No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Uses your Minecraft account login
- It can use the login of your Minecraft account, for example to join a server. Only in its files for Fabric 26.1 to 26.3.Not a Warning: we read its code and found no login token sent anywhere but Mojang.
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Found: your Downloads.
- 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
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. 4 files in your config folder.
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.4 latest files: the newest file for each Minecraft version and loader. All 4 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
- Uses folders outside the gameUses Downloads.
- Looked for, not foundWe looked for these in the file and did not find them.Other programs, updating itself, the webcam or microphone, an AI service.
Privacy
Sends unknown data
Sent to api.minecraftservices.com, login.live.com, user.auth.xboxlive.com and xsts.auth.xboxlive.com.
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
- 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 4 files, for recent Minecraft versions. See each file in Releases
- api.minecraftservices.comTalks to the Minecraft login service.Unknown data
- gitlab.comPurpose not known.Nothing about you
- login.live.comTalks to the Minecraft login service.Unknown data
- user.auth.xboxlive.comTalks to the Minecraft login service.Unknown data
- xsts.auth.xboxlive.comTalks to the Minecraft login service.Unknown data
- Address built while the game runsThe code builds this address while the game runs: it is not written in the file.Checks for a new version of the mod.Nothing about you
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.
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.Not on Modrinth.
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found16 of 24 changelogs read
- 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 found1 image read
