The AGPLv3 is exactly the same as the GPLv3, except with the added clause that connecting to a server counts as distribution for the purposes of triggering the right to obtain source code.

That means all the usual GPL copyleft rules apply: if you include an AGPL library in your server binary, the entire binary becomes subject to the AGPL. And being subject to the AGPL, you are obligated to provide access to the source code for your entire server binary to anyone who connects to and interacts with your service across a network.

Quoting from https://www.fsf.org/bulletin/2021/fall/the-fundamentals-of-t... :

> Simply put, the AGPLv3 is effectively the GPLv3, but with an additional licensing term that ensures that users who interact over a network with modified versions of the program can receive the source code for that program...

> These terms cover the distribution of verbatim or modified source code as well as compiled executable binaries. However, they only apply when a program is distributed, or more specifically, conveyed to a recipient...

> The AGPLv3 does not adjust or expand the definition of conveying. Instead, it includes an additional right that if the program is expressly designed to accept user requests and send responses over a network, the user is entitled to receive the source code of the version being used.
