Automatic Operator
by Serilum
With Automatic Operator installed on a dedicated server, specific players receive operator status each time they log in.
What it does
Automatic Operator grants operator status to chosen players when they join a server, so a server owner does not have to run a command by hand after each login. The feature is off by default and is switched on in the config file, where the server owner sets enableAutomaticOperator to true. The mod was built for modpacks, where the setting is turned off unless the pack author enables it, which keeps the behavior from appearing where nobody asked for it.
By default the mod only runs on dedicated servers and ignores single-player worlds and integrated servers. Which players are affected is controlled by two options: when onlyMakeSpecificPlayerNamesOP is false, every player who logs in becomes an operator, and when it is true, only the names listed in specificOperatorPlayerNames do. That list is comma-separated and defaults to Player1,Player2, so the names have to be edited before use.
Automatic Operator requires Collective. It runs on the server alone, so players join without installing anything, and a single build covers Fabric, Forge, NeoForge and Quilt. Files are published for 26 release versions, 1.18.2 – 26.3, with 26.3.0-1.6-fabric+forge+neo as the latest file for 26.3, released under All rights reserved and not open source.
Key features
Login-based operator grant
Each time a listed player logs in, the server makes that player an operator automatically.
Off by default
The config option enableAutomaticOperator defaults to false, so the behavior must be turned on deliberately.
Dedicated servers only
The onlyRunOnDedicatedServers option defaults to true, which keeps the mod from running in single-player and LAN sessions.
Name-based targeting
With onlyMakeSpecificPlayerNamesOP enabled, only the names in a comma-separated list receive operator status.

How it compares
Operators Only! Continued is a Fabric-only, server-side mod for 1.21.11 – 26.2 that is open source under the MIT License. LAN Operators is a client-side mod for 1.16 – 1.21.4, also MIT licensed and open source, so it changes the local session rather than a dedicated server. Automatic Operator differs from both by applying on dedicated servers across Fabric, Forge, NeoForge and Quilt, with a login trigger instead of a LAN or manual approach.

What the author says
Automatic Operator was initially created to make testing server-side mods easier in Fabric. By default, Fabric chooses a random name (Player1 -> Player999) as the username. This caused some issues in the development server where I needed cheat-access for testing. This mod makes it so that any player that joins, is…
