  We document several recent updates to the MCPLOTS event-generator validation
resource. The project is based on the RIVET analysis library and harnesses
volunteer computing provided by LHC@home to generate high-statistics MC
comparisons to data. Users interact with the resource via a simple website,
mcplots.cern.ch, which provides flexible options for requesting comparison
plots and comprehensive statistical analyses on demand, all in a few clicks.
The project has been structured to enable community-driven developments, and we
discuss the computational back end, the web front end, and how to add new data
analyses, generators, and tunes that would be accessible on the website for
comparison.
