FastMCP server for Mixxx DJ software control using the OSC protocol. The project is described as offering 80+ operations spanning decks, library, effects, mixer, stems, transitions, and video. It is positioned for Model Context Protocol integration and is associated with AI-native DJ control.

🛠️ Key Features

FastMCP-based server
Mixxx control via OSC protocol
80+ operations across multiple Mixxx areas (decks, library, effects, mixer, stems, transitions, video)

🚀 Use Cases

Programmatic DJ control for Mixxx (multi-area automation)
Triggering deck, effects, mixer, stems, transitions, and video actions from external systems

⚡ Developer Benefits

Model Context Protocol-compatible server implementation
OSC-based interface for controlling Mixxx software
Uses Python 3.12 (per repository badges)

⚠️ Limitations

Limited scope to Mixxx DJ software control (via OSC)
Server capabilities are bounded to the documented operation areas (decks, library, effects, mixer, stems, transitions, video)

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

bash

uv sync && uv run uvicorn mixx_dj_mcp.server:app --port 11116

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.

What it does

You say	The AI does
"Play deck 2"	`mixx_deck(operation="play_pause", deck=2)` — OSC to Mixxx
"Find some 128 BPM tech house"	`mixx_library(operation="search", query="tech house")`
"Add reverb to the outgoing track"	`mixx_effects(operation="chain_load", rack=1, effect="Reverb")`
"Plan a 30-min drum & bass set"	`mixx_ai_set(operation="plan", style="drum and bass")`
"Record this set"	`mixx_recording(operation="start")`
"Analyse this track's key"	`mixx_analyze(operation="track", path="C:/Music/track.mp3")`
"Show me my most-played tracks"	`mixx_history(operation="profile")`
"Transition with an echo out"	`mixx_transition(operation="apply", effect="echo_out")`
