Google Opens AI Agent Access to Home Devices, Enabling Claude and ChatGPT to Control Nest

Google has officially opened early access to its Model Context Protocol (MCP) server for the Google Home ecosystem, allowing AI agents that support the protocol—including Claude, ChatGPT, and Hermes—to control smart home devices via natural language instructions. This move marks a significant shift in AI adoption within the consumer sector, as similar protocols were previously only utilized in enterprise environments.

This integration enables users to issue simple commands to review camera summaries, monitor home activity, control devices, and even build custom dashboards. Support extends to devices within the Google Home ecosystem, such as Nest doorbells and thermostats, as well as "Works with Google Home" or Matter-certified devices like smart lights. However, the setup process is not instant: users must create a Google Cloud project, configure Home MCP, then provide configuration details to their chosen agent and prompt the agent to complete the setup.

This rollout is still limited. Google stated that access began last Wednesday and will continue over the next few weeks, but only for Google Home Premium Advanced subscribers in the United States. This tier is priced at $20 per month and offers features such as longer event-based video history, descriptive notifications, and daily summaries. Google has not yet confirmed if or when MCP will be available in other subscription tiers or international markets.

This move expands the use of MCP, which has primarily targeted technical and enterprise products. By bringing it to Google Home, Google aims at consumers who are beginning to experiment with AI agents for daily tasks. The company has also opened a feedback channel through the Smart Home for Developers Community for early adopters.

"We want to see if this feature will expand beyond the premium tier and the US market," a Google spokesperson said, without providing a specific timeline.

For Indonesia, this development raises questions about infrastructure and regulatory readiness. Although smart home devices are increasingly popular in major cities, the adoption of AI agents for device control is still hampered by limitations in the local ecosystem and data protection policies. If Google expands this feature to global markets, Indonesian users could enjoy similar conveniences, but clarity on data privacy and security would be essential.

Looking ahead, will Google open MCP to all users or keep it exclusive to premium subscribers? The answer to this question will determine how quickly AI integration in households becomes a new standard, rather than just a luxury feature.
