A Model Context Protocol (MCP) server project that integrates with Home Assistant to provide smart home control capabilities.
The server provides prompts for each domain's set of tools.
The server implements control for various Home Assistant domains. Currently supports:
- 💡 Lights: Turn on/off, brightness control
- 🌡️ Climate: Temperature control, HVAC modes
- 🔒 Locks: Lock/unlock functionality
- 🚨 Alarm Control Panel: Arm/disarm security systems
- 💧 Humidifier: Humidity control
Example tools include:
light-turn_on()
climate-turn_off()
alarm_control_panel-disarm()
lock-lock()
humidifier-turn_off()
Create a .env file in the root directory with:
HOMEASSISTANT_TOKEN=your_long_lived_access_token_here # get it from your Home Assistant instance after onboarding
HOMEASSISTANT_BASE_URL=your_home_assistant_url_here # e.g. http://homeassistant.local:8123
Follow the instructions on how to install Home Assistant and get a long lived access token.

Development/Unpublished Servers Configuration
``` "mcpServers": { "home-assistant-server": { "command": "uv", "args": [ "--directory", "/path/to/home-assistant-server", "run", "home-assistant-server" ] } } ```Published Servers Configuration
``` "mcpServers": { "home-assistant-server": { "command": "uvx", "args": [ "home-assistant-server" ] } } ```To prepare the package for distribution:
- Sync dependencies and update lockfile:
uv sync- Build package distributions:
uv buildThis will create source and wheel distributions in the dist/ directory.
- Publish to PyPI:
uv publishNote: You'll need to set PyPI credentials via environment variables or command flags:
- Token:
--tokenorUV_PUBLISH_TOKEN - Or username/password:
--username/UV_PUBLISH_USERNAMEand--password/UV_PUBLISH_PASSWORD
Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the MCP Inspector.
You can launch the MCP Inspector via npm with this command:
npx @modelcontextprotocol/inspector uv --directory /Users/miguel/Documents/home-assistant-server/home-assistant-server run home-assistant-serverUpon launching, the Inspector will display a URL that you can access in your browser to begin debugging.
