About
Whitelist Sync 2 keeps player access and moderation lists consistent across multiple Minecraft servers by sharing their data through a common MySQL or SQLite database, or the Whitelist Sync Web service. It detects changes made with normal Minecraft commands and propagates whitelist and operator updates to connected servers; banned-player and banned-IP lists are supported through the Web service. With self-hosted databases, the mod polls for changes, and server administrators can also manually pull or push synced lists.

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 is not checked yet.
What it can do on your computer
- Accepts connections from other computers
- It can accept connections from other computers.
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Found: the temporary files folder, your user folder and application data.
- 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 Fabric 1.20.1 to 26.3; NeoForge 1.21.1 to 26.3.
- 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 code libraries built into it. See Privacy
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file 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.63 latest files: the newest file for each Minecraft version and loader. The answer above is about the 44 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
- 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.
- Uses folders outside the gameUses the temporary files folder.Uses the system folder for application data.
- 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.
Privacy
Sends text to an AI service, your player ID and unknown data
Sent to an address built while the game runs.
Only some of its files send your player ID and unknown data.
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 44 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.Sends text to an AI service for a purpose not known. Checks for a new version of the mod.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.
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 found21 of 40 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 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 file3,000 code files read
