# Model Context Protocol Server for Home Assistant
|
|
|
|
The server uses the MCP protocol to share access to a local Home Assistant instance with an LLM application.
|
|
|
|
A powerful bridge between your Home Assistant instance and Language Learning Models (LLMs), enabling natural language control and monitoring of your smart home devices through the Model Context Protocol (MCP). This server provides a comprehensive API for managing your entire Home Assistant ecosystem, from device control to system administration.
|
|

|

|
|

|
|

|
|
|
|
## Features
|
|
|
|
- 🎮 **Device Control**: Control any Home Assistant device through natural language
|
|
- 🔄 **Real-time Updates**: Get instant updates through Server-Sent Events (SSE)
|
|
- 🤖 **Automation Management**: Create, update, and manage automations
|
|
- 📊 **State Monitoring**: Track and query device states
|
|
- 🔐 **Secure**: Token-based authentication and rate limiting
|
|
- 📱 **Mobile Ready**: Works with any HTTP-capable client
|
|
|
|
## Real-time Updates with SSE
|
|
|
|
The server includes a powerful Server-Sent Events (SSE) system that provides real-time updates from your Home Assistant instance. This allows you to:
|
|
|
|
- 🔄 Get instant state changes for any device
|
|
- 📡 Monitor automation triggers and executions
|
|
- 🎯 Subscribe to specific domains or entities
|
|
- 📊 Track service calls and script executions
|
|
|
|
### Quick SSE Example
|
|
|
|
```javascript
|
|
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);
|
|
};
|
|
```
|
|
|
|
See [SSE_API.md](docs/SSE_API.md) for complete documentation of the SSE system.

|
## OpenAI Integration
|
|
|
|
The server includes powerful AI analysis capabilities powered by OpenAI's GPT-4 model. This feature provides intelligent analysis of your Home Assistant setup through two main modes:
|
|
|
|
### 1. Standard Analysis
|
|
|
|
Performs a comprehensive system analysis including:
|
|
- System Overview
|
|
- Performance Analysis
|
|
- Security Assessment
|
|
- Optimization Recommendations
|
|
- Maintenance Tasks
|
|
|
|
```bash
|
|
# Run standard analysis
|
|
npm run test:openai
|
|
# Select option 1 when prompted
|
|
```
|
|
|
|
### 2. Custom Prompt Analysis
|
|
|
|
Allows you to ask specific questions about your Home Assistant setup. The analysis can include:
|
|
- Device States
|
|
- Configuration Details
|
|
- Active Devices
|
|
- Device Attributes (brightness, temperature, etc.)
|
|
|
|
```bash
|
|
# Run custom analysis
|
|
npm run test:openai
|
|
# Select option 2 when prompted
|
|
```
|
|
|
|
### Configuration
|
|
|
|
To use the OpenAI integration, you need to set up your OpenAI API key in the `.env` file:
|
|
```env
|
|
OPENAI_API_KEY=your_openai_api_key
|
|
```
|
|
|
