* 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: 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.

Fixes AT&T customer issue where API keys are returned in plain text
in error responses.
Changes:
1. user_api_key_auth.py: Mask the API key in the AssertionError when a
key doesn't start with 'sk-' (e.g. key with leading space). Shows
first 4 + last 4 chars with **** in between instead of the full key.
2. key_management_endpoints.py: Same masking for the key format
validation error when creating keys with invalid prefix.
3. presidio.py: Sanitize exceptions from Presidio analyze/anonymize
calls to prevent leaking original request text (which may contain
API keys) in error responses. Error messages now show only the
exception type, not the full payload.
* fix: empty guardrails/policies arrays should not trigger enterprise license check (#20304)
The UI sends empty arrays for enterprise-only fields (guardrails, policies,
logging) even when the user has not configured these features. The backend
`is not None` check treated `[]` as a truthy intent to use the feature,
falsely requiring an enterprise license for basic team operations.
Backend: Add `and updated_kv[field] != [] and updated_kv[field] != {}`
guards in `_update_metadata_fields` so empty collections are skipped.
UI: Conditionally omit guardrails, logging, and policies from the
payload when empty instead of defaulting to `[]`.
Fixes#20304
* fix: allow clearing fields with empty collections while skipping enterprise check
Address PR review feedback:
1. Move the empty-collection guard into _update_metadata_field (singular)
so that empty lists/dicts skip only the premium license check but still
get written into metadata. This lets users intentionally clear a
previously-set field (e.g. guardrails: []) without being blocked, while
the UI's default empty arrays still don't trigger a false enterprise
error.
2. Remove sys.path hack from test file; use standard imports that work
with pytest discovery.
3. Add tests verifying that empty collections are moved into metadata
(field clearing works) even though they bypass the premium check.
Fixes#20304
* fix(proxy): add regression tests for #20441 - ensure <script> tags in LLM messages are not blocked
The 403 Forbidden error when sending messages containing `<script>` is caused
by external WAF/reverse proxy infrastructure (confirmed by the standard nginx
HTML 403 response format), not by LiteLLM's own content filtering. However,
these regression tests ensure that:
1. The content filter guardrail's built-in patterns do not match HTML tags
2. Messages containing <script> and other HTML tags pass through the content
filter unchanged when no explicit HTML-blocking rules are configured
3. The HTTP request body parser correctly handles JSON payloads containing
HTML content without modification
These tests guard against accidentally introducing HTML/XSS filtering that
would break legitimate LLM API usage (e.g., discussing HTML/JavaScript code).
Closes#20441

- Track unnamed keys/teams as separate counts instead of inflating

* fix(azure): preserve content_policy_violation error details from Azure OpenAI
Closes#20811
Azure OpenAI returns rich error payloads for content policy violations
(inner_error with ResponsibleAIPolicyViolation, content_filter_results,
revised_prompt). Previously these details were lost when:
1. The top-level error code was not "content_policy_violation" but the
inner_error.code was "ResponsibleAIPolicyViolation" -- the structured
check only examined the top-level code.
2. The DALL-E image generation polling path stringified the error JSON
into the message field instead of setting the structured body, making
it impossible for exception_type() to extract error details.
3. The string-based fallback detector used "invalid_request_error" as a
content-policy indicator, which is too broad and could misclassify
regular bad-request errors.
Changes:
- exception_mapping_utils.py: Check inner_error.code for
ResponsibleAIPolicyViolation when top-level code is not
content_policy_violation. Replace overly broad "invalid_request_error"
string match with specific Azure safety-system messages.
- azure.py: Set structured body on AzureOpenAIError in both async and
sync DALL-E polling paths so exception_type() can inspect error details.
- test_azure_exception_mapping.py: Add regression tests covering the
exact error payloads from issue #20811.
- Fix pre-existing lint: duplicate PerplexityResponsesConfig dict key,
unused RouteChecks top-level import.

Replace 3 full tree traversals with 1 Pydantic dump + 3 dict lookups
per choice. Deletes _path_matches_pattern, _build_preserved_paths, and
_remove_none_except_preserved helpers (~140 lines removed). Adds 13
regression tests including full output structure snapshots.
OIDC providers like Logto may return opaque (non-JWT) access tokens,
which caused jwt.decode() to raise DecodeError and crash the SSO
callback with a 500 error. Catch DecodeError and skip JWT-based
extraction gracefully, since user info is already available from
the UserInfo endpoint.
Fixes#20724
