MCP server giving AI agents reliable access to Latin American data: tax-ID validation, indicators, FX, company lookups, holidays

LatAm Data MCP

The Latin American data layer your AI agent is missing.

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 download or clone needed. Add this to your MCP client config — uvx fetches and runs the server straight from this repo:

Claude Desktop / Cursor / Claude Code (mcpServers block):

{
  "mcpServers": {
    "latam-data": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/svkbogislav/latam-data-mcp", "latam-data-mcp"]
    }
  }
}

Or install it as a command:

uvx --from git+https://github.com/svkbogislav/latam-data-mcp latam-data-mcp
# or:  pipx install git+https://github.com/svkbogislav/latam-data-mcp

Requires Python 3.10+. No API keys — every data source is free and public.

Hosted (managed) endpoint

A always-on hosted instance is available at https://latam-data.fastmcp.app/mcp (Streamable HTTP, authenticated). Use this if you'd rather not run anything locally.

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)
