    About

    Vicious Core is a utility and development library for Minecraft mod and modpack creators, aimed at reducing repetitive implementation work while keeping client-server behavior efficient. It provides synchronized keybindings whose pressed states are available to the server, allowing mods to handle player inputs on both sides of a multiplayer game. Its SyncableData system helps mods save and load data through NBT while controlling whether client-originated changes are permitted. For interface development, it includes a relative-positioning GUI system in which widgets are laid out relative to their parents, so components can move with a background rather than being fixed to screen coordinates. Annotation-driven automation can simplify registration of block entities, items, and containers, and can attach syncable values to data compounds. The library also includes a Holoinv GUI and functionality from ViciousLib.

    Written from CurseForge and the GitHub README . How we write it

    In-game changes

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2 to 1.19.2.

    Changes the game's code in 3 areas, as a library other mods build on: Mobs and their behaviorChanges 1 game code file in this area: mobs, animals, villagers, projectiles and how they move and act., Chunk loading and storageChanges 1 game code file in this area: how the game loads, tracks, saves and unloads chunks. and Blocks and fluidsChanges 1 game code file in this area: how blocks, fluids and redstone work..

    Adds 2 items: Area Selection Wand and Structure Paster Wand.

    Counted from the names and data files in the mod, so the list may not be complete.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2 to 1.19.2.

    We checked its files and read their code, without running it.

    What it can do on your computer

    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 2 files 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. No web address is written in its code. See Privacy
    Starts other programs
    It can start another program on your computer, for example to open a link in your browser. Only in its files for Forge 1.12.2.
    Can download and run new code
    The same part of the code can download data and run it as code. Auto-updaters do this, and so does malware. Only in its files for Forge 1.12.2.Not a Warning: we read its code and found no code downloaded over http or run without a check.

    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 · All 3 latest files checked, last on 16 Oct 2026
    • 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.
      3 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. 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
    • 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

    We found nothing it sends

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2 to 1.19.2.

    We read its code without running it: it contacts no web address while you play.

    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 · All 3 files read
    • 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 3 files, for Minecraft 1.12.2 to 1.19.2. See each file in Releases

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its description, files and images and found none.

    We have not read its changelogs and 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.
