MCP Server for Ableton Live

Ableton Live MCP Server

📌 Overview

The Ableton Live MCP Server is a server implementing the Model Context Protocol (MCP) to facilitate communication between LLMs and Ableton Live. It uses OSC (Open Sound Control) to send and receive messages to/from Ableton Live. It is based on AbletonOSC implementation and exhaustively maps available OSC adresses to tools accessible to MCP clients.

This project consists of two main components:

• mcp_ableton_server.py: The MCP server handling the communication between clients and the OSC daemon.
• osc_daemon.py: The OSC daemon responsible for relaying commands to Ableton Live and processing responses.

✨ Features

• Provides an MCP-compatible API for controlling Ableton Live from MCP clients.
• Uses python-osc for sending and receiving OSC messages.
• Based on the OSC implementation from AbletonOSC.
• Implements request-response handling for Ableton Live commands.

⚡ Installation

Option 1: Install with UV (Recommended)

1. Install UV if you don't have it already:

   pip install uv
   

2. Install directly from PyPI:

   uv install ableton-live-mcp-server
   

3. Or install from GitHub:

   uv install git+https://github.com/mrmos/ableton-live-mcp-server.git
   

Option 2: Manual Installation

1. Install uv

   pip install uv
   

2. Clone the repository:

   git clone https://github.com/your-username/mcp_ableton_server.git
   cd mcp_ableton_server
   

3. Install dependencies:

   uv install python-osc fastmcp
   

4. Install the MCP Server This assumes that you're using Claude Desktop

   mcp install mcp_ableton_server.py
   

5. Install AbletonOSC Follow the instructions at AbletonOSC

🚀 Usage

Running with a Single Command (Recommended)

The easiest way to start the Ableton Live MCP Server is with the included launcher script:

# Basic usage (runs both components with default settings)
ableton-mcp-start

# Show debug output from both components
ableton-mcp-start --debug

# Customize ports if needed
ableton-mcp-start --osc-port 65432 --mcp-port 8000 --ableton-port 11000 --receive-port 11001

The launcher automatically:

1. Starts the OSC daemon first
2. Verifies that it's running properly
3. Starts the MCP server
4. Monitors both processes and shuts them down gracefully on exit

Manual Starting (Advanced)

Alternatively, you can manually start each component in separate terminal windows:

Step 1: Run the OSC Daemon

First, start the OSC daemon to handle OSC communication between the MCP server and Ableton Live:

ableton-osc-daemon

This will:

• Listen for MCP client connections on port 65432.
• Forward messages to Ableton Live via OSC on port 11000.
• Receive OSC responses from Ableton on port 11001.

Step 2: Run the MCP Server

In a separate terminal window, start the MCP server to enable LLMs to control Ableton:

ableton-mcp-server

Example Usage

In Claude desktop, ask Claude: Prepare a set to record a rock band Set the input routing channel of all tracks that have "voice" in their name to Ext. In 2

⚙️ Configuration

By default, the server and daemon run on localhost (127.0.0.1) with the following ports:

• MCP Server Socket: 65432
• Ableton Live OSC Port (Send): 11000
• Ableton Live OSC Port (Receive): 11001

To modify these, edit the AbletonOSCDaemon class in osc_daemon.py or use command-line parameters:

ableton-osc-daemon --socket-port 65432 --ableton-port 11000 --receive-port 11001

Claude Desktop Configuration

To configure Claude Desktop to use Ableton Live MCP Server:

1. Edit the Claude Desktop configuration file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%/Claude/claude_desktop_config.json

2. Add the following to your configuration:

"mcpServers": {
  "Ableton Live Controller": {
    "command": "ableton-mcp-start",
    "args": []
  }
}

3. For debugging with visible output:

"mcpServers": {
  "Ableton Live Controller": {
    "command": "ableton-mcp-start",
    "args": ["--debug"]
  }
}

4. Restart Claude Desktop
