WebMCP tools
The Anomity Catalog lists 22 WebMCP tools, each scored 0–100 from declared trust, declared capabilities, and matched dangerous combinations. 1 score in the high or critical band; the median score is 30. Pages and browser tooling that hand agents callable tools inside the browser itself. The agent acts in a session that is already logged in — which is the whole point, and the whole risk.
