- Chord library with 25+ chord qualities
- Flexible durations: numeric beats, standard strings, dotted, triplet
- Seven built-in music theory reference documents as MCP resources
- Three transport modes: stdio, HTTP, Cloudflare Workers
- Interactive piano-roll preview and audio playback in supported MCP clients
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below

- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Deploy remotely via Cloudflare Workers (https://midi-mcp-server.tubone24.workers.dev/mcp) or run locally as a stdio or HTTP server. Use the create_midi tool to generate a MIDI file from a composition object, and parse_chord to resolve chord names into pitches. See the README for configuration examples for each transport.

Deployment Options
Option A — Remote (Cloudflare Workers)
A pre-deployed remote server is available:
https://midi-mcp-server.tubone24.workers.dev/mcp
Add it to any MCP client that supports Streamable HTTP (e.g., Claude.ai):
{
"mcpServers": {
"midi": {
"type": "http",
"url": "https://midi-mcp-server.tubone24.workers.dev/mcp"
}
}
}
Option B — Local stdio (recommended for desktop clients)
Build and configure as a local stdio server:
npm install
npm run build
{
"mcpServers": {
"musicComposer": {
"command": "node",
"args": ["/path/to/midi-mcp-server/build/index.js"]
}
}
}
Option C — Local HTTP
Run as a local Streamable HTTP server:
```bash
node build/index.js --http
