⚠️ Breaking change in OAuth (beta) mode — v7.0.0 requiresHOMEASSISTANT_URLto be set server-side. See issue #749 for migration instructions.
A comprehensive Model Context Protocol (MCP) server that enables AI assistants to interact with Home Assistant.
Using natural language, control smart home devices, query states, execute services and manage your automations.

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 |

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.
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 |
false |
Also expose skills via list_resources/read_resource tools for clients that don't support MCP resources natively. |
Skills can still be installed manually for clients that prefer local skill files — see the skills repo for instructions.
