IRC is Internet Relay Chat.

MinecraftOnline has an IRC channel for realtime public discussion:

  • Channel: #minecraftonline
  • Network:


The control panel IRC client
Staff chat in IRC
A message from a IRC bot viewed from ingame
  • Channel news in the topic, with useful links
  • Moderators and admins are channel ops.
  • Staff messages are broadcast as op messages to staff, and can be replied to via irc.
  • A selection of bots available for convenient assistance (see below).


There is a selection of bots running in #minecraftonline at any time. They may be given mode +v (voice) to separate them on the users list.


McObot is an IRC bot designed specifically to relay messages between the game server and the MinecraftOnline IRC channel. It was written by Flippeh and SlowRiot in Python.

  • It relays all in-game chat to the IRC channel, and vice versa.
  • It relays in-game events such as joins and quits to the IRC channel.
  • It relays player deaths ingame with custom death messages relating to what caused the death.
  • It provides notifications of other interesting events:
    • Automated backups
    • Banhammer use, and ban count
    • Donation events
    • Firewall mitigations of attacks
    • Live code updates and changes, with changelog information
    • Shortens URLs pasted in IRC for easier in-game access
    • Detects foreign speech, identifies the language and translates it
    • Code and issue tracker updates.
  • It provides additional control and information commands:
    • !commands - shows a list of the bot's available commands
    • !list - displays a list of the players in game.
    • !tslist - displays a list of the players in TeamSpeak
    • !uptime - queries how long the minecraft server has been running for.
    • !radio - gets "now playing" information from MinecraftOnline Radio.
    • !stop justification (chanop only) - forces the server to attempt to shut down cleanly and restart - should be used in emergencies only and with very good justification.
    • !pipe on|off (chanop only) - activates or deactivates transmission between the game and IRC. Using just !pipe will show if the pipe is on or off.
    • !why player - checks ban logs for a given player's ban reason.
    • !map x [y] z [dim] - Produces a quick map link for a set of coordinates. Specifying y and dim are optional.
      • !map warp - Produces a map link for the given warp.
    • !whereis player - (chanop only) - reports the coordinates for a given player.
    • !locate player - (chanop only) - shows the map link for the location of player.
    • !whydidyoucrash (chanop only) - uploads a pastebin of the server's last crash report.
    • !healthyself (chanop only) - tells the bot "physician, heal itself" (which causes it to restart).
    • !stalk IP|username (chanop only) - get whois and abuse report info for the network of a given IP address or a username.
    • !drop IP (chanop only) - add a firewall rule to disregard all communication from a given IP.
    • !version - report the currently running server software version and the current vanilla version.
    • !servertime - report what the current time is in the server's timezone.
    • !bitcoin - report the current Bitcoin prices in GBP.
    • !shorten URL - produce a shortened version of a given URL.
    • !ping - basic confirmation message to check the bot can hear you and respond.
    • !translate language message - translate message into language.
      • !toggle_translation language (chanop only) - Toggles the translation of a language into English in chat.
    • !pirate YouTube link - turns the video on the link into an MP3 file.
    • !vote - shows list voting websites.
    • !areainfo x [y] z [x2 y2 z2] (chanop only) - shows protected [LionsArea|areas] at given coordinates or within the given range of coordinates, with y coordinate being optional if only specifying one location.
  • Staff channel in-game messages displayed to all channel ops on #minecraftonline.
  • Ability to message to the staff channel in-game with /msg @#minecraftonline (or your client's equivalent message command).
  • Messages prefixed with # in IRC will not be sent in-game, allowing "private IRC chat" without turning off the pipe.
    • Messages prefixed with \# in IRC will be sent in-game, but just starting with #, without the \.


  • For a long time, changing the topic in the channel would cause the bot to spontaneously die (although this is no longer the case).
  • McObot used to provide the !item command, when player inventory loss was frequent due to client-side inventories and frequent client crashes, although this functionality has since been removed.
  • The McO in McObot stands for MinecraftOnline; however, the Mc also serves to make him sound more Scottish.

How to connect

At the current time, to join IRC you must either register and identify with NickServ, or be invited. Registering with NickServ will also protect your nickname.

To connect to IRC you need an IRC client; many are available for free download, and some even run within your browser.


None. There are no rules on IRC. However, free speech does NOT apply, as it does in-game. Therefore you may be kicked or banned from IRC at a moderator's discretion. Usual reasons for bans are spam, excessive whining, trolling and general abusive behaviour. However, most moderators and admins are quite tolerant, and IRC bans are rare.


The network was chosen for purely pragmatic purposes - because this is where Notch's official #minecraft channel also resides, making it easier for existing minecraft IRC users to connect. Unfortunately, like most of Notch's decisions, this one showed remarkably little forward planning. Esper is notorious for its frequent netsplits and server failures. However, also like most of Notch's decisions, it's now too late to reverse, so we have to make the best of it.
