Remove the isinstance(cost, dict) guard from Usage.__init__ — ResponseAPIUsage.parse_cost
validator already converts Perplexity's cost dict to float before it reaches Usage.
Add test_streaming_cost_dict_to_float_via_validator to verify the dict→float conversion
works end-to-end through transform_streaming_response (pydantic recursive construction).
* 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
Add usage example with concrete model entry, explanation of load-time
expansion, and cross-reference to model_alias_map to clarify the
difference between the two features.
Consolidate User Email and User ID columns into a single "User" column with
fallback display (Alias > Email > ID) and hover popover with copyable values.
Resolve Team and Organization columns to show aliases instead of raw UUIDs.

* 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
- Remove Perplexity-specific `models` field from ResponsesAPIOptionalRequestParams
TypedDict to avoid polluting the shared OpenAI type. The param is still passed
through via get_supported_openai_params + map_openai_params at runtime.
- Add transform_response_api_response override to catch Perplexity's HTTP 200
with status:"failed" and raise BaseLLMException instead of silently succeeding.
- Update test_all_supported_params_declared to match the simplified
8-param list (was 24 params from old 410-line implementation)
- Replace test_cost_transformation tests: use ResponseAPIUsage
validator directly instead of removed _transform_usage method
(cost parsing moved to generic parse_cost validator)
- Add 'models' field to ResponsesAPIOptionalRequestParams TypedDict so
the Perplexity fallback chain param is not silently filtered out by
get_requested_response_api_optional_param(). Verified with curl that
Perplexity's models param works (tries models in order until one
succeeds).
- Fix test_python_class_takes_priority_over_json: save and restore the
original JSONProviderRegistry entry instead of deleting it, preventing
state corruption for subsequent tests.
- Filter get_finish_reason_mapping() to Gemini-only keys instead of
returning the full cross-provider _FINISH_REASON_MAP
- Shallow-copy caller-supplied provider_specific_fields before mutating
to avoid unexpected side-effects
When a provider's finish_reason is mapped to a different OpenAI-compatible
value (e.g. "MALFORMED_FUNCTION_CALL" → "stop"), the original value is now
preserved in choices[].provider_specific_fields["native_finish_reason"].
This allows agent loops to distinguish between different stop conditions
without breaking the unified OpenAI-compatible finish_reason mapping.
Also returns a defensive copy from get_finish_reason_mapping() to prevent
accidental mutation of the global _FINISH_REASON_MAP.
- fix transport display: use handleTransport() instead of hardcoding HTTP/stdio based on server_url presence
- show available tools list when clicking into a server detail view
- preload tool counts per server card in parallel (one request per server, counts pop in independently)
- add skeleton loading indicator on each card while its tool count is fetching
- fix: pass server UUID (not name) to /mcp-rest/tools/list — name was always hitting access_denied
* feat(chat-ui): add MCP OAuth2 value prop and OAuth2 pill on server cards
- Add subtitle in chat empty state explaining MCP OAuth2 value prop with 'Open Apps' link
- Update MCPAppsPanel header copy to explain the flow more clearly
- Show OAuth2 pill badge on server cards where auth_type is oauth2
* fix(chat-ui): use AUTH_TYPE.OAUTH2 constant instead of hardcoded string
- Invert lookup order in get_provider_chat_config so Python classes
(with custom overrides) are checked before JSON providers, matching
the pattern already used in get_provider_responses_api_config.
Prevents regression where providers like Perplexity (declared in
providers.json) would silently lose their custom chat config.
- Add 'models' to Perplexity Responses API supported params (fallback
chain feature documented in Perplexity API).
* fix: guard prisma import in config_override_endpoints to fix proxy import without prisma
Top-level `from prisma.errors import RecordNotFoundError` was introduced in the
Hashicorp Vault feature PR and breaks `import litellm.proxy.proxy_server` when
prisma is not installed (e.g. plain `pip install litellm[proxy]` in CI).
Wraps the import in try/except ImportError so the module loads cleanly when
prisma is absent; the except branch aliases RecordNotFoundError to Exception,
which is safe because the code path that catches it only logs a debug message.
* fix: sync poetry.lock with pyproject.toml (litellm-proxy-extras 0.4.51 → 0.4.52)
poetry.lock was regenerated for 0.4.51 but pyproject.toml was subsequently
bumped to 0.4.52 without re-running poetry lock. This caused the
proxy_e2e_azure_batches_tests CI job to fail at the Install Dependencies step
('pyproject.toml changed significantly since poetry.lock was last generated'),
preventing all 3 tests in that job from running.
* Revert "fix: sync poetry.lock with pyproject.toml (litellm-proxy-extras 0.4.51 → 0.4.52)"
This reverts commit 249ec7c9c2.
* feat(ui): add OpenAPI MCP server support with popular API quick-picker
- New `openapi_registry.json` with 10 well-known APIs (GitHub, Atlassian, Figma, Google, Stripe, HubSpot, Notion, Slack, Shopify, Snowflake) — each with validated spec URLs and OAuth 2.0 endpoints
- Backend endpoint `GET /v1/mcp/registry.json` to serve the registry (reads fresh from disk)
- `OpenAPIQuickPicker` component: logo grid for popular APIs with letter fallback for broken images
- `OpenAPIFormSection` component: encapsulates picker + spec URL input as a clean unit
- When selecting a preset, spec URL and OAuth fields are pre-filled automatically
- Fixed `useTestMCPConnection`: for OpenAPI transport, tools load from the spec as soon as the URL is set — no auth type or OAuth token required
- Validated all spec URLs are reachable; removed Linear (GraphQL-only, no REST spec)
* feat(ui): add curated key tools preview for OpenAPI MCP servers
When selecting a popular API from the quick-picker, show the 8 most
useful MCP tools for that API in a collapsible preview card. First 4
are shown by default; clicking "expand" shows all 8 with descriptions
on hover.
- Added `key_tools` array (8 tools each) to all 10 APIs in openapi_registry.json
- New `KeyToolsPreview` component in OpenAPIFormSection with expand/collapse
- Extended `OpenAPIRegistryEntry` type with `key_tools?: OpenAPIKeyTool[]`
* fix(ui): move key tools preview inside Tool Configuration card
* fix(ui): pin suggested tools at top of tool list, fix TDZ crash, add per-section enable/disable
* fix: address greptile review - fix registry spec URLs, remove redundant dep, add error handling
* fix: restore enable/disable all buttons for non-preset MCP servers
* refactor: extract ToolRow component, move handlers to component body, fix key props
* fix: remove rewrites() from next.config.mjs (incompatible with output: export), fix OAuth field paths
* fix: enable/disable all operates on full tool set, not just filtered subset
* fix: cache openapi registry, make oauth optional, reset preset auto-select on new preset
* fix: use official Shopify API specs repo, move lru_cache error handling to caller
* fix: use Shopify 2023-10 REST spec, co-locate rest section header with tool rows
* fix: guard fuzzy-match against empty keywords, remove placeholder OAuth URLs for Shopify/Snowflake
* fix: lift useTestMCPConnection to parent to eliminate duplicate requests, clear keyTools on manual spec URL edit
* fix: clear stale OAuth fields when switching to non-OAuth preset, show expected tools on empty spec
* fix: gate registry fetch on modal visibility, use resetFields to clear OAuth fields
* feat(mcp): add BYOM (Bring Your Own MCPs) submission + admin review workflow
Non-admins can now submit MCP servers for review via POST /v1/mcp/server/register.
Admins get a Submissions tab in the UI to approve or reject pending servers.
Approved servers enter the active runtime; rejected ones stay out with notes.
- DB: add approval_status, submitted_by, submitted_at, reviewed_at, review_notes
to LiteLLM_MCPServerTable with migration
- Backend: new endpoints register, submissions, approve, reject
- reload_servers_from_database now only loads approval_status=active servers
- UI: Submissions tab with stat cards, card list, confirm dialogs; non-admin
"Submit MCP Server" button wired to /register endpoint
- Fix get_mcp_submissions to filter by submitted_at IS NOT NULL (not submitted_by,
which can be null for team-scoped keys without an associated user)
* feat(mcp): rename nav item to Team MCPs + add New badge
* fix(mcp): revert nav label, rename Submissions tab to Team MCPs + New badge
* feat(mcp): add MCP Standards — required fields config + CI-style checks on submissions
Adds a "Standards" tab (admin-only) to MCP Servers where admins define which
server fields are required for a submission to pass. Each submission card in
Team MCPs then shows a green ✓ or red ✗ for each required field, with a
summary "N/M checks" badge in the header — like GitHub CI status rows.
Also adds a `source_url` field (GitHub / Source URL) to the MCP server schema
so non-admins can link to the source repo when submitting a server.
- schema.prisma: add `source_url String?` to LiteLLM_MCPServerTable
- migration: 20260309000001_add_mcp_source_url
- _types.py: source_url on NewMCPServerRequest, UpdateMCPServerRequest, LiteLLM_MCPServerTable
- types.tsx: source_url on MCPServer interface
- create_mcp_server.tsx: GitHub/Source URL form field
- MCPStandardsSettings.tsx: new — toggle which fields are required (stored in general settings as mcp_required_fields)
- mcp_servers.tsx: Standards tab (admin-only)
- MCPSubmissionsTab.tsx: load required fields + CI-style check pills on each card
* refactor(mcp): move submission rules into Team MCPs tab, grouped free-form UI
Folds the Standards tab into Team MCPs. Submission Rules panel now lives at the
top of the Team MCPs tab — collapsible, shows active rules as chips when closed,
expands to a grouped checkbox editor (Documentation / Source / Connection /
Security). Removes the separate Standards tab from the nav.
MCPStandardsSettings.tsx is now constants-only (FIELD_GROUPS, MCP_REQUIRED_FIELD_DEFS,
SETTINGS_KEY) — the UI lives in MCPSubmissionsTab.
* feat(mcp): add mcp_required_fields to ConfigGeneralSettings + config/list endpoint
Registers mcp_required_fields as a proper general_settings field so the UI
can read/write it via /config/list and /config/field/update without the
"Invalid field" error. Also fixes a pre-existing pyright None-check issue
in _sync_ui_settings_to_general_settings.
* ui(mcp): GitHub-style PR checks panel on submission cards
* ui: rename Team MCPs -> Submitted Tools, Team Guardrails -> Submitted Guardrails
* address greptile review feedback (greploop iteration 1)
* fix: inline import, add approval workflow tests, rename Submitted MCPs
* fix(mcp): allow re-approval of rejected MCP server submissions
* fix(mcp): evict rejected servers from runtime; enforce mcp_required_fields on /register
* fix(mcp): sort submissions newest-first; force active status on admin-created servers
* fix(mcp): add missing mock in test, show Approve for rejected, clear submission metadata, drop spurious Content-Type
* fix(mcp/ui): show Reject for active servers; show submit form to non-admins with team-key note
* fix(mcp): conditional reload on reject; view-only admin for submissions; block admin from /register
* fix(mcp): match auth_type required-field validation to UI compliance check (reject 'none')
* fix(mcp): block view-only admin from /register; log settings failure; warn on active server reject
* fix(mcp): allow view-only admin to use /register; add _validate_mcp_required_fields tests
* fix(mcp): validate field names in mcp_required_fields; surface backend error in submit UI
* fix(mcp): fix falsy field check; add field-name validation; add take limit; document server-managed fields; close dialog on error
