thanks everyone for the feedback! With it I managed to use the
%(expression) in org-agenda-prefix-format to show the breadcrumbs. In
case that's useful for other people too, I attached a patch that adds a
%b option to org-agenda-prefix-format to does the same. Would be great,
if this could be included.

Subject: [PATCH] added option %b to dispaly breadcrumbs in agenda

if org file has the structure

* project
** task1
*** TODO item1

then when using %b in org-agenda-prefix-format will display
project->taks1->TODO item1
