Why This Exists

PCI DSS 4.0 took effect March 2024 with 64 new requirements, many of which become mandatory by March 2025. Any organisation that stores, processes, or transmits cardholder data must comply, and AI systems that touch payment flows (fraud detection, transaction scoring, customer authentication) bring new scoping challenges.

The 4.0 revision introduces targeted risk analysis, customised approach validation, and stricter requirements for scripts, headers, and client-side protections. Most QSA-led assessments cost $50-200K. This MCP assesses compliance across all 12 requirements, analyses cardholder data flows, validates network segmentation, checks vulnerability scanning posture, and generates the appropriate Self-Assessment Questionnaire.
