create_text_channel · Discord MCP: Risk & Policy

WHAT IT DOES

What create_text_channel does on Discord

AI agents use create_text_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 create_text_channel needs a policy

Creating a text channel is a reversible write operation that modifies Discord server state. It is not destructive (the channel can be deleted), does not execute arbitrary code, and carries no financial impact. The blast radius is medium because unauthorized channel creation could clutter a server or be used to impersonate legitimate communication channels, but the impact is containable and reversible.

From the tool's definition Tool name is 'create_text_channel' and description states 'Create a new text channel'. This is a creation operation that modifies server structure by adding a new resource.
