I assume you mean in FPC/Lazarus ??? )(otherwise off-topic for the forum)

Did you use the search-function of the forum here?

Some are Delphi only, but most work with FPC/Lazarus:

I can't find some good serve.

I found at least 2 server codes in that list.
What was wrong with them?

Because if you can't tell us that, we can't advise you.

you can install mosquitto and mosquitto-dev. One of the links contains Pascal headers for it. That is more or less the official code and runs on Raspberry Pi OS and Ubuntu on Raspberri Pi. (All of them, 1 to 5)
See here:

I played with it yesterday. It is in the default repository.
(This is client code, but a server can be written with it is well )

I think this is a good choice, working here. Some dependencies can be easier solved,  but it is working for years here.
