Overview
MCP LatAm Tools is a compliance layer for AI agents operating in Latin American markets. It provides instant validation of tax identifiers, payment keys, and public holidays across Brazil, Mexico, Chile, and Argentina — with no external API dependencies and no API keys required.
Designed as the entry point for Latin American data validation: 11 essential tools, Pro tier $9/month for 10,000 calls. For full invoice/VAT helpers, business rules, e-invoicing, and 5-country coverage (BR/MX/CL/AR/CO), see the MCP LatAm Business Suite.
Why use MCP LatAm Tools?
AI agents handling Brazilian invoices, PIX payments, Mexican RFC checks, or AFIP onboarding flows need to validate data in real time. MCP LatAm Tools integrates natively via MCP, so any agent can call these tools without custom connectors or API keys.

Notes on use
This server provides deterministic algorithmic validation (checksums, format checks, holiday calendars) and reference data for basic Latin American data validation in AI agents and automated workflows.
It is designed to catch format errors before they reach production systems — invalid CPF/CNPJ/RFC/RUT/CUIT/CUIL, malformed PIX keys, scheduling on non-working days across BR/MX/CL/AR.
The data is updated periodically and reflects published regulations at the time of release. For NF-e/CFDI/DTE generation, complex tax situations (cross-border edge cases, ICMS/ISS sector-specific rules), or audit-grade compliance, consult a tax professional, your local tax authority's official systems (Receita Federal, SAT, SII, AFIP), or upgrade to the MCP LatAm Business Suite for invoice/VAT helpers, business rules, and 5-country coverage including Colombia.
