Google Lets AI Agents Control Smart Home Devices Directly

Google opens its Home platform to third-party AI agents through Home MCP, allowing compatible assistants to discover devices, access activity data, and control connected home products through natural-language commands.

Through an integration known as Model Context Protocol (MCP), Google is making its smart-home ecosystem open to more AI agents. The third-party AI agents that can be integrated with Google Home can directly communicate with the devices that are connected with Google Home via the Home MCP server.

It allows the artificial intelligence (AI) agents to identify connected devices, verify their state, access their past activities, and command them. This allows a person to control several parts of their home through AI agent interaction by natural language, instead of doing everything from individual applications and commands for each device separately.

Google’s solution works with multiple devices in its Google Home ecosystem that includes Nest products and devices that support “Works with Google Home” or Matter. Possible uses include verifying if the lights are turned on and viewing what happens in your house using security cameras, as well as managing appliances.

One critical feature of this innovation is that it is capable of connecting to third-party AI agents. The company has already found some MCP-capable clients such as Anthropic’s Claude and their own Antigravity, while the MCP platform itself can connect other MCP-capable AI assistants to Google Home.

The feature also makes interaction in the smart homes even more sophisticated since AI can use data from multiple gadgets in a household to perform a task. Google continues to work on other features, and one of them is the development of capabilities for managing smart home automations using MCP.

Some operations, such as opening doors, have become restricted. There are also constraints imposed on how often these AI agents can communicate with connected devices. Additionally, it has been pointed out by Google that AI agents may provide unpredictable outcomes when they gain access to devices in reality.

Home MCP can be accessed through an early access program that needs a Google Home Premium Advanced subscription in the US and also a Google Cloud project and an MCP client. The launch will therefore mainly focus on those users exploring advanced AI agent features rather than the wider smart home market.

The program reinforces Google's role as the foundational platform for AI-driven smart-home communications. With the inclusion of third-party agents for Google Home devices and information, Google is taking steps towards establishing itself in a manner whereby AI acts as a mediator between consumers and their increasingly interconnected homes.
