WHY IT NEEDS A POLICY

Why identities_create needs a policy

This tool creates new identity records for AI agents. While creation is a Write (reversible) operation rather than Destructive, the medium severity reflects that identity creation could enable unauthorized agent personas or credential abuse if exploited. The confidence is slightly reduced due to the truncated description, but the intent is unambiguous.

From the tool's definition Tool name 'identities_create' and context describing it creates 'a new agent identity' with server purpose of managing 'identity infrastructure for AI agents'.
