What is Ableton Live Mcp Server

The Ableton Live MCP Server is a server that implements the Model Context Protocol (MCP) to facilitate communication between LLMs (Large Language Models) and Ableton Live using OSC (Open Sound Control). It allows for the sending and receiving of messages to and from Ableton Live.

Use cases

Use cases for the Ableton Live MCP Server include automating music production tasks, controlling live performances, and integrating LLMs for creative music composition and arrangement.

How to use

To use the Ableton Live MCP Server, first install the necessary dependencies and clone the repository. Then, run the OSC daemon to handle communication between the MCP server and Ableton Live. You can send commands to Ableton Live through MCP clients by connecting to the server.

Key features

Key features include an MCP-compatible API for controlling Ableton Live, the use of python-osc for OSC message handling, and request-response handling for Ableton Live commands. It is based on the AbletonOSC implementation.

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

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

1. Install uv (https://docs.astral.sh/uv/getting-started/installation):

   curl -LsSf https://astral.sh/uv/install.sh | sh
   

2. Clone the repository:

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

3. Install the project and its dependencies:

   uv sync
   

4. 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:

This configuration ensures that:

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