Anthropic built MCP. Google is now betting its smart home platform on it. That’s either a sign that the Model Context Protocol has arrived as a serious infrastructure standard, or that everyone is moving too fast. Probably both.
Google announced that Google Home is getting native MCP integration, allowing AI agents to connect directly to your smart home devices, camera history, and event logs. Supported agents include Google Antigravity, Claude, Hermes, and Open Claw. The idea is that you talk to an agent in natural language, and it handles the home automation layer. Monitor camera feeds, control devices, build custom dashboards, all through conversational commands rather than app menus.
This matters because it signals that MCP is moving from developer experiment to mainstream consumer product. Anthropic introduced the protocol in 2024, and adoption has been fast. Google, OpenAI, Microsoft, and SpaceXAI all support it in some form. MCP essentially gives agentic systems a standardized way to call external APIs, which means a single agent can talk to your thermostat, your security camera, and your lights without custom integrations for each. That’s the real value here. Not any one agent, but the shared plumbing.
For Google specifically, this is also about making Google Home stickier. The smart home market is competitive. Amazon’s Alexa ecosystem is massive, Apple HomeKit has strong hardware integration, and Matter as a connectivity standard is already doing some of what MCP aims to do at a device level. Adding agentic AI on top of Google Home is a push to differentiate on intelligence rather than just device compatibility.
But the security question is not minor. Multiple researchers have flagged that MCP lacks enforced authentication standards, and that gap has already contributed to real data breaches since broader adoption began. Giving an AI agent access to your camera history and home activity logs is a meaningful attack surface. Google says agents will “securely work” with your ecosystem, but the protocol itself does not guarantee that by design.
Early access goes to Google Home Premium Advanced subscribers first, at $20 per month or $200 per year. That’s a deliberate choice to test with a smaller, paying user base before wider rollout. Smart, given the risks. Still, anyone connecting AI agents to home security cameras should understand what they’re opting into. The convenience is real. So is the exposure.
