Summary
Google began early access to a Model Context Protocol (MCP) server for the Google Home ecosystem, letting any MCP-capable AI agent, including Claude and ChatGPT, read device state, review camera and activity summaries, control connected devices, and build custom smart-home dashboards in natural language. Early access opened to Google Home Premium Advanced subscribers in the US, rolling out over the coming weeks.
What changed
Google shipped an MCP server for Google Home in early access, exposing device state, event history, camera summaries, and device control to external AI agents that speak MCP, set up via a Google Cloud project and agent-side permission grants.
Why it matters
Consumer smart-home platforms have largely kept AI assistants inside their own apps; opening Home over MCP turns a major device ecosystem into a tool surface any agent can call. It signals MCP hardening as the default interoperability layer between third-party agents and first-party platform data.

allow any AI agent that supports MCP -- like Claude, ChatGPT and others -- to securely work with their smart home devices.
