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 ~322
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 (a private collection needs OAuth: MUSICBRAINZ_OAUTH_*), 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"… |
No output schema declared.
No examples provided.
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 ~293
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. Your own tags/ratings (inc: ["user-tags"], ["user-ratings"], …) need OAuth (MUSICBRAINZ_OAUTH_*). 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"… |
No output schema declared.

musicbrainz_modify_collection Add or remove entities in a MusicBrainz collection ~301
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>). Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). Nothing is changed before confirmation. 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 |
| confirmToken | string | – | ONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has se… |
| entityType | string | yes | Plural entity type the collection holds (e.g. "releases") |
| mbids | array | yes | MBIDs of the entities to add/remove |
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 |
| 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"… |
No output schema declared.
No examples provided.
musicbrainz_search Search MusicBrainz ~271
Search a MusicBrainz entity type with a Lucene query and get back ranked matches with their MBIDs. Plain text matches the entity name; fielded Lucene also works, e.g. `artist:"Miles Davis" AND country:US`, `release:"Kind of Blue" AND format:Vinyl`, or `recording:"So What" AND dur:[540000 TO 560000]`. Feed a returned MBID into musicbrainz_lookup for full detail. Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.
| Name | Type | Req | Description |
|---|---|---|---|
| entity | string | yes | Entity type to search |
| limit | integer | – | Max results (1–100, default 25) |
| offset | integer | – | Result offset for paging (default 0) |
| query | string | yes | Lucene query string (plain text or fielded) |
| 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"… |
No output schema declared.
No examples provided.
musicbrainz_submit_rating Submit a user rating to MusicBrainz ~278
Set YOUR rating for a MusicBrainz entity (needs OAuth: MUSICBRAINZ_OAUTH_* with the `rating` scope). Rating is 0–100 (MusicBrainz shows it as 1–5 stars in steps of 20; 0 removes your rating). Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). Nothing is sent before confirmation. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.
| Name | Type | Req | Description |
|---|---|---|---|
| confirmToken | string | – | ONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has se… |
| entity | string | yes | Entity type to rate |
| mbid | string | yes | MBID of the entity to rate |
| rating | integer | yes | Rating 0–100 (0 removes; 20/40/60/80/100 = 1–5 stars) |
No output schema declared.
No examples provided.
musicbrainz_submit_tags Submit user tags to MusicBrainz ~276
Apply user tags to a MusicBrainz entity on YOUR account (needs OAuth: MUSICBRAINZ_OAUTH_* with the `tag` scope). Default `vote: upvote` adds the tags; `downvote` opposes them; `withdraw` removes your vote. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). The preview shows the exact XML; nothing is sent before confirmation. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.
| Name | Type | Req | Description |
|---|---|---|---|
| confirmToken | string | – | ONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has se… |
