A Model Context Protocol (MCP) integration for controlling Home Assistant devices using AI assistants.
If you already use Home Assistant MCP, the home assistant mcp mcp server is the piece that lets your assistant work with it directly. A Model Context Protocol (MCP) integration for controlling Home Assistant devices using AI assistants.
This MCP allows AI assistants to control your Home Assistant devices. It provides tools to:
The server ships on npm as @smithery/cli, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Configuration is passed through the environment: HOME_ASSISTANT_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by hpohlmann; worth a glance at recent repository activity before you build anything load-bearing on it.
