🟢musicbrainz_search_entities(entityType, query, limit, offset)
Full-text search across a MusicBrainz entity type (artist, release-group, release, recording, work, label) using a Lucene query string. Returns ranked matches with MBID, name/title, disambiguation, type, and a 0–100 relevance score (100 = exact). Starting point when resolving a name to an MBID — chain the returned MBID into the matching musicbrainz_get_* tool. Results are in MusicBrainz score-descending order. Supports field-scoped Lucene syntax (e.g. `artist:radiohead AND country:GB`).

}🟢musicbrainz_get_artist(mbid, inc_release_groups, inc_relationships)
Artist profile by MBID: type (person/group/…), country, life span, gender, area, aliases, tags/genres, plus the discography (release-groups) and band-membership / collaboration relationships and external links (Wikidata QID, Discogs, official site — surfaced as url-rels chainable to those servers). The 80% artist-detail call. Discography and relationships are capped at one page (25); for a prolific artist's complete release-group list, call musicbrainz_browse_entities with target_type=release-group and the artist link.

}🟢musicbrainz_get_recording(mbid, inc_relationships)
Recording (a specific performance/track, distinct from the abstract work) by MBID: length, artist credits, ISRCs, the releases it appears on, the work(s) it performs (work-rels — chain to musicbrainz_get_work), and performance/production relationships (who played, produced, engineered, conducted — each with the role and the credited artist MBID). Relationships are capped at one page; for a heavily-covered recording call musicbrainz_browse_entities with target_type=recording and link.work.

}🟢musicbrainz_lookup_identifier(id_type, value)
Resolve a standard identifier to MusicBrainz entities without a name search — the deterministic path when you already hold an ID. id_type=isrc → recordings (a recording-level code, often shared by several recordings); id_type=iswc → works (a composition-level code); id_type=barcode → releases (UPC/EAN digits; spaces and hyphens are ignored). ISRC and ISWC hit dedicated exact endpoints; barcode is a Lucene search filter so results are ranked (exact match scores 100). The output kind field tells you which entity type came back.

}🟢musicbrainz_browse_entities(target_type, link, limit, offset)
Paginate the COMPLETE set of entities linked to a parent MBID — every release-group by an artist, every release on a label, every recording of a work, every release in a release-group. This is the only complete-enumeration path: the get_* tools embed at most one page (25) of any linked list, so use this tool whenever a linked set may exceed a page (a prolific artist, a major label with thousands of releases, a heavily-covered work). Provide exactly ONE link MBID matching a valid parent→child relationship for the target_type. Pages arbitrarily deep via offset; totalCount is the true upstream total.

}🟢musicbrainz_get_cover_art(mbid, entity_type)
Cover Art Archive images for a release or release-group MBID: front/back flags, image types, full-resolution URLs, and 250/500/1200px thumbnail URLs. Returns an empty image set (NOT an error) when the entity has no art — absence of art is information. An MBID that matches no release or release-group of the given entity_type fails with entity_not_found instead of an empty set. Art is served at the release level; a release-group MBID resolves to a representative release's art automatically. URLs are linked, never rehosted — image copyright stays with the rights holders (only MusicBrainz core metadata is CC0).
