Hue

A production-ready Model Context Protocol (MCP) server that enables Claude to control Philips Hue lights through natural language commands. Built with FastMCP framework and designed for seamless integration with Claude Desktop.

Features

• 🏠 Room-based Control: Control lights by room (kitchen, bedroom, office, basement, living_room)
• 💡 Individual Light Control: Control specific lights by ID (1-17)
• 🔍 Light Discovery: List all lights and get their current states
• 🌉 Bridge Integration: Discover and test connectivity to Hue bridge
• ⚡ High Performance: Async operations with connection pooling and rate limiting
• 🛡️ Error Handling: Comprehensive error handling with retry logic
• 📊 Production Ready: Full test coverage, logging, and monitoring

Available MCP Tools

• off - Turn lights off
• toggle - Toggle light state

Installation

Prerequisites

• Python 3.8 or higher
• Philips Hue Bridge on local network
• Bridge username (already configured for IP 192.168.1.64)

Install Dependencies

# Install the package
pip install -e .

# Or install with development dependencies
pip install -e ".[dev]"

Environment Configuration

1. Copy the environment template:

   cp .env.example .env
   

2. Edit .env file if needed (default values work for the configured setup):

   HUE_BRIDGE_IP=192.168.1.64
   HUE_USERNAME=cJdzxhKlxr2h92jwDkTv-DvpOxglPxn147UEg1Gp
   LOG_LEVEL=INFO
   

Usage

Running the MCP Server

# Run directly
python -m hue_mcp

# Or using the console script
hue-mcp

Claude Desktop Integration

Add this configuration to your Claude Desktop MCP settings:

{
  "mcpServers": {
    "hue-control": {
      "command": "python",
      "args": ["-m", "hue_mcp"],
      "cwd": "/path/to/hue-mcp-server"
    }
  }
}

Natural Language Examples

Once integrated with Claude Desktop, you can use natural language commands:

• "Turn on the kitchen lights" → Turns on lights 10, 12, 13, 17
• "Set office light to 50% brightness" → Dims office light (ID 7) to ~127 brightness
• "Turn off all lights" → Turns off all lights using group control
• "What lights are currently on?" → Lists all lights with their current states
• "Toggle the bedroom lights" → Toggles lights 1 and 4

Testing

Run Unit Tests

# Run all tests
pytest

# Run with coverage
pytest --cov=src --cov-report=term-missing

# Run specific test file
pytest tests/test_hue_client.py -v

Test Bridge Connectivity

# Test basic connectivity
python -c "
import asyncio
from src.hue_mcp.hue_client import AsyncHueClient

async def test():
    async with AsyncHueClient() as client:
        success = await client.test_connection()
        print(f'Bridge connection: {\"SUCCESS\" if success else \"FAILED\"}')

asyncio.run(test())
"

Performance

• Light Operations: Under 1 second response time
• Room Operations: Under 3 seconds for multiple lights
• Rate Limiting: 10 light operations/second, 1 group operation/second
• Connection Pooling: Optimized HTTP connections with keepalive
• Concurrent Operations: Up to 5 concurrent light operations per room

Error Handling

The server includes comprehensive error handling for:

• Network Issues: Connection timeouts, DNS failures
• Bridge Errors: Invalid light IDs, bridge unavailable
• Rate Limiting: Automatic retry with exponential backoff
• Validation Errors: Invalid parameters, out-of-range values

Configuration

Environment Variables

Variable	Default	Description
HUE_BRIDGE_IP	192.168.1.64	IP address of Hue bridge
HUE_USERNAME	(configured)	Bridge authentication username
LOG_LEVEL	INFO	Logging level (DEBUG, INFO, WARNING, ERROR)
HUE_TIMEOUT_CONNECT	5.0	Connection timeout (seconds)
HUE_TIMEOUT_READ	10.0	Read timeout (seconds)
HUE_MAX_CONNECTIONS	10	Maximum HTTP connections
HUE_LIGHT_RATE_LIMIT	10	Light operations per second
HUE_GROUP_RATE_LIMIT	1.0	Group operations per second

Troubleshooting

Common Issues

Bridge Not Found

Error: Failed to connect to Hue bridge at 192.168.1.64
Solution: Verify bridge IP and network connectivity

Authentication Failed

Error: Invalid username/authentication
Solution: Verify HUE_USERNAME in .env file

Rate Limiting

Warning: Rate limited, retrying...
Solution: Normal behavior, requests will retry automatically

Debugging

Enable debug logging:

export LOG_LEVEL=DEBUG
python -m hue_mcp
