What is the Home Assistant MCP Server?
Connect to your Home Assistant instance (local or Nabu Casa cloud) and control your entire smart home from any AI agent. Manage lights, climate, media players, covers, switches, and trigger automations via the Home Assistant REST API.
What you can do
- Entity Discovery — List all entities and their current states across all integrations
- Device Control — Turn lights on/off, adjust brightness, set thermostat temperatures, open/close covers
- Service Calls — Call any Home Assistant service (light, switch, climate, cover, media_player, automation, script)
- State Monitoring — Get real-time state of any entity including sensors, binary sensors, and device trackers
- History & Logbook — Query historical state changes and logbook entries for analysis
- Calendar Management — List and query calendar events from Home Assistant calendars
- Event Automation — Fire custom events to trigger Home Assistant automations
- Template Rendering — Render Jinja2 templates for advanced state access
- Configuration — View system configuration, loaded components, and validate configuration
- Local or Cloud — Works with local instances (http://IP:8123) or Nabu Casa cloud (https://INSTANCE.ui.nabu.casa)
How it works
- Subscribe to this server
- Enter your Home Assistant URL and Long-Lived Access Token

Frequently asked questions
What Home Assistant URL should I use?
For local instances, use your Home Assistant's local network URL: http://YOUR_IP:8123 (or http://homeassistant.local:8123). For cloud access via Nabu Casa, use your remote URL: https://YOUR_INSTANCE.ui.nabu.casa. The API is accessible at the same base URL as your Home Assistant frontend.
How do I get a Long-Lived Access Token?
Log in to your Home Assistant web interface, go to your user profile (click your name in the sidebar, then Profile), scroll down to Long-Lived Access Tokens, click Create Token, give it a name (e.g., 'MCP Server'), and copy the generated token. This token never expires unless manually revoked.
What devices and integrations are supported?
All Home Assistant integrations are supported since the API works at the service/state level. This includes lights (Philips Hue, LIFX, etc.), thermostats (Nest, Ecobee, etc.), covers/blinds, switches, media players (Sonos, Chromecast, etc.), sensors, cameras, locks, vacuums, and 1000+ other integrations. Use list_entity_states to discover all available entities.
Can I trigger Home Assistant automations from the API?
Yes! You can trigger automations in multiple ways: 1) Call the automation.trigger service directly, 2) Fire a custom event using fire_ha_event that matches an event trigger in your automation, 3) Call the script.turn_on service to run scripts. You can also control devices directly which will trigger related automations.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
