LatAm Data

LatAm Data MCP

An MCP server that gives agents reliable access to LatAm data that is otherwise scattered, undocumented, or Spanish-only: tax-ID validation for 12 countries, live economic indicators, exchange rates (including Argentina's blue rate and Colombia's legally binding TRM), Brazilian company lookups, holidays, and business-day math.

Install (free — runs on your machine)

No signup, no API keys. Two steps:

1. Install `uv` (the runner) if you don't already have it:

brew install uv                              # macOS

or, any platform:

curl -LsSf https://astral.sh/uv/install.sh | sh

2. Add the server to your MCP client config (mcpServers block):

{

"mcpServers": { "latam-data": { "command": "uvx", "args": ["latam-data-mcp"] } } }

• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) — then quit and reopen the app.
• Cursor / Claude Code / other clients: same mcpServers block, in their config.

Then just ask your agent *"Is Chilean RUT 60.910.000-1 valid?"* — done. Requires Python 3.10+ (uv handles it).

macOS gotcha: if the server doesn't show up, use the full path to uvx as

the command (run which uvx → e.g. /opt/homebrew/bin/uvx). GUI apps don't

always inherit your shell's PATH. First launch takes a few seconds while uv

fetches the package; instant after that.

See it work

Once connected, just ask your agent in plain language:

*"Is the Mexican CLABE 646180110400000007 valid, and which bank is it?"*

→ ✅ valid · Banco STP · branch 180 · account …

*"Validate Brazilian CNPJ 00.000.000/0001-91 and tell me who it is."*

→ ✅ Banco do Brasil S.A. · active · Brasília-DF

*"What's the UF and the dollar today in Chile? And convert 2,500,000 CLP to BRL."*

*"How many business days between 2026-09-01 and 2026-09-30 in Chile?"*

→ holiday-aware working-day count (skips Fiestas Patrias)

No glue code — the agent picks the right tool and calls it.

Pro — the compliance & data tier

The tools above are free forever. Pro adds the compliance and data features teams actually pay for — the stuff you can't get from a free public API:

• 🛡️ OFAC sanctions / watchlist screening — fuzzy name matching (catches aliases, reordered names, accents) for KYC/AML onboarding
• 🏢 Company lookup by tax ID — 🇨🇱 Chile today; 🇦🇷 Argentina, 🇵🇪 Peru, 🇲🇽 Mexico coming — name, status, activities, compliance flags
• 📋 Bulk validation — validate up to 10,000 IDs in one call, for onboarding pipelines and CRM cleanups
• *coming:* PEP screening, change-monitoring webhooks, extended historical data

Delivered as a managed, always-on hosted endpoint (no self-hosting), with higher rate limits and priority support.

Develop

python3.11 -m venv .venv

.venv/bin/pip install -e ".[dev]" .venv/bin/python server.py # stdio; set PORT=8000 for Streamable HTTP

Tests

.venv/bin/pytest              # offline suite: validators + MCP protocol layer

.venv/bin/pytest -m live # integration tests against the real upstream APIs

Validators are verified against python-stdnum's reference algorithms and real IDs of public institutions (Banco do Brasil, SUNAT, DIAN, UTE, U. de Chile).

Data sources

All free public APIs, no keys: gael.cloud (Chile), Bluelytics (Argentina), BrasilAPI (Brazil), datos.gov.co (Colombia), open.er-api.com (regional FX), Nager.Date (holidays). Tax-ID validation is pure local math — zero dependencies, zero latency, nothing to break.

Roadmap

• Historical series (UF, USD, TRM)
• Deploy free tier + directory listings (Smithery, PulseMCP, mcp.so)
• Monetization via MCPize (85% rev share) once free tier has weekly active users
• Electronic invoicing requirements per country (static knowledge tool)
