A lightweight validation toolkit that gives Claude five checksum tools for common identifier formats: IBAN bank accounts, ISBN book codes, EAN/GTIN product barcodes, UUIDs, and ULIDs. It's stateless and deterministic, so you get the same answer every time without needing auth tokens. The server caps free usage at 500 tool calls per IP per day, which should cover most agent workflows. Reach for this when you're building workflows that handle financial data entry, inventory systems, or any pipeline where you need to catch malformed identifiers before they hit a database. Deliberately skips payment card validation to keep things focused on public identifier standards.
