# 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.

## Tools (20)

### Identity, banking & companies

| Tool | What it does |
|---|---|
| `validate_tax_id` | Validates national tax IDs with real check-digit math for **15 countries**: 🇨🇱 RUT, 🇦🇷 CUIT/CUIL, 🇲🇽 RFC, 🇧🇷 CPF/CNPJ (incl. 2026 alphanumeric CNPJs), 🇨🇴 NIT, 🇵🇪 RUC, 🇺🇾 RUT, 🇪🇨 cédula/RUC, 🇵🇾 RUC, 🇻🇪 RIF, 🇬🇹 NIT, 🇩🇴 RNC, 🇵🇦 RUC+DV, 🇨🇷 cédula, 🇧🇴 NIT. Returns canonical formatting and person/company/public-entity detection. |
| `validate_bank_account` | Validates interbank account codes with check-digit math: 🇲🇽 CLABE (18-digit), 🇦🇷 CBU/CVU (22-digit, incl. Mercado Pago virtual accounts). Decodes bank, branch and account — verify a payout destination before sending money. |
| `validate_pix_key` | Validates a 🇧🇷 PIX key (CPF, CNPJ, e-mail, +55 phone, or random UUID) and detects its type — CPF/CNPJ with full check-digit math. |
| `validate_phone_number` | Validates & normalizes phone numbers for 15 countries → E.164, national format, mobile/landline detection. Handles Brazil's 9th digit, Mexico's 10-digit, Argentina's 9/15, Chile's 9-prefix. |
| `brazil_bank_lookup` | Resolves a 🇧🇷 bank by COMPE code (name, ISPB). |
| `brazil_company_lookup` | Full federal-registry data for any Brazilian company by CNPJ: legal name, status, size, main activity, capital, address, partners. |
| `costa_rica_company_lookup` | 🇨🇷 taxpayer by cédula: name, regime, activities, and **compliance status** (moroso/omiso) from Hacienda — for KYC/AML. |

### Money & markets

| Tool | What it does |
|---|---|
| `chile_indicators` | UF, UTM, USD, EUR and more, in CLP. |
| `argentina_exchange_rates` | Official vs **blue** rate for USD/EUR. |

| `colombia_official_trm` | The legally binding USD/COP rate with validity dates. |
| `brazil_historical_series` | Historical SELIC/CDI/IPCA/USD over a date range, with min/max/avg/change — for trend analysis and backtesting. |
| `colombia_trm_history` | Historical USD/COP (TRM) over a date range. |
| `costa_rica_exchange_rate` | 🇨🇷 official USD/EUR colón rate. |

## 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:

```bash
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):

```json
{
  "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

```bash
python3.11 -m venv .venv
.venv/bin/pip install -e ".[dev]"
.venv/bin/python server.py     # stdio; set PORT=8000 for Streamable HTTP
```

## Tests

```bash
.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)
