McQoy
With McQoy installed, configuration files written for Kaleido can be edited in-game through generated YACL or Cloth screens, with no extra setup.
What it does
McQoy generates configuration screens automatically for mods that store their settings in Kaleido-based .toml files. Some mods built on Kaleido include Surveyor and Crunchy Crunchy. Their files are readable, but normally they cannot be changed in the game. When McQoy is present, the same settings appear as editable screens. A config is picked up when its folder or filename matches the mod ID of the owning mod, which is the only setup the config owner needs to check.
The mod depends on Mod Menu and YetAnotherConfigLib (YACL), and it uses Cloth where that library is the available option. Installation is a drop-in step: adding McQoy on a compatible version is enough for screens to appear. The mod is client-side only, so servers do not need it, and no hard dependency is imposed on the mods that it configures. McQoy is published for Fabric, Forge and NeoForge, with files for 26.1.2 on Fabric, 1.20.1 on Forge and 1.21.11 on NeoForge. Its license is custom and the project is not open source, though its source code and issue tracker are public.
Key features
Generated config screens
Settings from Kaleido-based .toml files are turned into editable screens without manual work.
Folder and filename matching
A config is detected when its folder or filename matches the mod ID of the owning mod.
Drop-in installation
Once the mod is added, the screens appear for any compatible Kaleido config found on the client.
Quilt Config foundation
Settings are read through annotation-based metadata from Quilt Config, a library that does not depend on Quilt or Minecraft.

Use cases
Editing Surveyor settings in-game
Players who want to change Surveyor's options can do so from a screen instead of opening the .toml file by hand.
Who it’s for: Players who use mods configured through Kaleido and want to change those settings inside the game, rather than editing text files.

What the author says
McQoy is a simple mod that automatically generates YACL (or Cloth) configuration screens for mods using Kaleido. Some mods use Kaleido to provide a.toml configuration - like our own Surveyor, or Crunchy Crunchy, or PicoHUD.
