    About

    Epic Core API is a developer-focused library for manipulating Minecraft entities through APIs and commands, built on CoreMod, Java Agent, and Mixin technologies, with an MCreator plugin for using its APIs in MCreator projects. Its entity tools can set and lock health or maximum health, prevent healing, apply damage, kill or revive entities, control invulnerability, teleport or lock their location, remove entities, and manage spawning bans and force-loaded chunks. Health changes can account for entities whose real health is stored outside the usual vanilla fields, using analysis and verification to find and update the relevant storage; some advanced methods are gated by configuration. The mod also supplies entity extensions, block and item extensions, Blender-model animation and skill controls, and dimension-wide fog, skybox, and combat-music overrides. Additional modules support cinematic BossShow cutscenes, player screen filters such as sketch, matrix, rain, snow, and cosmos, custom factions with configurable relations and leaders, and custom raids that can be started and managed in the world. Vanilla attribute limits are raised to Double.MAX_VALUE by default, with an option to disable that behavior in the configuration.

    Written from Modrinth . How we write it

    In-game changes

    Changes the game's code in 12 areas, as a library other mods build on: Mobs and their behaviorChanges 11 game code files in this area: mobs, animals, villagers, projectiles and how they move and act., Rendering and graphicsChanges 6 game code files in this area: drawing mobs, items, particles and textures on screen., PlayerChanges 4 game code files in this area: your character: movement, abilities, hunger and controls., Chunk loading and storageChanges 3 game code files in this area: how the game loads, tracks, saves and unloads chunks., World renderingChanges 3 game code files in this area: drawing the terrain, sky, clouds and weather., Networking and multiplayerChanges 3 game code files in this area: connections, the server list and what is sent between your game and a server., Server and world logicChanges 3 game code files in this area: the world, commands, scoreboards, saved data and game rules., User interfaceChanges 2 game code files in this area: menus, screens, tooltips, the chat window and the in-game overlay., Game coreChanges 2 game code files in this area: the main loop, lighting and other code the whole game uses., SoundChanges 1 game code file in this area: playing sounds, music and the sound engine., Inventory and itemsChanges 1 game code file in this area: items, chests and other containers, crafting and enchanting. and Blocks and fluidsChanges 1 game code file in this area: how blocks, fluids and redstone work..

    Adds 2 key bindings: BossShow: Pause recording and BossShow: Start/Resume recording.

    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. 6 files in your config folder.
    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
    Sends the text you write to Anthropic and OpenAI
    The code calls an AI service over the internet, for example to write text or make images. You provide your own key.

    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 17 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.
    • Sends the text you write to Anthropic and OpenAI
      api.openai.com api.anthropic.com
    • 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.
    • Modrinth and CurseForgeA release with a different file on Modrinth and on CurseForge, whose code is not the same. Each file is checked on its own. Nothing is blocked.
      Minecraft 1.20.1 · Forge · release 1.1.7-fix-fix · 7 Aug 2026: Modrinth epic-core-api-1.1.7-fix-fix.jar, CurseForge epic-core-api-1.1.7-fix-fix.jar. 3 classes changed, in net.eca.util: ForceLoadingManager$TrackedChunk, ForceLoadingManager, RaidManager.
      code differs in 1 release

    Privacy

    Sends unknown data

    Sent to an address built while the game runs.

    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.
      The code of both files, for recent Minecraft versions. See each file in Releases
    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.
      Purpose not known.
      Unknown data
    • 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

    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.

    Can use AI in the game

    Can send the text you write to Anthropic and OpenAI (you provide your own key).

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

    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.

      Can use AI in the game:
      • Can send the text you enter to Anthropic and OpenAI. The address is written in the code of the mod.
      • Can talk to AI services that work like OpenAI's. You or the author choose which one.
      • Implements Model Context Protocol server (tool access for AI assistants).
      • You provide your own API key.
