About This MCP Server
We build AI-accelerated threat modeling and compliance tools for automotive OEMs, Tier 1 suppliers, industrial manufacturers, and critical infrastructure operators. This MCP server started as our internal IEC 62443 reference tool — turns out everyone securing OT environments has the same "6 documentation sites, 12 PDFs" problem.
So we're open-sourcing it. Navigating IEC 62443 security levels shouldn't require a spreadsheet and a law degree.
