AFAIK there's no way to get the list of plugins directly from the build hash. But if you have access to a UNIX shell, save the following shell script as find_plugins.sh
:
#!/bin/sh
for PLUGIN in \

do
grep -q -F $PLUGIN $1 && echo $PLUGIN
done
Then run it like this passing the filename of your MooTools More file as first argument:
sh find_plugins.sh mootools-more.js
It will print out a list of all plugin names found in the JS code. That should get you started.
