musicbrainz-mcp
An MCP server for MusicBrainz, the open music encyclopedia. It gives Claude live access to MusicBrainz metadata — artists, releases, recordings, labels, works, and more — plus Cover Art Archive images, and (optionally) lets you submit your own tags, ratings, and collection edits.
Developed and maintained by AI (Claude Code). Use at your own discretion.
Tools
Read (no credentials required):
| Tool | What it does |
|---|---|
musicbrainz_search | Search any entity type with a Lucene query; returns ranked matches + MBIDs |
musicbrainz_lookup | Look up an entity by MBID, with inc subqueries for linked data |
musicbrainz_browse | List all entities linked to another (e.g. every release by an artist) |
musicbrainz_cover_art | Cover Art Archive image URLs for a release / release-group |
musicbrainz_resolve | Turn a pasted musicbrainz.org URL into its entity |
musicbrainz_healthcheck | Verify connectivity and whether OAuth writes are configured |
Write (OAuth, confirm-gated):
| Tool | What it does |
|---|---|
musicbrainz_submit_tags | Apply user tags to an entity on your account |
musicbrainz_submit_rating | Set your 0–100 rating for an entity |
musicbrainz_modify_collection | Add/remove entities in one of your collections |
Each write makes no network call without confirm: true; it returns a dry-run preview first.
Install
This is a Node MCP server (stdio). Point your MCP host at it:
{
"mcpServers": {
"musicbrainz": {
"command": "npx",
"args": ["-y", "musicbrainz-mcp"]
}
}
}Reads work immediately. MusicBrainz asks clients to make at most one request per second — the server throttles itself to stay within that limit, so large browses are paced automatically.
Enabling the write tools (optional)
- Register an application at musicbrainz.org/account/applications (redirect URI
urn:ietf:wg:oauth:2.0:oob). - Complete the OAuth flow with the
tag,rating, andcollectionscopes to obtain a refresh token. - Provide these via your MCP host's env (or a local
.env):
MUSICBRAINZ_OAUTH_CLIENT_ID=...
MUSICBRAINZ_OAUTH_CLIENT_SECRET=...
MUSICBRAINZ_OAUTH_REFRESH_TOKEN=...Development
