WHAT IT DOES

What chrome_click_element does on Chrome MCP Server

AI agents invoke chrome_click_element to trigger actions in Chrome MCP Server. 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 chrome_click_element needs a policy

Clicking elements in a browser is an Execute-category action because its effects are entirely argument-dependent. A click could submit a form, confirm a deletion, initiate a financial transaction, or navigate to a new page. An AI agent misusing this tool could cause significant unintended actions across any website the browser has access to, warranting high severity.

From the tool's definition 'Click elements using CSS selectors' — triggers browser UI interactions that can submit forms, navigate pages, initiate purchases, or activate any clickable element
