No harmful code found in the parts we could check
We checked its files and read their code, without running it.
One of its files for recent versions cannot be checked: its author does not let other sites download it from CurseForge.
The author declares on Modrinth that this mod interacts with your system outside the game.
What it can do on your computer
- Can update itself
- It can add or replace files in your mods folder, for example to update itself.
- Accepts connections from other computers
- It can accept connections from other computers. Found in the mod's own code and in okhttp, a library it includes.
- Starts other programs
- It can start another program on your computer. It can run a script interpreter, run a media tool, open a web link or a file, open a folder in the file manager and shut down or restart the computer.
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Found: your Downloads, your user folder, the temporary files folder, launcher files and application data.
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. 24 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. Found in the mod's own code and in 4 libraries it includes. See Privacy
- Talks to an AI service that you or the author set up
- The code calls an AI service over the internet, for example to write text or make images. It uses an AI service.
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.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. 1 of them is not checked yet. 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
- Accepts connections from other computersRuns a small web server.
- Uses folders outside the gameUses Downloads.Reads launcher files.Finds the Minecraft folder.Uses the system folder for application data.Uses the temporary files folder.
- Looked for, not foundWe looked for these in the file and did not find them.The webcam or microphone.
Privacy
Sends what you type in its screens
Sent to api.curseforge.com and api.modrinth.com.
We found this in its code, read without running it.
We have read the code of 1 of its 2 files for recent versions.
The author declares on Modrinth that it shows advertisements.
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.

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 talk to an AI service that you or the author set up.
We found this in its code, read without running it.
The author also declares AI features on Modrinth.
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
