About
Cores is a library mod for Minecraft mod development, packaging reusable code and offering features for both players and developers. Players can configure or disable fixes that adjust attributes’ default, minimum, and maximum values, and change experience-level deductions so they remove the exact experience required to reach the target level from level zero. Developers can customize the color palette used by the mod’s screens and some rendering code, and register paths for a local network listener that serves registered content on port 4444. The listener is disabled by default for security, restricted to localhost and read-only access to loaded resource files by default, and shuts down after inactivity unless configured otherwise.
Written from Modrinth and the GitHub README . How we write it
In-game changes
Changes the game's code in 4 areas, as a library other mods build on: Mobs and their behaviorChanges 4 game code files in this area: mobs, animals, villagers, projectiles and how they move and act., PlayerChanges 1 game code file in this area: your character: movement, abilities, hunger and controls., Server and world logicChanges 1 game code file in this area: the world, commands, scoreboards, saved data and game rules. and Rendering and graphicsChanges 1 game code file in this area: drawing mobs, items, particles and textures on screen..
Adds 1 key binding: Open Menu.
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
We checked its files and read their code, without running it.
What it can do on your computer
- Accepts connections from other computers
- It can accept connections from other computers. Only in its files for NeoForge 26.2 to 26.3.
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Found: your user folder.
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for NeoForge 1.20.1 to 1.21.1, 1.21.5 to 26.3; Forge 1.20.1 to 26.3. See Privacy
- Can download and run new code
- The same part of the code can download data and run it as code. Auto-updaters do this, and so does malware. Only in its files for NeoForge 1.21.5.Not a Warning: we read its code and found no code downloaded over http or run without a check.
- Starts other programs
- It can start another program on your computer, for example to open a link in your browser. Only in its files for NeoForge 1.21.5.
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
- 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.30 latest files: the newest file for each Minecraft version and loader. The answer above is about the 22 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.
- Accepts connections from other computersRuns a small web server.
- Starts other programsPurpose not known.
- Looked for, not foundWe looked for these in the file and did not find them.Updating itself, the webcam or microphone, an AI service.

We found nothing it sends about you
We read its code without running it: it contacts 1 web address 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
- 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 all 22 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.
- 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 description, files and images and found none.
We have not read its changelogs and code history 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.
How we checked
- 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.No AI content or AI features declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found in the descriptionChangelogs not read yet
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Nothing found
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found
- Code of the modThe code and files of the mod, read without running it: addresses of AI services, AI libraries, AI model files and a place for your own AI key.No AI service, AI library or AI model file250 code files read
