NexusCore Mod (NCM)
by MWT Studios
NexusCore Mod (NCM) is a server administration framework for Minecraft Java Edition 1.21.1, covering permissions, moderation, teleportation and player tools from a single install.
What it does
Server owners install NexusCore on a dedicated server, where it provides permissions, moderation, teleportation and player tools as one system. Players join with an unmodified vanilla client, so the admin panel renders as ordinary chest menus and full-screen ban screens. Fabric API is required, and the server must run the mod for it to take effect.
The framework keeps a tamper-evident audit log, with a record of administrative actions that the mod writes and checks. Its config and player files are read and written with safeguards, and death messages on Fabric keep their cause. Banned players see a styled screen that shows the remaining time.
The mod is published for NeoForge, Forge and Fabric from one codebase, and each release is verified on all three loaders before it ships. The latest 1.1.0 files are dated 2026-07-27, and the project has 214 automated tests with no failures. Only the server needs the mod, so clients may leave it out.
