Google will now let any AI agent run your smart home

Google just made a significant move in the AI agent wars by opening Google Home to third-party AI assistants through the Model Context Protocol. According to The Verge, tools like Claude and other MCP-compatible agents can now directly access, control, and monitor your smart home devices without going through Google's own Assistant.

This is bigger than it sounds. Until now, your smart home was essentially locked to whatever AI came with it. Google Assistant controlled Google Home, Alexa controlled Amazon devices, and so on. By adopting MCP, a standardized protocol for AI agent communication, Google is treating your home like an open platform where any capable AI can operate.

The practical implications are immediate. An AI agent could now analyze your home's event history, spot patterns in your energy usage, adjust your thermostat based on your actual behavior rather than a preset schedule, or coordinate multiple devices in ways the native Google Assistant never considered. Taylor Lehman, group product manager at Google Home & Nest, confirmed the integration works with Google's own Antigravity agent as well as Claude, Hermes, and Open Claw.

This move signals where the smart home is heading: away from siloed voice assistants and toward autonomous agents that can genuinely reason about your home environment. It also puts pressure on Apple and Amazon to either adopt MCP or risk becoming the walled gardens while Google becomes the open platform.

The timing matters too. We are entering the era of agentic AI, where assistants do not just respond to commands but take initiative. A smart home that any agent can access becomes exponentially more useful because you are not limited by what one company decided to build.

What this means for you: If you have a Google Home setup and use Claude or another MCP-compatible AI tool, you can now give it much deeper control over your environment. Try this prompt with Claude: "Analyze my Google Home event history for the past month and suggest three automation routines that would save energy or improve my daily routine, then create them." You are essentially turning your AI assistant into a smart home consultant that can act on its own recommendations.
