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.<\/p>\n
This is especially useful for dynamic or frequently changing server addresses, such as those hosted on ngrok or other tunneling services.<\/p>\n
### **# \ud83d\udd27 How It Works**<\/p>\n
When you launch Minecraft with this mod installed:<\/p>\n
It sends a GET request to a static URL (e.g., https:\/\/example.com\/ip).<\/p>\n
The response should be a single line containing a valid Minecraft server IP or domain.<\/p>\n
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.
\n###
\n### **# \ud83d\udcc1 server.py (Required for Hosting the IP)**<\/p>\n
To provide the dynamic IP to clients, you\u2019ll need a simple HTTP server that serves the current Minecraft server IP.<\/p>\n
Use the included server.py script from the GitHub repository:<\/p>\n
python server.py
\nThis script:<\/p>\n
– Hosts a small web server on 0.0.0.0:5000
\n – Returns the IP address stored when \/ip is accessed<\/p>\n
### # **Example ip.txt content:**<\/p>\n
7.tcp.eu.ngrok.io:12345<\/p>\n
When a player with the mod starts Minecraft, it reads this IP and adds it to their multiplayer list automatically.<\/p>\n
\u2699\ufe0f Requirements<\/p>\n
– Minecraft 1.21.1<\/p>\n
– Fabric Loader<\/p>\n
– Cloth Config API
\nClient only (does not need to be installed on the server)<\/p>\n
