AI agents call validate_cuit to retrieve information from Mcp Latam Business without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure validation/query tool that checks the format and checksum of a tax identification number. It retrieves no sensitive data, makes no modifications, and has no destructive or transactional side effects. The worst-case misuse would be validating arbitrary CUITs, which poses minimal risk. Classified as Read with low severity.
From the tool's definition Tool performs validation only: 'Validates an Argentine CUIT', 'Applies the official weighted modulo-11 checksum algorithm', returns boolean result with no state modification.

Validates an Argentine CUIT (Código Único de Identificación Tributaria) — the tax identification number for companies, self-employed workers, and legal entities in Argentina, issued by AFIP (Administración Federal de Ingresos Públicos). Applies the official weighted modulo-11 checksum algorithm. Returns { valid: boolean, cuit: string, type: string } or { valid: false, reason: string }. CUIT prefix identifies entity type: 20/23/24/27 for individuals, 30/33/34 for companies. Use when processing Argentine invoices, supplier registration, or AFIP compliance workflows. It is categorised as a Read tool in the Mcp Latam Business MCP Server, which means it retrieves data without modifying state.
