Both the client and the server (warpd) seem to be in the repo. I agree there should be an explanation early in the readme because when I came to the part with IDs I immediately went 'wtf? does this go through their servers?'. Edit: Reading through some of the replies here it might actually be using their servers at least for the ID resolution.
