    Security

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.8 to 1.19.3.

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

    What it can do on your server

    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Found in code libraries built into it. See Privacy

    Why we show this: a plugin runs on your server like any program, so harmful code in it can take over the server. 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 · Both latest files checked, last on 20 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.
      2 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, 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 1.8 to 1.19.3.

    We read its code without running it: it contacts no web address while the server runs.

    Why we show this: a plugin can send things about your server and its players over the internet, like their player name or their login. Contacting an address to check for updates or download files sends nothing about them. Not in the grade: sending data can be normal for what a plugin does.

    How we checked · Both 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 both files, for Minecraft 1.8 to 1.19.3. See each file in Releases

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its texts, files and images 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.
