Ccu MCP

Talk to your HomeMatic smart home from Claude, Cursor, or any MCP client. ccu-mcp connects to the CCU's built-in JSON-RPC API and exposes your devices, rooms, programs, and system variables as MCP tools. No addons, no XML-API, no cloud - just a direct connection to the CCU on your local network.

People connecting automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

Set CCU_HOST, CCU_PASSWORD, CCU_HTTPS, CCU_PORT, CCU_PROD_HOST, CCU_PROD_USER, CCU_PROD_PASSWORD, CCU_PROD_HTTPS, CCU_PROD_PROTECTED, CCU_DEV_HOST before connecting. CCU_PROFILES, CCU_DEFAULT_PROFILE are optional or environment-specific per the README.

Claude Code

claude mcp add claymore666-ccu-mcp -- npx -y ccu-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "claymore666-ccu-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "ccu-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
