SQL Card Data Lint (PCI DSS Req 3)

Names every column, index, view and seed row in a .sql migration that stores card data, with its PCI DSS Requirement 3 rule id

Install

npx @readystack/sql-card-data-lint file

Node 18+. The same 10 rules as the VS Code extension, from a terminal or CI.

Free

• Check the .sql file open in your editor against all 10 rules and get every card-data column, index, view and seed literal with its Requirement 3 rule id and a replacement line
• --rules lists every rule

With a licence ($29 once)

• Sweep every migration in the workspace at once and write a dated findings report you keep and hand to an assessor, for team and commercial use

@readystack/sql-card-data-lint --dir ./templates --report html --out report.html

A QSA-led gap analysis of your data stores is commonly quoted as a five-figure engagement; the same migrations are read here in the editor.
