ModListReporter
by RedBounce_
ModListReporter lets a Fabric client send its installed mod list and resource packs to the server each time a player connects.
What it does
When a player joins a server, the client sends a list of its installed mods and active resource packs to that server automatically. A server owner can use this to see which mods players run, which helps when troubleshooting joins or checking for unexpected client-side content. The data arrives at connection time without any action from the player.
On the server side, a Paper plugin named ModListReceiver collects the incoming data, logs it, and writes each report to a plain text file organized by the player's name and connection. Fabric API is needed for the client mod to run on Minecraft 1.20.2, and the same files can be read later for analysis. Only the 1.20.2 version is published, under the Apache License 2.0, and the code is not open source.
The mod works on either side, and neither side needs it. The server reads the reports only when the Paper plugin is installed, so a client without the plugin still works normally.

Use cases
Checking player setups on a server
A server owner can compare the mods and packs players report against the server's expected setup.
Investigating join problems
Saved reports give a record of what a player was running when a connection failed or behaved oddly.
Who it’s for: Server owners running Paper 1.20.2 who want to track the client-side mods and resource packs of players joining their server.
