- **JSON**: Machine-readable for programmatic use
### Batch Operations
Control multiple devices simultaneously:
- Set 50 shades at once
- Configure multiple thermostats
- Efficient API usage
### Smart Error Handling
- Clear, actionable error messages
- Guides users to solutions
- Handles authentication failures gracefully
- Session expiration detection
### Response Management
- 25,000 character limit with smart truncation
- Helpful pagination guidance
- Type-specific formatting for devices
- Grouped displays in Markdown
## 🚀 Quick Start
### 1. Install Dependencies
```bash
chmod +x setup.sh
./setup.sh
```
Or manually:
```bash
pip install -r requirements.txt
```
### 2. Get Crestron Auth Token
1. Open Crestron Home mobile app
2. Go to: **Installer Settings** → **System Control Options** → **Web API Settings**
3. Tap **Update Token**
4. Copy the token
### 3. Configure
Edit `env.example` and save as `.env`:
```bash
CRESTRON_HOST=192.168.1.100
CRESTRON_AUTH_TOKEN=your-token-here
```
### 4. Run Server
```bash
python crestron_mcp.py
```
### 5. Integrate with Claude Desktop
Add to your Claude Desktop config:
**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
```json
{
"mcpServers": {
"crestron": {
"command": "python",
"args": ["/absolute/path/to/crestron_mcp.py"]
}
}
}
```
## 📋 Example Workflows
### Italian User Command
**User**: "Spegni la luce del lampadario in soggiorno"
**Workflow**:
1. `crestron_authenticate` - Establish session
2. `crestron_list_rooms` - Find "soggiorno" room
3. `crestron_resolve_device` - Match "lampadario" to device ID
4. Control the device (using appropriate tool based on type)
### Climate Control
**User**: "Set bedroom to 72 degrees cool"
**Workflow**:
1. `crestron_authenticate`
2. `crestron_get_thermostats` - Find bedroom thermostat
3. `crestron_set_thermostat_setpoint` - Set cooling to 72°
4. `crestron_set_thermostat_mode` - Switch to COOL mode
### Batch Shade Control
**User**: "Close all living room shades"
**Workflow**:
1. `crestron_authenticate`
2. `crestron_list_devices` - Filter by room and type "shade"
3. `crestron_set_shade_position` - Batch operation to position 0
