Google has launched early access to its Model Context Protocol (MCP) server for the Google Home ecosystem, allowing compatible AI agents to control smart home devices. This rollout began on Tuesday for Google Home Premium Advanced subscribers in the U.S.
The update enables AI agents like Claude, Hermes, OpenClaw, ChatGPT, and Google Antigravity to securely interact with smart home devices and access event history. Users can employ natural language to review camera summaries, monitor smart home activity, control connected devices, and create custom smart home dashboards.
To set up the connection, users need to create and configure a Google Cloud project for Home MCP, then provide these details to their chosen AI agent. The system supports all devices within the Google Home ecosystem, including Google Nest products and "Works with Google Home" (or Matter) devices.
Access to MCP is rolling out to Google Home Premium Advanced subscribers, a $20-per-month tier offering features such as extended video history and detailed alerts. Google is also seeking feedback from early adopters through its Smart Home for Developers Community.
