Plugin ModSync

ModSync for Minecraft Server

ModSync is a Java Edition plugin and client mod designed to support fair play on a Minecraft server. It verifies installed mods and resource packs through a secure challenge response process, checks active and inactive packs, and blocks content listed as banned. The system can also link a player account to a unique device authorization key, helping prevent account sharing.

Server staff receive clear per player records with mod and pack history, removal timestamps, and readable dependency filtering. Optional screenshots and file diagnostics help investigate suspicious content, while consent prompts add transparency. At BoxToPlay, we see it as a practical tool for a more accountable server experience.
