# MIDI MCP Server
## Overview
MIDI MCP Server is a Model Context Protocol (MCP) server that enables AI models to generate MIDI files from text-based music data. This tool allows for programmatic creation of musical compositions through a standardized interface.
## Installation
```bash
npm install
npm run build
```
## Usage with MCP Clients (e.g., Cline)
After building the project, simply add the server to your MCP client configuration:
```json
"mcpServers": {
"musicComposer": {
"command": "node",
"args": ["/path/to/midi-mcp-server/build/index.js"]
}
}
```
Replace `/path/to/` with the actual path to your project directory.
## Features
- Generate MIDI files from structured JSON music data
- Support for multiple tracks and instruments
- Customizable tempo, time signature, and note properties
- Save MIDI files to specified locations
## Tool: create_midi
The server provides a tool called `create_midi` that generates MIDI files from structured music data.
### Input Parameters
- `title`: String - The title of the composition
- `composition`: String - A JSON string representing the music data
- `output_path`: String - Path where the MIDI file will be saved
### Composition Format
The composition should follow this structure:
```json
{
"bpm": number,
"timeSignature": { "numerator": number, "denominator": number },
"tracks": [
{
"name": string,
"instrument": number,
"notes": [
{ "pitch": number, "startTime": number, "duration": number, "velocity": number }
]
}
]
}
```
#### Properties
- `bpm`: Tempo in beats per minute
- `timeSignature`: Time signature (e.g., `{numerator: 4, denominator: 4}` for 4/4 time)
- `tracks`: Array of instrument tracks
- `name`: Track name
- `instrument`: MIDI program number (0-127)
- `notes`: Array of note objects
- `pitch`: MIDI note number (0-127)
- `startTime`: Start time in beats
- `duration`: Note duration in beats
- `velocity`: Note velocity/volume (0-127)
## Example
```javascript
const composition = {
"bpm": 120,
"timeSignature": { "numerator": 4, "denominator": 4 },
"tracks": [
{
"name": "Piano",
"instrument": 0,
"notes": [
{ "pitch": 60, "startTime": 0, "duration": 1, "velocity": 100 },
{ "pitch": 64, "startTime": 1, "duration": 1, "velocity": 100 },
{ "pitch": 67, "startTime": 2, "duration": 1, "velocity": 100 }
]
}
]
};
```
## Dependencies
- @modelcontextprotocol/sdk: MCP server implementation
- midi-writer-js: Library for creating MIDI files
## Demo
For example, the prompt below, which is a request to create a minor scale 8-bar choral piece, can be processed by the server:
```text
8小節の合唱曲を作って。
若干マイナー調で、メロディックな音階を作ってほしい
```

## Note on Local Execution
This MCP server runs locally and communicates via standard input/output (stdio). No network configuration is required as the MCP client will automatically start the server process and establish communication.
