Home Assistant MCP Server

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

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:
