AbletonMCP-U - Ableton Live Model Context Protocol Integration (Upgraded)

AbletonMCP-U connects Ableton Live to Claude AI through the Model Context Protocol (MCP), allowing Claude to directly interact with and control Ableton Live. This is an upgraded version of the original AbletonMCP project, featuring enhanced functionality and improved stability. This integration enables prompt-assisted music production, track creation, and Live session manipulation.

Note: This project has been updated to be compatible with various versions of the MCP library, fixing initialization issues that could cause crashes.

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
• Enhanced MIDI analysis and arrangement: Read, clear, and replace MIDI notes in clips
• Clip inspection: Get detailed information about clips
• Track enumeration: Get comprehensive lists of tracks with detailed information
• Mix controls: Set track volume and pan
• Device management: Get device lists, parameters, and set parameter values
• Locator management: Create, get, and delete cue points (locators)

Components

The system consists of two main components:

1. Ableton Remote Script (AbletonMCP_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

Installing via Smithery

To install Ableton Live Integration for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @AhmadMagdi/ableton-mcp-u --client claude

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-U": {
            "command": "uvx",
            "args": [
                "ableton-mcp-u"
            ]
        }
    }
}

Cursor Integration

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

uvx ableton-mcp-u

⚠️ 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.

Capabilities

• Get session and track information
• Create and modify MIDI and audio tracks
• Create, edit, and trigger clips
• Control playback
• Load instruments and effects from Ableton's browser
• Add notes to MIDI clips
• Change tempo and other session parameters
• NEW: Read MIDI notes from clips
• NEW: Clear/replace MIDI notes in clips
• NEW: Inspect clip properties
• NEW: Enumerate tracks reliably
• NEW: Mix controls (volume, pan)
• NEW: Device parameter control
• NEW: Locator management using cue points

Example Commands

Here are some examples of what you can ask Claude to do:

• "Create an 80s synthwave track" Demo
• "Create a Metro Boomin style hip-hop beat"
• "Create a new MIDI track with a synth bass instrument"
• "Add reverb to my drums"
• "Create a 4-bar MIDI clip with a simple melody"
• "Get information about the current Ableton session"
• "Load a 808 drum rack into the selected track"
• "Add a jazz chord progression to the clip in track 1"
• "Set the tempo to 120 BPM"
• "Play the clip in track 2"
• "Read the MIDI notes from the clip in track 1, slot 0"
• "Replace the notes in the clip in track 1, slot 0 with a new melody"
• "Get a list of all tracks in the session"
• "Set the volume of track 2 to 0.75"
• "Set the pan of track 1 to center (0.0)"

Troubleshooting

• Connection issues: Make sure the Ableton Remote Script is loaded, and the MCP server is configured on Claude
• Timeout errors: Try simplifying your requests or breaking them into smaller steps
• Have you tried turning it off and on again?: If you're still having connection errors, try restarting both Claude and Ableton Live

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
