PacketDump
A simple packet dumping mod for Minecraft.
PacketDump lets you choose exactly which packets you want to monitor, then dumps every instance of those packets while the dumper is active inside logs. It's useful for debugging, reverse engineering, learning how the protocol works, or just seeing what's happening between the client and server.
Features
- Select individual packet types from an easy to use GUI
- Dump only the packets you care about
- Logs packet data to the game log
- Hold F9 to dump packets only while the key is held
- Lightweight with minimal overhead when not in use Controls
Right Shift: Open the PacketDump menu
F9: Hold to activate packet dumping (default keybind)
Whether you're developing a mod, tracking down a networking issue, or just curious about Minecraft's packets, PacketDump makes it easy to inspect network traffic without digging through every packet the game sends.
No complicated setup. Open the menu with Right Shift, choose the packets you want to monitor, hold F9, and start logging.
