Plugin ProtocolLib

ProtocolLib, the packet toolkit for Minecraft servers

ProtocolLib is a Bukkit, Spigot and Paper library that lets plugins intercept, read and modify the network packets exchanged between client and Minecraft server. By exposing the protocol layer through a clean API, it removes the need to touch fragile NMS code, making advanced features easier to maintain across many Minecraft versions.

Developers use ProtocolLib to build custom visuals, anti cheat checks, fake entities, virtual blocks or GUI interactions that depend on packet manipulation. On BoxToPlay, we rely on it to help creators push serveur Minecraft gameplay further while keeping performance and compatibility under control.
