Your AI Agents Can Now Control Your Google Home Devices

Google just opened a door that could turn your smart home into something your AI agent actually runs for you. On Tuesday, the company rolled out early access to a Model Context Protocol (MCP) server for its Google Home ecosystem — meaning any AI agent that supports MCP, from Claude and ChatGPT to Hermes, OpenClaw, and Google's own Antigravity, can now securely work with your connected devices and pull up their event history.

In practice, that means you can use natural language to ask your agent to review camera summaries, monitor smart-home activity, control connected devices, or even build you a custom smart-home dashboard. "What happened at my front door today?" stops being a phone-app chore and becomes a sentence you type to whatever agent you already use.

How the hookup works

It's not quite plug-and-play yet. To set up the connection, users need to create a Google Cloud project, configure it for Home MCP, and hand the MCP configuration details to their agent of choice. The agent then walks them through signing in and granting permissions. Google says a setup guide will be available in the Google Home Developer Center, and the company is actively soliciting feedback from early adopters through its Smart Home for Developers Community during the early-access period.

The server supports the full Google Home ecosystem: Nest doorbells and thermostats, plus "Works with Google Home" and Matter devices like smart bulbs.

The $20-a-month catch

Here's the gating detail: access is rolling out starting today and over the coming weeks only to subscribers of Google Home Premium Advanced in the U.S. That's the $20-per-month tier — the one that already includes longer event-based video history, descriptive notifications, detailed alerts, video-history search, and daily summaries. Google wouldn't say if or when the MCP server reaches other tiers or markets, so for now the agent-powered smart home is a premium feature.

The bigger play

Google already supports MCP across its developer-facing businesses — Google Cloud, its data platforms, developer tools, and Google Workspace. The Home rollout is the consumer-facing move, and it lands right where a wave of people are experimenting with AI agents for everyday tasks. If MCP becomes the standard plumbing between agents and the physical world, Google just claimed one of the most valuable endpoints: the home itself.

The open question is whether consumers will follow. Tying the launch to the priciest subscription tier keeps the audience small by design — early access in the truest sense. But if agents-as-smart-home-operators stick, this looks like the first step toward a world where your home runs on conversation, not apps.
