click_element · WebScout MCP: Risk & Policy

WHAT IT DOES

What click_element does on WebScout MCP

AI agents invoke click_element to trigger actions in WebScout MCP. 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 click_element needs a policy

This tool performs browser automation actions (clicking interactive elements) that trigger external operations with effects that depend on the target element — navigating pages, submitting forms, opening modals, or initiating conversations. The outcome varies entirely on what element is clicked, making it an Execute-category tool. Misuse could trigger unintended actions in web applications being reverse-engineered.
