How to OP and Manage Admin Players on your Minecraft Server

Like most games, Minecraft provides a built-in mechanism to set authorized players as administrators of the server. Mojang, the game developer, has chosen the term OP (operator).

An operator is one of the highest levels of access any player can have on a Minecraft server.

Managing OP Players

You can assign OP players by using either the Nodecraft Pro panel, Console Commands, or even in-game commands (by other OPs).

Managing OP in the Nodecraft Pro Panel

Firstly, ensure you're on the control panel for your Minecraft server. Under the Players page, you will find an OPs tab. Any players added to this list will automatically be OP-ed by our system. After making changes to players, you may need to restart your server to apply the new settings.

Assigning OP via Console or In-Game Commands

Using the command /op you can assign or remove ops.

/op <playername> - to add a player as OP status

/deop <playername> - to remove a player from OP status
When using the web-based console, be sure to drop the / from the start of the command

Permission Levels

Since the 1.7.10 snapshot release (13w19a), Operator Permission Levels were introduced into Minecraft, to give server administrators much more granular control over operator permissions. Each permission level is assigned various commands and inherit all commands from the previous level. For example, a level 3 operator also has access to the commands from both level 2, and level 1. The highest possible operator permission level is 4.
