OpenArg — Argentina public data tools (5)

write = sends, deletes, buys or posts

buscar_datasetsFree
Busca en el catálogo de OpenArg (más de 30.000 datasets de portales oficiales). Devuelve título, portal, descripción, link a la fuente oficial y las tablas consultables de cada dataset (usalas con `describir_tabla` y `obtener_datos`). `texto` es lo que buscás, en castellano ("tasas de interés BCRA", "matrícula escolar CABA"). `portal` filtra por portal (ver `listar_fuentes`). `limite` entre 1 y 25. No descuenta preguntas.
consultar_datos_publicosFree
Responde una pregunta sobre datos públicos oficiales de Argentina, con fuentes. Ejemplos: "¿Cuál fue la tasa de desempleo del último trimestre?", "Evolución del IPC en 2025", "¿Cuántos diputados tiene cada bloque?", "Presupuesto ejecutado por el Ministerio de Salud en 2024". La respuesta incluye los datasets usados (con link al portal oficial), advertencias sobre la calidad o cobertura del dato, y cuántas preguntas le quedan este mes al usuario. Descuenta 1 de sus preguntas del mes (10 gratis): si podés responder con `buscar_datasets` + `obtener_datos`, preferí esas.
describir_tablaFree
Muestra las columnas (con su tipo), cantidad de filas, período cubierto y una muestra de una tabla. `tabla` es el nombre que devuelve `buscar_datasets`. Usalo antes de `obtener_datos` para saber qué columnas pedir y qué fechas existen. No descuenta preguntas.
listar_fuentesFree
Lista los portales de datos abiertos que cubre OpenArg y cuántos datasets tiene cada uno. No descuenta preguntas: cuenta como un pedido del modo datos.
obtener_datosFree
Trae filas de una tabla, en CSV, con la fuente oficial. - `columnas`: las que quieras (por defecto, todas); nombres exactos de `describir_tabla`. - `desde` / `hasta`: período, como AAAA, AAAA-MM o AAAA-MM-DD, sobre la columna de fecha. - `filtros`: igualdad exacta por columna, p. ej. {"provincia": "Córdoba"} (hasta 5). - `orden`: "asc" o "desc" por fecha. `limite`: 1 a 500 filas. No descuenta preguntas.

OpenArg MCP — Argentina's public data, in your AI assistant

mcp.openarg.org · Español ↓

A remote Model Context Protocol server that connects Claude, Cursor, VS Code or your own agent to 33,000+ official Argentine public datasets from 38 government portals: INDEC (census, household survey, poverty, GDP, CPI), the Central Bank (BCRA), national ministries, provinces, municipalities and Congress.

Every answer comes with its source: the dataset title, the portal and a link to the official file.

Endpoint: https://mcp.openarg.org/mcp (Streamable HTTP)
Auth: Authorization: Bearer oargsk…. Free key at openarg.org/desarrolladores
Cost: free

Quick start

Claude Code

claude mcp add --transport http openarg https://mcp.openarg.org/mcp \
  --header "Authorization: Bearer oarg_sk_YOUR_KEY"

Cursor (~/.cursor/mcp.json) and other clients with mcpServers

{
  "mcpServers": {
    "openarg": {
      "url": "https://mcp.openarg.org/mcp",
      "headers": { "Authorization": "Bearer oarg_sk_YOUR_KEY" }
    }
  }
}

Claude Desktop (through mcp-remote)

{
  "mcpServers": {
    "openarg": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.openarg.org/mcp",
               "--header", "Authorization:${OPENARG_AUTH}"],
      "env": { "OPENARG_AUTH": "Bearer oarg_sk_YOUR_KEY" }
    }
  }
}

VS Code (.vscode/mcp.json). The key is asked once and stored encrypted.

{
  "inputs": [{ "type": "promptString", "id": "openarg-key", "description": "OpenArg key", "password": true }],
  "servers": {
    "openarg": {
      "type": "http",
      "url": "https://mcp.openarg.org/mcp",
      "headers": { "Authorization": "Bearer ${input:openarg-key}" }
    }
  }
}

Your own agent. Put the key in OPENARGAPIKEY and tell your assistant:

Add the OpenArg MCP server following https://mcp.openarg.org/llms.txt. My key is in OPENARGAPIKEY. Test the connection with listar_fuentes.

Tools

All tools are read-only. Tool names and outputs are in Spanish; ask in any language.

Data mode. Your assistant does the reasoning over the rows. It is fast (about 1 s) and allows 200 requests per month.

Answers mode. OpenArg picks the tables, cross-references them and checks the numbers against the source. It allows 10 questions per month.

Limits

Quotas reset on the 1st of each month at 00:00 UTC. Once the monthly quota runs out, the server uses the key's credits if it has any; otherwise it answers HTTP 402 with the reset date. Founders are people who support OpenArg through colossuslab.org/support. If you need more for journalism, research or an NGO and can't contribute, write to devops@colossuslab.org. The full table is at mcp.openarg.org/limites.html. OpenArg reflects what each agency publishes. The answers mode uses a language model and can be wrong, so check the linked source before publishing a figure.
