AniList

Implements the Model Context Protocol (MCP) as a middleware layer between client applications (like Claude Desktop) and the AniList GraphQL API. The server uses a tool registration framework that organizes 40+ tools into nine categories (Search, Media, User, People, Lists, Activity, Thread, Recommendation, Misc), with each tool mapping to specific AniList API endpoints. Client requests flow through StdioServerTransport for message handling, then dispatch to appropriate tool handlers that construct and execute GraphQL queries against AniList's backend.

Exposes search_anime and search_manga tools that query AniList's GraphQL API with support for filtering by title, genre, status, season, year, and other metadata fields. The tools accept search parameters and return paginated results with media details (title, description, ratings, genres, studios). Implements pagination through offset/limit parameters to handle large result sets efficiently.

Implements get_anime and get_manga tools that fetch comprehensive media details from AniList by ID or title, returning structured data including synopsis, genres, studios, staff, characters, relations (sequels/prequels), recommendations, and user statistics. Uses AniList's GraphQL API to construct queries that retrieve nested relationship data in a single request, avoiding N+1 query problems.

Provides get_user_profile, get_user_anime_list, get_user_manga_list, and update_list_entry tools that interact with user-specific AniList data. Authentication is handled via optional ANILIST_TOKEN environment variable; authenticated operations allow users to view private lists and update their own entries (scores, status, progress). Unauthenticated requests return public profile data only. List queries support filtering by status (CURRENT, COMPLETED, PAUSED, DROPPED, PLANNING) and sorting.

Exposes get_character and get_staff tools that fetch detailed information about anime/manga characters and production staff from AniList. Returns structured data including character descriptions, voice actors, media appearances, and staff roles (director, composer, writer, etc.). Queries use AniList's GraphQL API to retrieve nested relationships (e.g., voice actors for a character, works by a staff member) in a single request.

Implements get_recommendation and get_recommendations_for_media tools that retrieve AniList's recommendation engine results. The tools query recommendations based on media ID or user preferences, returning ranked suggestions with reasoning (e.g., 'similar genres', 'same studio'). Uses AniList's GraphQL API to fetch recommendation metadata including recommendation count and user ratings of recommendations.

Exposes get_activity and post_text_activity tools that retrieve user activities (watch/read updates, list changes) and allow authenticated users to post text-based activities. Activities are fetched from AniList's activity feed, showing what users have recently watched, rated, or commented on. Posting requires ANILIST_TOKEN authentication and creates new activity entries visible to the user's followers.

Exposes get_thread and get_thread_comments tools that fetch AniList forum threads and their associated comments. Threads are retrieved by ID and return metadata (title, body, author, creation date, reply count). Comments are paginated and include user information, timestamps, and nested reply structure. Uses AniList's GraphQL API to fetch thread data with optional comment pagination.

Implements update_list_entry tool that modifies user anime/manga list entries with support for updating score, progress (episodes/chapters watched), and status (CURRENT, COMPLETED, PAUSED, DROPPED, PLANNING). Requires ANILIST_TOKEN authentication. The tool constructs GraphQL mutations to update individual list entries, with validation of input parameters before submission to AniList API.

Exposes get_genres and get_studio tools that retrieve metadata about anime/manga genres and production studios. get_genres returns a list of all available genres on AniList with optional filtering. get_studio fetches detailed studio information including their produced media, founding year, and country. Uses AniList's GraphQL API to query static metadata and studio-specific media catalogs.
