    About

    Oxygen Core is the shared API and foundation for the Oxygen mod series, which adds graphical-interface-based tools for multiplayer servers and clients, including social features, activities, and economy systems. Core itself provides player activity statuses, notifications and requests, virtual currency, client settings, and a privilege system for managing permissions. Players can set their status to online, away, do not disturb, or offline; those marked offline are hidden from lists and do not receive requests, while friends and group members can see their last activity by hovering over the status. The notification menu collects incoming requests and important messages, including confirmations for actions such as friend requests or votes, and operators can send system notices to individual players or everyone online. The built-in economy supports coins, shards, and vouchers, with coins serving as the base currency, and currency providers can connect or replace currencies from other mods. Its role-based privilege system lets operators assign players roles with specific permissions and chat formatting, while players can view their roles and choose active chat formatting through graphical menus. Oxygen Core is required by the other Oxygen modules, which include Daily Rewards, Exchange, Friends List, Groups, Mail, Merchants, Players List, Shop, Store, Teleportation, and Trade.

    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 1.12.2.

    Adds 7 sounds: Button Click, Context Close, Context Open, Drop Down List Open, Inventory Operation, Request Recieved and Ringing Coins.

    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.

    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. It contacts 1 web address. 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 · The latest file checked, last on 15 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.
      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 1.12.2.

    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 · 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 1.12.2. See each file in Releases

    AI

    No sign that AI was used to make it

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