Category Data and Analytics
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability60
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1997 tokens (~332/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- Manipulation not yet verified: only 2 of 7 captured unit(s) of tool text has been judged so far, so we will not certify text no model has read as clean.Unverified
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

agregar_datos Calcular totales y rankings sobre una tabla de OpenArg ~506
Calcula en la base una suma, promedio, conteo, mínimo o máximo, opcionalmente agrupado. Usala SIEMPRE que necesites un total, un promedio, un conteo, un mínimo/máximo o un ranking, en vez de traer filas con `obtener_datos` y hacer la cuenta vos: es exacta, no tiene el tope de 500 filas y gasta muchos menos tokens. - `operacion`: "suma", "promedio", "conteo", "minimo" o "maximo". - `columna`: la que se suma/promedia/etc. (nombres exactos de `describir_tabla`); no va con "conteo", que cuenta filas (si la mandás, da error). Las columnas de texto con números se leen según su formato (1.234,5 o 1,234.5); si el formato es ambiguo, no calcula y lo dice. - `agrupar_por`: hasta 3 columnas, p. ej. ["jurisdiccion_desc"] para un ranking. - `filtros`, `desde`, `hasta`, `columna_fecha`: como en `obtener_datos` (hasta 6 filtros). - `ordenar_por`: "valor" (por defecto, para rankings) o una columna de `agrupar_por` (p. ej. el año, para una serie). `orden`: "desc" (por defecto) o "asc". - `limite`: grupos a devolver, 1 a 200. - `ponderar_por`: la columna de ponderación de una encuesta (con "conteo" da la población estimada, no la cantidad de filas de la muestra). La respuesta dice sobre cuántas filas se calculó (`filas_usadas`, de todos los grupos) y si hay más grupos que `limite`. Si ninguna fila cumple los filtros no hay valor: dice qué valores existen. No descuenta preguntas.

buscar_datasets Buscar datasets públicos de Argentina ~149
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_publicos Consultar datos públicos de Argentina ~190
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. Cada respuesta descuenta 1 de sus preguntas del mes (10 gratis); un error, un corte por tiempo o la misma pregunta repetida dentro de los 5 minutos no descuentan. Si podés responder con `buscar_datasets` + `obtener_datos` o `agregar_datos`, preferí esas.

describir_tabla Describir una tabla de OpenArg ~173
Muestra las columnas (con su tipo), cantidad de filas, período cubierto, frescura y una muestra de una tabla. `tabla` es el nombre que devuelve `buscar_datasets`. Usalo antes de `obtener_datos` o `agregar_datos` para saber qué columnas pedir y qué fechas existen. La frescura dice cuándo leyó OpenArg la tabla de su fuente, cuál es el último dato y, sólo si la tabla es una foto del período en curso, su fecha de corte. La fecha de lectura no es la de los datos: una tabla de un período pasado o sin columna de fecha no es vigente por haberse leído hoy. No presentes como actual un dato viejo. No descuenta preguntas.

obtener_datos Obtener datos de una tabla de OpenArg ~457
Trae filas de una tabla, en CSV, con la fuente oficial. Para un total, promedio, conteo, mínimo, máximo o ranking NO traigas filas para sumarlas: usá `agregar_datos`. - `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 (o de año). - `filtros`: hasta 5. Igualdad: {"provincia": "Córdoba"}. Con operador, una lista: [{"columna": "monto", "operador": "mayor_que", "valor": "1000000"}, {"columna": "provincia", "operador": "en", "valores": ["Salta", "Jujuy"]}]. Operadores: =, !=, mayor_que, menor_que, >=, <=, contiene y en. La igualdad y `contiene` no distinguen mayúsculas ni acentos (en tablas de más de un millón de filas, sí: ahí la respuesta dice en `filtros_aplicados` qué se buscó tal cual). - `orden`: "asc" (por defecto: primero lo más viejo) o "desc" (primero lo más reciente), por fecha. Para el último dato de una serie, pedí "desc". - `limite`: 1 a 500 filas. Si hay más, la respuesta lo dice y da el `offset` de la página siguiente (hasta 10.000). - `columna_fecha`: opcional, otra columna de fecha para `desde`/`hasta` y el orden. Si ninguna fila cumple los filtros, la respuesta dice qué valores existen. No descuenta preguntas.

What is the OpenArg — Argentina public data MCP server?
OpenArg — Argentina public data is an MCP server listed in the public MCP registry as org.openarg/datos-publicos. Argentina's official public data (INDEC, BCRA, 38 portals): search, read tables, cited answers. This page covers its hosted endpoint (https://mcp.openarg.org/mcp).
Is the OpenArg — Argentina public data MCP server safe to use?
OpenArg — Argentina public data scores 81 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the OpenArg — Argentina public data MCP server expose?
OpenArg — Argentina public data exposes 6 tools: consultar_datos_publicos, listar_fuentes, buscar_datasets, describir_tabla, obtener_datos, agregar_datos. Their descriptions and schemas cost roughly 1,518 tokens of context every time the server is loaded.
Does the OpenArg — Argentina public data MCP server require authentication?
No. We connected to OpenArg — Argentina public data without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the OpenArg — Argentina public data MCP server still maintained?
OpenArg — Argentina public data is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What did VerifyMCP test on the OpenArg — Argentina public data MCP server?
VerifyMCP ran 12 checks on OpenArg — Argentina public data, covering TLS certificate, Authorization, HTTPS, HSTS header and 8 more. One item could not be completed, a gap on our side rather than a finding about OpenArg — Argentina public data: Judged manipulation. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
