* 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
Co-authored-by: greptile-apps[bot] <165735046+greptile-apps[bot]@users.noreply.github.com>
* 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

* feat(ui): group MCP tools by CRUD risk category in tool permission panels
Adds a CRUD-classification layer to the MCP tool allowlist UI so admins
can allow/block an entire risk category (Read / Create / Update / Delete)
with a single toggle instead of managing a flat list of individual tools.
- New `mcpToolCrudClassification.ts` utility: regex-based classifier that
buckets tool names/descriptions into read/create/update/delete/unknown
- New `McpCrudPermissionPanel` component: collapsible sections per CRUD
group, group-level Switch toggle, individual tool checkboxes, risk badges
(green Safe / yellow Medium / red High Risk)
- `mcp_tool_configuration.tsx`: adds "Risk Groups / Flat List" radio toggle;
defaults to the CRUD-grouped view, flat list is still accessible
- `MCPToolPermissions.tsx` (key/team assignment): replaces flat checkboxes
with the CRUD panel; adds per-server view toggle; delete tools are blocked
by default for newly-added servers (safer default for key/team scoping)
No backend or schema changes — uses existing `allowed_tools` and
`mcp_tool_permissions` fields.
* 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
* fix(mcp-crud-ui): address greptile review feedback
- use Checkbox (not Switch) for group toggle so indeterminate works
- add toolPermissionsRef to avoid stale closure race on concurrent server fetches
- remove unused blockDeleteByDefault prop from McpCrudPermissionPanel
- classify tools by name first; fall back to description only when name yields no match
- add Risk Groups / Flat List toggle to mcp_tool_configuration.tsx
* fix(mcp-crud-ui): address greptile 3/5 review
- remove non-functional XIcon remove-server button (no onRemoveServer prop wired)
- fix stale closure in MCPAppsPanel auto-enable effect: use serversRef/selectedServersRef
- remove utility re-export from McpCrudPermissionPanel (classifyToolOp, groupToolsByCrud)
- remove redundant selectedTools.length === 0 guard (always true when !toolPermissions[id])
* fix(mcp-crud-ui): address greptile 3/5 review round 2
- check READ_RE before DELETE_RE in classifyToolOp so tools like
get_removed_entries are not silently blocked by delete-by-default
- expand undefined (allow-all) to full tool name list instead of
collapsing to [] (allow-none) in MCPToolPermissions and mcp_tool_configuration
- log OAuth credential fetch failures instead of silently swallowing them
* fix: cursor-pointer on read-only rows, stable sort, simplify handleCrudPanelChange
* fix: sanitize user_id/server_id in log to prevent log injection
* fix: add OAuth headers to call_tool_rest_api, fix stale accessToken closure, fix group toggle on filtered subset
* fix: batch OAuth creds query, hide empty CRUD groups on search, onChange stability
* fix: double-add race, conditional bulk query, narrow DELETE_RE, hoist search input
* fix(mcp): clear oauthConnected on deselect; null guard on allowedTools prop
* fix(mcp): remove user-provided values from debug log to fix log-injection lint
* fix(mcp): fix allowedTools undefined semantics; remove unused import and color field
Expand the existing expand=user lookup on /key/list to also resolve
created_by user IDs, and display the result in the Created By column
with alias > email > UUID fallback and a popover showing all three.
* 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
* 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

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

GitLab, Google Drive) to both source and pre-built directories
- Switch MCPLogoSelector from CDN URLs (cdn.simpleicons.org) to local

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
