What is Home Assistant MCP Server?

Home Assistant MCP Server is a Model Context Protocol (MCP) server for integrating with Home Assistant, enabling LLMs to control and query your smart home via natural language. It works with any MCP‑compatible client, such as Claude Desktop.

How to use Home Assistant MCP Server?

Install globally with bun install -g home-assistant-mcp-server or build from source. Configure a .env file with HASS_URL and HASS_TOKEN (or HASS_MOCK=true for demo). Run as a standalone server with home-assistant-mcp-server (default HTTP/SSE) or add the --stdio flag for stdio transport. For Claude Desktop, edit claude_desktop_config.json to include the server command and environment variables.
