No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
The render endpoint returns three output formats in a single response: inline SVG, MusicXML, and MIDI. The Harmonic Analyzer provides measure-accurate analysis, including Roman numerals and key detection, and flags bare textures as advisory. The knowledge search endpoint performs semantic search over a hand-curated music-theory corpus to help agents ground their output.
Summary drafted from the project's own website. Every sentence is backed by text on that page and was reviewed before publishing.
