ableton-mcp-extended 2.2.0

Extended Ableton Live integration with 76 tools through the Model Context Protocol

AbletonMCP Extended - Ableton Live Model Context Protocol Integration

76 tools for comprehensive Ableton Live control

AbletonMCP Extended connects Ableton Live to Claude AI through the Model Context Protocol (MCP), allowing Claude to directly interact with and control Ableton Live. This extended version includes 76 tools for comprehensive music production, track creation, arrangement manipulation, and Live session control.

Based on the original ableton-mcp by Siddharth Ahuja, with 56 additional tools for professional workflows.

Features

• Two-way communication: Connect Claude AI to Ableton Live through a socket-based server
• Track manipulation: Create, modify, and manipulate MIDI and audio tracks
• Instrument and effect selection: Claude can access and load the right instruments, effects and sounds from Ableton's library
• Clip creation: Create and edit MIDI clips with notes
• Session control: Start and stop playback, fire clips, and control transport
• Arrangement recording: Arm tracks and record into arrangement view with overdub support
• Audio sample loading: Load audio files and samples into clip slots from Ableton's browser
• Audio warping: Control warp modes, enable/disable warping, and manipulate audio time-stretching
• Audio clip manipulation: Crop and reverse audio clips for creative sound design
• Audio analysis: Comprehensive analysis including BPM detection, transient detection, frequency content, and waveform descriptions
• Audio-to-MIDI transcription: Analyze audio files and transcribe them to MIDI with tempo, key, and note detection (powered by audio2llm)
• Track freezing and export: Freeze tracks to render audio, enabling CPU-efficient playback and audio extraction workflows

Components

The system consists of two main components:

1. Ableton Remote Script (Ableton_Remote_Script/__init__.py): A MIDI Remote Script for Ableton Live that creates a socket server to receive and execute commands
2. MCP Server (server.py): A Python server that implements the Model Context Protocol and connects to the Ableton Remote Script

Installation

Quick Install

Install via pip/uvx:

uvx ableton-mcp-extended

Optional: Enhanced Audio-to-MIDI Transcription

For significantly better polyphonic audio transcription (detecting chords, multiple instruments simultaneously), install basic-pitch:

pip install basic-pitch

Why install this?

• Without basic-pitch: Monophonic transcription (one note at a time) - works for simple melodies
• With basic-pitch: Polyphonic transcription (multiple simultaneous notes) - works for chords, complex arrangements, and full mixes

The analyze_audio_file tool will automatically use the best available transcription method. Basic Pitch provides professional-grade transcription powered by Spotify's ML model.

Workflow with audio2llm:

1. Provide Claude with any WAV/MP3 audio file path
2. Claude analyzes it and extracts: tempo, key, and musical notes
3. Claude can recreate the audio as MIDI in Ableton or generate complementary parts
4. Perfect for sampling, remixing, or learning from reference tracks

Prerequisites

• Ableton Live 10 or newer
• Python 3.8 or newer
• uv package manager

If you're on Mac, please install uv as:

brew install uv

Otherwise, install from [uv's official website][https://docs.astral.sh/uv/getting-started/installation/]

⚠️ Do not proceed before installing UV

Claude for Desktop Integration

Follow along with the setup instructions video

1. Go to Claude > Settings > Developer > Edit Config > claude_desktop_config.json to include the following:

{
    "mcpServers": {
        "AbletonMCP": {
            "command": "uvx",
            "args": [
                "ableton-mcp-extended"
            ]
        }
    }
}

Cursor Integration

Run ableton-mcp-extended without installing it permanently through uvx. Go to Cursor Settings > MCP and paste this as a command:

uvx ableton-mcp-extended

⚠️ Only run one instance of the MCP server (either on Cursor or Claude Desktop), not both

Installing the Ableton Remote Script

Follow along with the setup instructions video

1. Download the AbletonMCP_Remote_Script/__init__.py file from this repo

2. Copy the folder to Ableton's MIDI Remote Scripts directory. Different OS and versions have different locations. One of these should work, you might have to look:

   For macOS:

   • Method 1: Go to Applications > Right-click on Ableton Live app → Show Package Contents → Navigate to: Contents/App-Resources/MIDI Remote Scripts/
   • Method 2: If it's not there in the first method, use the direct path (replace XX with your version number): /Users/[Username]/Library/Preferences/Ableton/Live XX/User Remote Scripts

   For Windows:

   • Method 1: C:\Users[Username]\AppData\Roaming\Ableton\Live x.x.x\Preferences\User Remote Scripts
   • Method 2: C:\ProgramData\Ableton\Live XX\Resources\MIDI Remote Scripts\
   • Method 3: C:\Program Files\Ableton\Live XX\Resources\MIDI Remote Scripts\ Note: Replace XX with your Ableton version number (e.g., 10, 11, 12)

3. Create a folder called 'AbletonMCP' in the Remote Scripts directory and paste the downloaded '__init__.py' file

4. Launch Ableton Live

5. Go to Settings/Preferences → Link, Tempo & MIDI

6. In the Control Surface dropdown, select "AbletonMCP"

7. Set Input and Output to "None"

Usage

Starting the Connection

1. Ensure the Ableton Remote Script is loaded in Ableton Live
2. Make sure the MCP server is configured in Claude Desktop or Cursor
3. The connection should be established automatically when you interact with Claude

Using with Claude

Once the config file has been set on Claude, and the remote script is running in Ableton, you will see a hammer icon with tools for the Ableton MCP.

Technical Details

Communication Protocol

The system uses a simple JSON-based protocol over TCP sockets:

• Commands are sent as JSON objects with a type and optional params
• Responses are JSON objects with a status and result or message

Limitations & Security Considerations

• Creating complex musical arrangements might need to be broken down into smaller steps
• The tool is designed to work with Ableton's default devices and browser items
• Always save your work before extensive experimentation
