Where it goes
Is Mson required on the client, server, or both?

This file is marked client-only.
What else does Mson 1.13.1+26.1 need?
1.13.1+26.1 on 26w14a. Every mod below is checked against that same setup.
Install Fabric API first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

What is Mson?
Wiki | Model Language Definition
Mson is a fabric library/mod for defining and loading entity models through configurable json files.
It makes modders' lives easier by taking the model geometry out of the code and putting it in a place where it's separated from game logic,
and it makes player's lives better by making it possible for your models to be customised and replaced using nothing more than a resourcepack.
Getting Started [ResourcePack & Mod Creators]
When MSON is installed, every entity model in the game can be loaded from an equivalent json file in the assets/<namespace>/models/entity/mson folder. Check this folder for a short list of example models made to closely (and in some cases not very closely) match the equivalent model for a limited few vanilla entities.
For a more complete list, and instructions on how to convert models already loaded into the game, check the Sample 1.20.1 Models wiki page.
Getting Started [Mod Creators]
Want to register your own models to load with mson? Doing so is as simple as:
assets/<modid>/models/entity/my_model.jsonstatic ModelKey<MyEntityModel<MyEntity> MY_ENTITY_MODEL = Mson.getInstance().registerModel(new Identifier("mymod", "my_model"), MyEntityModel::new);MyEntityModel<MyEntity> model = MyModels.MY_ENTITY_MODEL.createModel();
Want to create a humanoid model? Mson already bundles models for steve, alex, and a simplistic quadruped, so just specify { "parent": "mson:steve" } as your starting model and add override for each body part as you go. Check here for examples!
