WHAT IT DOES

What setup_channel_category does on Discord MCP Server

AI agents use setup_channel_category 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 setup_channel_category needs a policy

This tool creates new Discord channels and categories with associated permissions. While these operations are reversible (channels and categories can be deleted, permissions can be reset), they modify server state and structure. This is clearly a Write operation rather than Read (no data retrieval), Execute (not running arbitrary code), Destructive (creation, not deletion), or Financial (no monetary impact).

From the tool's definition Tool description states 'Create a category and its child channels in one operation' and 'set permission overwrites on the category'. The verbs 'Create' and 'set' indicate data modification. Permission overwrites are configuration changes that can be reverted.
