    About

    Multiblocked2 is a visual, code-free tool for designing custom machines and multiblock structures in Minecraft, with an editor for configuring machine designs. Its node graph lets creators respond to machine events and build execution logic without relying on KubeJS for complex functionality. Machines can use inputs and outputs such as items, fluids, Forge energy, entities, and supported mod resources including Create stress, Botania mana, Mekanism chemicals and heat, and PneumaticCraft pressure. Recipes can define processing time, per-tick consumption, output chances, and conditions such as dimension, biome, weather, or machine level. A demonstrated machine is a fire pedestal that burns coal to produce fire and illuminate its surroundings.

    Written from Modrinth and CurseForge . How we write it

    In-game changes

    Changes the game's code in 4 areas, as a library other mods build on: Chunk loading and storageChanges 2 game code files in this area: how the game loads, tracks, saves and unloads chunks., Inventory and itemsChanges 1 game code file in this area: items, chests and other containers, crafting and enchanting., Server and world logicChanges 1 game code file in this area: the world, commands, scoreboards, saved data and game rules. and Blocks and fluidsChanges 1 game code file in this area: how blocks, fluids and redstone work..

    A library packed inside it changes 1 more game code file: KilaGraph.

    Adds 1 item: MBD Gadgets; 1 recipe.

    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

    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 · 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. Both are 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.
      The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    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 · 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 recent Minecraft versions. See each file in Releases
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    An AI tool may have been used

    Claude Code is named in the ignore list of its repository.

    This does not show that it was used to make the files you download.

    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.

    How we checked · 6 places read
    • Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.
