Why It Matters
Google has previously implemented MCP in its Cloud, data platforms, developer tools, and Workspace services. The extension to Google Home aims to bring similar AI agent capabilities to consumer smart home ecosystems.
Smart home owners will soon be able to control their devices connected to Google Home via an AI agent. On Tuesday, Google rolled out early access to its Model Context Protocol (MCP) server for its Google Home ecosystem, which will allow any AI agent that supports MCP — like Claude, Hermes, OpenClaw, ChatGPT, and Google Antigravity — to securely work with their smart home devices and access their event history.
This update will allow people to use natural language instructions to do things like review their camera summaries, monitor smart home activity, control their connected devices, and build their own custom smart home dashboards.
To get the connection set up, users will need to create a Google Cloud project and configure it to use Home MCP. They will then provide the MCP configuration details to their agent of choice and ask it to set it up. The agent will then ask them to sign in and grant permissions. (A setup guide will also be offered in the Google Home Developer Center).
The system will support any device in the Google Home ecosystem, including Google Nest doorbells and thermostats, and “Works with Google Home” (or Matter) devices, like light bulbs.
Google already supports MCP in other areas of its business, including in its Google Cloud and data platforms, developer tools, and Google Workspace, for instance. Support for Google Home is targeted more directly at consumers who are experimenting with AI agents designed to handle everyday tasks.
The company said access to the MCP will roll out starting today and continuing over the coming weeks to subscribers who pay for Google Home Premium Advanced in the U.S. This is the more expensive, $20-per-month subscription tier that provides features like longer event-based video history, descriptive notifications and detailed alerts, tools to search video history, daily summaries, and more.
Google wouldn’t comment on if or when the MCP would roll out more broadly, such as to other subscription tiers or markets.
What to Watch
