What create_role_hierarchy does on Discord MCP Server

AI agents use create_role_hierarchy to create or update resources in Discord MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Discord MCP Server environment.

WHY IT NEEDS A POLICY

Why create_role_hierarchy needs a policy

This tool creates new roles in a Discord server, which is a Write operation (creates data). Severity is high because: (1) roles control permissions across an entire server, (2) bulk creation in one operation amplifies the blast radius, (3) improper hierarchy could grant unintended permissions to many users, and (4) while reversible (roles can be deleted), the misuse could affect server security and user access…

From the tool's definition Tool creates multiple roles with hierarchy setup, which modifies Discord server structure irreversibly through a single operation.
