Who can I ask about usage rights?

I want to start a gaming project (server), make everything legal, etc. And a question about usage rights has surfaced.
So I do not want to make a normal minecraft server, but with mods that everyone can download the launcher and play it. In Russia e.g. Is it a normal thing. But in Germany there are no such projects and that has unsettled me.
Can you please send any websites or e-mail addresses people suspected of having?

Ja

Could you explain the problem in more detail?

So in Russia there are many servers with mods, you can just go to the website, register and download the launcher. You do not have to buy the game and still play, even if only on this one server.
In Germany, however, there are no such projects, is that because it is illegal?
I'm now insecure and want to ask someone who has any idea if it is legal. Because such projects allow anyone to play who has not bought Minecraft.

Ja

Yes, it is not legal in Germany.

So if I authorize Mojang so that only people who bought Minecraft can play, would it be legal?
Have seen the technicpack.net do the same.
