Music Recognition API, CLI and MCP Server

Identify songs and read BPM, musical key and Camelot codes from your terminal, from an MCP client, or straight from your own code. Free, no API key, open source.

Command line

Identify a track and read its tempo and key without leaving the terminal. Also a fully typed client library with zero runtime dependencies.

npm i -g songfinder

MCP server

Four tools for Claude, Cursor, Windsurf and Zed. Ask what a song is, then ask for its BPM, key and harmonically compatible tracks.

npx -y songfinder-mcp

Agent Skills

Claude Code skills that need nothing installed beyond curl. Identify songs and build beatmatched set lists in conversation.

One command, the whole analysis

What the API gives you

The same endpoints that power this site, open to any client.

Recognition

From a YouTube, TikTok, Instagram, SoundCloud, Bilibili or X link, from any direct media URL, or from an audio file. A chain of engines runs in order until one matches.

Acoustic analysis

Tempo, musical key with its Camelot wheel position and compatible keys, plus energy, danceability, valence, acousticness, instrumentalness, liveness, speechiness and loudness.

Neighbour search

Tracks that sound like a given one, optionally restricted to keys that mix cleanly with it — what you want when the output is a DJ set rather than a list.

No API key, no account

No signup and no rate card. Song Finder runs recognition through its own self-deployed API and rate-limits requests per IP to keep the service stable; analysis endpoints allow roughly one call every one to five seconds.

Open source

All three clients are MIT licensed and developed in the open. Issues and pull requests are welcome on any repository.
