Google Home is getting support for the Model Context Protocol (MCP) standard. This means users will be able to use a variety of AI agents to complete smart home tasks, as MCP is a software platform that lets agentic chatbots connect to external APIs.

Supported agents include Google Antigravity, Claude, Hermes and Open Claw, among others. Google says the integration will let these agents "securely work with all of the devices and event history in your Google Home ecosystem." Use cases include using natural language to monitor activity, review camera summaries across rooms, control connected devices and build custom smart home dashboards.

An early access build will arrive in the "coming weeks," but only for Google Home Premium Advanced users. That subscription costs $20 per month or $200 each year. Anthropic introduced MCP back in 2024 and it's become somewhat popular. Google, Open AI, Microsoft and Space XAI all support it in some form.

Many experts have warned that MCP has serious security flaws, like a lack of enforced authentication, leading to data breaches. Be careful out there.
