Connects Discord and Minecraft Servers by sending messages back and forth without any mods or plugins.


This project has recently gone under a rewrite and the format for config.json is not directly backwards compatible with previous versions. See below for details.

In Action



  • Sends message to and from Vanilla Minecraft servers
  • Can send messages regarding advancements, when players join and leave, and player deaths
  • Allows admins to send commands to Minecraft through Discord

Installation and usage

Create a Discord bot here:

Then, add the bot to your Discord server using the following link, replace the Client ID with that of your bot.<CLIENT ID>&scope=bot

In your Minecraft, make sure you have the following and restart the server:

rcon.password=<your password>

Clone repository onto a server, edit config.json (see below for more info) and change any options. Then, in the repository folder:

$ yarn
$ yarn build && yarn start

If you are running this on the same server as the MC server, enable the IS_LOCAL_FILE flag and update related options below. Otherwise, perform the following command on the server hosting (in a screen/tmux session or background process, make sure to replace your YOUR_URL with whatever URL you're using (localhost:8000 if running on the same server and default config) and PATH_TO_MINECRAFT_SERVER_INSTALL with the path to the Minecraft server installation, such as /usr/home/minecraft_server/):

tail -F /PATH_TO_MINECRAFT_SERVER_INSTALL/logs/latest.log | grep --line-buffered ": <" | while read x ; do echo -ne $x | curl -X POST -d @- http://YOUR_URL/minecraft/hook ; done

(The above command will also be given to you if you are not using a local file when you start up Shulker)

You can also easily Deploy to Heroku and the like, just be sure to edit YOUR_URL in the command to match accordingly.

  • How do I make this work on a modded server?

    • Try replacing REGEX_SERVER_PREFIX with "\\[Server thread/INFO\\] \\[.*\\]:"
  • Why can't I send commands even if I have the option enabled?

    • Make sure that you have a role on the server which is put in the array SLASH_COMMAND_ROLES case-sensitive.
      • e.g. "SLASH_COMMAND_ROLES": ["Admin"]

Upgrade Instructions

From version 2 to version 3:

  • The main change is that you need to split your REGEX_MATCH_CHAT_MC to both REGEX_MATCH_CHAT_MC and REGEX_SERVER_PREFIX. See the configuration above for details.
