概要

What is Model Context Protocol Server for Home Assistant?

It is an MCP server that bridges a local Home Assistant instance with Language Learning Models (LLMs), enabling natural language control and monitoring of smart home devices. It provides a comprehensive API for device control, automation management, add-on management, and package management (HACS).

How to use Model Context Protocol Server for Home Assistant?

Install via Node.js (npm install, npm run build) or Docker Compose. Configure environment variables: HASS_HOST, HASS_TOKEN, HASS_SOCKET_URL, and server options. Run the server and connect an MCP client (e.g., Claude Desktop) by adding the server to the client config with the command node <path>/dist and environment variables.
