Nowadays, people cheat a lot in Minecraft. As they want to play more and cheat even more, websites like MCLeaks provides Minecraft accounts for free. This is a problem: it means a cheater is able to reconnect indefinitely to a server—maybe your own!—and continue to cheat. Even if these services are totally legal because they run with thousands of accounts given by their respective owners, the question is, should we tolerate this and accept these players, or do we have to ban them to protect ourselves against the cheaters using these services?

We provide a RESTful API, taking an UUID and answering if this UUID exists in the database or not.

https://doha.blueslime.fr/api/check/<UUID>

As example,

https://doha.blueslime.fr/api/check/29b2b527-1b59-45df-b7b0-d5ab20d8731a

answers,

{
  "exists": "false"
}

If you are a -big- Minecraft server and you think that you will make easily 100k requests a day, this section is for you!

In your case, it's maybe easier for you, and more friendly for my server, to cache locally the database (located in the db.json file). Don't forget to refresh your cache from time to time to get the new players from the list.

Feel free to contact me if you have any questions about how to create this cache.

This is a public database, and even if we are working on a bot to automatically fill this database, it will be faster if you help us!

Go to the MCLeaks website and redeem an ALT-Token. After, send a request to:

https://doha.blueslime.fr/api/ban/<ALT-TOKEN>

If the token is still valid, the account will be added to the database and be blacklisted immediately (it can take 1 hour to update this repository—crontab yee).

Also, we created a Google Chrome extension to help us and it's works very well! All the explainations on the Google Chrome Web Store.
