This server gives your AI agent tools to control Home Assistant. For better configurations, pair it with Home Assistant Agent Skills — domain knowledge that teaches the agent Home Assistant best practices.
An MCP server can create automations, helpers, and dashboards, but it has no opinion on how to structure them. Without domain knowledge, agents tend to over-rely on templates, pick the wrong helper type, or produce automations that are hard to maintain. The skills fill that gap: native constructs over Jinja2 workarounds, correct helper selection, safe refactoring workflows, and proper use of automation modes.
Want early access to new features and fixes? Dev releases (.devN) are published on every push to master.
