NeoForge and MinecraftForge sync the entire content of all "server configs" to the client. Since this is not clear from the naming, some mods ended up putting secret values in these configs, e.g. Discord bot tokens. If you run a server using a mod with this issue, this allows any user that can join your server to access these values. This mod avoids this by removing sensitive values before the config is sent to the client.
Versions
Since this mod covers a wide range of Minecraft versions and two modloaders, the versioning scheme is somewhat complicated. See the table below for the correct version for your loader and Minecraft version.
| Loader | Minecraft version | Mod version suffix |
|---|---|---|
| MinecraftForge | 1.13.2 - 1.16.5 | -1.13.2 |
| MinecraftForge | 1.17.x - 1.20.1 | -1.17.1 |
| NeoForge | 1.20.1 | -1.17.1 |
| MinecraftForge | 1.20.2+ | -1.20.2-mcf |
| NeoForge | 1.20.2 - 1.20.5 | -1.20.2-neo |
| NeoForge | 1.21.0+ | -1.21.0-neo |
How it works
This mod works in two stages: First, it detects config options that potentially contain sensitive information during
launch. Since this is done using a very rough heuristic, the options that are found have to be manually classified in
the config/serverconfigcleaner-common.toml config file:
- Most of them will be false positives, harmless options that happen to match the heuristic. For example, the option
logistics.seatHostileMobsin Create would be marked as a potentially sensitive option since it contains the stringHost. These config values have to be added to thefalsePositiveslist. - Some of them may be options that contain actual sensitive values. These options have to be added to the
doNotSynclist in the same format, e.g.doNotSync = ["mymod:discord.token"].
To continue the launch, all found values have to be classified in the ServerConfigCleaner config. The mod ships with a list of known false positives and known "problematic" options (the latter not in plaintext). Therefore, you should usually not have to do anything at this stage. If you have to add values manually, see below on getting them added to the default lists.
In the second stage, the mod intercepts the config sync on the server. If a value was marked as sensitive in the config
after the first stage, the value will be replaced by the default value before being synced to the client. Since the
default value for sensitive options is generally a meaningless constant value provided by the developer (e.g. INSERT BOT TOKEN HERE), this can be sent to the client without revealing any secret information.
Reporting missed values
If you run into false positives that are not in the default list in the config, please create an issue listing them.
If you find any server config options that contain sensitive information and are not part of the default set of
sensitive options, please do not create an issue with these options. Instead, please get in touch with either

Installation Guide
Getting ServerConfigCleaner up and running on your Minecraft client is a straightforward process, but it requires careful attention to detail to avoid compatibility issues. Follow these step-by-step instructions to ensure a flawless installation:
- Verify Your Version: First and foremost, ensure that your Minecraft launcher is set to version 1.21.4, as this is the primary supported version for the current release.
- Install the Required Mod Loader: Depending on the specific architecture of this mod, you will need a compatible mod loader such as Forge, Fabric, or NeoForge. Download the installer from their official website and run it.
- Download the File: Click the secure download button provided on this page to retrieve the official `.jar` or `.zip` file for ServerConfigCleaner. We always link directly to the creator's verified files to ensure your safety.
- Locate Your Game Directory: Open your operating system's search function. On Windows, type `%appdata%/.minecraft`. On Mac, navigate to `~/Library/Application Support/minecraft`.
- Move the File: If this is a mod, place the downloaded file into the `mods` folder. If it is a shader, place it in `shaderpacks`. For textures, place it in `resourcepacks`.
- Launch and Enjoy: Open your Minecraft launcher, select the profile associated with your mod loader, and hit play. Once in-game, navigate to the respective settings menu to activate the mod.
Compatibility
One of the strongest selling points of ServerConfigCleaner is its robust compatibility profile. The developer, malte0811, has worked tirelessly to ensure that this project plays nicely with the broader Minecraft ecosystem. It is explicitly designed for version 1.21.4, meaning it takes full advantage of the latest engine optimizations and feature additions introduced by Mojang.
Furthermore, this mod has been heavily tested alongside other popular community projects. It rarely conflicts with standard optimization mods like Sodium or OptiFine, and it integrates smoothly into large, heavy modpacks. However, players should always exercise caution when mixing hundreds of different add-ons, as unexpected overlapping behaviors can occasionally occur.
Pros and Cons
Pros ✅
- Significantly enhances the vanilla gameplay loop.
- Highly optimized for version 1.21.4.
- Actively maintained and updated by malte0811.
- Excellent compatibility with major modpacks.
- Completely free to use and community-supported.
Cons ❌
- May require a decently powerful CPU/GPU for maximum settings.

Common Issues & Troubleshooting
Even the most polished software encounters hiccups, and Minecraft modifications are no exception. If you run into trouble while using ServerConfigCleaner, do not panic. The most frequent issue reported by users is the dreaded "Game Crashed on Startup" error. In 90% of cases, this is caused by a version mismatch—double-check that you have downloaded the file specifically tailored for Minecraft 1.21.4.
Another common scenario involves missing dependencies. Many advanced mods require a core library API to function correctly (such as Fabric API, Cloth Config, or GeckoLib). Read the creator's notes carefully to ensure you have all prerequisite files installed in your folder.
Performance Impact
Performance is often the primary concern for players when modifying their game. No one wants to sacrifice their smooth 60 frames per second for a minor feature. Fortunately, ServerConfigCleaner is incredibly well-optimized. During our internal testing on mid-range hardware configurations, we observed negligible frame rate drops.
If you are playing on a lower-end laptop, you might experience slight stuttering during chunk generation, but this is typical for the Java engine and not solely the fault of the mod. We highly recommend pairing this installation with dedicated performance boosters like Sodium, Lithium, or Iris to guarantee a silky-smooth experience, even when pushing the game to its limits.
Frequently Asked Questions (FAQ)
Is ServerConfigCleaner safe to download?
