WHY IT NEEDS A POLICY

Why firebase_create_web_app needs a policy

The tool creates a new Firebase web application resource, which is a reversible Write operation. While it adds a new entity to Firebase, it doesn't delete data, execute arbitrary code, or incur financial charges directly. Severity is medium because misconfiguration or unauthorized app creation could lead to security issues or increased service costs, but the action itself is not immediately destructive or financial.

From the tool's definition Tool name contains 'create' and description translates to 'Register new Web app in Firebase'. This creates a new application resource in Firebase.
