Overview

The MCP Server bridges Home Assistant with advanced LLM integrations to deliver intuitive control, automation, and state monitoring. Leveraging a high-performance runtime and real-time communication protocols, MCP offers a seamless experience for managing your smart home.

Key Features

Device Control & Monitoring

• Smart Device Control: Manage lights, climate, covers, switches, sensors, media players, fans, locks, vacuums, and cameras using natural language commands.
• Real-time Updates: Receive instant notifications and updates via Server-Sent Events (SSE).

System & Automation Management

• Automation Engine: Create, modify, and trigger custom automation rules with ease.
• Add-on & Package Management: Integrates with HACS for deploying custom integrations, themes, scripts, and applications.
• Robust System Management: Features advanced state monitoring, error handling, and security safeguards.

Architecture & Design

The MCP Server is built with scalability, resilience, and security in mind:

• High-Performance Runtime: Powered by Bun for fast startup, efficient memory utilization, and native TypeScript support.
• Real-time Communication: Employs Server-Sent Events (SSE) for continuous, real-time data updates.
• Modular & Extensible: Designed to support plugins, add-ons, and custom automation scripts, allowing for easy expansion.
• Secure API Integration: Implements token-based authentication, rate limiting, and adherence to best security practices.

For a deeper dive into the system architecture, please refer to our Architecture Documentation.

Usage

Once the server is running, open your browser at http://localhost:3000. For real-time device updates, integrate the SSE endpoint in your application:

const eventSource = new EventSource('http://localhost:3000/subscribe_events?token=YOUR_TOKEN&domain=light');

eventSource.onmessage = (event) => {
  const data = JSON.parse(event.data);
  console.log('Update received:', data);
};
