* fix(proxy): make async_post_call_response_headers_hook consistent across all endpoints
The response headers hook had 5 gaps that prevented callbacks from
reliably extracting routing metadata across endpoint types:
1. Hook never fired for /audio/transcriptions (endpoint bypasses
base_process_llm_request)
2. custom_llm_provider not accessible in hook data for any endpoint
3. custom_llm_provider not stamped in ResponsesAPIResponse._hidden_params
(unlike chat completions)
4. model_info under inconsistent keys (metadata vs litellm_metadata)
5. request_headers always None at all call sites
This adds a litellm_call_info parameter to the hook that normalizes
routing metadata (custom_llm_provider, model_info, api_base, model_id)
regardless of endpoint type. Also stamps custom_llm_provider on
Responses API responses, adds the hook call to the transcription
handler, and passes request_headers at all call sites.
Supersedes PR #21385.
* fix(proxy): address review feedback — safer backwards compat and None guards
- Replace try/except TypeError with inspect.signature() check for
litellm_call_info backwards compatibility. This avoids masking real
TypeErrors inside callback implementations and prevents double
invocation with inconsistent parameters.
- Use (data.get("key") or {}) instead of data.get("key", {}) to guard
against keys that exist with an explicit None value, which would
cause AttributeError on the subsequent .get() call.
* fix(proxy): cache inspect.signature result for callback compat check
Move the inspect.signature() call into a module-level helper with a
dict cache keyed by callback identity. Avoids repeated introspection
per request per callback in the hot path.
* fix(proxy): use class identity for signature cache key
Key the _CALLBACK_ACCEPTS_CALL_INFO cache by id(type(cb)) instead of
id(cb) to avoid stale entries from Python address reuse after GC.
All instances of the same callback class share the same method
signature, so class identity is both safer and more cache-efficient.

* address greptile review feedback (greploop iteration 1)
* fix(mcp): inject stored OAuth2 token when fetching tools via /responses API
When a user has connected an OAuth2 MCP server (e.g. Atlassian) and then
uses the /responses endpoint with that server, tool listing was failing
because the stored per-user OAuth token was never injected.
Two fixes:
1. server.py: add _get_user_oauth_extra_headers_from_db() helper; call it
in _get_tools_from_mcp_servers when oauth2_headers is None for an OAuth2
server, falling back to the user's stored token in LiteLLM_MCPUserCredentials
2. litellm_proxy_mcp_handler.py: also intercept MCP tools whose server_url
matches */mcp/<server_name> (e.g. http://localhost:4000/mcp/atlassian_test)
by rewriting them to litellm_proxy/mcp/<server_name> so they go through
the internal handler (and get the OAuth token injected) instead of being
forwarded to OpenAI raw where localhost is unreachable
* address greptile review feedback (greploop iteration 2)
* test(mcp): add unit test for OAuth2 token injection in _get_tools_from_mcp_servers
Verifies that when _get_tools_from_mcp_servers is called for an OAuth2 MCP
server without oauth2_headers in the request, the implementation:
- calls _prefetch_oauth_creds_for_user once (not per-server) to avoid N+1 queries
- passes the stored token as extra_headers={"Authorization": "Bearer ..."} to
_get_tools_from_server so the upstream OAuth2 MCP server authenticates correctly

Snowflake's Cortex LLM API (like Anthropic) requires tool_choice as an
object with a "type" field, not as a bare string. Passing tool_choice="auto"
(or "required"/"none") results in error 390142 "invalid payload".
This fix transforms OpenAI string tool_choice values to the Snowflake
object format:
- "auto" -> {"type": "auto"}
- "required" -> {"type": "any"} (Snowflake/Anthropic convention)
- "none" -> {"type": "none"}
The dict-to-dict transformation for specific function tool choices
({"type": "function", "function": {"name": "..."}} -> {"type": "tool",
"name": [...]}) remains unchanged.

* fix(mcp): fix OpenAPI OAuth flow — transport mapping, error messages, and discovery bypass
Three bugs fixed to make the end-to-end OAuth flow work for OpenAPI MCP servers:
1. **Transport mapping in getTemporaryPayload**: `TRANSPORT.OPENAPI` is a UI-only concept;
the backend only accepts `"http"`, `"sse"`, or `"stdio"`. The pre-OAuth temp-session
call was sending `transport: "openapi"` and getting a 422. Fixed by mapping to `"http"`.
2. **deriveErrorMessage handles FastAPI 422 arrays**: FastAPI validation errors return
`detail` as an array of `{loc, msg, type}` objects. The shared error extractor was
returning the array directly, causing `Error: [object Object]`. Fixed to map each
item to its `.msg` field.
3. **Skip OAuth discovery when authorization_url already provided**: `build_mcp_server_from_table`
was unconditionally calling `_descovery_metadata(server_url)` for OAuth servers. For
OpenAPI servers the url is the spec JSON file, not the API base — this caused a timeout
fetching e.g. the GitHub spec (2 MB). Fixed by skipping discovery when `authorization_url`
is already set.
Also: collapsible auth section in MCP server form, "Create OAuth App →" link next to
Client ID when a docs URL is available (e.g. GitHub OAuth App creation page), and
`extractErrorMessage` helper in `useMcpOAuthFlow` for cleaner error display.
* refactor(mcp): extract needs_discovery flag and reduceStaticHeaders helper
* feat(mcp): user OAuth connect flow — OAuthConnectModal, MCPCredentialsTab, useUserMcpOAuthFlow
Adds the user-facing MCP OAuth2 PKCE connect flow:
- OAuthConnectModal: modal that launches the PKCE flow for a user to connect to an MCP server
- MCPCredentialsTab: credentials management tab in the MCP apps panel
- useUserMcpOAuthFlow: hook that handles the full PKCE auth code exchange for user-level connections
- MCPAppsPanel: wires up the new credentials tab and connect modal
- ChatPage: further cleanup after responses-API revert
- db.py / mcp_management_endpoints.py / _types.py: backend support for storing user MCP credentials
* fix(mcp): make client_id optional in /authorize — use server's stored client_id when not provided
* address greptile review feedback
* fix(mcp): narrow bare except to RecordNotFoundError in BYOK credential delete
* refactor(mcp): move inline imports to module level in db.py
* docs(claude): add MCP OAuth, transport mapping, and browser storage patterns
* fix(security): remove accessToken from sessionStorage in OAuth flow state
The LiteLLM API key was being serialised into sessionStorage as part of
StoredFlowState. After the OAuth redirect the component re-mounts with the
same accessToken prop, so it never needed to be stored. Read it from props
in resumeOAuthFlow instead.
* fix(ui): remove duplicate extractErrorMessage, sessionStorage-only in admin OAuth hook, call delete API on disconnect
* fix(ui): guard resumeOAuthFlow against wrong hook instance consuming OAuth result
* fix(ui): separate OAuth result keys per flow, sessionStorage-only, surface revoke errors
* fix(ui): remove dead OAuthConnectModal, revert tsconfig jsx mode to preserve
* fix(mcp): guard BYOK overwrite in oauth credential store, raise clear error when client_id absent
* fix: forward OAuth error params in callback, fix BYOK guard exception handling in db.py
