Mixx DJ
FastMCP server for Mixxx DJ software control via OSC protocol
Runs on your machine from its package; the steps are below.
What it does
- Reads
- Writes
- High impact
At most: moves money, runs code or commands, deletes data, or sends messages for you.
What it costs
FreeOdel charges nothing per call. The publisher may charge for its own service.
Runs locally over stdio
This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).
Distributed as an MCP bundle (`https://github.com/sandraschi/mixx-dj-mcp/releases/download/v0.2.0/mixx-dj-mcp-v0.2.0.mcpb`) — download it and import the bundle in your MCP client.
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
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.

Fleet integrations
Mixx-DJ-MCP is a Fleet Audio Hub -- it connects to other MCP servers for a unified DJ ecosystem:
| Server | Integration |
|---|---|
plex-mcp | Cross-reference vinyl with digital library |
songgeneration-mcp | AI music generation loaded direct to decks |
sfx-mcp | Sound effects triggered during live sets |
vfx-mcp | Real-time video effects on video output |
stems-mcp | External stem separation engine |
davinci-resolve-mcp | Export stems to Fairlight for post-production |
reaper-mcp | Export stems to Reaper DAW |
inkscape-mcp | AI skin colour palette generation |
Fleet Crossconnects (Companions)
mixx-dj-mcp works completely standalone. You can optionally connect it with companion servers in the sandraschi fleet to unlock extended features:
| Companion Server | Feature Unlocked | Status | Setup |
|---|---|---|---|
resolume-mcp | ndi-vj-routing, osc-clip-sync, live-projection-mapping | Optional | Install Guide |
resonite-mcp | virtual-world-stage, nekomimi-avatar-dance, osc-bpm-telemetry | Optional | Install Guide |
Self-Contained Companions: Fleet companions operate independently. Installing companions does not trigger transitive dependency chains.
