move_channel · Discord MCP: Risk & Policy

WHAT IT DOES

What move_channel does on Discord

AI agents use move_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 move_channel needs a policy

Moving a channel is a write operation that changes channel organization state. It is reversible (a channel can be moved again or out of a category), so it does not qualify as Destructive. The impact is moderate—it affects channel visibility and organization but not message content or user access directly. Severity is medium because an agent could disorganize server structure, but the change is undoable.

From the tool's definition Tool description states 'Move a channel into a category' and 'organize channels under category groups.' This modifies channel metadata (parent category assignment) reversibly without deleting data.

Verdict

move_channel Rate-limited

move_channel stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
