Cochlea MCP Server

A headless audio engine for agents. Write a score as data, render it offline to deterministic PCM, then listen through numbers - loudness, onsets, pitch, key, spectrograms - and assert what you heard. Compose → render → probe → verify, with no human ear (and no audio device) in the loop.

People who need browser automation tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.
