Enables AI agents to validate Mexican RFC, CURP, CLABE and NSS identifiers with real check digits, parse CFDI 4.0 invoices with labelled SAT catalogue codes and verified totals, and query the SAT's public status service to see whether an invoice is still valid. It also generates coherent test people and companies, all read-only and without API keys, certificates or PAC contracts.
