Today we are opening early access to Model Context Protocol (MCP) for Google Home, enabling AI Agents to safely interact with your Google Home. With Home MCP, any agent that supports calling MCP tools, such as Google Antigravity, Claude, Hermes, or Open Claw, can now interact with all of the devices and event history in the Google Home ecosystem, from your Google Home camera to your smart light bulbs.

This gives your favorite AI agent real-world physical context—allowing it to analyze and answer questions about home activity, summarize camera footage across rooms, manage devices on your behalf, or even create your own smart home dashboards using everyday language.

Here are some ways our early testers used Home MCP:

• Cross-Camera Analysis: Ask your agent what the kids did when they got home from school, and it will provide a summary across all of your cameras of what they did and show you the clips
• Analyze home history: Your agent can use your device state history to track how many loads of laundry were done in a week, or how long the lights were left on.
• Interact with you via voice: If your agent is completing an asynchronous or proactive task, it can send you an audio message over your Google Home speaker when it's finished.
• Build a dashboard: Your agent can build you a custom dashboard that provides a view of your smart home tailored just to you.

Starting today, early access is rolling out in English to Google Home Premium Advanced users in the US. To set up Home MCP, create a Google Cloud project and configure it to use Home MCP. Then simply provide the MCP configuration details to your agent and ask it to set it up. Your agent will ask you to sign in and grant permissions. After that, you're ready to go. For complete setup guides, visit the Google Home MCP Server page..

Connecting a real-life home to an AI agent allows that agent to control devices on your behalf. Home MCP enforces rate limits and safety protections, such as prohibiting sensitive actions like unlocking doors. However, depending on your agent, connecting it to Home MCP can result in unexpected or even undesired behavior. Carefully review developer policies and terms of service.

Today's early access launch is just the next step in unlocking agentic smart homes and we invite you to dive in and build with us. We'll be continuously adding more features for you to try, and we'd love your feedback in the Smart Home for Developers Help Community as we build a more helpful experience for all.
