FediLookup
by seercat
FediLookup lets players link a Minecraft account to a Fediverse address and look up the address of any other player on a server.
What it does
Players set a Fediverse address that is tied to their Minecraft account. Other players can query that address by name, and the mod shows the address a given player has set. Autocomplete lists every player with a stored address, including players who are offline at the moment, and also lists the Fediverse addresses already known to the server.
A reverse search goes the other way: given a Fediverse address, it returns the Minecraft user associated with it. The mod runs on the server only, so players join without installing anything. Fabric API is required on the server. The current build is 1.3.0 for 1.21, released 2024-07-18, and the mod is open source under the MIT License.
Account data is kept in a separate file next to the main configuration, so the stored links persist between server restarts. An operator can reload the main configuration at runtime with the fedi reload-config command. The mod has no options that change its behavior at the moment. Editing the data file by hand is possible, but doing it while the server is shut down avoids conflicts.

How it compares
UsernameIpLock is a server-side Fabric mod for 1.21 – 1.21.11 under a Creative Commons Attribution No Derivatives 4.0 license, so it is not open source. ServerListSync is a client-side Fabric mod for 1.18.2 – 26.2 under the GNU Lesser General Public License v3.0 or later and is open source. Neither mod links accounts to Fediverse addresses, so the two cover different tasks from FediLookup.
