mIRC logo

mIRC is a shareware Internet Relay Chat client for Windows, created in 1995 and developed by Khaled Mardam-Bey. This was originally its only use, but it has evolved into a highly configurable tool that can be used for many purposes due to its integrated scripting language. Other uses include:

  • Automated IRC channel manager
  • Multiplayer game server
  • MP3 player
  • Web page parser (usually for retrieving search results or headlines)
  • DCC, HTTP, and IRC server
  • Game platform (these games are called mIRC games)

A highly popular program, it has been downloaded more than seven million times from CNET's ( service as of 2004. Neilsen Net Rankings ( also rated mIRC as among one of the top 10 most popular internet applications in 2003. Its popularity may explain why many mIRC users mistakenly believe that the name of their client is also the name of the protocol it uses, thinking they are "connecting to an mIRC server" or "joining an mIRC channel".

The latest version of mIRC is 6.16 and was released in July 7, 2004.


Main features

  • Connection to multiple servers simultaneously (added from version 6.0)
  • Advanced integrated event-based and command-based scripting language
  • Basic CTCP support
  • CTCP SOUND support (can play MP3, WAV, and MIDI)
  • DCC chat and send support
  • Attempts to stop inadvertent Trojan horse downloads
  • File server (operating over DCC chat) that allows a user to browse a specified folder and download files
  • ANSI-style and mIRC-style text decoration support
  • Speech recognition and synthesis via 3rd party products

Common criticisms

  • mIRC scripting allows troublemakers to dupe na´ve users into entering dangerous commands
  • Khaled Mardam-Bey did not consult others when developing mIRC-style text decoration like colors; this may be why some IRC client authors have not included support for it
  • Exploits causing mIRC to crash remotely via sending an unexpected command have been discovered forcing users to upgrade. This is merely a minor annoyance as these have been fixed promptly.
  • mIRC does not support Unicode.
  • mIRC is free for use, so long as one can click through the main advertisement to register mIRC after 30 days of use. This is contrary to popular belief that mIRC must be paid for.

Slap! function

A famous (and now often considered annoying) feature particular to mIRC is the ability to "slap" another user by right-clicking the target's nickname. This results in the line of text "A slaps B around a bit with a large trout". It serves no other function than to send the message, which is merely an execution of the "/me" command in IRC. Such an action can warrant a kick or even a ban in many channels.

This function can be removed by editing mIRC's built-in script.
