How smart home is becoming interface between AI agents and physical world

Google, Amazon, Samsung and Apple are connecting AI agents with smart home devices, making home platforms an increasingly important interface between AI and the physical world

Google has its own AI agent for the home. So does Amazon. Samsung is putting AI across its appliances, and Apple is connecting Apple Intelligence to the Home ecosystem.

That makes the question bigger than which company makes the best smart speaker or appliance. The competition is moving towards who becomes the control layer for an AI-powered home. That control layer determines which devices an agent can see, which information it can access and which actions it can take.

One of the clearer signs of this shift is Google opening its Home platform to other AI agents. It does this through what is called Model Context Protocol, or MCP, a standard that lets AI applications connect to and pull data from external systems. Google's Home MCP lets compatible agents such as Claude, ChatGPT and others access a Google Home setup, inspect connected devices, monitor their states, look at historical events and execute supported controls.

Google wants both the agent and the control layer

Google's position stands out because it isn't picking between building an AI agent and becoming infrastructure for other agents. It's doing both.
