🚀 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:

1. 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.
2. Restart Home Assistant.
3. 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.
4. 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.
5. Paste that URL into your AI client — done.

Connect URL. The Configure screen gives you a Home Assistant webhook URL for remote clients — https://<your-ha-domain>/api/webhook/<webhook-id> through Nabu Casa or any reverse proxy already pointed at Home Assistant (locally, http://<ha-host>:8123/api/webhook/<webhook-id>). For clients on the same network,
