OpenHue MCP Server

An MCP server that enables control of Philips Hue lights through Claude and other LLM interfaces using the OpenHue CLI.

Prerequisites

• Node.js (v16 or higher)
• Docker
• Claude for Desktop (optional, for testing)

Bridge Setup

Before using the server, you need to set up the OpenHue CLI with your Hue Bridge:

1. Run the setup command:

# On Linux/macOS:
docker run -v "${HOME}/.openhue:/.openhue" --rm --name=openhue -it openhue/cli setup

# On Windows (PowerShell):
docker run -v "${env:USERPROFILE}\.openhue:/.openhue" --rm --name=openhue -it openhue/cli setup

2. Follow the on-screen instructions:

3. Verify the setup by listing your lights:

# On Linux/macOS:
docker run -v "${HOME}/.openhue:/.openhue" --rm --name=openhue -it openhue/cli get lights

# On Windows (PowerShell):
docker run -v "${env:USERPROFILE}\.openhue:/.openhue" --rm --name=openhue -it openhue/cli get lights

If you see your lights listed, the setup is complete and you're ready to use the MCP server.

Installation

1. Clone the repository:

git clone 
cd claude-mcp-openhue

2. Install dependencies:

npm install

3. Build the project:

Usage with Claude Desktop

1. Open your Claude Desktop configuration file:

2. Add the server configuration:

{
  "mcpServers": {
    "hue": {
      "command": "node",
      "args": ["/absolute/path/to/build/index.js"]
    }
  }
}

3. Restart Claude Desktop

4. Look for the hammer icon to verify the server is connected

Example Commands

Once connected, you can ask Claude natural language questions like:

• "What lights do I have in the living room?"
• "Turn on all the lights in the kitchen"
• "Set the bedroom lights to 50% brightness"
• "Change the office lights to blue"
• "Activate the 'Relaxing' scene"
• "What scenes are available in the den?"
