Analysis summary

WebMCP Smart Home is an officially published WebMCP tool from GoogleChromeLabs. Anomity scores its risk at 10 out of 100 (low).

A smart-home dashboard that reveals camera, climate, and energy controls as WebMCP tools, and lets an agent rearrange the dashboard as well as operate it. The demonstration extends past reading state into changing the physical environment.

This is the high-consequence end of the reference set, and worth catalogued attention for that reason alone. Tools that unlock, disarm, or view cameras are not recoverable the way a shopping cart is, and the agent invoking them is reading a page whose content may not be fully trusted. It declares browser control and outbound network access. Any real deployment of this shape needs per-tool authorization that is independent of the agent's context — the model should be able to request the action and still not be able to perform it unattended.
