Cobblemon Ori Starlight server files
No. Cobblemon Ori Starlight has no separate server pack on Modrinth, so the server is built from the .mrpack: the Fabric server for Minecraft 1.21.1, plus the pack's overrides folder and the server-side mods its modrinth.index.json lists. A modpack installer does this for you; our guide shows how to make a server for a modpack with no server pack.
