🚀 Quick Start

Prerequisites

• Node.js 18+
• Philips Hue Bridge (v2) on your local network
• Claude Desktop or compatible MCP client

1. Installation

git clone https://github.com/your-username/hue-mcp.git
cd hue-mcp
npm install

2. Setup Your Hue Bridge

Option A: Web Setup (Recommended)

npm run setup:web

This launches a beautiful setup wizard at http://localhost:3000 that will:

• Auto-discover your Hue bridge
• Guide you through authentication
• Test your connection
• Generate Claude Desktop configuration

Option B: CLI Setup

npm run setup

3. Add to Claude Desktop

Copy the generated configuration to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "hue-lights": {
      "command": "node",
      "args": ["/path/to/hue-mcp/dist/index.js"],
      "env": {
        "HUE_BRIDGE_IP": "192.168.1.100",
        "HUE_API_KEY": "your-api-key-here"
      }
    }
  }
}

4. Start Using

Restart Claude Desktop and try these commands:

• "Turn on the living room lights"
• "Set bedroom to warm white at 30%"
• "Activate the energize scene"
• "Show me all available lights"
• "Turn everything off"

💡 Optimal Usage Patterns

For Chatbot Efficiency

🔍 Discovery Queries

❌ Avoid: "List all lights" (potentially large response)
✅ Better: "Find lights that are on" (filtered, relevant)
✅ Best: "Quick status" (minimal context summary)

🏠 Room Controls

❌ Avoid: Multiple individual light commands
✅ Better: "Turn off all bedroom lights" (single room command)
✅ Best: "Set bedroom to relaxing mood" (scene activation)

📊 Status Checking

❌ Avoid: Detailed system overview every time
✅ Better: "Minimal status" (compact summary)
✅ Best: Context-aware - detailed first time, minimal after

Response Size Guidelines

• First interaction: Use standard detail level for orientation
• Ongoing conversation: Use compact to preserve context window
• Troubleshooting: Use verbose for comprehensive information
• Quick checks: Use minimal for status updates

🎨 Natural Language Examples

🔍 Smart Search Queries

• "Find all kitchen lights" → Searches by room name
• "Show me lights that are on" → Filters by current state
• "Color bulbs in the bedroom" → Searches by capability and room
• "All unreachable lights" → Finds connectivity issues

💬 Conversation Efficiency Examples

• "Quick status" → Uses minimal context for fast response
• "What lights do I have?" (first time) → Standard detail level
• "What lights do I have?" (repeated) → Compact response
• "Turn on bedroom lights" → Suggests room control over individual lights

🎨 Colors & Moods

• "stormy dusk" → Deep blue-purple with low brightness
• "warm white" → Comfortable warm temperature
• "sunrise" → Orange-yellow with medium brightness
• "ocean" → Blue-cyan colors
• "fire" → Red-orange with high saturation

🌟 Atmospheric Scenes (Auto-Variation)

These keywords trigger realistic individual light variations:

• "thunderstorm", "stormy" → Varied blues with different intensities
• "sunset", "sunrise" → Gradient of warm colors across lights
• "fireplace", "candlelight" → Flickering warm variations
• "forest", "ocean" → Natural color variations
• "cozy", "romantic" → Subtle warm variations

Brightness & Settings

• "dim blue slowly" → Blue color with slow transition

• 5x longer cache lifetime (1min → 5min) with smart invalidation
• Bulk operations preferred over individual light controls
• Rate limiting protection with 2-minute discovery caching
• Parallel execution for atmospheric variations (all lights updated simultaneously)

Chatbot Context Management

• 75% smaller responses in compact mode
• Smart pagination - max 5-20 results based on detail level
• Progressive disclosure - minimal → standard → verbose
• Conversation state tracking - learns and adapts over time
• Query optimization - suggests more efficient alternatives

Memory & Context Window

• Adaptive response sizing based on conversation stage
• Context-aware parameters automatically optimized
• Intelligent truncation with clear continuation hints
• Tool selection guidance for optimal efficiency

🔍 Troubleshooting

Common Issues

"No bridges found"

• Ensure your Hue bridge is powered on and connected to the same network
• Try manual IP entry in the setup wizard

"Authentication failed"

• Make sure to press the physical button on your Hue bridge
• The button must be pressed within 30 seconds of starting authentication

"Connection test failed"

• Verify your bridge IP address is correct
• Check that your API key is valid
• Ensure your firewall allows connections to the bridge
