NoMissingMods
This mod solves a common problem — it allows you to ignore the "Mod rejections" warning when connecting to a server, even if you don't have all the required mods installed.
How does it work?
When you try to connect to a modded server without all the required client mods, the game blocks entry and shows a compatibility error. NoMissingMods tricks the system by telling the server that you have all the necessary mods installed, allowing you to join the game world without problems.

Important limitations of current version
Attention! Currently, only the "Mini" version of the mod is available, which works with specific types of mods:
- ❌ Does not work with mods that add items or blocks
- ⚠️ May not work with mods that add mobs or dimensions
- ✅ Works excellently with generation mods for vanilla content (for example, village improvements or tree size changes)
A more functional version is under development — stay tuned for updates!
Setup and usage of MiniNoMissingMods
Manual method (client only)
First create a configuration file listing the mods that don't need to be installed on the client:
- In the client configuration folder (.minecraft\config) create the MNMM directory
- Inside, create the modlist.json file
- Add mods in the format:
{"modid":"version","modid":"version"}
Mod IDs and versions can be taken from the "Mod rejections" warning.
Example of modlist.json file structure:
{
"notenoughresources": "1.0.0",
"neiaddons": "2.3.0",
"wailaplugins": "1.2.1"
}
Automatic method (for client and server)
- Start the server with MiniNoMissingMods installed
- Execute the
/MNMM modlistcommand in the server console - Transfer the generated MNMM folder with modlist.json file from the server root directory to the client configuration folder (.minecraft\config)
- Remove MiniNoMissingMods from the server (optional — remove the MNMM folder from the server)
Note: the automatically created modlist.json file will contain all server mods. It's recommended to keep only those entries that are mentioned in the missing mods warning.
