MCP Music Studio

Two-mode creative music studio for AI: scored composition (ABC notation with sheet music) and live performance (Strudel live coding with TidalCycles). Interactive UI renders inline in Claude Desktop, claude.ai, and other MCP clients.

Quick Start — No Install Required

Paste this URL into any MCP client that supports remote servers:

https://mcp-music-studio.linxule.workers.dev/mcp

Claude Desktop / claude.ai: Settings → Connectors → Add Connector → paste the URL above → done.

Claude Code:

claude mcp add --transport http music-studio https://mcp-music-studio.linxule.workers.dev/mcp

That's it — ask Claude to play a song or create a beat.

What You Get

Scored Composition (ABC Notation)

Write sheet music → see it rendered → hear it played with multi-instrument audio.

• 8 style presets — rock, jazz, bossa, waltz, march, reggae, folk, classical — one parameter adds drums + bass + chord accompaniment
• 30 instruments — piano, strings, brass, woodwinds, synths — selectable by name
• Visual sheet music — notes highlight as they play
• Streaming render — sheet music appears as the AI types
• WAV download — export audio as WAV files directly from the UI
• get-music-guide — 7 reference topics (instruments, drums, ABC syntax, arrangements, genres, styles, MIDI directives)

Live Performance (Strudel)

Write code → hear it play → edit in a live REPL.

• TidalCycles mini-notation in JavaScript
• 72 drum machine banks + 128 GM instruments + built-in synths
• Full effects chain — filters, reverb, delay, FM synthesis
• Editable REPL — users can tweak the code and hear changes instantly
• Record & download — capture live audio and export as WAV
• get-strudel-guide — 7 reference topics (mini-notation, sounds, effects, patterns, genres, tips, advanced)

Shared

• search-music-docs — semantic search over strudel.cc and ABCJS documentation

Local Install (Optional)

The remote URL above works without any local setup. If you prefer running locally (offline use, lower latency), install via npm:

CLI One-Liners

# Claude Code
claude mcp add music-studio -- npx -y mcp-music-studio --stdio

# Codex CLI
codex mcp add -- npx -y mcp-music-studio --stdio

# Gemini CLI
gemini mcp add -- npx -y mcp-music-studio --stdio

# OpenCode
opencode mcp add music-studio -- npx -y mcp-music-studio --stdio

JSON Config (Claude Desktop, Cursor, Windsurf, etc.)

{
  "mcpServers": {
    "music-studio": {
      "command": "npx",
      "args": ["-y", "mcp-music-studio", "--stdio"]
    }
  }
}

Add to .vscode/mcp.json — note: uses "servers" not "mcpServers":

{
  "servers": {
    "music-studio": {
      "command": "npx",
      "args": ["-y", "mcp-music-studio", "--stdio"]
    }
  }
}

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "music-studio": {
      "command": "npx",
      "args": ["-y", "mcp-music-studio", "--stdio"]
    }
  }
}

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "music-studio": {
      "command": "npx",
      "args": ["-y", "mcp-music-studio", "--stdio"]
    }
  }
}

On Windows, npx is a .cmd file and requires a shell wrapper:

{
  "mcpServers": {
    "music-studio": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "mcp-music-studio", "--stdio"]
    }
  }
}

The server auto-detects ext-apps support. For clients that don't support it (Cherry Studio, CLI environments), use --render-mode:

{
  "mcpServers": {
    "music-studio": {
      "command": "npx",
      "args": ["-y", "mcp-music-studio", "--stdio", "--render-mode", "browser"]
    }
  }
}

Tools

Development

bun install
bun run dev      # watch + serve (hot reload)
