WHAT IT DOES

What discord_create_forum_channel does on Discord

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

WHY IT NEEDS A POLICY

Why discord_create_forum_channel needs a policy

This tool creates a new Discord forum channel, which is a reversible modification to server structure. It does not execute arbitrary code, delete data, or move money. The severity is medium because creating channels can disrupt server organization but can be reversed by deletion. This is characteristic of Write operations rather than Execute (no code running) or Destructive (reversible action).

From the tool's definition Tool description states 'Create a new forum channel in a server' and 'Returns the new channel', indicating creation of a new resource. Requires 'Manage Channels permission', confirming it modifies server structure.
