    About

    Programmable Command Blocks adds a compact block for putting large command-block creations into a single block. Its interface lets users create and delete commands, link a command to another command it depends on, and upload or download PCB creations through Pastebin or local files. Using the block requires creative mode and server-admin permission level 4 or higher. The mod also adds utility commands: /calculate evaluates mathematical expressions, /cutstr extracts text by character positions, and /getpos reports an entity's coordinates. Its /ifoffline command can be used in vanilla command blocks to output a comparator signal of 1 in an unshared single-player world and 0 otherwise.

    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 1.11.2 to 1.12.2.

    Adds 4 blocks: PCB, Programmable Command Block, SCB and Scriptable Command Block.

    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.

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.11.2 to 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. No address written in the code is contacted by the code that runs. 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.

    Sends crash reports

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.11.2 to 1.12.2.

    Sent to pastebin.com.

    Only some of its files send crash reports.

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

    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 so far that AI was used to make it

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

    We have not read its changelogs 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.
