    About

    FC: Library is a shared support library for many FictionCraft team mods, with JSON configuration features that mod and pack developers can use to represent Minecraft objects and pass data to compatible mods. Its object providers describe items, blocks, entities and fluids using registry names or tags, with fields such as item amounts, NBT data and block-entity state where applicable. Argument providers build on those object descriptions to express effects or conditions; for example, an item-giving argument can specify the item, chance, and whether it drops on the ground or goes into a player's inventory. The library also includes commands to reload its configuration files, inspect available arguments, and generate object-provider data for a held item or targeted block or entity.

    Written from CurseForge . How we write it

    In-game changes

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.16.3 to 1.16.5.

    Changes the game's code in 1 area, as a library other mods build on: Game data and resourcesChanges 1 game code file in this area: recipes, tags, advancements, language files and other game data..

    Adds no new blocks, items or other content.

    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 1.16.3 to 1.16.5.

    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.

    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 · The latest file 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.
      1 latest file. It is not for a recent Minecraft version, so the answer above is about it. 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.
      The internet, folders outside the game, other programs, 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 1.16.3 to 1.16.5.

    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 · Its one file 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 its one file, for Minecraft 1.16.3 to 1.16.5. 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.
