Common questions about Chord Substitution Finder MCP in Claude Desktop

It functions as an MCP, letting your agent call specific music theory tools directly. You give it a progression or a chord, and the tool executes the analysis using zero-trust methods inside Vinkius. The result pops right into your chat for you to review.

The MCP focuses on harmonic structure, not tempo. However, by using `analyze_progression_tension`, you can see how the inherent tension of a chord progression might change if you shift the emotional weight or rhythm.

This MCP handles musical theory and harmonic data. Specifically, it processes chord names, functional harmony relationships (like ii-V), and related substitutions.

Yeah, the tools are designed for complex analysis. You can input standard diatonic chords or more ambiguous jazz voicings; the system will analyze the structure regardless.

Start by analyzing a section with `analyze_progression_tension` to pinpoint the weak spots. Then, run `find_substitutions` on those chords and finally, use `get_substitution_detail` to vet the best option.
