Package (pypi 12.0.3)

uvx postfader-fl-studio-mcp

Or add to your MCP client config:

{
  "mcpServers": {
    "postfader-fl-studio-mcp": {
      "command": "uvx",
      "args": [
        "postfader-fl-studio-mcp"
      ],
      "env": {
        "FL_BRIDGE_ENABLE_MIDI": "<YOUR_VALUE>",
        "FL_BRIDGE_MIDI_PORT": "<YOUR_VALUE>",
        "FL_STUDIO_USER_DATA_DIR": "<YOUR_VALUE>"
      }
    }
  }
}

FL_BRIDGE_ENABLE_MIDI required — Set to 1 to build the MIDI SysEx transport. Without it the server cannot reach FL Studio.
FL_BRIDGE_MIDI_PORT required — Exact virtual MIDI endpoint name shared with FL Studio. PostFader does not install or configure a virtual MIDI provider.
FL_STUDIO_USER_DATA_DIR required — Absolute FL Studio user-data directory containing Settings/Hardware.
