seams this code means to put a hidden text with same size behind 
metapost shape.
but it does not work properly for me (current version: 2024.04.01 08:59) 
and produce empty page but with searchable hidden text.
as mentioned kind = "outline" will be in the next upload so with the 
current one you need to use the also posted here for ... endfor variant
...
also when i edit the code and replace metapost part like this:
\startMPcode
      draw lmt_outline [
          kind = "outline",
          text = "\getbuffer[MyText]",
       ]
          withcolor red
       ;
\stopMPcode
it produces a selectable hidden text on top of body and red text that 
drawn by metapost below of that.
How can this problem be solved?
i attached the codes and pdf results.

    we're talking outlines so that is paths which implies no search but you
    can do this (Keith and/or Hraban will explain and/or wikify it)
\starttext
\startbuffer[MyText]
          \definedfont[name:texgyrepagellabold*default]foo f o o%
    \stopbuffer
\startbuffer[MyText]
          \framed[align=normal,frame=off]{\input{tufte}}%
    \stopbuffer
\setbox\scratchbox\hbox\bgroup
          \startMPcode
               draw lmt_outline [
                   kind = "outline",
                   text = "\getbuffer[MyText]",
               ]
                   withshademethod "linear"
                   withshadedirection down
                   withshadecolors (red, blue)
               ;
          \stopMPcode
    \egroup
\startoverlay
{\scale[height=\htdp\scratchbox,width=\wd\scratchbox]{\effect[hidden]{\getbuffer[MyText]}}}
          {\box\scratchbox}
    \stopoverlay
\stoptext
