# Google Home MCP lets Claude and OpenClaw control Home devices

> Google opened Home MCP to Claude, OpenClaw, and other agents for U.S. Premium Advanced homes; door unlocks are blocked and Google warns the wrong agent can still misbehave.

Google has opened early access to a Home MCP server, letting third-party AI agents read a Google Home’s devices and history and send commands. The rollout began September 16, 2026 for Google Home Premium Advanced subscribers in the United States.

Taylor Lehman, group product manager at Google Home & Nest, said the integration “allows any AI agents that support MCP, including Google Antigravity, Claude, Hermes or Open Claw, to securely work with all of the devices and event history in your Google Home ecosystem.” Google’s developer documentation names Google Antigravity, Claude Cowork, and OpenClaw as example clients. TechCrunch also listed Hermes and ChatGPT among MCP-capable agents.

A connected agent can discover homes and devices, check live trait state, run parameterized actions, and query event history. Lehman’s examples include asking what a child did after school across cameras, counting laundry loads or lights-on time from device history, and pushing an audio message through a Google Home speaker when a long task finishes. TechCrunch reports agents can also build custom dashboards. Compatible hardware includes Nest doorbells and thermostats plus Matter or “Works with Google Home” devices such as light bulbs.

Access is rolling out over the coming weeks to the $20-per-month Premium Advanced tier in the U.S. Google would not say whether other subscription tiers or markets will follow. Setup is not a toggle in the Home app. Users create a Google Cloud project, enable the Home API, configure OAuth consent and credentials, then hand a client ID and secret to their agent. Access can be revoked from the Google Home app or a My Accounts page.

Google’s docs put a hard warning next to the tools. Connecting a real-life home to an AI agent “allows that agent to control devices on your behalf.” Home MCP enforces rate limits and blocks sensitive actions such as unlocking doors. Even so, “depending on your agent, connecting it to Home MCP can result in unexpected or even undesired behavior.” If a home is shared, Google says the rest of the household should know the agent can control devices and read home data; a separate home for testing is the suggested alternative. Familiar-face data needs a second, separate consent. Automations cannot be created or managed through Home MCP yet. Google also flags latency and experimental device traits as known issues.

If you already pay for Premium Advanced in the U.S. and run an MCP client you trust, start with Google’s Home MCP setup guide—last updated September 15, 2026—and treat the safety warning as part of the product, not a footnote.
