browser_click · Browser Pool MCP: Risk & Policy

WHAT IT DOES

What browser_click does on Browser Pool

AI agents invoke browser_click to trigger actions in Browser Pool. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why browser_click needs a policy

Clicking a browser element is an action whose consequences depend entirely on the target element and page. It can trigger form submissions, navigation, purchases, deletions, or other irreversible operations. This is an Execute-category action with high severity due to the broad blast radius of arbitrary click actions in a browser session.

From the tool's definition 'Click element' — triggers browser UI interactions that can submit forms, initiate downloads, trigger payments, delete data, or cause other side effects depending on the page context
