The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
search_plexSearch for movies, TV shows, and other content in Plex libraries
browse_librariesList all available Plex libraries (Movies, TV Shows, Music, etc.)
browse_libraryBrowse content within a specific Plex library with filtering and sorting options
get_recently_addedGet recently added content from Plex libraries
get_watch_historyGet playback history for the Plex server
get_on_deckGet 'On Deck' items (continue watching) for users
list_playlistsList all playlists on the Plex server
browse_playlistBrowse and view the contents of a specific playlist with full track metadata
create_playlistCreate a new regular playlist on the Plex server. Requires an initial item (item_key parameter) to be created successfully. Smart playlists are not supported due to their complex filter requirements.
add_to_playlistAdd items to an existing playlist
delete_playlistDelete an existing playlist
get_watched_statusCheck watch status and progress for specific content items
get_collectionsList all collections available on the Plex server
browse_collectionBrowse content within a specific collection
get_media_infoGet detailed technical information about media files (codecs, bitrates, file sizes, etc.)
get_library_statsGet comprehensive statistics about Plex libraries (storage usage, file counts, content breakdown, etc.)
get_listening_statsGet detailed listening statistics and music recommendations based on play history and patterns
discover_musicNatural language music discovery with smart recommendations based on your preferences and library
authenticate_plexInitiate Plex OAuth authentication flow to get user login URL
check_auth_statusCheck if Plex authentication is complete and retrieve the auth token
clear_authClear stored authentication credentials
validate_llm_responseValidate LLM response format and content against expected schemas for different prompt types
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
22/22 tools missing one or more hints — search_plex (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); browse_libraries (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); browse_library (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +19 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool test coverage
Only 0/22 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Secrets not written to files
1 secret value written to files
Avoid persisting secrets to disk. Keep them in memory or your secret manager.
Production dependencies are patched
0 critical, 15 high severity in production deps — @modelcontextprotocol/sdk@1.13.0 (high), @modelcontextprotocol/sdk@1.13.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
