Shure, the graphic was not called to be placed in the document!
So you might add  \useMPgraphic
This works here:

\setupoutput[pdftex]
\setupcolors[state=start]

\starttext
                 The simplest metapost code
         \startuseMPgraphic{test}
                 fill unitsquare scaled 123 withcolor (.2,.3,.4);
         \stopuseMPgraphic
              \useMPgraphic{test}
\stoptext
