McCore
McCore is a Fabric library mod that serves as the engine for a suite of RPG modules, managing player data and skill leveling for McGather and other add-ons.
What it does
McCore handles the heavy lifting shared by the suite: it tracks each player's data and applies skill leveling curves. The author describes it as the foundation of a growing ecosystem aimed at a layered, progression-driven adventure on Fabric. Fabric API must be installed alongside it. Its first module, McGather, is available and adds skill progression through woodcutting, mining, excavating, fishing, herbalism and smelting.
The McCombat module is listed as in progress and is described as a combat overhaul built around weapon proficiencies and specialized combat abilities. McMisc is marked as planned. McCore adds gameplay features of its own, including level progression and XP gain, tree felling, instant mining and digging, mob hooking, sneaky growth and fuel efficiency, along with in-game top player lists. Installing a module such as McGather starts the leveling process.
Files are published for Fabric only, covering 1.21.9 and 1.21.10, with McCore_1 for 1.21.10 as the latest build, released on 2026-03-04 on the beta channel. The mod first appeared on 2026-03-03.
