Ableton MCP Server

Control Ableton Live with AI through natural conversation.

An MCP (Model Context Protocol) server that exposes 260+ tools for controlling Ableton Live from Claude Code. Create tracks, manipulate MIDI, load instruments, and produce music—all through natural language.

Quick Start

# 1. Clone and install
git clone https://github.com/ldraney/ableton-mcp.git
cd ableton-mcp
poetry install

# 2. Start Ableton Live 12 with AbletonOSC enabled

# 3. Start Claude Code in this directory
claude

# 4. Just ask for what you want!

That's it. Claude reads the project documentation and knows how to guide you through creating music. Try:

• "Create a lo-fi beat"
• "Make a simple drum pattern"
• "Help me set up audio export"

Why This Exists

Traditional DAW workflows require clicking through menus and dialogs. This project lets you describe what you want in plain English:

"Create a MIDI track, load a drum kit, and add a four-on-the-floor kick pattern at 120 BPM"

Claude Code executes the sequence of operations in Ableton while you watch it happen in real-time.

Features

Comprehensive Control

• 80+ Song Tools - Transport, tempo, time signature, loop regions, cue points, recording
• 70+ Track Tools - Volume, pan, mute/solo, routing, sends, device management
• 50+ Clip Tools - MIDI note manipulation, audio warping, launch modes, loop settings
• 40+ Device Tools - Parameter control, enable/disable, MIDI mapping
• 20+ Browser Tools - Search instruments, load presets, explore packs

Key Capabilities

• Full transport control (play, stop, record, loop)
• Create and delete MIDI/audio tracks
• Add, edit, and remove MIDI notes programmatically
• Load any Ableton instrument, effect, or preset by name
• Control device parameters in real-time
• Navigate session view (select tracks, scenes, clips)
• Query song state (tempo, time signature, track counts)

Quick Example

Once configured, you can have conversations like:

You: Create a simple beat Claude: Creates MIDI track → Loads 808 Core Kit → Adds kick on 1 and 3, snare on 2 and 4 → Sets tempo to 90 BPM → Hits play

Behind the scenes, Claude calls tools like:

song_set_tempo(bpm=90)
song_create_midi_track(index=0)
track_set_name(track_index=0, name="Drums")
track_insert_device(track_index=0, device_name="808 Core Kit")
clip_slot_create_clip(track_index=0, scene_index=0, length=4)
clip_add_notes(track_index=0, clip_index=0, notes=[
    {"pitch": 36, "start_time": 0, "duration": 0.5, "velocity": 100},  # Kick
    {"pitch": 38, "start_time": 1, "duration": 0.5, "velocity": 100},  # Snare
    {"pitch": 36, "start_time": 2, "duration": 0.5, "velocity": 100},  # Kick
    {"pitch": 38, "start_time": 3, "duration": 0.5, "velocity": 100},  # Snare
])
clip_fire(track_index=0, clip_index=0)

Prerequisites

• Python 3.11+
• Ableton Live 12 with AbletonOSC installed and enabled
• Claude Code (or any MCP-compatible client)

Installation

# Clone the repository
git clone https://github.com/ldraney/ableton-mcp.git
cd ableton-mcp

# Install with Poetry
poetry install

Configuration

Add to your Claude Code MCP settings (~/.claude/settings.json or project .mcp.json):

{
  "mcpServers": {
    "ableton": {
      "command": "poetry",
      "args": ["run", "ableton-mcp"],
      "cwd": "/path/to/ableton-mcp"
    }
  }
}

WSL2 Support

The server auto-detects WSL2 environments and configures the correct Windows host IP. No manual configuration needed.
