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
