⬇ Download on Modrinth
ServerFetcher is a lightweight client-side Fabric mod for Minecraft 1.21.1 that automatically fetches a server IP address from a predefined HTTP endpoint when the game starts and adds it to your multiplayer server list.
This is especially useful for dynamic or frequently changing server addresses, such as those hosted on ngrok or other tunneling services.
# 🔧 How It Works
When you launch Minecraft with this mod installed:
It sends a GET request to a static URL (e.g., https://example.com/ip).
The response should be a single line containing a valid Minecraft server IP or domain.
The mod then automatically adds (or updates) this IP in your servers.dat as a multiplayer server entry named "New Server" - can be changed in the config with ModMenu.
# 📁 server.py (Required for Hosting the IP)
To provide the dynamic IP to clients, you’ll need a simple HTTP server that serves the current Minecraft server IP.
Use the included server.py script from the GitHub repository:
python server.py This script:
- Hosts a small web server on 0.0.0.0:5000
- Returns the IP address stored when /ip is accessed
# Example ip.txt content:
7.tcp.eu.ngrok.io:12345
When a player with the mod starts Minecraft, it reads this IP and adds it to their multiplayer list automatically.
