MinepyLoader

by FFANXXY

MinepyLoader lets Fabric players and server owners run Python-style scripts inside Minecraft Java Edition 1.20.1, through a .mpy interpreter.

FabricClient and serverGNU Lesser General Public License v3.0 or laterOpen source1.20.1

What it does

Scripts with the .mpy extension are read and executed by an interpreter built into the mod. Scripts can define variables, parse method definitions, reference methods, and issue commands. Object-oriented programming is listed among the supported features, so classes and objects can be used in scripts. The mod is described by its author as an internal beta, and its latest build is ALPHA-0.0.3, last updated 2025-08-24.

The mod is marked as client and server, so a server that runs scripts and the players who connect need the mod installed. It requires Fabric API and is released under the GNU Lesser General Public License v3.0 or later, which makes it open source. Source code, an issue tracker and a wiki are linked from the project. Files are published for 1.20.1 only. The author notes that some parts are semi-completed, with more content scheduled for the next version, and that a game interface integration was demonstrated in ALPHA-half-0.0.3.

Key features

  1. Interpreter for .mpy scripts

    Scripts saved with the .mpy extension are loaded and run by the interpreter included in the mod.

  2. Variable definitions

    Scripts can define variables, a capability the author lists as present since ALPHA-0.0.2.

  3. Method parsing and referencing

    Scripts can parse method definitions and call methods by reference, listed as supported since the beta stage.

  4. Object-oriented programming

    The author lists object-oriented programming among the mod's features, for structuring script code into classes and objects.

Use cases

Scripted server behavior

A server owner can write .mpy scripts to automate in-game actions that would otherwise need manual commands.

Experimenting with a scripting language

Players interested in scripting can run small programs in the game to test variables, methods and classes.

Who it’s for: The mod suits server owners and players who want to write scripts that run inside Minecraft 1.20.1. Because several features are still semi-completed, it fits users who accept an alpha build with partial functionality.
