WHAT IT DOES

What discord_ban_user does on Discord MCP Server

AI agents call discord_ban_user 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.

RISK

Why discord_ban_user is rated Critical

Banning a user from a guild is a destructive, high-impact moderation action. It removes the user's access to the entire guild and all its channels. While technically reversible via an unban, the ban itself is a one-way destructive action with significant social and operational impact. Misuse by an AI agent could result in mass bans, severely disrupting a community.

From the tool's definition 'Ban a user from a guild' — banning is an irreversible moderation action that removes a user's access and cannot be undone without an explicit unban action
