discord_create_channel · Discord MCP: Risk & Policy

WHAT IT DOES

What discord_create_channel does on Discord

AI agents use discord_create_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_channel needs a policy

This tool creates new channels in a Discord server, which is a reversible modification of server data. While it changes the server state, the action can be undone by deleting the created channel. This is characteristic of Write category tools rather than Destructive (channels can be deleted) or Execute (not running arbitrary code).

From the tool's definition Tool description states it will 'Create a text channel, voice channel, or category in a server' and 'Returns the new channel', indicating it creates new resources that modify server structure.
