WHY IT NEEDS A POLICY

Why UpdateCreds needs a policy

This tool modifies (writes to) credential records, which are critical security assets. While Write category tools are typically lower risk, credentials are highly sensitive: unauthorized modification could compromise access control, enable privilege escalation, or redirect authentication. However, it is reversible (can be updated again), so it does not meet Destructive criteria.

From the tool's definition Tool name 'UpdateCreds' and description 'Edit an existing credentials record' indicate modification of sensitive authentication data without deletion or irreversible destruction.
