WHY IT NEEDS A POLICY

Why wp_user_create needs a policy

This tool creates a new user account in WordPress, which is a reversible modification operation (users can be deleted). It does not execute arbitrary code, trigger financial transactions, or permanently destroy data. However, it carries medium severity because an unauthorized user creation could grant unintended access to a WordPress instance, potentially compromising site security depending on the role assigned.

From the tool's definition Tool name is 'wp_user_create' with description 'Create a new user'. The 'create' verb and explicit user creation purpose indicate a Write operation that adds new data to the WordPress user system.
