wtf is latam-data-mcp?

This project is an MCP server, a small local program that gives AI assistants like Claude access to a specific set of tools. In this case those tools are all about Latin American data that is normally scattered across many sources, written only in Spanish, or otherwise hard for an AI agent to reach on its own. The server offers 20 tools in total. One group handles identity and business checks: validating national tax IDs with real check digit math across 15 countries, checking bank account codes such as Mexico's CLABE or Argentina's CBU, validating Brazilian PIX payment keys, normalizing phone numbers, and looking up Brazilian or Costa Rican companies by their registration number, including compliance status for anti money laundering checks. A second group covers money and markets, offering economic indicators like Chile's UF and UTM, Argentina's official and blue dollar exchange rates, Brazil's SELIC and CDI rates, Colombia's legally binding TRM rate, historical rate data, and currency conversion across 18 Latin American currencies. A third group deals with time, including public holidays for 20 countries, upcoming holidays, long weekends, and holiday aware business day counting for things like payroll or delivery schedules. Installing it requires no signup and no API keys. You install a small runner tool called uv, then add a short configuration block to your AI client, such as Claude Desktop or Claude Code, pointing it at this server. After that, you can simply ask your AI assistant a question in plain language, such as whether a specific tax ID is valid, and the assistant picks the right tool automatically. The basic tools described above are free forever. A paid Pro tier, priced at $19.99 a month, adds sanctions and watchlist screening, tax ID based company lookups for more countries, and bulk validation of up to 10,000 IDs at once, delivered as a hosted service rather than something you run yourself. The underlying data comes from free public government and financial APIs, and the tax ID validation itself is done with local math and no external dependencies.
