Modlist Snooper
by lunofe
Modlist Snooper lets server operators see which mods connected clients have installed, a view Forge no longer shows by default.
What it does
Forge removed the verbose log line that recorded each player's mods when they joined, and operators who relied on it lost insight into what players run. Modlist Snooper restores that view by registering a command that reports the client mod list, so an operator can check a player's installed mods from the server.
The mod is a Forge management tool for servers that want to control which client mods can connect. It lists the mods each player uses in-game, and it can automatically ban players whose installed mods match a blacklist. Because the environment is client and server, the server and every player need the mod for the checks to run, and a player who removes the mod from a modpack cannot join the server.
Files target 1.20.1 only, and the latest Forge build is 1.1, published on 2024-03-06 after a first release on 2024-02-16. The code is released under All rights reserved, so the mod is not open source.
Key features
In-game mod list
Operators and players can view the list of mods a connected client is running, without reading server logs.
Automatic blacklist bans
Players whose installed mods match a configured blacklist can be banned automatically when they join.
Required client mods
The server can require clients to install the mod, so a player who removes it from a modpack is refused entry.
Replacement for removed logging
It replaces the join-time mod logging that Forge dropped, giving operators the same information through a command.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Server moderation
Server owners use the blacklist to keep out players who run mods known to disrupt gameplay or give unfair advantages.
Mod-auditing on multiplayer servers
Operators check which mods players use without asking them, which helps when troubleshooting joins or crashes.
Who it’s for: Server operators who run Forge on Minecraft 1.20.1 and want to see or limit the mods their players connect with.
How it compares
NoSnooper is a Forge mod for 1.8.9 and is client-side only, so it cannot give a server operator this view. Better ModList is open source under the MIT License and runs on Forge and NeoForge for 1.20 – 26.3, and only the client needs it. Mod Whitelist is open source under the MIT License, supports Fabric and Forge for 1.20 – 1.20.4, and works on either side, and neither needs it.
