Overview
Mappstack maps software systems. Claude reads and writes the same map you edit in the Mappstack web editor: C4 diagrams from system context down to code, data models, OpenAPI 3.2 specs, event contracts, job schedules, state machines and business capability maps. Every save is validated, and Claude can audit a project for gaps before designing the next part. Read tools run without confirmation. Tools that change or delete data ask first.
