Maykesh's Secure Server Mod
by pz.labs
Maykesh's Secure Server Mod is a server-side anti-cheat for Fabric that checks player movement, combat and world interaction for exploits, without requiring anything from players.
What it does
Servers that run the mod need nothing on the player side: vanilla clients join without installing any additional mod. Checks cover speed and timer abuse, flight in survival, walking through walls and floors, and spoofed ground states that would otherwise avoid fall damage. Detection uses heuristics aimed at exploits in movement and combat that other anti-cheats may leave unseen.
The mod also covers login handling, with protections around authentication timeouts and the short window granted when a player connects. Its checks are described as lightweight, so they are meant to run without slowing the server. Only the server needs it, and the mod is published for Fabric only, with 12 release versions 1.21 – 1.21.11 and the latest file for 1.21.1.
Maykesh's Secure Server Mod is released under All rights reserved and is not open source. It was first published on 2026-01-26 and last updated on 2026-03-05.
