Prerequisites

1. Go 1.21 or later
2. Philips Hue Bridge with v2 API support
3. Hue Bridge API username (see setup below)

Setup

1. Find Your Hue Bridge

Use the built-in discovery command:

# Automatically discover bridges on your network
./hue discover

# Example output:
# 🌉 Bridge 1
#    ID: 001788fffe696373
#    IP Address: 192.168.87.51
#    Status: ✅ Reachable
#    Name: Hue Bridge

Alternatively, find your bridge IP manually:

curl https://discovery.meethue.com/

2. Get Your API Username

Press the link button on your Hue Bridge, then run:

# Use the IP from discovery above
curl -X POST http://<BRIDGE_IP>/api -H "Content-Type: application/json" -d '{"devicetype":"hue#cli"}'

3. Build the MCP Server

# Clone the repository
git clone https://github.com/kungfusheep/hue.git
cd hue

# Build the binary
go build -o hue

4. Set Environment Variables

export HUE_BRIDGE_IP="192.168.1.100"  # Your bridge IP
export HUE_USERNAME="your-api-username-here"

5. Configure Claude Desktop (example)

Add to your Claude Desktop configuration file:

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

{
  "mcpServers": {
    "hue": {
      "command": "/absolute/path/to/hue",
      "env": {
        "HUE_BRIDGE_IP": "YOUR_BRIDGE_IP",
        "HUE_USERNAME": "YOUR_API_USERNAME"
      }
    }
  }
}

6. Restart Claude Desktop

Quit and restart Claude Desktop to load the new configuration.

CLI Usage

The hue binary functions as both an MCP server and a standalone CLI tool:

# Run as MCP server (for Claude Desktop)
hue

# Run CLI commands directly
hue <command>

# Bridge discovery
hue discover          # Find bridges automatically
hue discover --json   # JSON output for scripting

# Examples:
hue lights list
hue lights on "Office Lamp"
hue lights color "Office Lamp" blue
hue lights brightness "Office Lamp" 50

# Group control
hue groups list
hue groups on "Living Room"
hue groups color "Kitchen" warm
hue groups rooms  # List all rooms

# Effects
hue effects flash "Office Lamp" --color red --count 3
hue effects pulse "Bedroom Light" --min 10 --max 90
hue effects stop <sequence-id>

# Native Hue scenes
hue hue-scenes list
hue hue-scenes activate "Relax"

# Cached scenes (from MCP)
hue scenes list
hue scenes recall "alien_artifact_discovery"

# Sensors
hue sensors motion     # List motion sensors
hue sensors temperature # List temperature sensors
hue sensors light      # List light level sensors

# Real-time event streaming
hue stream             # Stream all events
hue stream -f motion   # Stream only motion events
hue stream -f "motion,temperature"  # Multiple event types
hue stream -r          # Show raw JSON events

# Batch commands
hue batch -f commands.json

The CLI supports friendly names for all lights and rooms - no need to use UUIDs!

Key Features Explained

🚀 Non-blocking Operations

All lighting commands execute asynchronously by default. This means:

• Claude responds immediately while lights change in the background
• You can stack multiple effects on different lights
• Complex sequences won't freeze the conversation
• Use async: false in batch commands if you need to wait

🎭 Effects System

The MCP includes a powerful effects engine:

• Pre-built effects for common scenarios (alerts, ambiance, parties)
• Custom sequences for precise choreography
• Parallel execution - run multiple effects simultaneously
• Loop support - effects can repeat indefinitely
• See EFFECTS_GUIDE.md for detailed examples

💾 Scene Caching for RPGs

Perfect for game masters who need instant atmosphere changes:

First time - Create and cache:

"Set up mysterious alien artifact discovery lighting"
→ Claude creates complex 15-command sequence with purple/blue colors, pulsing, flickering
→ Automatically caches as "alien_artifact_discovery"

Later in the game - Instant recall:

"Recall the alien artifact scene"
→ Instantly recreates the exact same atmosphere

Features:

• Cache complex multi-command scenes with cache_name in batch_commands
• Instant recall with recall_scene
• Track usage with list_cached_scenes
• Export scenes for sharing with other GMs
• Scenes persist throughout your Claude session

🔄 Real-time Events

Subscribe to live updates from your Hue system:

• Motion sensor triggers
• Button presses
• Light state changes
• Temperature updates

Troubleshooting

1. "Failed to connect to Hue bridge"

   • Verify your bridge IP is correct
   • Ensure your API username is valid
   • Check you're on the same network as the bridge

2. "Light/group not found"

   • Use list_lights or list_groups to see available IDs
   • Light names are case-sensitive

3. Effects not working

   • Not all lights support all effects
   • Use dynamic effect discovery to see supported effects

Development

Run tests:

go test ./...

Run comprehensive test suite:

# Set environment variables first
go run test_comprehensive.go
