MCP server for the [SonoVault](https://sonovault.now) music metadata API. Gives Claude, Cursor, and any MCP client search across 93M+ tracks, artists, labels, and releases, with full metadata per result: genre, label, release dates, artist credits, ISRC and ISWC codes, and cross-platform IDs (Spotify, Apple Music, Tidal, Beatport, Discogs, MusicBrainz, YouTube).
Ask your assistant things like:
- "What releases did mau5trap put out this year?"
- "Find Daft Punk's Veridis Quo and give me its genre, label, and ISRC"
- "Show me the tracklist of Discovery with ISRCs"
- "What's the Spotify and Beatport ID for ISRC GBDUW0000053?"
- "Resolve this play log to ISRCs and labels" (paste up to 100 lines)
- "List every recording of ISWC T-071.020.439-9"
Setup
You need a SonoVault API key. The free tier is 1,000 requests/month, no credit card: get a key.
