MIDI Control MCP

Example Use Cases

• 1

  Discover available MIDI output ports on the host system to route generated messages to appropriate devices.

• 2

  Send scheduled or immediate note events (with velocity, duration, and release) to hardware or virtual MIDI outputs for automated performance or testing.

• 3

  Programmatically send control change messages to adjust synth parameters, mixers, or external devices as part of a composition or live automation workflow.

Description

This repository implements a Model Context Protocol (MCP) server to interact with MIDI output devices. It provides tools to list available MIDI output ports and to send batches of note and control-change messages (with timing, velocity, duration, and channel options). It is written in TypeScript, supports development workflows (build/watch), and includes instructions for integrating with Claude Desktop and testing with virtual MIDI ports such as loopMIDI. The server is suited for automating MIDI control and routing in local setups or agent-driven workflows.
