Ban a player from the Minecraft server.
AI agents call ban_player to permanently remove resources in OPanel MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Banning a player is effectively a destructive action: it permanently (until manually reversed by an admin) blocks a player's access. While technically a server admin could unban, the action is severe in impact and not easily or automatically reversible by the agent. Given the context of Minecraft server management, misuse could wrongfully ban innocent players, causing significant harm.
From the tool's definition "Ban a player from the Minecraft server" — banning a player is an irreversible access revocation action that removes the player's ability to connect to the server.
Attacks that exploit this kind of access
