Structured AI-agent access to Uruguay's open government data Acceso estructurado de agentes de IA a los datos abiertos del Estado uruguayo

🌎 Español · English

An MCP server that gives AI agents structured access to Uruguay's open government data — the national data catalog, the Central Bank, the statistics institute, Montevideo's city data & realtime transport, spatial data (IDE), education, health, social programs, government social-security statistics (BPS), tax reference values (DGI), news, and the gub.uy service catalog — behind a single meta-discovery layer.

✨ Why a meta-discovery layer?

Instead of flooding the model with hundreds of tool definitions, the server exposes five meta-tools. The model searches for what it needs, then invokes the matching data tool by name. The prompt-visible surface stays constant no matter how many data sources are added.

Every tool returns a unified envelope: { "_meta": { source, cached, lang, timestamp }, "data": ... }.

At a glance: 5 meta-tools + 84 data tools across 17 modules, plus 54 prompts and 36 resources.

📚 Data sources (modules)

The transport surface of montevideo needs OAuth2 credentials (URUGUAY_MCP_MVD_CLIENT_ID / URUGUAY_MCP_MVD_CLIENT_SECRET); without them the transport tools return a typed validation_error while the CKAN tools work unauthenticated.

🧩 Prompts & Resources

Each module also registers reusable prompts (parameterized Spanish instruction templates) and resources (static reference docs under the uru://<module>/<path> URI scheme), exposed natively through FastMCP.

• 54 prompts — e.g. bcu_cotizacion_dolar_hoy, catalogo_buscar_por_tema, bps_pasividades_actuales, dgi_valor_referencia, ine_buscar_estudios, montevideo_proximo_bus, datastore_unir_dos_fuentes, acce_analizar_compra, impo_consultar_norma, inumet_clima_actual, ide_consultar_catastro, salud_consultar_medicamentos, noticias_ultimas.

• 36 resources — e.g. uru://bcu/codigos-moneda, uru://bps/catalogo-indicadores, uru://dgi/catalogo-valores, uru://catalogodatos/guia-de-uso, uru://montevideo/credenciales-transporte, uru://acce/glosario-ocds, uru://impo/esquema, uru://inumet/variables, uru://ide/capas-destacadas, uru://salud/fuentes, uru://mides/guia-recursos.

See EXAMPLES.md for end-to-end usage scenarios, including cross-source ones via plan_query / execute_batch and SQL JOINs through the datastore module.

🚀 Quick start

# Run directly from PyPI (once published)
uvx uruguay-mcp

# …or install it
pip install uruguay-mcp        # or: uv pip install uruguay-mcp
uruguay-mcp

One-command install into Claude

uruguay-mcp install

Merges the server into Claude Desktop's config (preserving existing mcpServers and unrelated keys) and prints a ready-to-paste snippet for Claude Code / Cursor. Restart the client afterwards.

Claude Desktop config (manual)

{
  "mcpServers": {
    "uruguay-mcp": { "command": "uruguay-mcp" }
  }
}

Each module package is independent (constants · schemas · client · tools · optional prompts/resources). Importing the package self-registers everything it offers.
