CrabCity v5.x Authentication Mod

by CrabCity

CrabCity v5.x Authentication Mod lets a Fabric server check players against the CrabCity API across servers, using a token file kept in the server root.

FabricServer-side onlyAll rights reserved1.19.2

What it does

Once the server holds a valid token, the mod authorizes players through the CrabCity API, so access can be checked across more than one server. Setup is done on the server only: install the mod, request the server token from HeyCrab3, and store it in a text file in the server's main folder.

The token file must hold a single row and nothing else. Clients do not need the mod, so players join without installing anything. Fabric API is required and must be installed alongside it on the server.

The mod is published for Fabric only, for 1.19.2. Its only build is version 1.0, released on 2026-02-09, and the mod was first published and last updated on that same date. Its code is under All rights reserved and is not open source.

Key features

  1. Cross-server authorization

    Players are authorized through the CrabCity API, so one check can apply across several servers.

  2. Token-based setup

    The server authenticates with a token obtained from HeyCrab3 and stored in a single-row file in the server root.

  3. Players join unchanged

    Only the server runs the mod, and connecting clients need nothing extra installed.

Use cases

Multi-server networks

A server network that wants a shared authorization check can give each server the same token setup and rely on the CrabCity API for the lookup.

Who it’s for: Server owners who operate a Fabric 1.19.2 server and hold a CrabCity token are the intended audience. Players on such servers do not need to change anything on their own installs.
