    About

    Atlantis API is a utility library for creating Forge server-side plugins and traditional mods. It includes AtlantisUI, a chest GUI API with pagination; AtlantisConfig, which manages files and databases while allowing data objects to work across storage types; and AtlantisData, which wraps Mojang API calls to retrieve player skulls, names, and UUIDs. For commands, AtlantisCommand and CommandBuilder provide alternative Brigadier wrappers, while Trident parses and reports on Forge mod and plugin update files. The library also provides TridentLevels, a multiverse solution and API for Forge, plus Pixelmon-specific type adapters and helpers, including AtlantisBattles, a simple battle executor and listener. Additional utilities include Atlantis Object Notation, a JSON variant with comments and simplified formatting, and convenience classes such as Text, ParsedItemStack, and LazyLevel.

    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 1.16.5 to 1.20.2.

    Changes the game's code in 1 area, as a library other mods build on: Networking and multiplayerChanges 1 game code file in this area: connections, the server list and what is sent between your game and a server..

    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 1.16.5 to 1.20.2.

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

    What it can do on your computer

    Uses folders outside the game
    It can read or write files outside your Minecraft folder, on the rest of your computer. Only in its files for Forge 1.20.2.
    Starts other programs
    It can start another program on your computer. It can read system or hardware information.
    Accepts connections from other computers
    It can accept connections from other computers.
    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 5 web addresses. 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 · Both 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.
      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.

    Privacy

    We found nothing it sends about you

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.16.5 to 1.20.2.

    We read its code without running it: it contacts 3 web addresses while you play.

    Like any connection, each address it contacts sees your IP address.

    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 · 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.

    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.
