If this has been posted before, I apologize, it has been a long time since I've been on these forums.

Here is how to get a direct connect url for any minecraft classic server and bypass the sign in screen that's causing so much trouble.

  • Open up a notepad file (or any text editor of your choice)
  • Login to
  • Click on your server
  • When the server comes up, right click outside of the game area and click 'view page source'
  • Press "Ctrl + F" on the source page, and type in "mppass" (without quotes), copy and paste the number that appears after value=" into your notepad file. (The number should look something like 76a80e153ba559984d43cb55055e) (this is an example, not my actual value, never give out your actual mppass to anyone)
  • Look for the IP Address, a few lines above the mppass, and paste that into your notepad file (it will look something like
  • Look for the Port, just below the ip, which should be a number between 0 and 65536, and paste that into your notepad file (should look like 25565)
  • Open up World of Minecraft Client, and in the Direct Connect URL box at the bottom, paste in your values with the format of: 


(Put them in this format in the notepad file, then ctrl+v them into World of Minecraft.)

In this example I would use:


After you get that in, just click 'go' and you should be logged into the server that you got the mppass ip and port from.

With this method, you should be able to save the file formatted like that into notepad and paste it into World of Minecraft any time you want to log in to your server.

Credit for this method to Johnnyli1125 (I read it on his site, but reworded it to make it as easily understandable as I could).

If you have any questions or issues, let me know, I'd be happy to try to help.

JavaScript method

I remember I made a javascript to automate that process.

  1. In your web browser, add a new bookmark. Example of the title could be "Get World of Minecraft URL".
  2. As the address (URL) of the bookmark, enter the code provided below (all of it), then save the bookmark.
  3. Go to the server you want to play on in browser.
  4. Open the bookmark.
  5. Copy the mc:// url you get in the dialog box!

Here is the code line to use as the address in the bookmark:

javascript:var womCode;womCode = 'mc://' + document.getElementsByName("server")[0].value + '/' + document.getElementsByName("username")[0].value + '/' + document.getElementsByName("mppass")[0].value;prompt("Here's your World of Minecraft URL:",womCode);


Does the URL box not appear? Look in your browser for a bar asking if the script is allowed to ask you for information (it doesn't do that, but because I'm using a prompt, it thinks I am). Allow it, then try again. (I only encountered this problem in IE 6 yet.)

If it still doesnt work, make sure you are not blocking JavaScript in your browser then try again.

Hope it helps!

There are many topics stating why it's not working has changed from urls to ones, breaking the pieces of code that go to the ones (i.e. the ones that sign you into your account).. As explained in this topic, here of Minecraft-authentication-fix.


So, either you can try this method, or try another, like launcher x from au70, or wait for an update (which is something that hasn't happened in a long time.)

I've used this method before and I have the same problem, usally what I do is use XWoM Then log in

then go into a server then x out of XWoM then go into the real World of Minecraft then click resume thats how I do it.

also its less hard
