WHAT IT DOES

What cloak_interact does on Cloakbrowser

WHY IT NEEDS A POLICY

Why cloak_interact needs a policy

The tool name 'cloak_interact' combined with the server description mentioning 'interactive actions' strongly implies it performs browser interactions (clicks, form submissions, navigation, etc.) in a stealth browser. This is Execute-category behavior. The anti-detection/stealth aspect raises severity since misuse could facilitate scraping, credential stuffing, or other automated browser attacks.

From the tool's definition Tool name 'cloak_interact' on a server described as enabling 'interactive actions via natural language' using a stealth Chromium browser with anti-detection features.
