Google Home Cedes Control — Third-Party AI Agents Can Now Run Your House

Google is opening its smart home ecosystem, allowing third-party AI agents like Claude and ChatGPT to directly control your connected lights, cameras, and thermostats. The change, reported by TechCrunch and The Verge, marks a fundamental pivot from the walled garden of Google Assistant to a more open, and potentially more chaotic, future for the connected home.

The new capability is powered by a new server for Google Home that uses the Model Context Protocol (MCP), a standard designed to let AI models interact with external devices and data sources. Instead of being limited to Google's own AI, your home can now be run by any compatible agent. This means you could ask an AI like Claude to perform complex tasks that go beyond simple commands, such as monitoring your home and acting on what it observes.

An Open Platform in a Locked-Down World

For years, the smart home has been a battle of closed systems. Apple has HomeKit, Amazon has Alexa, and Google has Google Assistant. Your choice of platform dictated which devices you could use and what AI you could talk to. Google is now breaking that model.

By adopting the MCP standard, Google is positioning Home not as the single brain, but as the central nervous system that other brains can plug into. According to TechCrunch, these agents can control devices, review summaries from cameras, and access general smart home activity using natural language prompts. This could enable far more sophisticated automation than what's possible with the simple routines offered today. Imagine asking an AI to “keep an eye on the garden and turn on the sprinklers for 10 minutes if the soil moisture sensor drops below 30% and it hasn't rained in 24 hours.” That level of conditional logic has been the missing piece for many smart home enthusiasts.

This move is a classic Google playbook entry, reminiscent of Android's open strategy versus Apple's closed iOS. Google is betting that an open platform will attract more developers and create more powerful use cases, even if it means ceding some control over the user experience.

Early Access for Power Users

Before you rush to connect ChatGPT to your thermostat, the rollout will be limited. Engadget reports that an early access build is being made available to “Premium Advanced users” within the “coming weeks.” This detail suggests Google is treading carefully, using a small group of power users to test the system before any wider release.

The initial group of supported AIs includes Claude and, as The Verge notes, Open Claw, with TechCrunch also mentioning ChatGPT. This isn't a single-partner deal; it's the opening of a door. The immediate experience will depend entirely on the capabilities of the third-party agent. A powerful, context-aware AI could make the smart home feel truly intelligent. A less capable one could create frustrating or unpredictable behavior.

The pattern indicates Google is acknowledging a simple truth: its own Assistant is no longer the most powerful AI on the block. Rather than fight a losing battle to keep users within its own AI, Google is choosing to become the essential hardware and software layer that all other AIs will want to run on. The risk is that this introduces new security vulnerabilities and privacy headaches. When a third-party AI has access to your camera feeds and door locks, the question of liability becomes incredibly complex.
