Google is rolling out early access to Model Context Protocol (MCP) for the Google Home ecosystem, allowing AI agents to securely control smart devices and access event history.

Initial access is limited to Google Home Premium Advanced subscribers in the US, priced at $20 per month or $200 per year, with a rollout planned over the coming weeks and requiring users to create or configure a Google Cloud project.

Supported devices include Nest cameras and doorbells, Nest Thermostats, and Matter-compatible light bulbs, enabling cross-device and cross-room interactions.

Bug fixes focus on Gemini for Home (Early Access), addressing follow-up questions, TV streaming issues, Gemini Live interruptions, broadcasts, and playlist playback, along with general stability improvements.

Author Tyler Lacoma previews potential benefits such as advanced automations and weather-integrated thermostat control, while noting concerns about dashboards and overall user experience.

The rollout acknowledges risks from third-party AI integration, including prompts-based attacks, and recalls historical Gemini prompt issues, urging caution in broad AI access.

Gemini may not be the default forever; users could choose Claude or another agent based on privacy, preferences, or integration needs, but final supported agents and switching methods are not yet disclosed.

FAQs indicate users can swap Gemini for Claude or another agent, but detailed controls, supported services, and launch timing remain unconfirmed.

Original reporting comes from TechCrunch, with context contributed by AI weekly news trackers.

Premium Advanced features include longer video history, descriptive notifications, detailed alerts, and enhanced video history search, among other tools.

This development fits a broader trend toward agents that perform actions and leverage services, raising questions about control, reliability, and who profits from household adoption.
