Hi,

There is a good overview of accessible variables at:
https://tex.stackexchange.com/questions/134474/context-part-chapter-section-and-subsection-names

Maybe you want something like this?

\starttext
\setuphead[chapter][number=no]
\startchapter[title={My Chapter}]
Hello world!
\startMPcode
label("\currentstructurelistnumber\ \currentstructuretitle", origin);
draw fullcircle scaled 3cm;
\stopMPcode
\stopchapter
\stoptext

Adam
