⬇️ Installation

1- Enable the Server Management Protocol/Management Server in your server.properties file.

management-server-enabled
- default false
- set to true
management-server-host
- default localhost
- keep set to localhost
⚠️ Warning
Ideally you keep this set to localhost and only run services that need to access the server on the same machine.
If you trust everyone that's connected to your local network (you shouldn't!),
then set to 0.0.0.0 to allow other machines on the same network to access the server.
management-server-port
- default 25585
- set to an unused port if the default port is taken by another service on your machine
🚫 Caution
DO NOT FORWARD THIS PORT (Port-forwarding).
There is no authentication built into the management server and anyone that can connect essentially has full control over your server.
You're recommended to run services that use it on the same machine and keep management-server-host set to localhost.

2- Download this mod, making sure to match it to the minecraft version of your fabric server.

3- Add the downloaded .jar file of this mod into your mods folder in your server, and start/restart.

▶️ Usage

You can use this with anything that can connect over websockets.
This example uses Node.js, specifically the wscat package.
If you want to follow along, make sure to first install Node.js and NPM
(NPM should be automatically installed alongside Node.js).

Install properly onto your Fabric Minecraft server as detailed in Installation and run the server.
Open a terminal application.
Install wscat globally using NPM if you haven't already: npm install -g wscat.
Run the command wscat -c ws://<management-server-host>:<management-server-port>
Log into your Fabric Minecraft server with your Microsoft account.
Send a chat message in-game, and you should see a notification pop up in the terminal application with relevant information.
