ms-to-mca

Simplifies the process of logging into Minecraft services on behalf of a Microsoft user. In order to use this library, you will need to create an app that interfaces with the Microsoft Identity Platform. The easiest way is using an implementation of the Microsoft Authentication Library (MSAL).

Once your app is set up, request an access token from the user (that's what you'll need to use this library). Be sure to ask for the XboxLive.signin scope! It's required for logging in to Minecraft.

Disclaimer

Firstly, Minecraft access tokens can be dangerous! Tokens grant an application full permissions to a user's account, meaning they can...

• connect to online-mode servers on the user's behalf

• change profile info...

• username

• capes

• skins

I strongly recommend you provide a similar disclaimer to users logging into your own app, both for their security and to raise awareness of the dangers of Minecraft authentication with third-party apps.

Secondly, this is NOT a Minecraft API library. Its only function is exchanging Microsoft access tokens for Minecraft ones, which can be used to perform actions on behalf of a Minecraft account. To interface with the rest of Minecraft's online services you'll need a separate library of your choice.
