Installation

M4L Bridge

Download

Purchase and download live-mcp-bridge.zip from the Gumroad product page.

Install

1. Unzip the archive — you’ll get a live-mcp-bridge/ folder containing the .amxd device and supporting scripts
2. Place the folder somewhere permanent (e.g. your Max for Live devices folder)
3. In Ableton Live, drag Live MCP Bridge.amxd onto any MIDI track
4. The device starts automatically — check the Max console for confirmation

Verify

Open the Max console (Max menu > Window > Max Console). You should see:

lom-handler-v8.js: script loaded
Live MCP Bridge listening on port 19740

Configuration

The server connects to the bridge on 127.0.0.1:19740 by default. Override with environment variables:

• LIVE_MCP_BRIDGE_HOST — Bridge hostname (default: 127.0.0.1)
• LIVE_MCP_BRIDGE_PORT — Bridge port (default: 19740)
