WHY IT NEEDS A POLICY

Why UpdateUsersSettings needs a policy

This tool modifies Multi-Factor Authentication settings for users, which is a Write action (reversible configuration change). However, severity is high because MFA is a critical security control; an AI agent disabling MFA for high-privilege accounts could compromise access controls and enable unauthorized authentication.

From the tool's definition 'Edit MFA settings' - modifies authentication configuration for user accounts, which is a reversible but critical security control.
