Modpack Shipped Servers

Modpack developers define a set of default servers in the mod's data, and each entry carries a name, an address (an IP or a domain) and a resource pack policy. When the mod first runs, it checks whether server data already exists, and if none is detected it adds the servers from the modpack. Each server can be switched on or off, and a prompt can ask the player whether to keep it, so players stay in control of what appears in their server list.

The mod is useful for modpacks that advertise a recommended list of servers, since the developer can provide the list instead of asking players to add each address by hand. It runs on the client alone, so players install it inside the modpack and no server software is involved. The mod is open source under the MIT License and requires Fabric API. Files exist for Fabric across 23 release versions, 1.20 – 26.3, with snapshot builds published alongside the releases.
