Plugin ProtocolLib

ProtocolLib for advanced packet control

ProtocolLib is a powerful Bukkit and Paper plugin that gives developers read and write access to the Minecraft protocol, intercepting packets between client and Minecraft server. Instead of dealing with obfuscated internal code, it offers a clean event based API to monitor, modify, or cancel incoming and outgoing packets, from chat and entities to custom visuals.

Many plugins use ProtocolLib as a foundation for features like anti cheat checks, fake entities, or holograms while staying compatible across numerous Minecraft versions. On BoxToPlay, we recommend it when you need deep control over gameplay on a performant Minecraft server or serveur Minecraft.
