Google is opening its smart home platform to third-party AI agents. A new integration called Google Home MCP lets any agent that supports the Model Context Protocol (MCP) reach the devices and event history in a user's Google Home ecosystem.

In a blog post, Taylor Lehman, group product manager at Google Home & Nest, said the integration covers MCP-capable agents including Google Antigravity, Claude, Hermes and Open Claw.

## What it does

Lehman's examples include cross-camera analysis, so a user can ask an agent what their child did after coming home from school. Device state history can answer how many loads of laundry were run last week or how long the lights stayed on. An agent can also speak back through a Google Home speaker, for instance with an audio message once a task is done, and it can build a custom dashboard for controlling the home.

The integration does not replace Gemini for Home, which remains Google's interface inside the Home app and on Nest speakers. MCP adds a separate control layer that third-party agents use through their own interfaces.

## Access and safeguards

At launch, access is limited to Google Home Premium Advanced subscribers in the US, priced at $20 per month or $200 per year, rolling out over the coming weeks. Setup requires creating a Google Cloud project and configuring it for Home MCP.

Google says Home MCP enforces rate limits and safety protections, and that an agent will not be allowed to unlock doors. Lehman still warns that depending on the agent, connecting it to Home MCP "can result in unexpected or even undesired behavior," and points developers to Google's policies and terms of service.

The open-source Home Assistant platform already ships a similar MCP integration. For Google, the move extends a developer push that began with smart home API access in 2024.
