Operators Only! (Discontinued)
by nadiral
Operators Only! is a Fabric server tool that limits who can join a server to players with operator status, and a command switches that mode on and off.
What it does
When the mode is active, the server admits only players who hold operator rank, so an admin can close the server to everyone else for testing or maintenance. Anyone who is not an operator and tries to join is shown a clear message explaining that the server is in Operators Only mode. The mode is turned on and off with a command, so no restart or file edit is needed.
The mod works like a second whitelist, except that the check is based on operator status rather than a separate list of names. It is a simple, lightweight access control layer, and it runs only on the server, so players join without installing anything. It requires Fabric API. The mod is published for Fabric only, across nine game versions 1.21 – 1.21.8, and the MIT License covers the code, which is not open source under a separate project page. The author has discontinued it and points to the Operators Only Continued fork by ArtixBTW as the successor.
Key features
Operator-only access
Only players with operator status can join the server while the mode is enabled.
Command toggle
A command turns the Operators Only mode on or off without restarting the server.

Use cases
Maintenance windows
An admin can close a server to ordinary players while carrying out repairs or updates.
Testing
Staff can test a server with only operators online before opening it to the general player base.
Who it’s for: Server owners and administrators who need to restrict a server temporarily to operators. Players install nothing, since the mod runs on the server only.
How it compares
Player Teleport is a server-required mod under the MIT License and is open source, with files for 1.21 – 1.21.11. LAN Whitelist runs on both client and server, is open source under the MIT License and covers 1.20.2 – 1.21.10, so every player needs it as well. Operators Only! is server-side only and does not cover a teleport or whitelist function.
