Breaking change (v7.3.0): ha_config_set_yaml has been moved to beta . HA-MCP — Manage Home Assistant with AI Configure and automate Home Assistant with Claude, ChatGPT, and other AI assistants. 🚀 Get Started The recommended way to run ha-mcp is the HA-MCP integration . It installs into Home Assistant through HACS (the built-in Marketplace on Home Assistant 2026.11+), 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: setup asks for an administrator access token and how clients may connect. Add it to Home Assistant via HACS or, on Home Assistant 2026.
