Mcp Homeassistant
Connects Claude directly to your Home Assistant instance through its REST API. You get tools for reading and updating entity states, calling services, firing events, rendering Jinja templates, and pulling historical data from the logbook. It also exposes resources for browsing your current config, loaded components, and available services. Useful when you want Claude to control your smart home devices, query sensor data, or help debug automations without switching contexts. Requires a long-lived access token and supports Home Assistant 2026.4.1. Install via pip and configure with environment variables pointing to your HA instance.
