Google is extending its smart home ecosystem to support external AI agents and chatbots by adopting the Model Context Protocol (MCP), an industry-standard framework for integrating AI assistants with external systems and devices. This integration enables AI platforms—including Claude, Google Antigravity, Hermes, and Open Claw—to interact directly with connected smart home devices and access historical event data, expanding the range of interfaces through which users can manage their homes.

The shift allows homeowners to control their smart devices, monitor security cameras, and track household activity using conversational, natural-language commands through whichever AI assistant they prefer. Rather than locking users into a single vendor's ecosystem, Google's adoption of the open MCP standard signals a broader industry trend toward interoperability, giving consumers greater flexibility in choosing and combining AI tools with their existing smart home infrastructure.
