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
