MongoMation
Built at The Harness Engineering & Model Wrangling #SFTechWeek Hackathon · Oct 11, 2026 · San Francisco, CA

MongoMation is an autonomous PLC engineer. You describe a machine in plain English, and Claude agents write IEC 61131-3 PLC code, compile and deploy it to a real OpenPLC runtime, and test it against a live Factory I/O simulation on AWS. When tests fail, the agent diagnoses them from measured sensor data and repairs its own code. Every stage is checkpointed in MongoDB Atlas, so runs survive crashes. A recursive self-improvement loop mines failures from Atlas and Raindrop to propose harness changes, which ship only if they beat a frozen benchmark on the real rig. The UI is a 3D control room with a live digital twin of the plant.
