Of course.

1. For a moment I set
   shell_escape =			f
in `kpsewhich texmf.cnf'

2. Input file f.tex:
\startuseMPgraphic{A}
   draw unitcircle scaled\overlaywidth;
\stopuseMPgraphic

\defineoverlay
   [B]
   [\uniqueMPgraphic{A}]

\starttext
   \framed[background=B]{Hallo frame!}
\stoptext

3a. classical run
   texexec --pdf f

3b. step by step
   texexec --pdf --nomp f
   mpost f-mpgraph
   texexec --pdf --nomp f
