live-coding-music-mcp

🎵 MCP server for AI-assisted live-coding music via strudel.cc

Unofficial fan project. Not affiliated with, or endorsed by, the Strudel project. This adapter exists to make live-coding music accessible to beginners who want to try pattern-based music without learning the whole ecosystem first.

Status: Beta | 77% test coverage | Published to npm | Actively developed

A Model Context Protocol (MCP) server that drives Strudel.cc from Claude for AI-assisted live-coding music, pattern generation, and algorithmic composition.

Current State: Beta. The core workflow (init → generate → write → play → analyze) works reliably with real audio output and has 1470 passing tests covering 77% of statements. CI is hardened with OpenSSF Scorecard, SHA-pinned actions, CODEOWNERS, and Dependabot. Known coverage gaps exist (notably AudioCaptureService at 33% and AudioAnalyzer branch coverage at 48%) — see open issues for the full list.

What "Beta" means here:

• Tool schemas are stable within minor versions; breaking changes require a major bump
• Single-browser-session limitation (multi-session tracked in #108)
• Upstream @strudel/* dependencies pinned to known-good versions; Dependabot bumps gated on CI
• Expect hands-on iteration for non-standard patterns — report rough edges, they get fixed
