cloak_click · CloakBrowser MCP Server MCP: Risk & Policy

WHAT IT DOES

What cloak_click does on CloakBrowser MCP Server

AI agents invoke cloak_click to trigger actions in CloakBrowser 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 cloak_click needs a policy

Clicking an element in a browser triggers external operations whose effects depend on what is clicked — form submissions, navigation, button actions, purchases, etc. This is a browser interaction/execution action, not a simple read or write to a data store. Severity is medium because the impact depends entirely on the target element, but misuse could trigger significant actions.
