Now I am using staticMPfigure. This is the final version

\def\startstaticMPfigure#1#2\stopstaticMPfigure
   {\bgroup
     \setMPrandomseedfalse
     %Otherwise randomseed := number line always differ
     \doifmodeelse{*pdf}
     {\def\executeMPTEX##1%
     {texmfstart --verbose --ifchanged=##1.mp texexec --mpgraphic 
##1.mp}
     \let\executeMPOST=\executeMPTEX}
     {\def\executeMPOST##1%
     {texmfstart --verbose --ifchanged=##1.mp bin:mpost

\ifcase\interactionmode\MPOSTbatchswitch\or\MPOSTnonstopswitch\fi
       \space\ifuseMETAFUNformat \MPOSTformatswitch metafun \fi ##1}
    \def\executeMPTEX##1% slower, due to nested texexec call
    {texmfstart --verbose --ifchanged=##1.mp texexec
        --batch \ifcase\interactionmode --logfile='mptex.log' \fi
        --output=\MPOSTdriver\space
        \ifuseMETAFUNformat --mpformat=metafun \fi --mptex --nomp 
--once ##1}}
     \def\MPgraphicfile{\jobname-#1}
     \newcount\currentMPgraphic
     \startMPgraphic
       #2
     \stopMPgraphic\egroup\deallocateMPslot\currentMPgraphic}

\def\usestaticMPfigure{\dosingleempty\dousestaticMPfigure}

\def\dousestaticMPfigure[#1]%
   {\doifmodeelse{*pdf}
   {\externalfigure[\jobname-#1.pdf]}
   {\externalfigure[\jobname-#1.1]}}

\starttext

\startstaticMPfigure{circle}
   fill fullcircle scaled 10cm;
\stopstaticMPfigure

\startstaticMPfigure{axis}
   drawarrow (0,0)--(1cm,0) ;
   drawarrow (0,0)--(0,1cm) ;
   label.llft(textext("(0,0)") ,origin) ;
\stopstaticMPfigure

\hbox to \hsize  \bgroup
\hss \usestaticMPfigure[circle][width=1cm] \hss 
\usestaticMPfigure[axis] \hss \egroup
\stoptext

Thanks,
