Google Opens Home MCP to Third-Party AI Agents
Google has opened up its Home Model Context Protocol (MCP) server to third-party AI agents, including Claude and Anthropic's Cowork. This allows compatible agents to access authorized Google Home data and device controls.
The MCP system gives outside agents the ability to inspect devices, review past activity, and carry out supported commands after user grant access. Google's documentation lists five core capabilities: discovering homes, finding connected resources, checking current device states, reviewing historical events, and executing supported actions.
Claude is explicitly supported through its Cowork environment, where users can add Google Home as a custom connector and complete an OAuth authorization flow. Agents can also issue supported commands through the Home MCP action interface.
However, connecting an agent requires more than enabling a setting in the Google Home app. Users need a Premium Advanced subscription, a Google Cloud project, an MCP-compatible client, Home API access, and OAuth credentials. Google restricts some physical actions and warns that agents can behave unexpectedly.
