Google opens Google Home to third‑party AI agents via Model Context Protocol (MCP)
Google Home now supports a Home MCP integration using the Model Context Protocol that lets third‑party AI agents (e.g., Claude, OpenClaw, Hermes, Google Antigravity) access device state and event history, control supported devices (with enforced safety limits), build custom dashboards, and interact via voice. The feature is initially limited to Google Home Premium Advanced users in the US, requires creating a Google Cloud project, and Google warns agents can produce unexpected behavior despite rate limits and protections (e.g., agents are not allowed to unlock doors).
