FreqBlog Music Metadata is a Model Context Protocol (MCP) server: Audio features + harmonic set-building for tracks by name/ISRC. Spotify audio-features replacement. In practice that means any MCP-compatible AI assistant can call FreqBlog Music Metadata's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://mcp.freqblog.com/mcp and you're connected, with nothing to install locally. The current release is v1.1.0.
FreqBlog Music Metadata is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
