ClaudeClaude CodeCursorVS CodeChatGPT

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

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "verifactu": {
      "command": "uvx",
      "args": [
        "verifactu-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add verifactu -- uvx verifactu-mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {

      "command": "uvx",
      "args": [
        "verifactu-mcp"

Common questions

Is Verifactu MCP 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

verifactu-mcp

Servidor MCP para integrar VeriFactu (AEAT) con Claude Code y Cursor.

Permite generar, encadenar y enviar registros de facturación electrónica desde lenguaje natural, sin necesidad de leer la documentación técnica de la AEAT.

Herramientas disponibles

Herramienta	Descripción
`generate_invoice_xml`	Genera XML válido con hash SHA-256 encadenado (sin enviar)
`send_invoice`	Envía registro de alta a la AEAT via API y persiste la huella
`cancel_invoice`	Envía registro de anulación
`check_invoice_status`	Consulta el estado de un registro
`list_invoices`	Lista los registros enviados (filtros opcionales por emisor y paginación)
`get_last_hash`	Devuelve la última huella registrada localmente para un emisor
`calculate_hash`	Calcula el hash SHA-256 de cualquier registro

El encadenamiento real lo gestiona la API verifactuapi.es internamente (vía previous_id). El servidor MCP persiste la huella canónica que devuelve la API en SQLite local (~/.verifactu-mcp/state.db) como audit log, no como mecanismo de encadenamiento operativo. La herramienta get_last_hash consulta ese log.

calculate_hash y la huella huella_local_estimada de send_invoice son estimaciones heurísticas para inspección — la huella canónica AEAT incluye el timestamp server-side y solo el servidor puede generarla.

Smoke test contra sandbox

$env:VERIFACTU_API_TOKEN = "<tu_token_sandbox>"

python smoke_test.py [nif_receptor]

Ejecuta list_invoices + send_invoice (¡emite registro real en sandbox!) + check_invoice_status + get_last_hash. NO ejecutar contra producción.

Instalación

# 1. Clona el repositorio

git clone https://github.com/tuusuario/verifactu-mcp cd verifactu-mcp

2. Instala las dependencias

pip install -e .

Configuración en Claude Code

Tras pip install -e ., el script verifactu-mcp queda disponible globalmente. Añade esto a tu ~/.claude.json (o claude_desktop_config.json):

"mcpServers": { "verifactu": { "command": "verifactu-mcp", "env": { "VERIFACTU_API_TOKEN": "tu_token_aqui" } } } }

Alternativa sin script instalado (vía python -m):

"mcpServers": { "verifactu": { "command": "python", "args": ["-m", "verifactu_mcp.server"], "cwd": "/ruta/a/verifactu-mcp", "env": { "VERIFACTU_API_TOKEN": "tu_token_aqui" } } } }

Uso desde Claude Code
