Originally created and intended to be used for a more automated use of minecraft datapacks, in tandem with the FTP Deploy action. See this file for a working example of a combination of these two.

To set up with your Minecraft Server via FTP, copy the linked example file to your_repository/.github/workflow/main.yml, update and add the secrets to your repository and you're ready to go. That is if your server has both FTP and RCON enabled.

Example Action File

File in this repository

name: RCON Test

on: 
  push:
    branches: [ main ]

  workflow_dispatch:

jobs:
  rcon_test:
    runs-on: ubuntu-latest
    name: RCON Test
    steps:
      - name: RCON Connection
        uses: Plagiatus/RCON-Action@v0.1
        with:
          server: ${{ secrets.rcon_server }}
          port: ${{ secrets.rcon_port }}
          password: ${{ secrets.rcon_password }}
          commands: '["say hi", "reload"]'

Available Arguments

name	required	description	default	example
server	yes	The server IP		`127.0.0.1`
port	no	The RCON port	`25575`	`12345`
password	no	The password	`""`	`Sj3%ka"l`
commands	no	Additional commands you want to run, in the form of a JSON String Array		`'["say hi", "reload"]'`
send-push-info	no	Whether a tellraw informing about the push should be sent	`true`
push-info-recipient	no	Changes the selector of the push info tellraw.	`@a`	`@a[tag=admin]`

It is highly recommended to use github secrets instead of plaintext inclusions for more sensitive data like the IP or the password.
