What the fuck is up with you tech?!
Are you this illiterate?
LSP describes an interface for smart code linting and auto suggestions. It has absolutely nothing to do with a server in terms of web.
Instead hoping, that your text editor supports for instance GCC's Linting (in terms of SublimeText via Sublime-Linter GCC) you simply get the Sublime LSP , which interprets the LSP info.
Now you can use Clang or ccls for instance to check you code and give linting and auto suggestions.
Sublime text for instance is too retarded to auto-complete commands from C libraries, but LSP allows clang to pull that information and auto complete all Parameters of a command from that library.
This is not possible with GCC's build in linting.
TL;DR, instead of hoping that your text editor does magic, it only needs to support one protocol and eg. Clang scans your code and provides linting to your text editor.
