Overview

AI-generated overview

Provides free, no-authentication tools for Spanish administrative data: IBAN validation, EU VAT checks via VIES, Modelo 303 sums, and Veri*factu dates.

What it does
This remote MCP server exposes a small set of Spanish-focused validation and calculation tools. According to its description, these cover IBAN validation, EU VAT number checking through VIES, Modelo 303 tax form sums, and Veri*factu date handling. No individual tool names or parameters are listed in the manifest, so the exact inputs and outputs are not documented here.
When to use it
Worth adding when an assistant needs to check Spanish or EU banking and tax identifiers, total up Modelo 303 figures, or work with Veri*factu dates during Spanish accounting or invoicing tasks. It is not a general-purpose finance or accounting suite.
Requirements
A remote streamable HTTP endpoint at the provider's API host; no packages, environment variables, headers, or authentication are declared. Network access to that endpoint is required.
Before you install
The manifest declares no authentication and no credentials, so no secrets are requested. VAT checks are sent to VIES, a third-party EU service, so identifiers leave the local environment. Validation and calculation results should be confirmed before being used for tax or invoicing decisions.
