Disable /seed for clients
by Jackbot50
Disable /seed for clients is a server-side Fabric utility that lets operators switch off the /seed command for other players.
What it does
Operators can toggle whether ordinary players may run the /seed command. When the ability is disabled, players who type it are refused, and the mod exposes a boolean value that reports whether /seed is currently available. Changes made in game take effect in real time, so no world reload is needed.
The mod is only installed on the server. Players join without installing anything, and a server owner decides which players keep access to the command. Operators need permission level 2 or greater to change the setting, and the mod accepts the usual set of possible inputs for that permission.
Files are published for Fabric only, across nine release versions covering 1.21.7 – 26.3. The latest Fabric file, 1.0.2-26.3 for 26.3, was dated 2026-09-16. The project is released under All rights reserved and is not open source. Issues can be reported through its public issue tracker.

How it compares
Seed Checker is a client and server mod under the MIT License, published for 1.21.8 only, so it does not cover the same version range. Slime is server-side only and open source under the GNU Lesser General Public License v3.0 only, with files for 1.18.1 – 26.2. Survival Fabric is open source under CC0 1.0 Universal and can run on the client, the server or both, with files for 1.21.4 – 26.2. This mod differs from all three by being server-side only and not open source.
