WHY IT NEEDS A POLICY

Why crear_documento needs a policy

This tool creates a new database/collection and inserts an initial document — a reversible write operation. It does not delete or overwrite existing data, execute arbitrary code, or involve financial transactions. Severity is medium because it can create new MongoDB databases and collections, which could lead to data sprawl or unintended schema creation, but the action is recoverable.
