What's wrong with
$ ssh myuser@remotehost 'mkdir /path/to/MyRepo.git; cd $_; git init --bare'
$ git push --all git@remotehost:MyOtherRepo.git
?

There's no such thing as git-prompt.  The restricted login shell for
SSH-only access typically used for such a "virtual" Git user is
git-shell.

It's not really clear what do you want to achieve.
The reason the git-shell shell is *restricted* (read its manual page)
is to shrink the surface of possible attacks in the case the shell
account used for accessing Git repos over SSH is compromized (the key or
password stolen, for instance).  This is achieved by only allowing
commands like git-upload-pack etc in the shell (no general file
manipulation commands etc).  So what creating "git command that can
talk to the server using git-prompt ..." would really buy you?

I think the way to go is to start using gitolite [1] or implement by
hand a subset of what it does (a custom login shell which is allowed to
do certain things in a special area of the filesystem designated to keep
Git repositories) or just set up a special account on the server
("git-admin", for instance) which would have a regular login shell set
for it and would be in the same group as the user "git" (or even have
the same UID) so that they could share the files they create (subject to
active umasks of processes run as both users though).
