Google lets third-party AI agents control smart home devices

The Model Context Protocol standardises how external agents interact with connected home systems.

Google is allowing third-party AI agents such as Claude and Open Claw to access, control and monitor connected smart home devices via a new integration called Google Home MCP. The move uses the standardised Model Context Protocol to let agents analyse home data and automate tasks.

What happened

Google announced Google Home MCP, a new integration enabling third-party AI agents to control and monitor smart home devices. The system uses the Model Context Protocol standard, allowing agents like Claude and Open Claw to access home data and manage connected devices.

Why it matters

Opening smart home control to third-party agents expands the potential use cases for AI assistants beyond chat interfaces and makes device control a multi-agent ecosystem rather than a walled garden. This standardisation via MCP reduces friction for developers building home automation features and increases interoperability across different AI platforms.

What changes

Developers can now build agents that manage smart homes without being locked into Google's own assistant, and consumers gain the ability to use their preferred AI agent to control their connected devices.
