Google opens Home devices to any MCP agent, from Claude to ChatGPT
Early access to a Google Home Model Context Protocol server lets agents review camera summaries, control Nest and Matter devices, and build custom dashboards after users grant permissions.
Google on Wednesday rolled out early access to a Model Context Protocol (MCP) server for the Google Home ecosystem. Any agent that supports MCP, including Claude, Hermes, OpenClaw, ChatGPT and Google Antigravity, can now work with a user's smart home devices and read their event history. With natural-language instructions, users can review camera summaries, monitor smart home activity, control connected devices and build their own custom dashboards. Supported hardware covers everything in the Google Home ecosystem, including Nest doorbells and thermostats as well as 'Works with Google Home' and Matter devices such as light bulbs. Setup is developer-flavored. Users create a Google Cloud project, configure it for Home MCP, hand the configuration details to their chosen agent and ask it to complete the connection. The agent then prompts them to sign in and grant permissions. A setup guide will be published in the Google Home Developer Center. Google already supports MCP across Google Cloud, its data platforms, developer tools and Workspace. The Home integration is aimed more directly at consumers experimenting with agents for everyday tasks. It also extends third-party agents, not just Google's own, into cameras, thermostats and other devices inside people's homes, which makes the permission-granting step and the choice of agent consequential for households that opt in.
