Returns: Clean text content from top search results. Query tips: describe the ideal page, not keywords. "blog post comparing React and Vue performance" not "React vs Vue". Use category:people / category:company to search through Linkedin profiles / companies respectively. If highlights are insufficient, follow up with web_fetch_exa on the best URLs.
  • web_fetch_exaRead a webpage's full content as clean markdown. Use after web_search_exa when highlights are insufficient or to read any URL. Best for: Extracting full content from known URLs. Batch multiple URLs in one call. Returns: Clean text content and metadata from the page(s).

Musicbrainz MCP tools 9

  • musicbrainz_lookupFetch 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.
  • musicbrainz_searchSearch 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.
  • musicbrainz_browseList 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.
  • musicbrainz_cover_artFetch 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.
  • musicbrainz_resolveTurn 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.
  • musicbrainz_healthcheckConfirm 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.
  • musicbrainz_submit_tagsApply 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.
  • musicbrainz_submit_ratingSet 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.
  • musicbrainz_modify_collectionAdd 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.
