I have not tried it; but some web searching indicates that it is possible
to install MediaWiki to be below /embed/ on the embed.domain.com server;
and you might also be able to set $wgServer to tell it that it "really" is
on the docs.domain.com server, and you can optionally set $wgSquidServers
so that MediaWiki will use the X-Forwarded-For header.

In that case, the nginx side would basically be

location ^~/embed/ {
proxy_pass http://embed.domain.com;
}

And you might want to include "proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for;" or similar things too.

Also in that location{}, you would do whatever tests you want, to see if
this request should be allowed or not. That might be an "if $cookie",
or a fuller auth_request, or something written in one of the embedded
languages.

In this case, the first allow-or-not decision is made on the nginx side,
without involving MediaWiki at all.

I don't think a MediaWiki code change would be needed. There might be
useful config changes that could be made, but may not be compulsory. I
suspect that things would work more cleanly if MediaWiki knows that it
is below /embed/ instead of being at /; but it might be possible to work
in the latter case.

Good luck with it,
