The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
musicbrainz_browse Browse MusicBrainz entities linked to another ~308
List all entities of one type directly linked to a given entity — e.g. every release by an artist (entity: "release", linkedBy: "artist", mbid: <artist>), recordings on a release, releases in a collection, or events at a place. This is the complete, paged set for a relationship (unlike search, which ranks fuzzy matches). Use `inc` for extra detail and limit/offset to page (max 100/page). Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.
| Name | Type | Req | Description |
|---|---|---|---|
| entity | string | yes | Result entity type to list |
| inc | array | – | Subqueries to include, e.g. ["labels","recordings"] |
| limit | integer | – | Max results (1–100, default 25) |
| linkedBy | string | yes | The relationship to browse by (the linking entity type) |
| mbid | string | yes | MBID of the linking entity |
| offset | integer | – | Result offset for paging (default 0) |
| view | string | – | Response shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full"… |

musicbrainz_cover_art Get Cover Art Archive images for a release ~119
Fetch Cover Art Archive image metadata for a release or release-group MBID — front/back cover URLs, thumbnails, and image types. Returns the image URLs (you can open or download them); it does not embed the bytes. Errors clearly when no art exists for the MBID. Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.
| Name | Type | Req | Description |
|---|---|---|---|
| entity | string | yes | Which MBID type the cover art is keyed on |
| mbid | string | yes | Release or release-group MBID |
No output schema declared.
No examples provided.
musicbrainz_healthcheck Verify MusicBrainz connectivity ~62
Confirm the MusicBrainz API is reachable (and our User-Agent accepted) by looking up a stable entity, and report whether the OAuth write path is configured. Reports {ok, reachable, oauth_configured} with a plain-English hint. Read-only.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
musicbrainz_lookup Look up a MusicBrainz entity by MBID ~262
Fetch a single MusicBrainz entity (artist, release, recording, release-group, label, work, area, place, event, instrument, series, genre, url) by its MBID. Use `inc` to pull linked sub-entities and relationships, e.g. inc: ["releases","release-groups"] on an artist, or ["recordings","labels"] on a release, or ["artist-credits","url-rels"] on most entities. Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.
| Name | Type | Req | Description |
|---|---|---|---|
| entity | string | yes | Entity type to look up |
| inc | array | – | Subqueries/relationships to include, e.g. ["releases","url-rels","tags"] |
| mbid | string | yes | The entity MBID (UUID) |
| view | string | – | Response shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full"… |

musicbrainz_modify_collection Add or remove entities in a MusicBrainz collection ~213
Add or remove entities (releases, artists, recordings, release-groups, works, labels, places, areas, events) in one of YOUR MusicBrainz collections (needs OAuth: MUSICBRAINZ_OAUTH_* with the `collection` scope). Get the collection MBID from its URL (musicbrainz.org/collection/<mbid>). Without confirm: true it returns a dry-run preview and makes NO network call; with confirm: true it applies the change. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | Whether to add to or remove from the collection |
| collection | string | yes | MBID of the target collection |

No output schema declared.
No examples provided.
musicbrainz_resolve Resolve a MusicBrainz URL to its entity ~224
Turn a musicbrainz.org URL (e.g. https://musicbrainz.org/artist/<mbid> or /release-group/<mbid>) into the underlying entity by extracting its type + MBID and looking it up. Handy when a user pastes a MusicBrainz link. Pass `inc` to include linked sub-entities. Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.
| Name | Type | Req | Description |
|---|---|---|---|
| inc | array | – | Subqueries to include on the resolved entity |
| url | string | yes | A musicbrainz.org entity URL or an "entity/mbid" path |
