Polymorph goes on both sides: on the server and in every player's Minecraft. Easy: the panel's .mrpack modpack already includes it.

How to add Polymorph to your server

  1. Open the panel and create a world with a compatible loader and Minecraft version (Fabric, Forge and NeoForge, per the table above), or open one you already have.
  2. In the world's "Mods" section, search for Polymorph in the Modrinth catalog. You'll only see what works with your world.
  3. Add it with the "Server and players" option, the one the panel suggests for this mod.
  4. Start or restart the server so it installs.
  5. Ask your friends to download the .mrpack modpack from the panel again.
