Oper is a security plugin for Minecraft servers designed to control and manage operator (OP) permissions.

Key features:

Automatic OP Revocation — when a player leaves the server, their operator rights are automatically removed.

Custom OP and DEOP commands — instead of the standard /op, the plugin provides a customizable command (default op: /opme, default deop: /deopme).

Permission System — using the custom command requires the special permission oper.getop.

Standard Command Blocking — the default /op command can be disabled, ensuring players only use the custom command.

Auto-ban for Unauthorized Attempts — if a player without proper permissions tries to gain OP, they are automatically banned with a clear explanation.

Fully Customizable Messages — all plugin messages can be easily edited in the configuration file without recompiling.

config:

# Command that will grant OP rights to the player (without the /)
command: opme

# Permission required to use the command
permission: oper.getop
