Command Blocker Plus

The ultimate lightweight solution to secure your server's commands and privacy.

CommandBlockerPlus is a powerful, high-performance utility designed for Minecraft 1.21.1. It gives server administrators total control over which commands players can see and execute, ensuring that sensitive information like your plugin list or internal server setup remains hidden from unauthorized users.

Key Features

Total Command Blocking: Automatically blocks execution of any command not explicitly listed in the whitelist.

Intelligent Tab-Completion Filter: Using the PlayerCommandSendEvent, the plugin removes unauthorized commands from the player's suggestion list.

Filtered Suggestions: Players will only see the commands they are allowed to use in the tab-complete menu.

Immersive Feedback: When a player attempts to use a blocked command, they hear a Villager No sound for instant, clear feedback.

Clean Action Bar UI: Uses the Action Bar to keep the chat clean. The default message is styled with a sleek, small font: ᴛʜɪꜱ ᴄᴏᴍᴍᴀɴᴅ ᴅᴏᴇꜱ ɴᴏᴛ ᴇxɪꜱᴛ..

Admin Bypass: All restrictions are automatically bypassed for Server Operators (OPs), allowing you to manage your server without limitations.

Configuration

The plugin is easy to configure. You can define your whitelist and custom message in the config.yml:

# CommandBlockerPlus Configuration
blocked-message: "&cᴛʜɪꜱ ᴄᴏᴍᴍᴀɴᴅ ᴅᴏᴇꜱ ɴᴏᴛ ᴇxɪꜱᴛ."

# Commands that players WITHOUT op are allowed to use
allowed-commands:
  - tpa
  - tpaccept
  - tpdeny
  - pw
  - rtp
  - spawn

Installation
