# 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. | | `brazil_market_rates` | SELIC, CDI, IPCA. | | `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. | | `currency_convert` | Convert any amount between two currencies at the live rate. | | `latam_exchange_rates` | All 18 LatAm currencies vs USD in one call. | ### Time & calendars | Tool | What it does | |---|---| | `public_holidays` | Official holidays for 20 LatAm countries, any year. | | `next_holidays` | Upcoming holidays from today. | | `long_weekends` | Long weekends with bridge-day analysis. | | `business_days` | Working-day count between dates, holiday-aware — for SLA, payroll, logistics, settlement 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: ```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. ### 💳 $19.99/mo — [→ Subscribe to Pro](https://latam-data-mcp.lemonsqueezy.com/checkout/buy/f75c3532-a919-4cab-a121-a9278066fe4e) **Building for a team, or need a specific country/data source first?** [Open an issue](https://github.com/svkbogislav/latam-data-mcp/issues/new) — tell me your use case and I'll get you early access. ## 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)
