Ultimateservercore

UltimateServerCore is an all-in-one Minecraft server core plugin built for Paper 1.21+. It combines essential commands, login security, skin management, and multiple protection systems into a single lightweight plugin.
The plugin includes Essentials commands like /spawn, /home, /warp, /tp, /heal, /feed, and /fly with permissions, cooldowns, and customizable messages. It also features a secure login system with /register and /login, blocking movement, chat, and commands until the player authenticates.
UltimateServerCore also provides a skin system that lets players change skins using Minecraft usernames, even on offline-mode servers. For server protection, it includes anti server advertising, anti hack detection (speed and fly), and anti bot protection to prevent join floods and bot attacks.
All modules and settings are fully configurable through config.yml, allowing server owners to enable, disable, and customize every feature easily.
