What Tunes is for

Music and podcast questions answered from catalogue data rather than memory: who sings a song and on which album, an album's tracklist and label, an artist's story, top tracks and similar acts, what is charting, what people are actually playing, and where to find a podcast and its latest episodes.

What it does

Deezer's public catalogue: search tracks (artist, album, duration, 30-second preview), albums, artists and public playlists; a track with release date, ISRC, BPM, contributors and explicit flag; an album with label, genres, duration and full tracklist; an artist with fans, top ten tracks and similar artists; a discography newest-first with release types; charts for tracks, albums, artists, playlists and podcasts overall or by genre; podcast search and episodes. TheAudioDB (free tier): biography, origin, formed year, genre, style, label and members. MusicBrainz: canonical identity (type, country, active years, tags). ListenBrainz: site-wide top artists, tracks and albums by listen count for a week, month, year or all time.

What it is not

Tunes never returns lyrics — they are copyrighted; it links to the track's page instead. Previews are Deezer's 30-second clips, not full streams. Charts are Deezer's editorial charts (global); ListenBrainz statistics reflect its own community. Concert dates and ticketing are not covered.

Tools

Catalogue

search_music — Search Deezer's catalogue for tracks (with artist, album, duration, preview), albums, artists or public playlists. Use for "who sings X", "find the album Y", "songs called Z". Args: query, kind, max_results.

track — One track in full: artist, album and its release date, duration, ISRC, BPM, contributors (featured artists), explicit flag, 30-second preview and link. Use for "how long is Bohemian Rhapsody", "what album is Yellow on", "BPM of Blinding Lights". Args: track_id, title, artist.

album — An album with label, release date, genres, total duration, contributors and the full tracklist (with 30-second previews). Use for "tracklist of Abbey Road", "when was Thriller released", "songs on Moon Music". Args: album_id, title, artist.

Artists

artist — An artist's profile: fans and album count on Deezer, biography, origin, formed/born year, genre, style, label and members (TheAudioDB), MusicBrainz identity (type, country, active years, tags), top 10 tracks and similar artists. Use for "tell me about Coldplay", "where is Burna Boy from", "when did Radiohead form". Args: name, artist_id.

discography — An artist's releases newest first: albums, EPs and singles with release dates, track counts and covers. Use for "Coldplay's albums in order", "latest release by Taylor Swift", "how many albums has Radiohead made". Args: name, artist_id, albums_only, max_results.

similar_artists — Artists similar to a given one (Deezer's related-artist graph) with fans and links. Use for "artists like Coldplay", "who else sounds like Billie Eilish". Args: name, max_results.

Popularity

charts — Deezer's current charts: top tracks, albums, artists, playlists or podcasts, overall or for a genre. Use for "top songs right now", "most popular rap tracks", "top albums this week", "biggest podcasts". Args: kind, genre, max_results.

listening_now — What people are actually playing — ListenBrainz's site-wide top artists, tracks or albums by listen count for a period (open data from scrobbles). Use for "what is the world listening to this month", "most played artists this year". Args: entity, period, max_results.

Podcasts

podcast_search — Find podcasts by name or topic: title, description, fans, artwork and link. Use for "find the Lex Fridman podcast", "popular history podcasts". Args: query, max_results.

podcast_episodes — Latest episodes of a podcast: title, date, duration, description and link. Use for "latest episodes of Huberman Lab", "what did Lex Fridman publish this week". Args: podcast_id, name, max_results.

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Tunes — Privacy Policy

Effective 23 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Tunes is. Tunes is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for music and podcast information: search, tracks, albums, artists, discographies, charts, listening statistics, podcasts and episodes. You interact with your assistant; the assistant sends us only the song, album, artist or podcast name, identifier or genre needed for the lookup.

What we receive. The arguments of each tool call (a title, an artist or podcast name, a catalogue id, a genre, a period), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Lookups are forwarded, not stored. Queries are passed to the sources below and the answer is returned to your assistant. We do not record what you listen to or ask about, infer tastes or build a profile. Nothing you send is stored, logged in request bodies or used to train anything. Successful upstream answers are cached in memory for one hour (charts, search) to one day (catalogue records), keyed by the query, to reduce load on the sources.

What we do not receive or store. We do not receive your conversation with the assistant, your name, contacts, streaming-service accounts or listening history. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. Deezer (api.deezer.com), TheAudioDB (theaudiodb.com), MetaBrainz (musicbrainz.org, listenbrainz.org). Each receives the query and our server's IP address, never yours. Preview links returned to your assistant point to Deezer's CDN; opening them is a request from your device to Deezer under Deezer's privacy policy. Hosting: Vercel (United States regions).

Legal bases and your rights. For users in California, the EU/UK and elsewhere, our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Tunes is a general-audience service operated by the adult using the assistant; explicit-content flags are passed through from the catalogue.

Changes. We will post changes here with a new effective date.
