tevonsb/homeassistant-mcp

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
See SSE_API.md for complete documentation of the SSE system.
