Hi David,
without digging into depth, it works if you change MPpage into TEXpage

because you nest a graphic, kind of
beginfig(1) beginfig(2) draw unitsquare scaled 4cm; endfig ; endfig ;

because
(1) after startMPpage metapost code is expected (or something like
\includeMPgraphic{...} that expands to mp code
(2) when the setup is moved outside the startMPpage, contex does not
know what vars to preset
however, this works (MPrawvar is undocumented, yet)
\startuseMPgraphic{usquare}
draw unitsquare scaled \MPrawvar{usquare}{u};
\stopuseMPgraphic
\starttext
\setupMPvariables[usquare][u=4cm]
\startMPpage
\includeMPgraphic{usquare}
\stopMPpage
\stoptext
