SimpLimeDefender

SimpLimeDefender is a lightweight server-side security plugin for Minecraft (Paper 1.16.5).
Its purpose is to help protect servers from a common type of griefing attack where malicious users try to log in with the same name as an operator (admin).

? What it does

Monitors player logins:
If someone tries to join the server using the name of an operator who is already online, the plugin will block the login attempt. Optionally, it can even shut down the server to prevent exploitation.

Detects suspicious operator behavior:
If an operator account starts spamming dangerous commands such as /fill, /team, /scoreboard, etc., the plugin automatically bans that account permanently with a configurable ban reason.

Customizable configuration:
The file ConfigLimeDef.yml is generated inside the plugins/ folder, where you can adjust:

Which commands should trigger automatic bans

Whether the server should shut down on operator name conflicts

The messages and ban reason shown to players

Admin notifications

✅ Why use it

Running a free or public Minecraft server to play with friends often means being exposed to bot attacks, port scans, and impersonation attempts.
SimpLimeDefender adds an extra layer of protection to keep your operators and console safe from malicious intruders, without requiring external firewalls or complicated setups.

ℹ️ Additional information

Works only on the server side. Players do not need to install anything.

Compatible with Paper 1.16.5 and related server platforms.

Configuration is reloadable in-game with /simplimedefender reload.
