* feat(mcp): parallelize tool fetching from multiple MCP servers (#18627)
* feat(mcp): parallelize tool fetching from multiple MCP servers
Replace sequential tool fetching with asyncio.gather() to reduce
client timeouts when using multiple MCP servers.
Changes:
- mcp_server_manager.py: list_tools() now fetches tools in parallel
- server.py: _get_tools_from_mcp_servers() now fetches tools in parallel
Real-world impact (7 MCP servers example):
- Sequential: ~4.5+ seconds (exceeds typical 5-second client timeouts)
- Parallel: ~1.2 seconds (max of all servers)
Fixes#18626
* fix: copy oauth2_headers to avoid shared dict mutation in parallel tasks
* feat: add display_name, model_vendor, and model_version metadata
* added the option of adding langsmith tenant id in the env (#18623)
* fix(router): Validate routing_strategy at startup to fail fast with helpful error. (#18624)
Invalid routing_strategy values (e.g., "simple" instead of "simple-shuffle") previously failed silently, causing confusing "No deployments available" errors downstream. This change adds upfront validation in routing_strategy_init() to:
- Check if the provided strategy matches valid string values or RoutingStrategy enum
- Raise a clear ValueError listing valid options if invalid
- Fail fast at startup instead of at request time
Fixes behavior reported in #11330 where users had to debug cryptic errors.
Valid strategies: simple-shuffle, least-busy, usage-based-routing, latency-based-routing, cost-based-routing, usage-based-routing-v2

* Add libsndfile to database Docker image for audio processing (#18612)
The litellm-database Docker image was missing the libsndfile system
library, which is required by the soundfile Python package for audio
file processing. This caused failures when using audio transcription
endpoints that attempt to calculate audio duration.
This adds libsndfile to the runtime dependencies in Dockerfile.database,
consistent with Dockerfile.alpine which already includes this library.
* Fix: Map Gemini cached_tokens to Langfuse cache_read_input_tokens (#18614)
* Fix: Map Gemini cached_tokens to Langfuse cache_read_input_tokens
Fixes#18520
## Problem
Langfuse integration was not capturing cached tokens from Gemini models.
Gemini returns cached tokens in `usage.prompt_tokens_details.cached_tokens`,
but Langfuse only read from top-level `usage.cache_read_input_tokens`
(which only Anthropic populates).
## Solution
Updated langfuse.py to check both locations:
1. First check top-level cache_read_input_tokens (for Anthropic)
2. Then check prompt_tokens_details.cached_tokens (for Gemini, OpenAI, others)
This ensures all providers' cached tokens are properly reported to Langfuse.
## Changes
- Modified litellm/integrations/langfuse/langfuse.py (lines 742-761)
- Added 3 unit tests in tests/test_litellm/integrations/langfuse/test_gemini_cached_tokens.py
- All existing Langfuse tests still pass (11/11)
## Testing
- test_cached_tokens_extraction: Verifies Gemini cached_tokens extraction
- test_cached_tokens_not_present: Backward compatibility (no cached_tokens)
- test_cached_tokens_is_zero: Edge case when cached_tokens = 0
* Refactor: Extract cache token logic into helper function
Address review feedback from @officer47p
- Created _extract_cache_read_input_tokens() helper function
- Reduces code bloat in _log_langfuse_v2 method
- Improves testability and reusability
- All tests still passing (11/11)

* fix(streaming): normalize status code extraction to prevent 4xx errors from triggering mid-stream fallback (#18698)
在流式处理错误时，添加状态码标准化逻辑，确保 4xx 客户端错误直接抛出而不是被包装成 MidStreamFallbackError。
- 新增 _normalize_status_code 函数用于从异常对象提取状态码
- 优先从异常的 status_code 属性获取，其次从 response.status_code 获取
- 当映射异常或原始异常的状态码在 400-499 范围内时，直接抛出映射异常
- 添加单元测试验证 Vertex AI 400 错误正确抛出为 BadRequestError
- 确保流式处理中的客户端错误能够正确传播，而不会触发回退机制

Calculate `total_tokens` in usage data in Response manually if:
- `total_tokens` is missing
- `total_tokens` can be calculated from input and output tokens
Run the test for this feature with:
`poetry run pytest tests/test_litellm/responses/test_responses_utils.py -k "test_transform_response_api_usage_calculates_total_from_input_and_output_tokens_if_available" -v`
