Google has opened a new door for AI agents to interact with smart homes. The company rolled out early access to its Model Context Protocol server for Google Home this week.
The update means outside AI agents can now securely connect to a person's smart home setup. This includes tools like Claude, ChatGPT, Hermes, OpenClaw, and Google Antigravity.
Once connected, these agents can carry out tasks using plain language. That includes reviewing camera summaries or checking a home's event history.
How the Setup Works
Getting connected requires a few steps. Users first need to create a Google Cloud project.
That project then has to be configured to use Home MCP. After that, the configuration details get passed along to whichever AI agent the person wants to use.
The agent handles the rest of the setup process. It will prompt the user to sign in and approve the necessary permissions.
Google also plans to publish a setup guide. It will be available through the Google Home Developer Center for anyone who needs help along the way.
The system is built to support a wide range of hardware. This includes Google Nest doorbells and thermostats.
It also covers any device labeled "Works with Google Home." That includes Matter-certified products, such as smart light bulbs from other brands.
Who Gets Access First
This is not Google's first move into the MCP space. The company already supports the protocol across other parts of its business.
That includes Google Cloud, various data platforms, and developer tools. Google Workspace also uses MCP for similar integrations.
The Google Home version is aimed at a different group. It targets everyday consumers who are testing AI agents for daily household tasks.
For now, access is limited. Only subscribers to Google Home Premium Advanced in the United States can use the new feature.
That subscription costs $20 per month. It includes extras like longer video history, detailed alerts, and daily summaries.
Google has not said if or when the feature will expand. That includes whether it will reach other subscription tiers or additional countries.
The company is collecting feedback from early users right now. That feedback comes through its Smart Home for Developers Community page.
Google did correct one detail after the initial announcement. The rollout began on Wednesday, September 16, not Tuesday as first stated.
