WHY IT NEEDS A POLICY

Why mittwald_login_token needs a policy

This tool authenticates a session using an API token, which creates/establishes an authenticated session state. It's a Write operation (creates a session/auth state) rather than purely Read. Misuse could allow unauthorized access to all resources available under that token, but the tool itself is the authentication step rather than a destructive or financial action.
