Code with Voice Leading Checker

Your agent can call `analyze_voice_conduction` while you're writing code. It checks how notes move between two chord voicings, providing live feedback based on classical harmonic theory. You get the results injected directly into your working context.

Check Musical Integrity in Cursor

You can use `check_voice_hierarchy` to validate that voices stay in correct ascending order, all without leaving your editor. This MCP allows you to treat musical theory checks like any other API call—it generates live, working code using the results.

Test Musical Transitions Live

The `evaluate_smoothness` tool assesses how smooth a musical transition is. When your agent calls this MCP, it gives you real data about harmonic plausibility, letting you debug musical sections right alongside your software code.

Common questions about Voice Leading Checker MCP in Cursor

You add the server to your project's `mcp.json` file, and then enable Agent mode in chat. Your agent can call the tools and inject live data directly into the code you are writing.

Since it's an AI code editor, the MCP results don't just appear in a chat window. The agent generates working code that incorporates real API responses from this server.

No, this specific MCP is built only for musical analysis. It requires chord voicings and harmonic sequences to run its checks. You'll need a different tool if your data isn't music theory related.

The server handles structured musical notation, specifically chord voicings and their transitions. It doesn’t touch any files outside of the data you explicitly pass to it during a coding session.

The tool is built on established classical principles, making it rigorous. However, if your piece uses highly atonal techniques, the system will flag potential discrepancies because its scope assumes standard Western tonality.
