About
CatSkinC is a client-side Minecraft skin manager that lets players upload custom skins to its cloud and use them on multiplayer servers without requiring server-side installation. Players can drag and drop PNG skins in game, keep a reusable local library with thumbnails and quick selection, and preview each skin on a rotatable 3D player model before uploading, with Slim and Wide model choices. Players running CatSkinC see skin changes sync live, while players without the mod continue to see the player's normal vanilla skin. Optional mouth-open and mouth-close image overlays animate the skin's mouth during voice chat, with Simple Voice Chat and Plasmo Voice providing voice activity and Figura taking priority when an avatar is active. Skin uploads require a premium Mojang account, and the mod supports high-resolution skins up to 8192 pixels.

No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Uses your Minecraft account login
- It can use the login of your Minecraft account, for example to join a server. It can read the login token of your Minecraft account.Not a Warning: we read its code and found no login token sent anywhere but Mojang.
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file in your config folder.
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. It contacts 3 web addresses. See Privacy
- Starts other programs
- It can start another program on your computer. Only in its files for Fabric 1.20.1 to 1.21.1; NeoForge 1.21.1; Forge 1.20.1.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.7 latest files: the newest file for each Minecraft version and loader. All 7 are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Looked for, not foundWe looked for these in the file and did not find them.Folders outside the game, updating itself, the webcam or microphone, an AI service.
Privacy
Sends your player name, and uses your Minecraft login
Sent to an address built while the game runs.
We found this in its code, read without running it.
The author declares on Modrinth that it shows advertisements.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of all 7 files, for recent Minecraft versions. See each file in Releases

AI
AI was used for its code and text
The author declares AI code and text on Modrinth.
We looked for AI tools in its texts, files, images and sounds and found none.
We have not read its code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.Declares AI code, text. No AI features declared.
