clientjoinserver
by moddedmcnet
clientjoinserver is a Fabric mod that connects players to a server automatically once the game starts, and it can grant first-join rewards.
What it does
When a player starts the game with the mod installed, the client connects to the configured server without any manual step. The server can send the name of the modpack to the client, so the server recognizes which pack is in use. Both the server and the client side need the mod for these functions to work, and a player who has the mod installed is recognized on join.
First-join rewards are handled by configurable commands that the server runs when a player joins for the first time. The commands accept placeholders, and each reward is tracked once per player so it is not granted again. Players without the mod receive a friendly reminder with a clickable link. The mod is compatible with Velocity and TCPShield proxies, and it is published for Fabric 1.21.1 only.
Client and server installation is required: the server and every player need it. Files are published for Fabric in one release, 1.1 for 1.21.1, dated 2025-09-20. The code is not open source; the mod is released under All rights reserved.
