McQoy
Dependencyless* config screens! An in-game editor for Kaleido-based configs - with no setup required.
Quick answer
Which McQoy release should I use?
mcqoy-0.4.1+fabric-26.1.jar targets 26.1, 26.1.1, 26.1.2 with Fabric. The project page does not say whether this file belongs on the client, dedicated server, or both. All 8 required mods have matching files.
Where it goes
Is McQoy required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does mcqoy-0.4.1+fabric-26.1.jar need?
mcqoy-0.4.1+fabric-26.1.jar. Change the file and its required mods may change too.
Install YetAnotherConfigLib, Mod Menu, Mod Menu, YetAnotherConfigLib (YACL) and 4 more first. We found matching files for this game-version and loader setup. 4 come through another mod in the chain.
4 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does McQoy add?
QCONF OVER YACL (MCQOY)

He's dead, Jim.
Requires YACL.
McQoy is a simple mod that automatically generates YACL configuration screens for mods using Kaleido.
IT SEEMS I'VE MISSED YOU
Some mods use Kaleido to provide a .toml configuration - like our own Surveyor, or Crunchy Crunchy, or PicoHUD.
The files look nice, but you can't edit them in-game. With McQoy, you can! Just drop the mod in and you're set.
I DON'T NEED A DOCTOR, I AM A DOCTOR
To set this up for your own mod, check out Kaleido#usage - any loader and version, doesn't matter, it's universal.
When setting the config up, just make sure to specify your folder or filename as your mod ID, so McQoy can find it.
You may find this arrangement terribly pleasant.
Then, on any McQoy-compatible version, installing McQoy will add screens! No setup, and no hard dependency.
For player visibility, you can also set McQoy as an optional dependency on Modrinth/CF. (Or required, I'm not a cop.)
IF I'M NOT CAREFUL, I'LL END UP TALKING TO MYSELF
Oh, right - a little background and credit is due:
ALL I GOT LEFT IS MY BONES
Quilt Config isn't built on quilt, or even minecraft - It's a pure-java configuration library.
That means it works on every loader, and every version of minecraft, with no changes required.
The API is even designed for mods like McQoy to utilize - with fancy annotation-based metadata. Thanks qconf!
I'M NOT A MAGICIAN, SPOCK
Kaleido is just a wrapper for Quilt Config that shadows the library to avoid path conflicts with Quilt Loader.
With quilt seemingly being sunset, we'll be sure to follow the maintainers if they decide to fork it (hi ix!)
FASCINATING
All mods are built on the work of many others.
This project is based on Quilt Config - and exists only because it's a genuinely great pure-java config library.
Special thanks to ix0rai and cassiancc for providing helpful code snippets and having good ideas to begin with.
