Google Home MCP Opens Early Access to AI Agents
Google has opened up its Model Context Protocol (MCP) server to early access for Google Home Premium Advanced users. This allows compatible AI agents to inspect a home, read live device state, and run supported commands.
The MCP server is not a new speaker firmware but rather a remote endpoint at home.googleapis.com that can be accessed by an agent that speaks MCP. Agents can use five tools: listing homes, devices, and rooms; reading live states; running actions; and pulling history.
Google has provided example clients, including Google Antigravity, Claude Cowork, and OpenClaw, which demonstrate the capabilities of the MCP server. Users can revoke access in the Google Home app or on the My Accounts page, but Google warns that connecting a real-life home to an AI agent allows that agent to control devices on behalf.
Setup is not straightforward and requires creating a Cloud project, enabling the Home API, publishing an OAuth client, and pasting credentials into the agent. Google also notes that wrong agents can produce unexpected or unwanted behavior, and users should be cautious when setting up their home's MCP server.
