Command blocker.

The mod includes several in-game commands for managing the list:

• /commandblocker add <command> - block a command on the current server
• /commandblocker remove <command> - unblock a command
• /commandblocker list - show the blocked commands for the current server
• /commandblocker listall - show every configured server and its blocked commands
• /commandblocker clear - remove all blocked commands for the current server
• /commandblocker enable - enable command blocking for the current server
• /commandblocker disable - disable command blocking while keeping the list saved

You can also block the wildcard * to prevent all commands on a specific server, while the mod’s own /commandblocker commands remain protected so you can always manage the configuration. Settings are saved per server and persist between launches.

This is a purely client-side mod: it only affects what your own Minecraft client is allowed to send. It does not change server rules, does not affect other players, and cannot be used to enforce restrictions on a server unless everyone has the mod installed. It is ideal for players who want to reduce impulsive command use, avoid risky actions, or simply create personal command guardrails for specific servers.
