Ban a member from the server with options
AI agents call ban_member to permanently remove resources in Discord MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Banning a member is a severe, difficult-to-reverse moderation action that removes a user's access to the server and typically cannot be undone without deliberate manual intervention. This constitutes irreversible harm to the affected user's server membership.
