Ableton Live + Roo Code: Complete MCP Integration

Ableton Live is a MCP server that an MCP server to control Ableton Live..

When integrated with Roo Code, you can:

• Create, modify, and control audio/MIDI tracks
• Control live performance parameters and session view
• Send and receive OSC messages for real-time control

This guide provides step-by-step instructions to set up Ableton Live in Roo Code, including configuration, examples, and troubleshooting.

What You'll Achieve

After completing this setup:

• Ableton Live will be fully integrated and operational
• You can use Ableton Live tools directly in Roo Code
• All Ableton Live capabilities will be available for your workflows
• Access to 4 different tools

Prerequisites

Before starting, ensure you have:

• Python 3.8+
• Git
• Ableton Live installed
• Roo Code installed and configured
• Compatible operating system (Windows, macOS, Linux)

Installation

Step 1: Install Ableton Live

Manual installation steps:

1. Install Python 3.8 or higher
2. Install uv package manager
3. Clone repository: git clone https://github.com/Simon-Kansara/ableton-live-mcp-server.git
4. Navigate to project: cd mcp_ableton_server
5. Install dependencies: uv sync

Configuration

Step 2: Configure Roo Code

1. Locate your configuration file:

   • Windows: %USERPROFILE%\.roo\mcp_settings.json
   • macOS: ~/.roo/mcp_settings.json
   • Linux: ~/.roo/mcp_settings.json

2. Add server configuration:

{
  "mcpServers": {
    "ableton-live": {
      "command": "npx",
      "args": ["-y", "ableton-live"],
      "env": {
        
      }
    }
  }
}

3. Restart Roo Code

Completely quit and restart Roo Code to load the new configuration.

Examples

Once configured, you can use Ableton Live in Roo Code:

Prepare Recording Setup

Set up tracks for recording a rock band

Ask Roo Code: "Prepare a set to record a rock band with drums, bass, guitar, and vocals"

Expected Result: Multiple audio tracks created with appropriate input routing and naming

Configure Voice Track Routing

Set input routing for vocal tracks

Ask Roo Code: "Set the input routing channel of all tracks that have "voice" in their name to Ext. In 2"

Expected Result: All vocal tracks configured to receive input from external input 2

Live Performance Setup

Configure session view for live performance

Ask Roo Code: "Set up a live performance session with 8 tracks and 16 scenes for electronic music"

Expected Result: Session view configured with tracks and scenes ready for live triggering

Transport Control

Control playback and recording

Ask Roo Code: "Start recording on track 3 and set tempo to 120 BPM"

Expected Result: Recording initiated on specified track with tempo adjusted

Testing Your Setup

1. Start a new conversation in Roo Code
2. Ask Roo Code to list available tools
3. Try using Ableton Live functionality

Test prompts:

• "Type @ and verify Ableton Live appears in the tools list"
• "Ask: "Use Ableton Live to help with my task""
• "Check Roo Code output panel for server connection status"

Troubleshooting

Common Issues

Ableton Live Not Responding

Symptoms: OSC messages not received, No communication with Live

Cause: OSC control surface not enabled or incorrect port configuration

Solution:

• Enable AbletonOSC control surface in Live preferences
• Verify OSC ports match configuration (11000/11001)
• Restart Ableton Live after configuration changes
• Check firewall settings allow OSC communication

Port Already in Use

Symptoms: Socket binding errors, Port conflict messages

Cause: Another application using configured ports

Solution:

• Check which process is using the port: netstat -tulpn | grep :65432
• Kill conflicting process or change port in osc_daemon.py
• Use alternative ports (e.g., 65433, 11002, 11003)
• Restart both server and Ableton Live

Python Dependencies Missing

Symptoms: Import errors, Module not found errors

Cause: Required packages not installed properly

Solution:

• Run uv sync to install all dependencies
• Verify Python 3.8+ is installed: python --version
• Check virtual environment is activated
• Install missing packages manually: pip install python-osc fastmcp

OSC Messages Not Routing

Symptoms: Commands not affecting Live, No response from controls

Cause: Incorrect OSC routing or message format

Solution:

• Verify OSC address patterns match Live expectations
• Check OSC message format and data types
• Test basic OSC connectivity with simple messages
• Review osc_daemon.py configuration for routing rules

MCP Server Not Connecting

Symptoms: Server not appearing in tools list, Connection timeout, MCP tools unavailable

Cause: Incorrect configuration or server not starting

Solution:

• Verify mcp_settings.json syntax is correct
• Check that Node.js and npx are installed and in PATH
• View Roo Code output panel for error messages
• Test server command manually in terminal: npx -y {server_id}
• Ensure environment variables are properly set

Permission Denied Errors

Symptoms: Cannot execute commands, File access denied, Terminal commands blocked

Cause: Roo Code requires explicit permission for file and command operations

Solution:

• Review and approve permission requests when prompted
• Check VS Code workspace trust settings
• Enable necessary permissions in Roo Code settings
• Verify file and folder permissions on your system

API Key or Model Issues

Symptoms: Authentication failed, Model not responding, No AI completions

Cause: AI model API key not configured or invalid

Solution:

• Verify API key is correctly set in Roo Code settings
• Check API key has sufficient credits/quota
• Test with a different AI model provider
• Review Roo Code output panel for API error details

Custom Mode Not Working with MCP

Symptoms: MCP tools not available in custom mode, Mode cannot access server

Cause: Custom mode configuration does not include MCP tool permissions

Solution:

• Edit custom mode configuration to include MCP tools
• Add "Use MCP" to available tools in mode definition
• Ensure mode has appropriate permissions for external tools
• Test with default mode first to verify MCP server works

Extension Conflicts

Symptoms: Roo Code not responding, VS Code performance issues, Unexpected behavior

Cause: Conflicts with other AI coding extensions

Solution:

• Disable other AI coding extensions (Cline, Continue, etc.)
• Restart VS Code after disabling conflicting extensions
• Check VS Code extension logs for conflict errors
• Use only one AI coding assistant extension at a time

Ableton Live not appearing in Roo Code

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check Ableton Live installation
• Restart Roo Code
• Check logs for error messages
