The work of MCnet is divided into Projects. Pythia, Herwig and Sherpa are all projects to develop the physics models and implementations of general purpose event generators and support their use by the LHC experiments and elsewhere.

MadGraph and Ariadne are projects to develop implementations and alternative approaches to two of the most important steps of event generation: automated hard process generation and parton showering evolution, particularly in the high energy limit.

CEDAR is a more general project aimed to provide general-purpose facilities to do high energy physics analysis and phenomenology. Among its many sub-projects, Rivet and Professor are particularly important for MCnet, providing generator-independent frameworks for comparison of event generator predictions with corrected data and for tuning event generator parameters.
