Google Opens Google Home MCP Server to Third-Party AI Agents
Around September 17, Google opened early access to its Google Home MCP server, letting third-party AI agents control Google Home devices directly via MCP, initially for US Google Home Premium Advanced subscribers. Agents move from suggesting actions to actually operating home hardware, raising questions around security and authorization.
Confirmed
- Any MCP-capable agent — Claude, ChatGPT, and per @krishnan also Hermes, OpenClaw, and Google's own Antigravity — can control smart homes in natural language: view camera summaries, monitor home activity, control lights and thermostats, and build custom dashboards
- Agents can actually operate devices and read home event history rather than just offering suggestions
- @armandruiz wired the MCP server into his @muse app, controlling all lights, cameras and thermostats via chat, and connected his PG&E utility account so the AI could check the electricity dashboard
Why it matters
- @sunychoudhary argues that agent use cases so far centered on code, email, calendar, browser and SaaS; smart homes mark a significant step for the MCP ecosystem
- @krishnan notes the opening also turns smart homes into an authorization challenge, as agents gain real control over devices and historical home data
