🏠 Home Assistant MCP Server

🚀 Control your smart home through AI assistants in seconds. Manage lights, switches, sensors, climate, and media players. No coding, no custom server setup required.

Home Assistant is the most popular open-source home automation platform, connecting hundreds of smart device brands into one unified system. This MCP (Model Context Protocol) server lets AI assistants interact with your Home Assistant instance directly. It provides 5 tools (get_states, get_state, call_service, get_entities, get_services) and 2 resources (entities list, services list) so your AI can read sensor data, toggle lights, adjust thermostats, play media, and call any Home Assistant service.

The server runs in standby mode on Apify's infrastructure, meaning it stays active and responds instantly to requests. You provide your Home Assistant URL and a long-lived access token in each request body. There is no startup delay, no Docker containers to manage, and no port forwarding required. Just connect your AI assistant to this MCP endpoint and start controlling your smart home with natural language commands.

📋 What the Home Assistant MCP Server does

• 🔌 Get all entity states to see every device, sensor, and switch in your Home Assistant
• 🎯 Get specific entity state to check the current value of any sensor, light, or switch
• 🛠️ Call any service to toggle lights, set temperatures, play media, or trigger automations
• 📋 List all entities to discover available devices and their entity IDs
• 📚 List all services to see every action your Home Assistant supports
• 💰 Pay Per Event pricing so you only pay for the requests you make

The MCP server acts as a bridge between AI assistants and your Home Assistant instance. When your AI needs to check a temperature sensor, it calls the get_state tool with the entity ID. When it needs to turn on a light, it calls call_service with the appropriate domain, service, and entity. The server forwards these requests to your Home Assistant's REST API and returns the results to the AI.

💡 Why it matters: Without an MCP server, connecting an AI assistant to Home Assistant requires custom code, API wrappers, and server management. This actor handles all of that, giving your AI direct access to your smart home through a standard protocol.

⚠️ Good to Know: You need a running Home Assistant instance and a long-lived access token. Create the token at Profile > Long-Lived Access Tokens in your Home Assistant dashboard. Your Home Assistant must be accessible from the internet (or use a tunnel like Nabu Casa).

🚀 How to use
