fix(mcp): OAuth2 chat connect - tools fetch, auth, and status fixes (#23406)
* fix(mcp): OAuth2 chat connect - tools fetch, auth flow, and status fixes

- schema.prisma: add missing MCP table fields (approval_status, submitted_by, submitted_at, reviewed_at, review_notes) to prevent destructive migrations
- rest_endpoints.py: inject user OAuth token via extra_headers for OAuth2 servers so tools list is populated; add server name->UUID resolution so MCPConnectPicker name lookups work
- mcp_registry.json: fix Atlassian defaults (transport: http, url: .../v1/mcp)
- ChatPage.tsx: read mcpOauthReturn param to init sidebarView="apps" on OAuth return, clean up param after mount
- MCPAppsPanel.tsx: auto-add OAuth2 servers to selectedServers when credential detected; onConnect also enables server for chat; disconnect removes from selectedServers
- mcp_servers.tsx: sort servers by created_at DESC
- useUserMcpOAuthFlow.tsx: append mcpOauthReturn=apps to return URL so Apps panel is mounted on return

* 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

* address greptile review feedback (greploop iteration 3)

* address greptile review feedback (greploop iteration 4)

* address greptile review feedback (greploop iteration 5)

* redesign credentials table to use Tremor table layout matching Keys page

* fix: /server/oauth authorize 422 - make client_id optional, fall back to real DB server

* fix: mcp_token client_id optional, resolve from server record

* fix: look up real server by UUID (get_mcp_server_by_id) before falling back to name

* Update litellm/responses/mcp/litellm_proxy_mcp_handler.py

* fix: address greptile feedback - client_id guards, dict spread, helper refactor, tests

- mcp_management_endpoints: raise 400 when resolved_client_id is empty in
  mcp_authorize and mcp_token instead of forwarding "" to upstream
- litellm_proxy_mcp_handler: use {**tool, "server_url": ...} spread instead
  of dict(tool) + mutation for shallow copy safety
- rest_endpoints: extract _oauth2_server_ids set comprehension to a named
  _get_oauth2_server_ids() helper for clarity; add Set to typing imports
- test_rest_endpoints: add tests for name→UUID resolution path,
  access-denied when resolved UUID not in allowed list, and OAuth2 user
  token injection for single-server requests; fix fake_get_tools signature
  to accept extra_headers kwarg

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/test_litellm

This folder can only run mock tests.
