AI agents call metube_cookie_status to retrieve information from Metube without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration status information about cookies without creating, modifying, or deleting any data. It is a pure read operation that queries the current state of cookie authentication settings. The low severity reflects that misuse only exposes whether authentication is configured, with no blast radius for unintended downloads or system changes.
