Modclaimer Utils
Modclaimer Utils is a Forge utility for 1.20.1 that lets a server owner ban players from using chosen mods, with a simple config file.
What it does
The mod is configured to block specific actions for players: mining blocks, picking up items, wearing armor, and interacting with items or blocks. Server owners pick which of these a player is stopped from doing. A separate option enables a troll mode that instantly kills a player who attempts an interaction. Modclaimer Utils runs on client and server, so both the server and every player need it. Its Forge files cover 1.20.1, released as 1.0.0 on 2026-07-29 under All rights reserved; the code is not open source.
