CommandGuard

A PaperMC plugin for PvP servers that prevents players from using commands immediately after joining. Players must physically move at least one block from their spawn position before any command will be accepted.

Why?

On public Minecraft servers, automated bots, malicious clients, and scripted connections can attempt to execute commands immediately after joining — before the player has fully loaded, spawned, or passed normal server checks. CommandGuard helps close this vulnerability window by ensuring commands are only available once a player has properly entered the world and shown normal player activity, such as being spawned and able to move.
