# The Unofficial and Awesome Home Assistant MCP Server
<!-- mcp-name: io.github.homeassistant-ai/ha-mcp -->
A comprehensive Model Context Protocol (MCP) server that enables AI assistants to interact with Home Assistant. Using natural language, control smart home devices, query states, execute services and manage your automations.
🚀 Get Started
The recommended way to run ha-mcp is the HA-MCP Custom Component. It installs into Home Assistant through HACS, runs the full server in-process, and works on every Home Assistant installation type — Home Assistant OS, Supervised, Container, and Core — with full feature parity. It is the easiest setup in every case, with no access token to manage.
Add it to Home Assistant via HACS (the preferred install):
Quick start:
- Install the HA-MCP Custom Component from HACS — click the badge above, or in HACS open Integrations → ⋮ → Custom repositories, add https://github.com/homeassistant-ai/ha-mcp-integration (category: Integration), then Download.
- Restart Home Assistant.
- Go to Settings → Devices & Services → Add Integration, search for HA-MCP Custom Component, choose HA-MCP Server, and click Submit. Creating the entry starts the server.
- Copy the connect URL from the entry's Configure screen (Settings → Devices & Services → HA-MCP Custom Component → HA-MCP Server → Configure) — it is also printed in the Home Assistant log. A notification confirms the server started and points you there.
- Paste that URL into your AI client — done.
