Argentina's official public data (INDEC, BCRA, 38 portals): search, read tables, cited answers.
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。
Authorization标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。
你需要
你用的是哪个应用?
在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。
这个地址需要在请求的 header 中放入密钥,而添加连接器的菜单无法设置。请改用 Claude Code、Cursor 或 VS Code。
在终端中运行这条命令
claude mcp add --transport http datos-publicos https://mcp.openarg.org/mcp --header 'Authorization: your-value'运行前请先填写空着的值。
粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json
{
"mcpServers": {
"datos-publicos": {
"url": "https://mcp.openarg.org/mcp",
"headers": {
"Authorization": "your-value"
}
}
}
}浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。
粘贴到项目中的 .vscode/mcp.json

它在 1 项适用的基础检查中通过了 1 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。
你需要填写:Authorization
它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。
GitHub 仓库最后更新于–,最新版本(1.0.0)于38天前进入注册中心。
支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

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.
https://mcp.openarg.org/mcp (Streamable HTTP)Authorization: Bearer oarg_sk_…. Free key at openarg.org/desarrolladoresClaude 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 OPENARG_API_KEY and tell your assistant:
Add the OpenArg MCP server following https://mcp.openarg.org/llms.txt. My key is in OPENARG_API_KEY. Test the connection with listar_fuentes.
All tools are read-only. Tool names and outputs are in Spanish; ask in any language.
| Tool | Mode | What it does |
|---|---|---|
buscar_datasets | data | Search the catalog: title, portal, official link and queryable tables |
describir_tabla | data | Columns and types, row count, period covered, 5-row sample |
obtener_datos | data | Rows as CSV (up to 500): pick columns, date range and equality filters. No SQL |
listar_fuentes | data | Portals covered and dataset count per portal |
consultar_datos_publicos | answers | A natural-language question answered by OpenArg, with sources and warnings |
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.
| Per key | |
|---|---|
| Data mode | 200 requests/month, 30/min, up to 500 rows per request |
| Answers mode | 10 questions/month, 2/min |
| Founders | 2,000 requests and 100 questions per month |
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.
This is the code of the server behind mcp.openarg.org:
mcp_publico/core.py: pure logic, standard library only.mcp_publico/server.py: MCP SDK and HTTP routes.mcp_publico/site/: the website.The server is stateless and makes no decisions about quotas or authentication. It forwards the user's key to the OpenArg API, which validates it, applies the quota and answers. Running it yourself only makes sense next to an OpenArg backend (BACKEND_URL). To just *use* the data, connect to the hosted endpoint above.
It is developed in colossus-lab/openarg_backend (mcp_publico/) and mirrored here.
OpenArg MCP conecta tu asistente de IA a más de 33.000 datasets públicos oficiales de Argentina, de 38 portales: el INDEC (censos, EPH, pobreza, PIB, IPC), el BCRA, ministerios, provincias, municipios y el Congreso. Cada dato viene con su fuente oficial.
https://mcp.openarg.org/mcp con el header Authorization: Bearer oarg_sk_…. Hay guías para cada cliente en mcp.openarg.org/empezar.html.Hay dos modos. El modo datos permite 200 pedidos por mes: tu asistente busca y lee las tablas. El modo respuestas permite 10 preguntas por mes: OpenArg arma la respuesta y verifica los números.
