Ableton Live MCP for Codex
The author built an MCP server so Codex can control Ableton Live, including running Python inside Live.
Codex built a full EDM track and a piano duet from scratch in minutes in Ableton, shown in two demo videos with the prompts listed.
Overview
How it was set up
Codex CLI with a custom Ableton Live MCP server, an Agent Audio Tap Max for Live device, and Ableton's Object model. Tested on Live Suite 12.3.8, macOS.
Worth knowing
Only tested on macOS with Live 12.3.8. The MCP edits the set directly and could corrupt it, so back up first.
A prompt to start from
In Ableton, make [song concept] using MIDI and Ableton devices for every instrument except [audio parts]. Then refine: [follow-up change, such as more dynamics or sidechain].
