Integrations

  • Allows to interact with Home Assistant devices, including getting device states, controlling device states (on/off), triggering automations, and listing available entities

Home Assistant MCP Server

A Model Context Protocol (MCP) server for interacting with Home Assistant. This server provides tools to control and monitor your Home Assistant devices through MCP-enabled applications.

This project is part of the AI Model Context Protocol (MCP) ecosystem. For more information and documentation about MCP tools, visit www.aimcp.info.

Features

  • Get device states
  • Control device states (on/off)
  • Trigger automations
  • List available entities

Installation

  1. Clone this repository:
git clone https://github.com/yourusername/homeassistant-server-mcp.git cd homeassistant-server-mcp
  1. Install dependencies:
npm install
  1. Build the project:
npm run build
  1. Configure the MCP server by adding the following to your MCP settings file (typically located at ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json for VSCode):
{ "mcpServers": { "homeassistant": { "command": "node", "args": ["/path/to/homeassistant-mcp/homeassistant-server/build/index.js"], "env": { "HA_URL": "http://your-homeassistant-url:8123", "HA_TOKEN": "your-long-lived-access-token" } } } }

Replace your-homeassistant-url and your-long-lived-access-token with your Home Assistant instance URL and access token.
