Documentation Overview
Mixx-DJ-MCP
AI-native DJ control for Mixxx. 80+ operations across decks, library, effects, mixer, stems, transitions, video, and more. Talk to your DJ software like a colleague.
Say: "Load Daft Punk on deck 2, sync it, cue the drop, then fade in on the next beat."
It happens.

One command to start
Configure Mixxx OSC once (one minute): Preferences > MIDI/OSC > Enable OSC, set out 11118, in 11119, send to 127.0.0.1, restart. Done.
Your AI assistant (Claude, Cursor, opencode) can now control your decks.
