    About

    MonkeyLib538 is a shared library required by OffsetMonkey538’s mods to run. It provides abstractions that help those mods support multiple mod loaders and Minecraft versions, and it handles platform differences in Placeholder API integrations, including text styling.

    Written from Modrinth . How we write it

    In-game changes

    Changes the game's code in 1 area, as a library other mods build on: Game coreChanges 1 game code file in this area: the main loop, lighting and other code the whole game uses..

    Adds no new blocks, items or other content.

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

    Security

    No harmful code found

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

    What it can do on your computer

    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Fabric 1.21.1 to 26.3; NeoForge 1.21.1 to 26.3; Paper 1.21.1 to 26.3. See Privacy

    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 22 latest files checked, last on 19 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.
      22 latest files: the newest file for each Minecraft version and loader. The answer above is about the 16 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, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    Sends unknown data

    Sent to an address built while the game runs.

    Only some of its files send unknown data.

    We found this in its code, read without running it.

    Its files for older Minecraft versions (1.21) also send usage statistics.

    The author declares on Modrinth that it sends crash reports or usage data unless you turn this off.

    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 16 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 16 files, for recent Minecraft versions. See each file in Releases
    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.
      Purpose not known.
      Unknown data
    • Named in its filesA crash report or usage data service named in the files of the mod. The code does not show when or what is sent.
      The code names Host name contains "telemetry" or "analytics", a service that receives usage data.

    AI

    No sign that AI was used to make it

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

    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.
