FreqBlog Music Metadata MCP MCP server

An official hosted MCP server by FreqBlog that provides audio features, BPM, key, mood, and genre data for music tracks. It serves as a replacement for Spotify's audio_features API, allowing AI agents to query tracks by name or ISRC without requiring Spotify IDs, supporting tasks like harmonic set-building and track analysis.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http freqblog-music-metadata-mcp https://mcp.freqblog.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add freqblog-music-metadata-mcp --url https://mcp.freqblog.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable freqblog-music-metadata-mcp in your MCP settings.
