- Add rests and ties

### 📝 Notation
- Set key signatures (all major and minor keys)
- Set time signatures
- Add dynamics (pp, p, mp, mf, f, ff, etc.)
- Add tempo markings
- Add slurs and articulations

### 🎵 Harmony Tools (화성학)
- Analyze chord quality and Roman numerals
- Suggest next chords based on context
- Generate chord progressions
- Check voice leading rules (parallel 5ths/8ves)

### 🎻 Orchestration Tools (오케스트레이션)
- Complete instrument database with ranges
- Check playability (instrument range validation)
- Transposition for transposing instruments
- Get detailed instrument information

### 🔍 Query Tools

- Species counterpoint exercises

## Installation

### Prerequisites
- Python 3.11+
- Steinberg Dorico (with Remote Control enabled)
- Claude Desktop or ChatGPT Desktop

### Install from PyPI (Recommended)

```bash
pip install dorico-mcp-server
```

### Install from Source (Development)

```bash
git clone https://github.com/happycastle114/dorico-mcp-server.git
cd dorico-mcp-server
pip install -e ".[dev]"
```

### Enable Dorico Remote Control

1. Open Dorico
2. Go to **Preferences** → **General**
3. Enable **Allow remote control**
4. Note the port number (usually 4560)

## Configuration

### Claude Desktop

Add to your Claude Desktop configuration:

**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
**Linux**: `~/.config/Claude/claude_desktop_config.json`

```json
{
  "mcpServers": {
    "dorico": {
      "command": "python",
      "args": ["-m", "dorico_mcp.server", "--stdio"]
    }
  }
}
```

### ChatGPT Desktop

Add to your ChatGPT Desktop configuration:

**macOS**: `~/Library/Application Support/com.openai.chat/mcp.json`
**Windows**: `%LOCALAPPDATA%\com.openai.chat\mcp.json`
**Linux**: `~/.config/com.openai.chat/mcp.json`

```json
{
  "mcpServers": {
    "dorico": {
      "command": "python",
      "args": ["-m", "dorico_mcp.server", "--stdio"]
    }
  }
}
```

> **Note**: Restart the app after updating the configuration.

## Usage Examples

### Creating a Score

```
"Create a new score for string quartet in G major, 3/4 time, tempo 120"
```

### Adding Notes

```
"Add a C major chord (C4, E4, G4) as quarter notes"
"Add a melody: C4, D4, E4, F4, G4 as eighth notes"
```

### Harmony Analysis

```
"What chord would work well after I-IV-V?"
"Generate a 8-bar chord progression in A minor with an authentic cadence"
```

### Orchestration Help

```
"Is F2 playable on the violin?"
"What's the comfortable range for French horn?"
"What transposition does the Bb clarinet use?"
```

### Counterpoint

```
"Check if this counterpoint follows first species rules: 
  Cantus: C4, D4, E4, F4, E4, D4, C4
  Counterpoint: G4, A4, B4, C5, B4, A4, G4"
"Generate a counterpoint melody above this cantus firmus: D4, E4, F4, G4, F4, E4, D4"
```

### Voice Leading Validation

```
"Check this four-part harmony for parallel fifths:
  Soprano: C5, D5, E5
  Alto: E4, F4, G4
  Tenor: G3, A3, B3
  Bass: C3, D3, E3"
```

## Dorico Remote Control API

This server communicates with Dorico via its WebSocket-based Remote Control API:

- **Protocol**: WebSocket (JSON messages)
- **Port**: Dynamic (usually 4560-4565)
- **Authentication**: Session token (stored locally after first approval)

### Key Limitations

- **Read access is limited**: Can only read currently selected items
- **Write-focused**: Best for sending commands/input
- **Full score reading**: Requires MusicXML export
