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

⚡ Installation

Requirements

Python 3.8+
python-osc (for OSC communication)
fastmcp (for MCP support)
uv (recommended Python package installer)
AbletonOSC as a control surface

Installation Steps

Install uv (https://docs.astral.sh/uv/getting-started/installation):
```
curl -LsSf https://astral.sh/uv/install.sh | sh
```

Clone the repository:

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

Install the project and its dependencies:
```
uv sync
```
Install AbletonOSC Follow the instructions at AbletonOSC

🚀 Usage

Running the OSC Daemon

The OSC daemon will handle OSC communication between the MCP server and Ableton Live:

uv run osc_daemon.py

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.

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:

self.socket_host = '127.0.0.1'
self.socket_port = 65432
self.ableton_host = '127.0.0.1'
self.ableton_port = 11000
self.receive_port = 11001

Claude Desktop Configuration

To use this server with Claude Desktop, you need to configure it in your Claude Desktop settings. The configuration file location varies by operating system:

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

Add the following configuration to your mcpServers section:

{
  "mcpServers": {
    "Ableton Live Controller": {
      "command": "/path/to/your/project/.venv/bin/python",
      "args": ["/path/to/your/project/mcp_ableton_server.py"]
    }
  }

This configuration ensures that:

The server runs with all dependencies properly managed
The project remains portable and reproducible
