Musicbrainz Mcp

chrischall/musicbrainz-mcp

Connects Claude to the MusicBrainz open music encyclopedia via their public API. Read operations need no credentials: search entities with Lucene queries, look up MBIDs with subquery includes, browse linked entities (like all releases for an artist), and fetch Cover Art Archive URLs. Write operations require OAuth and are confirm-gated: submit tags, set ratings, and modify collections on your MusicBrainz account. The server respects MusicBrainz's one request per second rate limit automatically. Useful when you need structured music metadata, discography research, or want to manage your MusicBrainz data through conversation rather than the web UI.
