Frequently asked
Does ProtocolLib work on Minecraft 1.21?
Yes. 1.21 is the newest Minecraft version ProtocolLib declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.
Which Minecraft versions does ProtocolLib support?
Everything the author has declared, from 1.8 up to 1.21. The full list is in the table above, with the Java runtime each version needs next to it.
Do I need to install ProtocolLib on the client or the server?
The server only. Players join with an ordinary Minecraft client and install nothing.
Which server software does ProtocolLib need?
Spigot. A build for one server platform will not load on another, so this is the first thing to check before the Minecraft version.
Which Java version do I need for ProtocolLib?
Java 21 or newer, because that is what the newest Minecraft release it supports requires. The requirement comes from the game rather than from the plugin itself.
How do I install ProtocolLib?
Download the file from the author's own release, drop it into your server's plugins folder, and restart the server. It generates its configuration on first start. Check the Minecraft version matches the one your server runs.
Where do I download ProtocolLib safely?
From the author's own page on SpigotMC, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.
