Peter Dave Hello 3f18cd2fdc [Docs] Fix "Page Not Found" link for Anthropic endpoint (#23349 )

* fix(anthropic): enforce type:'object' on tool input schemas

Anthropic's API requires all tool input_schema to have type:'object'
at the root level. When OpenAI-format tools have parameters with a
missing or non-'object' type field (common with MCP tool servers),
the schema was passed through unchanged, causing Anthropic to reject
with: 'tools.N.custom.input_schema.type: Input should be object'.

The existing default handles the case where parameters is entirely
missing, but does not normalize schemas that ARE provided with a
wrong or absent type field.

Fix: After extracting _input_schema in _map_tool_helper(), ensure
type is set to 'object' and properties exists. This matches the
normalization already done implicitly by the Bedrock handler.

Added 4 unit tests covering: missing type, wrong type, valid schema
(no-op), and entirely missing parameters.

Related issues: #12020, #64, #1671

* fix(anthropic): deduplicate tool_result messages by tool_call_id

Anthropic requires exactly one tool_result per tool_use. When
conversation history (e.g. from session resume/checkpoint restore)
contains duplicate tool result messages with the same tool_call_id,
the API rejects with: 'each tool_use must have a single result.
Found multiple tool_result blocks with id: <id>'.

This is already handled for Bedrock via _deduplicate_bedrock_tool_content()
but was missing from the Anthropic direct and Vertex AI partner paths,
which share sanitize_messages_for_tool_calling().

Fix: Add Case D to sanitize_messages_for_tool_calling() — after the
existing orphan detection passes, scan for duplicate tool_call_ids
and keep only the last occurrence (most complete result).

Added 3 unit tests: dedup with duplicates, no-op with unique IDs,
and behavior when modify_params=False.

Related issues: #11804, #11029, #6836, #1782, #151

* fix: shallow copy input_schema to avoid caller mutation + add mutation guard test

Addresses Greptile review:
- dict(_input_schema) before mutation prevents cross-provider state leakage
- Test asserts original tool parameters dict is unchanged after call

* feat: add qwen3.5 series for openrouter

* fix: typo on max_output_tokens and max_tokens from qwen3.5 series

* chore: fix

* chore: fix

* [Test] UI - Logs: Add unit tests for 5 untested view_logs components

Add vitest tests for TypeBadges, ErrorViewer, ConfigInfoMessage, TimeCell, and TruncatedValue covering rendering, user interactions, and edge cases.

* Rename 'Team-Based Guardrails' to 'Team Bring-Your-Own Guardrails' (#23307)

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

* feat(chat-ui): responses API + MCP tool execution in /chat (#23297)

* feat(ui): add Chat UI v0 — standalone LiteLLM-branded chat window

Adds a full chat UI accessible from the sidebar Chat link (opens in new tab).
- Standalone route at /chat (outside dashboard layout — no Navbar/Sidebar chrome)
- Claude.ai-style layout: model selector top-left, LiteLLM logo center, settings top-right
- Greeting with time-of-day, centered input card, suggestion chips (Write/Learn/Code/Brainstorm)
- Sliding conversation history sidebar with Cmd+K search, rename, delete, date grouping
- localStorage-backed conversation persistence (litellm_chat_history_v1)
- Streaming completions via makeOpenAIChatCompletionRequest with AbortController stop support
- MCP server picker (toggle servers on/off per conversation)
- LiteLLM aesthetic: white/light-gray background, Ant Design blue (#1677ff) primary, system font
- Sidebar2: Chat menu item opens in new tab via window.open

* feat(chat-ui): responses API + MCP tool execution display

- Switch /chat from chat completions to responses API (previous_response_id session chaining)
- Add MCP server picker with search filter in chat input bar
- Show MCP tool call events (list_tools + call_tool) inline in chat via MCPEventsDisplay
- Add tool chip strip showing available tools when MCP servers are selected
- Non-blocking MCP toggle: server added immediately, verification in background (works for no-auth MCPs like deepwiki)
- Add truncateAfterMessage to useChatHistory for edit/retry
- Sync activeConversationId on URL change (fixes stale conversation on new chat)
- Add "Open Chat" shortcut button to sidebar

* fix(chat-ui): switch to responses API, remove dead code, add tests

- Switch handleSend from makeOpenAIChatCompletionRequest to makeOpenAIResponsesRequest with previous_response_id session chaining
- Add responsesSessionId state; reset to null when starting a new conversation
- Remove unused ChatInputBar.tsx and ModelSelector.tsx (dead code)
- Add tests/test_litellm/test_chat_ui_responses_session.py covering previous_response_id forwarding and signature validation

* fix(chat-ui): address greptile review issues

- Reset responsesSessionId when activeConversationId changes (not just on new conversation)
- Wire onMCPEvent callback into makeOpenAIResponsesRequest; render MCPEventsDisplay below messages
- Clear mcpEvents on each new send
- Explicitly filter history to user/assistant roles only (no tool-role casting)
- Remove duplicate "Chat" menu item from sidebar (pinned button serves same purpose)
- Make Sider a flex column so "Open Chat" button actually pins to bottom
- Fix tests to intercept real HTTP requests and assert previous_response_id in body

* fix(chat-ui): address greptile review feedback (greploop iteration 1)

- Fix duplicate context: when responsesSessionId is set, only send the
  new user message as input (prior context is already server-side via
  session chaining). Full history is still sent on the first turn.
- Fix ephemeral MCP events: store events per-message in ChatMessage.mcpEvents
  instead of ephemeral component state. Events now survive across turns
  and render inline below each assistant response via MCPEventsDisplay.
- Remove stale mcpEvents useState and ephemeral panel at bottom of chat.

* fix(chat-ui): address greptile review feedback (greploop iteration 2)

- Fix stale session on edit/retry: derive previousResponseId as null when
  historyOverride is set so edit/retry always starts a fresh Responses API
  session rather than chaining off a now-invalid prior session
- Fix unsafe MCPEvent cast: import MCPEvent directly from MCPEventsDisplay
  into types.ts and type ChatMessage.mcpEvents as MCPEvent[], eliminating
  the bare 'as MCPEvent[]' cast in ChatMessages.tsx

* fix(chat-ui): fix MCPEvent layering, batch localStorage writes, module-level test imports

- Move MCPEvent interface definition into chat/types.ts (single source of truth)
- MCPEventsDisplay.tsx now imports MCPEvent from types.ts instead of defining it locally
- Batch MCP event localStorage writes: accumulate during stream, persist once in finally
- Move test imports to module level per PEP 8 convention

* fix(chat-ui): fix MCPEvent import path and rename truncateFromMessage

- responses_api.tsx now imports MCPEvent directly from chat/types (not via MCPEventsDisplay re-export)
- Remove the now-unnecessary MCPEvent re-export from MCPEventsDisplay.tsx
- Rename truncateAfterMessage → truncateFromMessage: the function removes the target message and all subsequent ones (not just what comes after), so the new name accurately describes the behavior

* fix(responses-api): fix whitespace token filter and MCP server URL construction

- Drop the delta.trim() whitespace filter that was silently swallowing spaces
  and newlines during streaming, causing words to concatenate and paragraphs
  to collapse. Only skip truly empty strings (delta.length > 0).
- Use proxyBaseUrl for MCP server_url construction instead of the hardcoded
  relative path "litellm_proxy/mcp", so non-root deployments route correctly.

* fix(responses-api): use unique server_label per MCP server to prevent tool routing collisions

* fix(chat-ui): move MCPEvent to shared mcp_tools/types, skip partial events on abort

- Move MCPEvent interface to mcp_tools/types.tsx (shared with MCPServer/MCPTool),
  eliminating the playground→chat cross-module dependency. chat/types.ts and
  both playground components now import from mcp_tools/types.
- Only persist accumulated MCP events when the stream completes cleanly; aborted
  or errored turns drop partial events to avoid showing incomplete tool calls.

* fix(responses-api): use server_name for MCP URL routing, fix test path

- Use server_name (not alias) as the URL path segment for MCP server_url;
  alias is a display name that may differ from the registered proxy route.
  URL-encode the path to handle names with spaces/special characters.
- Fix sys.path.insert in tests to use __file__-relative path so tests pass
  regardless of which directory pytest is invoked from.

* fix(chat-ui): fix stale session after failed edit, clean MCP event persistence, unique server_label

- Eagerly call setResponsesSessionId(null) when historyOverride is set so a
  failed/aborted edit does not leave a stale session contaminating the next turn
- Replace abort-signal check with streamCompletedCleanly flag to correctly skip
  MCP event persistence on both abort and non-abort errors (network/API failures)
- Use server_name (unique) as server_label instead of alias to prevent silent
  tool-routing failures when two MCP servers share the same display name

* [Feat] UI - Show logos on MCP Apps page (#23320)

* feat(ui): add MCP server logo support across admin and chat UIs

- New MCPLogoSelector component with grid of well-known logos (GitHub,
  Slack, Notion, Linear, Jira, etc.) and custom URL input
- Create MCP Server form: logo picker with preview, OpenAPI presets
  auto-fill logo from registry icon_url
- Edit MCP Server form: logo picker pre-populated from mcp_info.logo_url
- Admin table: logos rendered next to server name in Name column
- Chat MCPAppsPanel: logos on server cards (list + detail view) with
  graceful fallback to letter avatars
- Chat MCPConnectPicker: logos next to server names in toggle list
- Fix pre-existing bug: setTools -> clearTools in create form cancel
- All 321 vitest files / 3211 tests pass

* feat(ui): use local SVG logos for MCP services, fix Chat UI rendering

- Add 15 new MCP service logo SVGs (Slack, Notion, Linear, Jira, Figma,
  Gmail, Stripe, Salesforce, Shopify, HubSpot, Twilio, Sentry, Zapier,
  GitLab, Google Drive) to both source and pre-built directories
- Switch MCPLogoSelector from CDN URLs (cdn.simpleicons.org) to local
  asset paths (/ui/assets/logos/) for reliable rendering
- Logos now served by the proxy itself, working from any page path
  including /ui/chat/ (absolute paths resolve correctly everywhere)

* fix(codeql): remove ruby from language matrix (#23227)

* Add team-scoped MCP server filtering for key creation and fix UnboundLocalError

When creating a key, the MCP server list now filters by the selected team's
allowed servers. Also fixes UnboundLocalError on `is_restricted_virtual_key`
when `team_id` query param was provided to GET /v1/mcp/server.

* Fix cross-team MCP server info disclosure and restricted key bypass

The GET /v1/mcp/server endpoint allowed any authenticated user to pass
an arbitrary team_id and enumerate another team's MCP server config.
Restricted virtual keys could also use the team_id param to bypass
their access limitations. Add team membership check for non-admins
and block restricted keys from using the team_id filter.

* [Feature] UI - MCP Servers: Add per-server health recheck

Allow users to recheck health for individual MCP servers by clicking
the health status badge. On hover the badge text changes to "Recheck"
with a refresh icon, and the check runs only for that server.

* Fix Anthropic docs link for beta endpoint

Update the Anthropic /v1/messages beta endpoint docstring to point to
its current pass-through documentation.

This keeps the change scoped to the incorrect URL and avoids changing
unverified wording in the surrounding comment.
