MCP Europe Business Suite

Overview

European business compliance suite for AI agents — 28 tools built for backends, fintechs, e-commerce, ERPs, and accounting platforms operating across the EU and UK.

Stop hardcoding tax IDs, IBAN checksums, VAT rules, and holiday calendars in your agents. This server delivers offline, low-latency validation and business logic for 8 countries with native tools (PT, ES, FR, DE, IT, UK, NL, BE) plus 18+ countries via VAT rates and IBAN coverage (PL, SE, DK, FI, AT, IE, GR, HU, RO, CZ, HR + others).

All tools are read-only, deterministic, and require no external auth. Designed to plug directly into Claude Desktop, custom agents, and any MCP-compatible client.

Use cases

• E-commerce checkout — Apply correct country VAT (with OSS distance-selling threshold logic) and validate customer tax IDs before invoicing.
• B2B invoicing — Validate intra-EU customer VAT numbers, suggest reverse charge treatment, generate invoices with mandatory fields per country.
• Fintech onboarding — Verify tax IDs and IBAN in real time during KYC/KYB flows for EU/UK customers.
• E-invoicing readiness — Check upcoming mandates: Belgium B2B (Jan 2026), France B2B (Sep 2026), Poland KSeF (Feb 2026), Germany B2B receive (2025) / send (2027).
• Accounting automation — Calculate working days for payment terms (PT 30d, FR 60d, DE auto-interest), schedule salary or invoice payments avoiding holidays.
• AI agents handling EU customers — Drop-in compliance layer for any LLM-based system that touches European invoices, payments, or tax IDs.

Notes on use

This server provides deterministic algorithmic validation (checksums, format checks, holiday calendars) and reference data (VAT rates, payment terms, e-invoicing rules) as a first-line compliance layer for AI agents and automated workflows.

It is designed to catch errors before they reach production systems — invalid tax IDs, incorrect VAT rates, missing invoice fields, scheduling on non-working days.

The data is updated periodically and reflects published regulations at the time of release. For final legal certification of invoices, complex tax situations (cross-border edge cases, sector-specific rules, recent regulatory changes), or audit-grade compliance, consult a tax professional or your local tax authority's official systems (e.g. AT Portal, Agencia Tributaria, Agenzia delle Entrate, HMRC).
