💬 What Can You Do With It?

Just talk to Claude naturally. Here are some real examples:

You Say	What Happens
"Create an automation that turns on the porch light at sunset"	Creates the automation with proper triggers and actions
"Add a weather card to my dashboard"	Updates your Lovelace dashboard with the new card
"The motion sensor automation isn't working, debug it"	Analyzes execution traces, identifies the issue, suggests fixes
"Make my morning routine automation also turn on the coffee maker"	Reads the existing automation, adds the new action, updates it
"Create a script that sets movie mode: dim lights, close blinds, turn on TV"	Creates a reusable script with the sequence of actions

Spend less time configuring, more time enjoying your smart home.

🧠 Better Results with Agent Skills

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.

Bundled Skills (built-in)

Skills from homeassistant-ai/skills are bundled and served as MCP resources via skill:// URIs. Any MCP client that supports resources can discover them automatically — no manual installation needed.

Setting	Default	Description
ENABLE_SKILLS	true	Serve skills as MCP resources. Resources are not auto-injected into context — clients must explicitly request them.
ENABLE_SKILLS_AS_TOOLS	true	Expose skills and doc resources via list_resources/read_resource tools. Resource-capable clients can set to false to reduce tool count.

Skills can still be installed manually for clients that prefer local skill files — see the skills repo for instructions.
