Frequently asked

Does Minecraft Server API work on Minecraft 1.21.8?

Yes. 1.21.8 is the newest Minecraft version Minecraft Server API 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 Minecraft Server API support?

Everything the author has declared, from 1.18 up to 1.21.8. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Minecraft Server API on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

Which platform or loader does Minecraft Server API support?

Bukkit, Spigot, Paper. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Minecraft Server API?

On the newest Minecraft version it supports, Java 21 or newer. The requirement comes from the Minecraft version you run rather than from the plugin itself, so on an older supported Minecraft the answer is that version's Java, not this one.

What licence is Minecraft Server API under?

GPL-3.0-or-later, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Minecraft Server API?

Choose the release variant for your server platform. Paper, Spigot, Purpur and Bukkit files go in the server's plugins folder; Fabric, Forge, NeoForge and Quilt files go in the mods folder. Restart after installing and check that the Minecraft version matches your server.

Where do I download Minecraft Server API safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
