* docs: add native thinking param examples for Claude Opus 4.6
Add documentation for using the native `thinking` parameter directly
with adaptive thinking and explicit budgets for Claude Opus 4.6.
* docs: add note about reasoning_effort mapping to adaptive for Opus 4.6
OAuth tokens (sk-ant-oat*) require Authorization: Bearer header per
Anthropic's OAuth specification, but were being sent via x-api-key
which Anthropic rejects with 'invalid x-api-key'.
- optionally_handle_anthropic_oauth: detect OAuth tokens in api_key
param (standard chat flow), not just Authorization header
- get_anthropic_headers: use Authorization: Bearer + required OAuth
headers for OAuth tokens, x-api-key for regular API keys
- Passthrough messages: skip x-api-key when Authorization is set
- Add oauth-2025-04-20 to beta headers whitelist config
* feat: add curated MCP server registry for discovery UI
Curated list of 31 well-known MCP servers with names, icons,
categories, transport config, and registry URLs. Includes HTTP
endpoints for GitHub, Atlassian, Sentry, Snowflake, and Cloudflare.
* feat: add GET /v1/mcp/discover endpoint for MCP discovery
Admin-only endpoint that serves the curated MCP registry with
optional query and category filters. Used by the UI discovery modal.
* feat: add DiscoverableMCPServer types for MCP discovery
* feat: add fetchDiscoverableMCPServers network function
* feat: add MCP discovery modal component
Compact list-row layout with category filters, search, and
grouped server list. Follows dev-tool aesthetic.
* feat: wire MCP discovery modal into server management page
Add MCP Server button now opens discovery modal. Card click
pre-fills the create form. Custom Server opens blank form.
* feat: add prefill from discovery and back-to-registry link
Create form accepts prefillData from discovery selection and
shows a Browse MCP Registry link to return to discovery modal.
* test: add unit tests for MCP discovery endpoint and registry
Tests for registry JSON structure validation and endpoint
query/category filtering logic. 15 tests total.
* fix: sync registry with official MCP API and fix stdio prefill

Fixes#20990
PR #19943 added logging when the proxy overrides model names to prevent
internal provider prefixes from leaking to clients. The behavior works
correctly but logs a WARNING on every request with model mismatch.
For high-traffic customers using model aliases or provider prefixes,
this creates millions of warnings per day, flooding logs and causing
disk space issues.
Changed log level from WARNING to DEBUG since:
- The model mismatch is expected behavior when using aliases
- The override happens correctly regardless of log level
- Operators can still enable with LITELLM_LOG=DEBUG for debugging
Changes:
- common_request_processing.py: 2 warnings -> debug (non-streaming)
- proxy_server.py: 1 warning -> debug (streaming)
- Change error message to be generic (works for both server_name and alias)
- Restore 'Defaults to server name with spaces replaced' text in alias tooltip
* fix: inject NPM_CONFIG_CACHE into STDIO MCP subprocess env for Docker
npm/npx needs a writable cache directory. In containers the default
(~/.npm) may not exist or be read-only, causing STDIO MCP servers
launched via npx to fail with ENOENT. Inject NPM_CONFIG_CACHE=/tmp/.npm_mcp_cache
into the subprocess env when not already set.
* test: add unit test for NPM_CONFIG_CACHE injection in STDIO MCP
Verifies that NPM_CONFIG_CACHE is auto-injected when not set, and
preserved when explicitly provided. Also moves the import to module
level per code style rules.
* Update litellm/constants.py

- Update validateMCPServerName to reject both spaces and hyphens
- Apply shared validation to alias field in create form (was inline)
- Update tooltips to mention space restriction
- Ensures consistency across create/edit forms for server_name and alias fields
Replace per-call .model_fields.keys() allocations and linear-scan membership
checks with module-level frozenset constants and dict.keys() set difference.
Defer locals() from hot path to except block. 617µs → 524µs/call.
