Join a server
Start HogwartsMPLauncher.exe, let it check for updates, then select a server in the main-menu browser. Click a direct-connect address on this page to open it with the installed ArcaneMP launcher. If your system has no handler for hogwartsmp:// links, copy the address into Direct Connect in the game. The default UDP port is 27015.
Check the advertised version and ask the owner about the release channel or required password. The current testing release is 1.10.0, but listings may advertise older builds. A listed server can still be unreachable or running a different build.
What this list shows
This page reads MafiaHub’s public masterlist and includes only entries identified as ArcaneMP (game ID HogwartsMP). Player counts, capacity, version, region, and password status are advertised by each server. It is not an independent connection test.
The page fetches current listings on request and refreshes every 30 seconds while visible. A failed refresh is marked explicitly and retains the last successful result. A genuinely empty masterlist is shown separately from a network failure.
Private or unlisted servers are absent from this directory and may still accept direct connections.
Bring your own world online
Register a server in the MafiaHub dashboard, put its private key in server-token, and make the game’s UDP port reachable. The runtime publishes its own announcements while running. Leave the token empty to keep a server unlisted.
Servers allow 32 players by default and up to 128. For public gameplay, install Foundation and its database before admitting players.
