WHY IT NEEDS A POLICY

Why add_attacker needs a policy

This tool creates or adds attacker definitions to a threat modeling system—a reversible write operation. While the description is empty, the naming pattern and server context clearly indicate data creation rather than deletion, code execution, or financial impact.

From the tool's definition Tool name 'add_attacker' and sibling tools like 'add_asset', 'add_assumption', 'add_evidence' suggest CRUD operations on threat model data. The server description confirms it manages 'threat models' and related entities 'programmatically'.
