Overview

Description from the maker (original English)

Registro Mercantil español (BORME) + subvenciones (BDNS) + contratos públicos (PLACSP), por empresa.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Other
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http asientouno https://mcp.asientouno.com/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "asientouno": {
      "url": "https://mcp.asientouno.com/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "asientouno": {
      "type": "http",
      "url": "https://mcp.asientouno.com/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret required HTTP header
    Bearer — clave gratuita en https://asientouno.com/contacto

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Asientouno safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 43 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, MyGroceryPal

Asiento Uno — servidor MCP del Registro Mercantil español

Datos del BORME (Boletín Oficial del Registro Mercantil) cruzados con subvenciones públicas (BDNS) y contratos públicos (PLACSP), por empresa, con enlace al documento oficial de cada dato. Pensado para agentes de IA: diligencia debida, KYB, verificación de proveedores y clientes.

  • Endpoint remoto: https://mcp.asientouno.com/mcp (Streamable HTTP, JSON-RPC)
  • Autenticación: Authorization: Bearer
  • Plan gratuito: 50 llamadas al día (Pro: 500, Business: 5.000), 60 por minuto
  • Web: https://asientouno.com/mcp · Precios: https://asientouno.com/precios

English: MCP server for the Spanish Companies Registry gazette (BORME),

joined with public grants (BDNS) and public procurement awards (PLACSP) per

company. Every fact links to its official publication. Remote Streamable

HTTP endpoint, Bearer API key, free tier (50 calls/day), self-serve signup.

Herramientas

HerramientaQué devuelve
asientouno_buscar_empresaNombre o NIF → empresas coincidentes (con desambiguación: dice cuándo no está segura).
asientouno_informe_completoIdentificativos, órgano de administración vigente, actos recientes y señales de riesgo (concurso, disolución, extinción).
asientouno_actos_bormeActos societarios paginados por cursor, cada uno con la URL oficial de su publicación en el BORME.
asientouno_cargos_personaNombre de persona → cargos vigentes e históricos y empresas vinculadas (el grafo de relaciones).
asientouno_subvenciones_empresaSubvenciones registradas en la BDNS para la empresa.
asientouno_contratos_empresaAdjudicaciones en la PLACSP para la empresa.
asientouno_riesgo_empresaConcurso, disolución y extinción publicados en el BORME, con fecha y documento.
asientouno_cuentas_anualesResponde no_disponible_aun cuando no hay dato: nunca inventa una cifra.

Todas las herramientas son de solo lectura (readOnlyHint: true).

Conseguir una API key

En https://asientouno.com/cuenta: entras con tu correo (enlace mágico, sin contraseña) y pulsas «Crear mi API key gratuita». La clave aparece en pantalla una sola vez. Sin tarjeta. Los planes Pro y Business se contratan en https://asientouno.com/precios y suben la cuota de esa misma clave.

Conectar

Claude Desktop / Claude Code (vía mcp-remote)

examples/claude_desktop_config.json:

{

"mcpServers": { "asientouno": { "command": "npx", "args": [ "-y", "mcp-remote", "https://mcp.asientouno.com/mcp", "--header", "Authorization: Bearer ${ASIENTOUNO_API_KEY}" ], "env": { "ASIENTOUNO_API_KEY": "tu_api_key" } } } }

Cualquier cliente MCP con transporte HTTP
curl -s https://mcp.asientouno.com/mcp \

-H "Authorization: Bearer $ASIENTOUNO_API_KEY" \ -H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Sin clave, el servidor responde 401 con el mensaje exacto de lo que falta. https://mcp.asientouno.com/health es público y devuelve {"estado":"ok"}.

Cifras (26/09/2026)

  • 883.659 sociedades y 3,9 millones de actos del BORME (boletines desde el 11/03/2024).
  • 148.339 concesiones de la BDNS (desde 2022), 66.546 atribuidas a 24.051 sociedades.
  • 653.078 adjudicaciones de la PLACSP (desde 2004).

Lo que este servidor NO hace

  • No da cuentas anuales ni cifras de facturación: asientouno_cuentas_anuales responde no_disponible_aun.
  • No dice si una empresa está sancionada: una coincidencia por nombre con una lista no es una sanción.
  • No cubre el BORME anterior a marzo de 2024 ni empresas fuera de España.
  • No tiene SLA: es un servicio en un servidor único; /health es público para que lo vigiles.
  • El saludo del protocolo (initialize, tools/list) responde sin clave; los datos (tools/call) no.

Fuentes y límites, dichos claros

  • BORME cargado desde marzo de 2024; BDNS desde 2022; PLACSP desde 2004.
  • Una coincidencia por nombre no es una identificación: la búsqueda devuelve candidatos y siguiente_paso cuando hay ambigüedad.
  • Nunca se afirma que una empresa esté sancionada por una coincidencia de nombre.
  • Plan gratuito: los nombres de personas físicas van parcialmente ocultos (en los campos y en el texto de los actos) y asientouno_cargos_persona solo busca sociedades. Pro y Business los muestran completos. El nombre de una sociedad es público y se ve siempre.
