Music Theory Mcp

This is a local music theory engine that runs without external APIs. It gives Claude tools to generate scales and chords, analyze progressions, detect keys from note sequences, and match musical characteristics to genres. You'd reach for it when building composition assistants, practice tools, or anything that needs to reason about musical structure. Since it's all local computation, there's no rate limiting or auth setup. The operations are straightforward: ask for a scale in a key, get chord voicings, identify what key a melody is in, or query which genres typically use specific progressions or harmonic patterns.
