uri, propagates the
  error params back to that URI with the client's original (un-wrapped)
  state preserved, so the client's OAuth library can surface the failure.
- When state is missing/undecryptable or the encoded redirect_uri is no
  longer trusted, renders a 400 HTML page with the (HTML-escaped) error
  details instead of leaking to an attacker-controlled redirect.
- Preserves the existing success path (code + state -> 302 to validated
  client redirect_uri with original state).

Fixes LIT-2750.

* test(mcp): regression tests for /callback handling IdP error responses (LIT-2750)

Adds a new test module covering the LIT-2750 fix: the MCP OAuth /callback
endpoint must accept IdP error responses (e.g. ?error=access_denied) per
RFC 6749 section 4.1.2.1 instead of returning a 422 because ``code`` is missing.

Coverage:
- IdP error with no state -> 400 HTML page surfacing the error.
- HTML escaping of user-controlled error / error_description fields.
- IdP error with a trusted (loopback) state -> 302 propagating
  error / error_description / original client state to the client.
- IdP error with an untrusted redirect_uri encoded in state -> 400 inline

* Fix Bedrock KB pass-through SigV4 headers and signed body

Coerce botocore HeadersDict to a dict for pass-through routes. When
forward_headers is true, drop request headers that collide case-insensitively
with signed headers so client Bearer auth does not shadow AWS SigV4.
Send prepped.body as raw content so the outbound payload matches the
signature after logging hooks mutate the parsed dict.

* Simplify pass-through raw body handling

Read the SigV4-signed bytes directly from request.state inside
pass_through_request instead of threading a custom_raw_body argument
through three functions. Helper methods are restored to their original
signatures, and the new branch lives in one place at each httpx call site.

* chore(tests): migrate Bedrock CI to AWS account 941277531214 (#28728)

* chore(tests): migrate Bedrock CI from AWS account 888602223428 to 941277531214

The original account (888602223428) was put under a security restriction by
AWS after a root access key leaked in a PR comment. While that account works
its way through the AWS Support unlock process, Bedrock-touching CI tests have
been migrated to a fresh account (941277531214).

Changes:
  - Replace 26 hardcoded references to 888602223428 with 941277531214 across
    8 files (provisioned-model ARNs, imported-model ARNs, AgentCore runtime
    ARNs, batch execution role ARN, and example proxy config).
  - The provisioned-model and imported-model ARNs are referenced only from
    mocked unit tests — no AWS resources to recreate.
  - The batch execution IAM role has been recreated in the new account with
    the same name and equivalent permissions.
  - The two AgentCore runtimes (hosted_agent_r9jvp-3ySZuRHjLC,
    hosted_agent_13sf6-cALnp38iZD) are being recreated in the new account
    under the same names — see tools/agentcore-deploy/ in a follow-up.

CircleCI env vars AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY / AWS_REGION_NAME
were updated separately via the CircleCI API to point at the new account.

Smoke-tested locally against the new account:
  aws bedrock-runtime converse --region us-west-2 \
    --model-id us.anthropic.claude-sonnet-4-5-20250929-v1:0 \
    --messages '[{"role":"user","content":[{"text":"ping"}]}]'
  → 200, model returned 'pong'

* chore(tests): refresh AgentCore ARN suffixes to match newly-deployed runtimes

The first migration commit replaced just the account ID, but AgentCore
auto-assigns a random 10-char suffix to every runtime on creation — we
can't reuse the original suffixes (`3ySZuRHjLC`, `cALnp38iZD`) in the
new account. Updated the AgentCore-runtime ARNs in the three files that
reference real runtime IDs (not the mock-based unit-test ARNs).

Deployed runtimes:
  arn:aws:bedrock-agentcore:us-west-2:941277531214:runtime/hosted_agent_r9jvp-Rq79QFC2fp
  arn:aws:bedrock-agentcore:us-west-2:941277531214:runtime/hosted_agent_13sf6-4046UzHSwy

Both runtimes are status=READY and pass a smoke invoke:
  $ aws bedrock-agentcore invoke-agent-runtime --agent-runtime-arn ... --payload '{"prompt":"ping"}'
  → 200, {"result": "echo: ping"}

The agent is a minimal echo (see /tmp/agentcore_deploy/agent.py for the
deploy artifacts). Tests that only verify the SDK wiring will pass; if any
test asserts on agent output content, swap the echo for the real agent.

* chore(tests): point Bedrock batch tests at new-account S3 bucket

The account migration (888602223428 -> 941277531214) was a flat
account-ID swap, which only rewrites ARNs that embed the account
number. S3 bucket names carry no account ID, so the live Bedrock
batch tests still uploaded to `litellm-proxy` — a bucket that lives
in the old account. S3 names are globally unique, and the old account
still holds that name, so it can't be recreated in the new account.

Rename to `litellm-proxy-941277531214` (account-ID suffix guarantees
global uniqueness). The bucket must be created in 941277531214 and the
batch execution role granted s3:GetObject/PutObject/ListBucket on it
before this job is run in CI.

* chore(tests): point live S3 logging test at new-account bucket

Same account-ID-free blind spot as the batch bucket: `load-testing-oct`
lives in the old account and its name can't be reused globally. The
`logging_testing` CI job is wired into the workflow and runs
test_basic_s3_logging, which uploads to this bucket with the CI env
creds, then lists and deletes objects — a live dependency.

Rename to `load-testing-oct-941277531214`. The bucket must exist in the
new account with the CI IAM principal granted
s3:PutObject/GetObject/ListBucket/DeleteObject before this job runs.

* chore(tests): repoint Bedrock guardrail IDs to new-account guardrails

The migration left guardrail IDs untouched (no account ID in them), so
all live guardrail tests failed with "guardrail identifier or version
does not exist" against 941277531214. Recreated both guardrails in the
new account and updated the hardcoded IDs:
  - wf0hkdb5x07f -> zgkmukebruil (PII mask: PHONE + CREDIT_DEBIT_CARD,
    with explicit inputAction=ANONYMIZE so masking applies to INPUT,
    which is the source litellm's moderation hook sends)
  - ff6ujrregl1q -> 4w3d1di3snt5 (blocks "coffee"; blocked message set
    to the exact string the tests assert on)

Updated test_bedrock_guardrails.py, otel_test_config.yaml, and the
guardrailConfig in test_bedrock_completion.py. Verified locally: the 5
previously-failing guardrail tests now pass.

* test(bedrock): migrate legacy models to current inference profiles

The new CI account (941277531214) cannot invoke legacy Bedrock models
(AWS gates them: "marked by provider as Legacy... not actively using in
the last 30 days"). Migrated the live-call tests:
  - anthropic.claude-3-sonnet-20240229    -> us.anthropic.claude-sonnet-4-5-20250929-v1:0
  - anthropic.claude-3-haiku-20240307     -> us.anthropic.claude-haiku-4-5-20251001-v1:0
Current Claude models on Bedrock require the us. inference-profile prefix
(bare on-demand ids are rejected).

cohere.command-r-plus has no working replacement (all Cohere is legacy-
gated in the new account): swapped to claude-haiku-4-5 in provider-
agnostic param lists. amazon.titan-image-generator skipped (no working
replacement). Mocked/transformation/cost tests that reference the legacy
strings are intentionally left unchanged. Verified live against the new
account.

* test(bedrock): repoint SageMaker + Knowledge Base to new-account resources

These referenced account-scoped resources by hardcoded id that only
existed in the old account, so the migration's account-ID swap missed
them. Recreated in 941277531214 and repointed:
  - SageMaker endpoint jumpstart-dft-hf-textgeneration1-mp-20240815-185614
    -> litellm-ci-textgen (gpt2 on a TGI container, ml.g5.xlarge)
  - Bedrock Knowledge Base T37J8R4WTM -> LCYXFBR2TU (OpenSearch Serverless
    vector store + titan-embed-text-v2, seeded with a LiteLLM doc)
Verified live: test_sagemaker.py (12 passed) and
test_bedrock_knowledgebase_hook.py (12 passed).

* test(reasoning_effort_grid): skip bedrock claude-opus-4-7 cells (not entitled on 941277531214)

claude-opus-4-7 is listed in the new Bedrock CI account's foundation
models but invoke is denied (AccessDeniedException: "not available for
this account"). Bedrock access to the flagship Opus requires an AWS
Sales request, not the self-serve model-access toggle, so it can't be
enabled inline with the rest of the account migration.

Add an optional `skip_reason` to ModelEntry and set it on the
bedrock-claude-opus-4-7 entry; the grid test honors it via pytest.skip.
Cell count (231) and route coverage are unchanged, so the structural
asserts still pass. Restore coverage by deleting the one skip_reason
line once access is granted.

* test(bedrock): swap/skip legacy-gated models unavailable on new CI account

The migrated AWS account (941277531214) cannot access several models that
the old account could, so the remaining red CI jobs were hitting real
Bedrock "Access denied / Legacy" and "account not authorized" errors:

- image_gen: skip both Nova Canvas test classes (amazon.nova-canvas-v1:0 is
  legacy-gated), matching the existing titan skip.
- batches: skip test_async_file_and_batch (Bedrock batch inference is not
  authorized on the new account; requires an AWS support case).
- litellm_overhead: swap legacy claude-3-5-haiku for the active
  us.anthropic.claude-haiku-4-5 inference profile.
- test_completion_claude_3_function_call: swap legacy claude-3-sonnet for the
  active us.anthropic.claude-sonnet-4-5 inference profile.

https://claude.ai/code/session_01Y7zgHYu9GX29YRwV4yiWAa

* test(bedrock): fix remaining e2e legacy-model + batch failures on new CI account

- e2e_openai_endpoints: skip test_bedrock_batches_api (Bedrock batch inference
  is not authorized on account 941277531214) and migrate the missed
  s3_bucket_name in oai_misc_config.yaml to litellm-proxy-941277531214.
- build_and_test: swap legacy bedrock claude-3-sonnet for the active
  us.anthropic.claude-sonnet-4-5 inference profile in the proxy structured
  output e2e test.

* test(bedrock): make opus-4-7 + batch cells fail loudly and mock image-gen (#28791)

Replace the silent skips added for the new CI account with noisier behavior:
- reasoning-effort grid: opus-4-7 cells now fail (when AWS creds are present)
  instead of skipping, so the missing entitlement stays visible in CI; they
  still skip when AWS creds are absent (local dev)
- Bedrock batch inference tests: drop the skip so they run and fail until
  batch access is granted
- Titan + Nova Canvas image-gen tests: mock the Bedrock HTTP call so the
  transform + cost-tracking path stays under test without live model access

https://claude.ai/code/session_01MT7SWDnXUjv6e6EPG7BDjT

* test(bedrock): use pytest.xfail for known-failing opus-4-7 cells

Replace pytest.fail with pytest.xfail when a model has a fail_reason,
so known-broken cells stay visible as XFAIL without keeping CI red.

Co-authored-by: Yassin Kortam <yassinkortam@Yassins-MacBook-Pro.local>

* chore(ci): merge dev branch (#28801)

* chore(proxy): route path-dependent call sites through get_request_route

Replace direct ``request.url.path`` reads in auth, ACL, routing, and
audit-log decisions with ``get_request_route(request)`` — the helper
already added in ``auth/auth_utils.py`` that returns the ASGI
``scope["path"]`` with ``root_path`` stripped. Starlette reconstructs
``url.path`` from the Host header; ``scope["path"]`` is uvicorn's
parse of the request line and matches what FastAPI dispatches on, so
it's the authoritative route for any decision that should agree with
the actual handler.

Sites:
- _experimental/mcp_server/auth/user_api_key_auth_mcp.py
- management_endpoints/mcp_management_endpoints.py
- vector_store_endpoints/utils.py
- pass_through_endpoints/pass_through_endpoints.py
- auth/route_checks.py
- litellm_pre_call_utils.py
- spend_tracking/spend_management_endpoints.py
- common_utils/http_parsing_utils.py
- management_helpers/utils.py
- health_endpoints/_health_endpoints.py

Adds regression tests in tests/proxy_unit_tests/test_proxy_routes.py
that construct a Request with scope["path"] set to a benign route and
the Host header crafted so url.path would resolve differently; each
site's decision is asserted against scope["path"].

* chore(proxy): make get_request_route imports lazy at call sites

Move the ``from litellm.proxy.auth.auth_utils import get_request_route``
imports added in the prior commit back to the function bodies that use
them. The module-level form participates in a long-standing import
cycle through ``auth_utils -> _types -> ...`` and was flagged by CodeQL
on the PR; the lazy form matches the pattern the proxy already uses
for ``user_api_key_auth`` and related helpers elsewhere in these files.

Also drop the ``RouteChecks._is_assistants_api_request`` delegation in
``_get_metadata_variable_name`` introduced in the prior commit — the
delegation pulled ``RouteChecks`` into the same cycle, and the call
site reuses the resolved route for its other branches, so inlining
the substring check is both cycle-free and avoids a redundant second
``get_request_route`` call.

Comment in test_proxy_routes.py acknowledges that the two MCP table
entries exercise ``get_request_route`` directly rather than the full
production handler (which needs ASGI scope + MCP state to invoke).

* fix(dashboard): drop dead useHealthReadiness import in navbar

The module was removed in #27896 (replaced by useHealthReadinessDetails),
but the import survived the rebase. The symbol is unused — only
useHealthReadinessDetails is consumed in the file. Removing the dead
import unblocks the UI TypeScript build.

* fix(dashboard): align CommunityEngagementButtons test with icon-only aria-labels

The component was refactored to an icon-only chip with aria-label='LiteLLM
on GitHub' (squash #27543), but the test still asserted /star us on
github/i. Update the query to match the rendered accessible name.

* refactor(dashboard): drop unused props from NavbarProps

The navbar refactor moved user identity + dark-mode state to internal
hooks (useAuthorized, useWorker), but the NavbarProps interface still
declared userID, userEmail, userRole, premiumUser, isDarkMode, and
toggleDarkMode as required, forcing every caller to thread them through.

Drop them from the interface and all four call sites (page.tsx,
(dashboard)/layout.tsx, public_model_hub.tsx, navbar.test.tsx). Also
shrinks the destructure in layout.tsx so the now-unused locals stop
being pulled out of useAuthorized().

* refactor(dashboard): use useSyncExternalStore for NotificationsBell dismiss flag

Reads/writes of the litellmHideAgentPlatformBanner key were done
directly inside NotificationsBell via a useEffect + useState pair.
Every other localStorage-backed flag in the dashboard (Disable
ShowPrompts, DisableBouncingIcon, DisableShowNewBadge,
DisableUsageIndicator, DisableBlogPosts) is wrapped in a
useSyncExternalStore hook over localStorageUtils so all mounted
components stay in sync.

Extract useHideAgentPlatformBanner to follow the same shape, swap
NotificationsBell to consume it, and add a regression test that
two sibling bells stay in sync without a remount when one is
dismissed.

* refactor: mask credential fields in proxy settings GET responses (#28682)

* refactor: mask credential fields in proxy settings GET responses

Brings SSO settings, cache settings, and the email/Slack alerting view in
/get/config/callbacks in line with the HashiCorp Vault config-override
pattern, so persisted credentials are not transported back to the UI in
plaintext.

* refactor: harden short-value masking and hoist alerting var constant

Closes two review observations:

- mask_sensitive_keys now replaces short values (below the visible
  prefix+suffix length) with an all-mask string instead of returning them
  unchanged, so a 1-7 character credential is no longer round-tripped
  verbatim.
- _ALERTING_SENSITIVE_VARS is moved out of get_config() to a module-level
  constant, matching the analogous _SSO_SENSITIVE_FIELDS and
  _CACHE_SENSITIVE_FIELDS in the SSO and cache endpoint files.

* feat(proxy): allow `llm_api_routes` virtual keys to list MCP servers (#28442)

* feat(proxy): allow llm_api_routes virtual keys to list MCP servers

Add a new `mcp_discovery_routes` group (GET /v1/mcp/server and GET
/v1/mcp/server/{server_id}) and include it in `llm_api_routes` so that
virtual keys configured with `allowed_routes=["llm_api_routes"]` can
discover the MCP servers they have access to. Previously these calls
failed with 'Virtual key is not allowed to call this route. Only allowed
to call routes: [llm_api_routes]'.

The GET handlers already sanitize the response for restricted virtual
keys via `_sanitize_mcp_server_list_for_virtual_key`, stripping
credential-bearing fields (url, headers, env). Write methods
(POST/PUT/DELETE) on the same paths remain gated by the existing
handler-level admin role checks.

The new discovery list is intentionally kept OUT of
`mcp_inference_routes`, so `is_llm_api_route()` still returns False
for these paths — this preserves the existing contract that
DISABLE_LLM_API_ENDPOINTS must not block the Admin UI from listing MCP
servers.

* refactor(proxy): make MCP discovery carve-out method-aware

Replace the `mcp_discovery_routes` group in `llm_api_routes` with a
method-aware special case inside `is_virtual_key_allowed_to_call_route`.
Virtual keys with allowed_routes=["llm_api_routes"] are now permitted
to call only GET /v1/mcp/server and GET /v1/mcp/server/{server_id} —
non-GET methods and multi-segment admin sub-paths fall through to the
existing 403. This keeps the general llm_api_routes list free of
management paths and avoids accidentally exposing POST/PUT/DELETE
writes through the route-check layer.

* fix(team): keep team_alias cache in sync on _cache_team_object writes (#28737)

* fix(team): keep team_alias cache in sync on _cache_team_object writes

_cache_team_object wrote only to the team_id:<id> cache key, but the
JWT auth path that uses team_alias_jwt_field reads from a separate
team_alias:<alias> key (get_team_object_by_alias caches under both
keys on miss, but reads only the alias-keyed one). After any
team-mutation endpoint (team_model_add, team_model_delete,
update_team, the two access-group writes) the team_id cache was
refreshed but the team_alias cache stayed stale until TTL — JWT
callers using team_alias_jwt_field kept seeing the pre-mutation
team for the full cache window.

Mirror the write under the alias key inside _cache_team_object so
every existing caller stays in sync without further changes. Skip
the alias write when team_alias is None/empty so we don't collide
across alias-less teams.

Surfaced testing the LIT-3244 cherry-pick on patch/1.86.0: the
LIT-3244 fix correctly invalidated the team_id cache but the
customer's JWT used team_alias_jwt_field, so they kept hitting the
stale alias-keyed entry.

* fix(team): delete (not overwrite) team_alias cache on _cache_team_object

The prior shape of this PR wrote both team_id:<id> AND team_alias:<alias>
from _cache_team_object. team_alias is NOT unique in the schema
(no @unique on LiteLLM_TeamTable.team_alias), and get_team_object_by_alias
enforces uniqueness on its own DB-fetch path (len(teams) > 1 raises).
Writing the alias-keyed cache from the generic refresh path bypassed
that check: a team admin renaming their team to collide with another
team's alias could silently overwrite the cached team for JWT-by-alias
auth, swapping the resolved team under that alias for the cache window.

Switch the alias-keyed operation from a write to a delete (mirroring
the dual-cache delete pattern in _delete_cache_key_object). After every
team write, the next JWT-by-alias reader cache-misses and falls through
to get_team_object_by_alias, which (a) re-fetches the fresh team from
DB, closing the LIT-3244 staleness gap that motivated this PR, and
(b) enforces alias uniqueness before populating either cache key.

team_id:<id> writes are unchanged — team_id is the table PK and is
guaranteed unique.

Surfaced in veria-ai review on #28739.

* fix(managed-files): anchor model_id regex so it doesn't match llm_output_file_model_id

extract_model_id_from_unified_id used `re.search(r"model_id,([^;]+)", ...)`
which substring-matches the `model_id,` inside the file-ID encoding's
`llm_output_file_model_id,<deployment_uuid>` field. parse_unified_id
then fed that deployment UUID back into the auth path as a model
candidate via _extract_models_from_managed_resource_id, and every
team-BYOK file attach 403'd with:

    team not allowed to access model. This team can only access
    models=['openai/*']. Tried to access <deployment-uuid>

The team's models list correctly contains the public name (`openai/*`)
that target_model_names matches, but the bogus UUID candidate fails
the wildcard check first.

Anchor the regex to a field boundary (`(?:^|;)model_id,`) so it
matches the legitimate top-level `model_id,<value>` field on
vector_store unified IDs and skips substring matches inside other
fields. File-IDs (which have no top-level `model_id` field) now
return None and contribute no spurious UUID candidate.

Surfaced reproducing LIT-3244 on patch/1.86.0 with the customer's
exact flow: team with openai/* BYOK deployment, JWT-scoped user,
POST /v1/vector_stores/{id}/files attaching a file uploaded with
target_model_names=openai/gpt-4o.

* test(proxy): add harness for proxy_server.py behavior-pinning (#28827)

* test(proxy): add harness for proxy_server.py behavior-pinning

Creates tests/test_litellm/proxy/proxy_server/ with:
- conftest.py: 11 shared fixtures (app, client, mock_prisma, auth_as,
  mock_router with parametrized response builders, normalize, etc.)
- _coverage_check.py: per-PR coverage gate (line + branch) against a
  baseline, self-selects target by inspecting which placeholder files
  have been filled
- _pin_check.py: AST-based gate that verifies every pin-list item has
  >=1 happy + >=1 error test with a real assertion (no status-only)
- test_harness_smoke.py: 19 smoke tests covering every fixture +
  both scripts end-to-end
- 26 placeholder test files (one docstring each) reserved for
  follow-up PRs per the directory ownership in the Notion plan
- .coverage_baseline pinned at 0% so future PRs measure deltas
  against new-tests-only and aren't entangled with the broader
  scattered test suite

Adds a dedicated proxy-server job to test-unit-proxy-endpoints.yml
so this directory's runtime + coverage are tracked independently.

Plan: https://www.notion.so/36c43b8acdab81ee845fd5365128a2fc

* ci(proxy-endpoints): allow workflow_dispatch

Lets the workflow be triggered manually on a branch via
`gh workflow run`, which is needed for the verify-first
flow on workflow changes before opening a PR.

* test(proxy): address review feedback on proxy_server harness

- conftest.py: anchor sys.path insert to __file__ (Path(__file__).resolve().parents[4])
  instead of CWD-relative os.path.abspath("../../../../") which resolved
  to the wrong directory when pytest is launched from the repo root.
- _coverage_check.py: actually read .coverage_baseline and use it as
  the floor (line_min = max(target, baseline)). Closes the gap between
  the PR description's "delta semantics" and what the script was doing.
  With baseline=0.0 today this is a no-op; future PRs that update the
  baseline cause regressions (test deletions etc.) to trip the gate
  even if the static PR target is still met.
- _pin_check.py: drop unreachable startswith("_") guard
  (test_*.py glob never yields underscore-prefixed names) and read
  each test file once instead of twice.

* feat(openai): apply regional-processing cost uplift for EU/US data residency (#28626)

* feat(openai): apply regional-processing cost uplift for EU/US data residency

OpenAI charges a 10% uplift on the latest GPT models when requests are
served from a regionalized hostname (eu./us.api.openai.com).  Infer the
region from `api_base`, expose it on `kwargs["litellm_params"]["data_residency"]`,
and multiply the computed cost by a per-model
`regional_processing_uplift_multiplier_<region>` field.

https://claude.ai/code/session_012ebH44s7ohYxjoix5CXzTW

* test: allow regional_processing_uplift_multiplier_{eu,us} in model_prices schema

* fix(cost): tighten data_residency inference and restore model_cost in tests

- Only infer OpenAI data_residency when custom_llm_provider == "openai";
  drop the implicit None fallback so non-OpenAI callers can't accidentally
  pick up a regional tag from a stray OpenAI hostname.
- _local_model_cost_map fixture now snapshots and restores
  litellm.model_cost and LITELLM_LOCAL_MODEL_COST_MAP so tests don't leak
  state across the session.

* refactor(openai): move data_residency helper under llms/openai

* fix: thread data_residency through realtime stream cost calculation

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(cost): thread data_residency through batch_cost_calculator

Apply the OpenAI regional-processing uplift multiplier to retrieve_batch
cost paths so Batch API requests served via eu./us.api.openai.com are
priced at the same uplifted token rates as completions/transcriptions.

* refactor(openai): encapsulate provider check inside infer_openai_data_residency

Move the custom_llm_provider == "openai" guard from get_litellm_params
into the helper itself so the core utility no longer carries
provider-specific dispatch logic. Callers pass through the provider
unconditionally; the helper returns None for any non-OpenAI provider.

* fix(responses): thread data_residency through Responses logging params

The Responses API paths build their logging litellm_params dict after
provider resolution but did not include data_residency, so cost calc
saw None even when the effective api_base was a regional OpenAI host.

* chore(github_copilot): refresh model catalog from upstream /models API (#28055)

Aligns the github_copilot catalog with values returned by Copilot's
public /models endpoint (capabilities.limits + capabilities.supports +
model.supported_endpoints).

- Adds 10 new model entries: claude-opus-4.7, claude-sonnet-4.6,
  gemini-3-flash-preview, gemini-3.1-pro-preview, gpt-4-0125-preview,
  gpt-5.2-codex, gpt-5.4, gpt-5.4-mini, gpt-5.5, oswe-vscode-prime.
- Updates max_input_tokens for existing entries to reflect each
  model's true context window (e.g. gpt-4o-mini 64000 -> 128000,
  gpt-5-mini 128000 -> 264000, gpt-5.3-codex 128000 -> 400000,
  claude-haiku-4.5 128000 -> 200000).
- Adds supports_reasoning, supports_response_schema,
  supports_function_calling, supports_parallel_function_calling,
  supports_vision based on capabilities.supports.
- Declares supported_endpoints for entries missing it
  (e.g. gpt-3.5-turbo, gpt-4o, embeddings).
- For responses-only models (gpt-5.2-codex, gpt-5.4, gpt-5.4-mini,
  gpt-5.5), sets mode to 'responses'.
- gpt-41-copilot.mode changes from 'completion' to 'chat' because
  Copilot reports capabilities.type = 'chat'. Revertible on request.

Pricing fields and other manually-curated values are preserved.

* feat(datadog): emit litellm.overhead.latency as a standalone Datadog metric (#28831)

Adds a new `litellm.overhead.latency` gauge metric to `DatadogMetricsLogger`
(the `/api/v2/series` path). The value is sourced from
`hidden_params["litellm_overhead_time_ms"]` already computed in
`ResponseMetadata` and exposed in `StandardLoggingPayload`.

Matches the Prometheus integration which exposes the same value via
`litellm_overhead_latency_metric`. Emitted in seconds (ms ÷ 1000) for
consistency with the other latency series.

* feat(arize): route Phoenix traces via per-project TracerProviders (#28876)

Use LRU-cached TracerProviders with project-scoped OTEL Resources so team/key
metadata routes traces correctly. On the proxy, project selection is limited to
server-controlled user_api_key_auth_metadata; client metadata fields stay banned.

* fix(arize_phoenix): skip _emit_semantic_logs on failure path

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(arize_phoenix): skip raw request logging and metrics on failure path

Restores pre-refactor behavior: _handle_failure no longer emits raw-request
sub-spans or records OTEL metrics, matching the original _handle_failure
that did not call these helpers.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(security): close two medium telemetry trust-boundary issues

Issue 1 (arize_phoenix.py — caller-controlled telemetry routing):
- _is_proxy_request no longer detects proxy mode by checking
  user_api_key_auth_metadata in request metadata.  That field is
  user-supplied, so an authenticated caller could fake proxy-mode
  detection and have _project_from_metadata_dict read their own dict
  for project selection, routing telemetry to arbitrary Arize/Phoenix
  projects.  Proxy mode is now determined solely by the server-set
  proxy_server_request field in litellm_params.
- auth_utils.py adds user_api_key_auth_metadata to the banned request
  body params list so the proxy rejects any attempt to supply the field
  at the HTTP layer.  The field is server-reserved: it is written
  exclusively by add_user_api_key_auth_to_request_metadata from the
  authenticated key's database record after the ban check runs.

Issue 2 (management_helpers/utils.py — API key in OTEL span):
- _emit_management_endpoint_otel_span stripped plaintext credential
  fields (key, token, api_key, secret, …) from the response dict before
  passing it to the OTEL success hook.  dict(result) on a Pydantic
  GenerateKeyResponse includes the freshly-generated key field, which
  would previously be written as a span attribute to every configured
  OTEL collector/backend.

ef36e89638 feat(mcp): Add tool call and tool list support via UI for Oauth mcps (#28454)
* feat(mcp): cache OAuth token client-side so Tools tab loads without re-auth

After a user creates an OAuth MCP server and completes the authorization
flow, the resulting access token is now stored in sessionStorage keyed by
server_id.  The MCP Tools tab reads this cached token and includes it as
an MCP auth header when listing and invoking tools, so the user never sees
an empty tool list.  When the session ends (tab close / new browser) an
Authorize button re-triggers the flow without leaving the Tools screen.

Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

* fix(ui/mcp): surface listMCPTools 401 errors so auth gate reappears

listMCPTools previously swallowed all errors (including HTTP 401) by
returning a synthetic { tools: [], error: 'network_error', ... } payload.
That made the useQuery retry-on-401 guard and mcpToolsError dead code,
so expired OAuth tokens never re-triggered the auth gate.

- Throw an enhanced Error with .status attached on non-2xx responses
  (still preserves the legacy shape for true network failures so the
  caller can render a generic message without crashing).
- Clear the cached OAuth session token when the tools query fails with
  401, mirroring callMCPTool's onError handler so the Authorize button
  is shown again.
- Surface mcpToolsError in the existing error banner.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp-tools): stable onSuccess + reuse parsed flow state

- Pass stable setOauthToken setter directly as onSuccess to avoid
  recreating useToolsOAuthFlow's resumeOAuthFlow on every render.
- Reuse the already-parsed FLOW_STATE_KEY value (peeked) instead of
  re-reading and re-parsing sessionStorage in resumeOAuthFlow.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(ui/mcp): restore listMCPTools never-throws contract

The previous fix made listMCPTools throw on HTTP errors while still
returning a synthetic object on network errors. This inconsistent
contract broke existing callers (MCPToolPermissions, MCPAppsPanel,
MCPConnectPicker) which inspect result.error / result.message and
expect the function to never throw.

- Return a normalized { tools: [], error, message, status, ... }
  object on HTTP errors (instead of throwing) so all callers see a
  consistent shape and the user-visible error text from
  result.message is preserved.
- Convert the returned error object into a thrown Error inside the
  one caller that needs it — the useQuery in mcp_tools.tsx — so the
  401 retry/onError handlers still trigger and clear the cached
  OAuth token.

* fix greptile

* fix(mcp): align OAuth header alias lookup with dashboard sanitization

Backend auth header resolution now matches x-mcp-{alias} keys produced by
the dashboard sanitizer, and the Tools tab re-syncs OAuth tokens when
serverId changes.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp): widen auth header lookup types for list_tools

Accept legacy str | dict server auth maps and annotate list_tools
server_auth_header as Union[str, dict] for mypy.

* refactor(ui): extract shared buildCallbackUrl/clearStorage for MCP OAuth hooks

Hoist the duplicate buildCallbackUrl and clearStorage helpers out of
useToolsOAuthFlow and useUserMcpOAuthFlow into a new shared module
src/hooks/mcpOAuthUtils.ts so the two hooks cannot drift if the URL
construction or storage cleanup logic needs to change.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(ui): don't gate M2M OAuth MCP servers behind interactive authorize

M2M (client_credentials) OAuth servers share auth_type="oauth2" with
interactive PKCE servers, but the backend fetches their token internally
and they typically lack a user authorization endpoint. Gating tool
listing on them rendered an Authorize button that would fail or redirect
incorrectly. Detect M2M via the presence of token_url (matching the
existing heuristic in mcp_server_edit.tsx) and skip the auth gate.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(ui/mcp): return error shape when listMCPTools JSON parse fails

Restore the never-throws contract when response.json() fails on a 2xx

* fix(mcp-oauth): improve redirect_uri errors without leaking internal config

Use NoReturn on _oauth_invalid_request, structured errors for BYOK loopback
validation, and refactor validate_trusted_redirect_uri to satisfy PLR0915.
Keep PROXY_BASE_URL and raw proxy_base_url in server logs only, not in the
HTTP 400 body returned to unauthenticated callers.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp-oauth): stop leaking internal proxy origin in redirect_uri 400 body

The trusted-redirect-uri rejection helper included the proxy's
resolved scheme/host/port (e.g. http://litellm-internal:4000) in both
the error_description and as a top-level proxy_origin field. Since
the OAuth /authorize endpoint is unauthenticated, any caller could
probe with a crafted redirect_uri and enumerate the internal network
topology behind a reverse proxy.

Keep full diagnostic detail in the server-side warning log
(including the computed proxy base) but omit proxy-side values from
the HTTP 400 body. Also drop the duplicated origin computation in
_raise_trusted_redirect_uri_rejected now that those values are no
longer needed by the response.

718c4637a8 feat(mcp): allow native MCP OAuth support for cursor (#28327)
* feat(mcp): allow native MCP OAuth redirect URIs (cursor://)

Discoverable OAuth /authorize rejected cursor:// callbacks because
validate_trusted_redirect_uri only accepted http/https. Add an
allowlisted native path with a built-in Cursor default and optional
MCP_TRUSTED_NATIVE_REDIRECT_URIS env for other clients.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp): address Greptile native redirect URI review

Lowercase paths in normalizer so env allowlist entries match case-
insensitively. Tighten wildcard prefix matching to reject sibling
paths (e.g. callback-2) unless the prefix ends with /.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp): reject query params on native OAuth redirect URIs

Greptile: normalization stripped query strings before allowlist compare,
so cursor://.../callback?injected=... could pass validation. Reject any
native redirect_uri with a query component (same as fragments).

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(model_cost_map): add mistral/ministral-8b-2512 entry

Mistral rotated the 'mistral/mistral-tiny' alias to return
'ministral-8b-2512' as the response model, which is not in the cost map.
This caused test_completion_mistral_api and
test_completion_mistral_api_modified_input to fail in
completion_cost lookup. Add the entry mirroring the existing
openrouter/mistralai/ministral-8b-2512 pricing.

* fix(mcp): lowercase default native redirect URIs

Make _parse_trusted_native_redirect_uris apply the same lowercasing
to built-in defaults as it does to env-var entries.

* fix(tests): backfill local model_cost into remote-fetched map

litellm.model_cost is loaded at import time from the URL pinned to main,
so pricing entries that exist only in this branch (e.g.
mistral/ministral-8b-2512, freshly added because Mistral now returns this
id from mistral-tiny) are absent at test time and completion_cost lookups
raise. Backfill the in-tree backup so cassette-driven cost calculations
resolve against the entries that ship with the branch under test.

Fixes the local_testing_part1 failures on test_completion_mistral_api and
test_completion_mistral_api_modified_input.

68efe6970c fix(mcp): JWT on tools/list and REST tools/call server resolution (#28227)
* fix(mcp): JWT on tools/list, REST server_id resolution, tool_server_mismatch

Sign outbound MCP JWTs for list_mcp_tools and inject headers on the tools/list
path. Resolve server_id on /mcp-rest/tools/call and return 403 tool_server_mismatch
when the tool does not belong to the requested server. Default missing arguments to {}.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp): restrict list JWTs to mcp:tools/list and default REST arguments to {}

- List-only JWTs (call_type=list_mcp_tools) no longer carry the broad
  mcp:tools/call scope. _build_scope() now emits only mcp:tools/list
  when no tool name is provided, mirroring the existing least-privilege
  rule that tool-call JWTs omit mcp:tools/list.
- REST /tools/call now defaults a missing 'arguments' field to {} so
  execute_mcp_tool() and downstream **arguments / .keys() calls don't
  receive None and crash with TypeError/AttributeError.

* fix(mcp): match alias/server_name in _resolve_mcp_server_for_tool_call

The registry lookup in _resolve_mcp_server_for_tool_call previously only
compared candidate.name against the provided server_name, but tool name
prefixes can be derived from a server's alias or server_name (see
get_server_prefix). When the tool→server mapping is empty/stale (cold
start, dynamic tools), the lookup would fail for alias-configured
servers even though get_mcp_server_by_name (used by the REST path)
matches alias, server_name, and name.

Match the same priority of identifiers in both the registry pass and
the unprefixed fallback so the MCP protocol call_tool path is
consistent with the REST path.

* fix(mcp): reuse proxy_logging DualCache in inject_mcp_jwt_headers_for_upstream

Instead of allocating a fresh DualCache() on every tools/list invocation,
prefer the shared proxy_logging_obj.internal_usage_cache.dual_cache when
available. The cache argument is currently unused by MCPJWTSigner, but
sharing the proxy's cache avoids per-call allocation overhead and matches
the cache identity used elsewhere in the proxy hook plumbing — so any
future per-request state stored in cache will survive across list calls.

* fix(test): accept user_api_key_auth kwarg in list_tools mocks

The proxy-infra job was failing on four TestMCPServerManager tests because
the mock_get_tools_from_server stubs did not accept the new
user_api_key_auth keyword argument that list_tools now forwards to
_get_tools_from_server. Add the kwarg to each stub so list_tools can call
through cleanly.

* fix(mcp): skip JWT injection when per-user mcp_auth_header is set

MCPClient._get_auth_headers() applies extra_headers AFTER writing
Authorization from auth_value, so an injected JWT silently overwrites
the user's per-server OAuth token. Guard the JWT signer with
'not mcp_auth_header' so per-user OAuth (and any dict-form per-user
auth) takes precedence, mirroring the existing static_headers guard.

Adds a regression test that the signer's inject helper is not called
when mcp_auth_header is supplied.

* fix(mcp): skip JWT injection when extra_headers already has Authorization

When a server uses per-user OAuth tokens, the resolved token is passed
into _get_tools_from_server via extra_headers. The JWT injection guard
only checked mcp_auth_header and the server's static headers, so the
signer would silently overwrite the user's OAuth Authorization header.

Add a check for an existing Authorization entry in extra_headers so
caller-supplied per-user OAuth tokens take precedence over JWT signing.

* test(mcp): cover JWT signer + tool-call resolution branches

Adds unit tests for the new MCPServerManager helpers (_resolve_mcp_server_for_tool_call,
_resolve_oauth2_headers_for_tool_call) and the new MCPJWTSigner paths
(_build_scope call_type branches and inject_mcp_jwt_headers_for_upstream).
Brings patch coverage above the auto target without changing behavior.

* fix(mcp): retry tool-server lookup with prefixed name in REST mismatch check

When the REST /mcp-rest/tools/call path sends a raw tool name plus
requested_server_id, _get_mcp_server_from_tool_name(name) can return
None if the mapping only stores the prefixed form. That bypassed the
tool_server_mismatch 403 guard and let the call fall through to
trusting requested_server.

Retry the lookup with every known prefix of the requested server so
the mismatch check fires whenever the tool is actually registered.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): always reject unknown tools in server-name fallback

Defense-in-depth: _resolve_mcp_server_for_tool_call previously skipped
the unknown-tool check whenever the per-server mapping had no entries
yet (cold start, OAuth2 lazy listing, or upstream listing failure),
allowing arbitrary tool names to reach upstream servers.

Tighten the check so the server-name fallback always rejects tool
names not present in the mapping. Callers must call list_tools first
(standard MCP flow) before tools/call can resolve. Removes the
now-unused _mapping_has_tools_for_server helper and adds an
explicit empty-mapping rejection test alongside the existing
populated-mapping rejection test.

1b0ae3af83 fix(mcp-oauth): PROXY_BASE_URL escape hatch + diagnostic logging for {"detail":"invalid_request"} (#28086)
* fix(mcp-oauth): add PROXY_BASE_URL escape hatch + diagnostic logging for invalid_request

Customers hitting "{"detail":"invalid_request"}" on the MCP /authorize
endpoint had no way to recover when their ingress mangles X-Forwarded-*
headers (the same-origin check in validate_trusted_redirect_uri compares
the browser-supplied redirect_uri against get_request_base_url, which is
reconstructed from those headers).

Two contained changes:

  1. get_request_base_url now honours PROXY_BASE_URL as the canonical
     public origin when set, bypassing the X-Forwarded-* trust gate
     entirely. Operators who know their public URL can set it once
     instead of debugging ingress header rewrites.

  2. The rejection path in validate_trusted_redirect_uri emits a WARN
     log carrying the redirect_uri, computed proxy base, and the
     X-Forwarded-* / Host headers seen. A bare 400 was undiagnosable;
     this turns it into a one-line root-cause.

* test(mcp-oauth): capture warnings from correct logger ("LiteLLM")

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp-oauth): reject malformed PROXY_BASE_URL with one-shot diagnostic

A scheme-less PROXY_BASE_URL (e.g. "litellm.example.com" instead of
"https://litellm.example.com") would sail through urlparse with empty
scheme + netloc, silently breaking every same-origin compare in
validate_trusted_redirect_uri and leaving the operator staring at the
same opaque 400 the env var was meant to fix.

Validate it once at read time: only honour values that parse as
http(s) URLs with a non-empty netloc; otherwise log a one-shot WARN
naming the bad value and fall through to the request-derived origin
so the proxy still serves traffic.

* fix(mcp/oauth): normalize PROXY_BASE_URL to strip query/fragment

Match the X-Forwarded-* path's normalization so a configured
PROXY_BASE_URL containing a query string or fragment does not break
downstream f-string concatenation like f"{base_url}/callback".

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* refactor(mcp-oauth): drop non-essential comments from PROXY_BASE_URL changes

Strip narrative comments and verbose docstrings added in this PR; the
code is intuitive enough on its own and the log messages already carry
their own diagnostic context. Pre-existing comments are left untouched.

18f77ff7bc feat(mcp): add delegate_auth_to_upstream flag for PKCE passthrough (#27834)
* feat(mcp): add delegate_auth_to_upstream flag for PKCE passthrough

Adds an opt-in per-server flag that lets clients (e.g. VS Code) complete
PKCE directly with an upstream OAuth2 MCP server, instead of LiteLLM
double-gating with its own API-key/SSO check. Only honored when
auth_type=oauth2 and the operator explicitly sets the flag; mixed-target
or non-oauth2 requests fail closed.

- Adds the field to Pydantic models, Prisma schema, and a migration
- New MCPRequestHandler._target_servers_delegate_auth_to_upstream gate
  that runs only when no x-litellm-api-key is present, so authenticated
  users still get user_id resolution + stored-credential lookup
- Anonymous callers now see delegate servers in get_allowed_mcp_servers
  (scoped to delegate servers only; the upstream still enforces auth)
- mcp_management_endpoints: allow anonymous /authorize and /token for
  delegate servers so VS Code can complete PKCE without a LiteLLM session
- UI toggle (shown only for oauth2) + payload/view wiring
- Tests covering: oauth2 on/off, non-oauth2 with flag, mixed targets,
  no resolvable target, explicit key precedence, and 401 emission

* Enforce oauth2 for delegated MCP auth bypass

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): close secondary Authorization bypass for delegate servers

The delegate-auth bypass gated only on the primary `x-litellm-api-key`
header, so a LiteLLM key sent via `Authorization: Bearer sk-...` (the
secondary header) was silently dropped — skipping spend tracking and
rate limiting. Gate on the resolved litellm_api_key (which considers
both headers) so the bypass fires only when neither is present.

Also update the existing "Authorization header present" test to reflect
that an upstream OAuth token now flows through the existing oauth2
fallback (LiteLLM auth attempt → fail → anonymous), not via the
delegate branch.

* Avoid duplicate MCP OAuth credential lookup

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): block delegate bypass for M2M and internal-only servers

Two security issues flagged in code review:

1. High – client_credentials (M2M) servers must not be delegatable:
   LiteLLM auto-fetches the upstream token using stored credentials, so
   allowing anonymous bypass would let any external caller invoke tools
   authenticated as LiteLLM's service account.
   Fix: check `server.has_client_credentials` in
   `_target_servers_delegate_auth_to_upstream`, the anonymous
   allow-list in `get_allowed_mcp_servers`, and `_mcp_oauth_user_api_key_auth`.

2. Medium – internal-only servers exposed to public internet:
   The anonymous delegate allow-list was not filtering by
   `available_on_public_internet`, so external callers with an upstream
   OAuth token could invoke tools on servers marked internal-only.
   Fix: add `available_on_public_internet` guard to the anonymous
   delegate server list in `get_allowed_mcp_servers`.

Tests added for both cases.

* Require public MCP delegate auth servers

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): align delegate auth path parsing with downstream routing

`_extract_target_server_names_from_path` used a naive segments-based
split while `server.py::_get_mcp_servers_in_path` uses a regex that
allows server names with one embedded slash and comma-separated lists.
With the old parser, a request to `/mcp/<delegated>/<garbage>` was
parsed as targeting `<delegated>` by the auth gate (bypassing LiteLLM
auth) while the routing layer parsed it as `<delegated>/<garbage>` —
when that name did not resolve, the request fell back to the anonymous
allow-list, which can include `allow_all_keys` servers that normally
require a LiteLLM key.

Replace the parser with the same regex logic as
`_get_mcp_servers_in_path` so auth gating sees the exact target name(s)
downstream routing sees. Add regression tests covering parser parity
and the specific extra-path-segment bypass attempt.

* fix(mcp): close header/path TOCTOU in MCP delegate auth gate

`_target_servers_delegate_auth_to_upstream` and
`_target_servers_use_oauth2` trusted the `x-mcp-servers` header when
present, but `server.py::extract_mcp_auth_context` overrides that
header with the path-derived list for `/mcp/...` routes. An attacker
could set `x-mcp-servers: <delegated>` while pointing the URL path at
a non-delegate server, flipping the auth gate without changing the
target downstream routing actually uses.

Extract a shared `_resolve_target_server_names` helper that mirrors
the downstream override (path-derived names for `/mcp/...` routes,
header value otherwise). Add regression tests covering the TOCTOU
attempt and the helper's path-vs-header precedence.

* Fix delegated MCP OAuth test mock

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): drop unreachable /{server}/mcp branch in auth path parser

`_extract_target_server_names_from_path` also matched the
``/{server_name}/mcp`` form, but the downstream parser
``_get_mcp_servers_in_path`` only handles ``/mcp/...`` — and
``dynamic_mcp_route`` in ``proxy_server`` rewrites ``/{name}/mcp``
to ``/mcp/{name}`` on the scope before the MCP handler runs. Parsing
the un-rewritten form on the auth side was therefore unreachable in
production, and contradicted the docstring's claim of mirroring the
downstream parser — exactly the kind of mismatch that risks a future
header/path TOCTOU if any new entry point skips the rewrite.

Drop the branch; the canonical ``/mcp/...`` path matches both
parsers. Update the regression test to assert the new behavior.

* Fix MCP path auth target resolution

* fix(mcp): require auth for refresh_token grants on delegate-auth servers

`_mcp_oauth_user_api_key_auth` gates the unauthenticated PKCE flow for
``delegate_auth_to_upstream`` servers, but the bypass applied to BOTH
``/authorize`` and ``/token`` regardless of grant type. ``mcp_token``
accepts ``grant_type=refresh_token`` as well as ``authorization_code``,
and ``exchange_token_with_server`` attaches the server's stored
``client_secret`` to whatever is forwarded upstream. An unauthenticated
caller holding a refresh token issued to that OAuth client could mint
fresh upstream access tokens through LiteLLM.

Limit the anonymous bypass on ``/token`` to ``grant_type=authorization_code``
(the only grant PKCE actually protects via ``code_verifier``); fall
through to normal LiteLLM auth for ``refresh_token`` and any other grant.
``/authorize`` continues to allow anonymous PKCE redirects.

https://claude.ai/code/session_01SjyPmwfmrq8fveFgw9iHW9

* fix(ui): clear delegate_auth_to_upstream when switching off oauth2

The ``delegate_auth_to_upstream`` form field is rendered inside an
``isOAuth2 && (...)`` conditional, so the Form.Item unmounts when the
user changes ``auth_type`` away from ``oauth2``. The follow-up
``form.setFieldValue("delegate_auth_to_upstream", false)`` runs after
the field has already deregistered, so ``onFinish`` receives
``undefined`` and the fallback ``?? mcpServer.delegate_auth_to_upstream``
preserved the old ``true``. The flag then persisted in the database for
a non-oauth2 server and silently re-activated if ``auth_type`` was later
switched back to ``oauth2``.

In the edit payload, force the flag to ``false`` whenever
``auth_type !== oauth2``; only trust the form value (and the existing
DB fallback) when the server is actually oauth2. Backend defense-in-depth
already ignores the flag for non-oauth2 servers, but the DB state should
stay clean too.

466f06df6d fix(mcp): surface upstream 401 for token-forwarding MCP servers (#27847)
* fix(mcp): surface upstream 401 for token-forwarding MCP servers

For MCP servers configured with extra_headers: [Authorization], the gateway
forwards the client token directly to the upstream. When that token is rejected
(expired or invalid) the upstream returns 401, but the MCP SDK starts the SSE
stream with 200 OK before calling handlers, so the 401 can't be returned
mid-stream.

Fix: add a pre-flight httpx probe in handle_streamable_http_mcp — before the
SDK opens the session — so the gateway can still return HTTP 401 with
WWW-Authenticate: Bearer authorization_uri=<gateway-discovery-url> when the
upstream rejects the token. The probe fails-open (returns 200) on network
errors so a transient hiccup does not block valid requests.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp): parallelize pre-flight auth probes and use HEAD to avoid side effects

- Extract forwarded_auth outside the pass-through server loop (was called N times for the same scope value)
- Gather all upstream auth probes concurrently with asyncio.gather instead of sequentially; eliminates N×5 s worst-case latency
- Switch probe from POST+initialize JSON-RPC body to HEAD request; HEAD carries the Authorization header so the upstream rejects invalid tokens with 401 but never allocates a session or writes an audit entry

* fix(mcp): use get_async_httpx_client in _probe_upstream_auth

Replaces bare httpx.AsyncClient with the project-standard
get_async_httpx_client(httpxSpecialProvider.MCP) to satisfy the

per-request overhead of creating a new client on every probe call.

* refactor(mcp): extract pre-flight probe into _check_passthrough_upstream_auth

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp): gate pre-flight probes on authorized server set to prevent bypass

_check_passthrough_upstream_auth was resolving user-supplied server names
directly before authorization ran, letting any permitted LiteLLM key
trigger an upstream HEAD probe to a server it was not allowed to use.

Changes:
- Call _get_allowed_mcp_servers inside the helper so only servers the
  caller's key is authorized for are probed.
- Move the call site to after toolset scoping so the auth context is
  fully resolved before the probe list is built.
- Thread user_api_key_auth into the helper signature (replaces the raw
  mcp_servers name list).

_prepare_mcp_server_headers skips caller Authorization when the server
uses OAuth client-credentials (M2M), but the pre-flight probe was still
selecting those servers and forwarding the caller's raw token in the HEAD
request. Exclude servers with has_client_credentials from the probe list
to match the actual downstream header-preparation logic.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp): propagate upstream 403 as 403, not 401 with WWW-Authenticate

Per RFC 9110, 401 means "go get new credentials." Mapping an upstream 403
to a gateway 401 causes OAuth clients to restart the authorization flow,
obtain a fresh token with identical scopes, hit 403 again, and loop
indefinitely.

401 from upstream → gateway 401 + WWW-Authenticate (re-authorize)
403 from upstream → gateway 403 (no WWW-Authenticate hint)

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp): skip auth probe when Authorization may be the LiteLLM proxy key

The pre-flight upstream probe must not forward the caller's Authorization
header when it could itself be the LiteLLM proxy API key. Restrict the
probe to requests that supply x-litellm-api-key explicitly — only then is
the Authorization header unambiguously the upstream OAuth token the
caller wants forwarded.

* Fix MCP ASGI HTTPException propagation

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): use public AsyncHTTPHandler.post() in auth probe

Use AsyncHTTPHandler.post() and catch httpx.HTTPStatusError explicitly so
the 401/403 we want to surface is not silently swallowed by the broad
fail-open except Exception block. Avoids reaching into the handler's
private client attribute, which would silently regress to fail-open if
AsyncHTTPHandler is ever refactored.

* Fix MCP auth probe tests

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* test(mcp): add coverage for httpx.HTTPStatusError path in auth probe

AsyncHTTPHandler.post() calls raise_for_status() internally, so a real
upstream 401/403 lands as httpx.HTTPStatusError. Add a test that exercises
that specific exception path so a regression that swallows the error in
the broad fail-open except Exception would be caught.

Tool names with characters like `/` or `.` (commonly produced by the
OpenAPI -> MCP generator from `operationId`s such as
`actions/download-job-logs-for-workflow-run`) caused Anthropic to reject
requests with `tools.N.custom.name: String should match pattern
'^[a-zA-Z0-9_-]{1,128}$'`.

Two layers of fix:

1. Anthropic transformation: build a per-request forward map (original ->
   sanitized, disambiguated by suffix on collisions) and a reverse map
   (only for names actually rewritten). Forward map is applied to tool
   defs, `tool_choice`, and historical assistant tool_calls in messages.
   Reverse map is threaded through both the non-streaming and streaming
   response paths so callers continue to see their original tool names
   in `tool_use` blocks.

2. OpenAPI -> MCP generator: sanitize `operationId` (and the
   method+path fallback) at registration time so generated MCP tools are
   valid for any strict-name provider, not just Anthropic. The dashboard
   preview endpoint applies the same sanitization for parity.

Includes unit tests covering: collision disambiguation between
`foo_bar` and `foo/bar` in the same request, reverse-map only firing
for actually-rewritten names, message rewrite for historical tool_calls,
streaming chunk_parser reverse-mapping, and sanitization of OpenAPI
operationIds plus the preview endpoint output.

* fix(anthropic): build tool-name maps in transform_request, not optional_params

The previous patch stashed the per-request forward and reverse tool-name
maps under ``optional_params["_anthropic_tool_name_forward_map"]`` and
``optional_params["_anthropic_tool_name_map"]``. ``optional_params`` is
the dict that becomes the JSON body via ``data = {**optional_params}``,
so those internal keys leaked over the wire and Anthropic 400'd with:

  _anthropic_tool_name_forward_map: Extra inputs are not permitted

Worse, this meant *every* request whose tool list contained any name with
an invalid character (the exact case the patch was meant to fix) regressed
into a confusing meta-error pointing at LiteLLM's internal map instead of
the offending tool.

Fix: move all tool-name sanitization into ``transform_request``, which is
the single chokepoint already shared by ``AnthropicConfig``,
``AmazonAnthropicConfig`` (Bedrock invoke), ``VertexAIAnthropicConfig``,
and ``AzureAnthropicConfig`` (all call ``super().transform_request`` /
``AnthropicConfig.transform_request(self, ...)``). New static helper
``_sanitize_tool_names_in_request`` walks the already-Anthropic-shaped
``optional_params["tools"]`` (only ``type=="custom"`` entries -- hosted
tool names are reserved by Anthropic and must not be touched), builds
the per-request forward/reverse maps, and applies the forward map in
place to ``tools[*].name`` and ``tool_choice.name``. The reverse map is
stashed exclusively on ``litellm_params`` (which is never serialized to
a provider) under ``_anthropic_tool_name_map`` for the response paths
to consume.

Side effect of this restructure: ``map_openai_params`` is now a pure
OpenAI->Anthropic param translator with no side-channel state, which
matches its contract everywhere else in the codebase.

Tests: replaced the now-incorrect "stashes maps in optional_params"
tests with regressions that assert no underscore-prefixed keys appear
in either ``optional_params`` after ``map_openai_params`` or in the
final ``transform_request`` body. Added end-to-end coverage for:
sanitization in ``transform_request``, ``tool_choice`` rewriting,
historical ``tool_calls`` rewriting in messages, and hosted-tool
passthrough.

* fix(anthropic): always sanitize empty text content blocks

Anthropic 400s on `{"role": "user", "content": ""}` with:
  "messages: text content blocks must be non-empty"

LiteLLM already had `_sanitize_empty_text_content` to rewrite empty text
to a placeholder, but it was gated behind `litellm.modify_params=True`.
With that flag off (default), empty content from upstream agent
frameworks (e.g. pydantic-ai) flowed straight through and tripped the
Anthropic validator.

Fix:
- Always run `_sanitize_empty_text_content` at the top of
  `anthropic_messages_pt`, independent of `modify_params`. There is no
  way to "pass through" an empty text block, so this is non-optional.
  The richer tool-call sanitizations (Cases A/B/D, which actually
  mutate conversation structure) remain gated on `modify_params`.
- Extend `_sanitize_empty_text_content` to also handle list-of-blocks
  content (`[{"type": "text", "text": ""}]`), not just string content.

Adds 3 regression tests covering string content, list-of-blocks
content, and the no-op case (non-empty messages with modify_params off).

* fix(anthropic): drop dead tool-name forward-map params, fix mypy + caller-mutation

- remove unused `name_forward_map` param from `_map_tool_choice`,
  `_map_tool_helper`, `_map_tools` and the `_apply_anthropic_tool_name_forward`
  helper. Production sanitization runs in `_sanitize_tool_names_in_request`
  at `transform_request`; these params were never threaded through.
- handler.py: use `ANTHROPIC_TOOL_NAME_REVERSE_MAP_KEY` constant instead of
  the hardcoded `"_anthropic_tool_name_map"` string.
- fix mypy `"object" has no attribute "__iter__"` in
  `_rewrite_tool_names_in_messages` by guarding `tool_calls` with
  `isinstance(..., list)`.
- `_sanitize_tool_names_in_request`: build a new tools list with copy-on-
  change entries (and copy `tool_choice` on rewrite) so a caller reusing
  the same tool list/dicts across requests doesn't see its inputs
  permanently rewritten.
- doc-comment `_build_request_tool_name_maps` clarifying it operates on
  OpenAI-format tools (vs `_sanitize_tool_names_in_request` which runs
  on Anthropic-format tools post-`_map_tools`).
- tests: drop 3 tests pinning the now-removed param paths; add coverage
  for tool_calls + None function_call rewrite and caller-dict immutability.

* fix(mcp): inherit stored credentials in test/tools/list for edit flow

When editing an existing MCP server, the Tool Configuration preview
calls POST /mcp-rest/test/tools/list with server_id but no credentials
(management API redacts them). The endpoint now calls
_inherit_credentials_from_existing_server() so stored bearer tokens
and OAuth2 M2M credentials are loaded from global_mcp_server_manager
automatically — tools load without re-entering credentials.

New servers (no server_id) and requests with explicit credentials are
unaffected (function is a no-op in both cases).

* fix(mcp): show all tools in edit panel, not just allowed tools

Edit flow was passing externalTools (from GET /tools/list, filtered by
allowed_tools) to MCPToolConfiguration, disabling the internal hook.
Remove the external props so the internal hook fires via
POST /test/tools/list, which returns all tools unfiltered. Combined
with the credential inheritance fix, tools load automatically without
re-entering credentials and all tools are visible for re-configuration.

existingAllowedTools still pre-checks previously allowed tools.

* Fix order-dependent collision in _build_anthropic_tool_name_maps

Use a two-pass approach: first pre-register all already-valid tool names
in the 'used' set, then sanitize/disambiguate names that need rewriting.
This ensures valid names always have priority regardless of input order,
preventing duplicate tool names on the wire when e.g. 'foo/bar' appears
before 'foo_bar' in the tool list.

Add regression test for the reversed ordering case.

* Fix OpenAPI tool name collision: disambiguate sanitized names with numeric suffixes

sanitize_openapi_tool_name replaces all invalid chars with '_', but when
two operationIds differ only by sanitized characters (e.g. 'foo/list' and
'foo.list' both become 'foo_list'), the second registration silently
overwrites the first in the tool registry.

Add collision disambiguation in register_tools_from_openapi that appends
_2, _3, ... suffixes when a sanitized name is already taken, mirroring
the existing logic in _build_anthropic_tool_name_maps.

* Fix preview endpoint missing collision disambiguation for tool names

Add used_names tracking and _2/_3 suffix disambiguation to
_preview_openapi_tools, matching the logic in register_tools_from_openapi.
Without this, two operationIds that sanitize to the same string (e.g.
'foo/list' and 'foo.list' both becoming 'foo_list') would show duplicate
names in the preview while registration would disambiguate them.

* Align preview HTTP method order with register_tools_from_openapi

The preview endpoint and register_tools_from_openapi both use
order-dependent collision disambiguation (_2, _3 suffixes). When the
iteration order differs, two operations on the same path with sanitized
names that collide get different suffixes in preview vs registration,
so the dashboard shows names that don't match what actually got
registered.

Also adds a regression test that fails on the swapped order.

* Skip duplicate originals in _build_anthropic_tool_name_maps

If the same invalid tool name appeared twice in original_names (e.g.
['foo/bar', 'foo/bar']), the second occurrence overwrote the forward
map entry with a freshly-suffixed name (foo_bar_2), leaving foo_bar
orphaned in 'used' with no reverse mapping. _sanitize_tool_names_in_request
then rewrote both tool entries to foo_bar_2, and Anthropic 400'd on
duplicate tool names.

Skip the rewrite if forward already has the original mapped.

userandClaude Opus 4.7 8ee599aa7d fix(mcp): use canonical proxy_logging_obj, deny when MCP server is unresolvable
Greptile flagged two follow-ups on the OpenAPI/local-registry pre-call
check:

1. **P1 runtime crash via None proxy_logging_obj.**
   `kwargs.get("proxy_logging_obj")` is `None` on the MCP entry path,
   and `pre_call_tool_check` calls `proxy_logging_obj._create_mcp_request_object_from_kwargs`
   unconditionally after the security checks, which would have crashed
   every legitimate call with `AttributeError`. Source the logging
   object from `litellm.proxy.proxy_server` the same way
   `_handle_managed_mcp_tool` already does.

2. **P2 authorization-bypass window when mcp_server is None.**
   Previously the new check was guarded by `if mcp_server is not None`,
   so any local tool whose registry entry had no resolvable server (a
   startup-race window before `_initialize_tool_name_to_mcp_server_name_mapping`
   completes, or an orphaned registry entry) ran without the security
   check. Tools registered via openapi_to_mcp_generator are always tied
   to a server, so a missing one is a configuration/timing fault — fail
   the call with 503 instead of dispatching unguarded.

Tests: existing two pass with an added assertion that
`proxy_logging_obj` is non-None at the call site, plus a new test that
covers the 503 deny branch when the tool→server mapping is missing.

userandClaude Opus 4.7 5daf0168a8 fix(mcp): run pre_call_tool_check on OpenAPI/local-registry path (VERIA-7)
`execute_mcp_tool` dispatches in two ways: managed MCP servers go
through `_handle_managed_mcp_tool`, which calls
`MCPServerManager.pre_call_tool_check` to enforce allowed/banned tool
lists, key/team `object_permission` tool grants, and parameter
validation. OpenAPI-backed tools, however, were resolved via
`global_mcp_tool_registry` and dispatched directly to
`_handle_local_mcp_tool` — entirely skipping `pre_call_tool_check`.

A caller could invoke any registered OpenAPI tool regardless of their
key/team permissions, including administrative or destructive
operations on the upstream API.

Run `pre_call_tool_check` before the local-registry dispatch whenever
the resolved server is set (the same condition used to surface server
context to the managed path). Honor any guardrail-modified arguments
the hook returns. Errors raised by the hook propagate up before
`_handle_local_mcp_tool` runs.

Tests cover both directions: the pre-call hook fires when the local
tool resolves alongside a server, and a hook-raised HTTPException
prevents the local handler from being invoked.
