is there a way to communicate testcafe with my local server?

I have been trying testcafe and I would like to emulate this behavior:

1- launch testcafe from a local script(easy part, no problem)

2- Post instructions to testcafe server (Posting to Proxy Serv? using BrowserProvider API?)

3- get a response from the posted instructions

Scripting tests for testcafe is fairly easy using the common examples and tutorials, but the expected behavior for this particular case is triggering the instructions in real time. I am kind of lost in this one and the Documentation is kind of confusing with the Advanced Tutorials.

I would like to know options or actual implementations of the problem
