Developer FAQ, PC server announcement
Using a server across PC stores
The dedicated-server update allows those PC versions to join the same server, but the host must configure the server for that connection method. Follow the README.txt shipped with Core Keeper Dedicated Server for the matching server version. The official announcement points existing hosts to that file as well. Official server instructions
For a modded session, the announcement says players need the same mods. Check the server’s connection instructions instead of assuming a Steam-specific join method works on another store.
Microsoft Store does not mean Xbox console
The server announcement names Microsoft Store as a PC storefront. Owning the Xbox console release does not put that player into the supported PC group.
This is a compatibility guide; use the server’s bundled instructions for installation and network configuration.
