How to Add Plugins and Mods to a Minecraft Server

Checked 9 November 2026

A Minecraft server on PlayRack takes your own plugins and mods, from the web page or over SFTP. First, know what your server software can run.

Plugins or mods

  • Plugins run on the server only, so friends install nothing. They work on Paper (Java) or Nukkit (Bedrock)
  • Mods change the game itself: every player needs the same mods and the same Forge version. They work on Forge (Java)
  • Java Vanilla takes neither

In the web page (the Files tab)

  1. Download the plugin or mod (a .jar file) from a source you trust, such as Modrinth, Hangar or CurseForge, for your server's version
  2. Open your server's page in the Client Area and go to the Files tab
  3. Open the plugins folder (Paper, Nukkit) or mods (Forge) and press Upload
  4. Restart the server and check its Console that the plugin or mod loaded

For big files or many of them, such as a whole modpack, SFTP is easier.

Over SFTP

  1. On your server's page, the SFTP box shows the address, port and login
  2. Open an SFTP app such as FileZilla or WinSCP and enter them
  3. Drag the files into plugins or mods
  4. Restart the server

If the server will not start

  • Read the Console for the file in the error, and remove that file from plugins or mods
  • Check the plugin or mod is for your server's version
  • Back up before adding anything new, so you can restore
