Eleata E-Invoice MCP - EU E-Invoice Validation for AI Agents

EU e-invoicing mandates are rolling out across member states. Germany requires XRechnung, France mandates Factur-X, and Peppol is the pan-European standard. Eleata E-Invoice MCP gives AI agents the ability to validate invoices against all major EU formats - without manual checking.

Why This Matters for Operators

• Regulatory risk: Invalid e-invoices = rejected payments, compliance fines, audit flags
• Multi-format complexity: Each EU country has its own format (XRechnung, Factur-X, UBL/CII, Peppol BIS)
• AI agent automation: Let AI validate invoices before submission instead of manual human review
• Error explanation: Validation errors come with human-readable explanations, not just codes

Quick Start

# Add to Hermes
hermes mcp add eleata-einvoice -- npx -y @eleata/eleata-einvoice-mcp

# Or via GitHub
git clone https://github.com/hernaninverso/eleata-einvoice-mcp
cd eleata-einvoice-mcp
npm install

Supported Formats

Format	Jurisdiction	Status
Peppol BIS Billing 3.0	EU-wide (cross-border)	Mandatory
XRechnung 3.0	Germany	Mandatory for B2G, expanding to B2B
Factur-X 1.0	France	Mandatory (2024-2026 phased)
UBL 2.1	Netherlands, Belgium, Nordics	Widely adopted
CII (Cross-Industry Invoice)	EU standard	UN/CEFACT based

Usage Patterns

Validate an Invoice

# Validate a Peppol BIS invoice
result = mcp_eleata_einvoice(
    action="validate",
    params={
        "invoice_xml": "<Invoice>...</Invoice>",
        "format": "peppol-bis-3.0"
    }
)
# Returns: {valid: true/false, errors: [...], warnings: [...]}

Batch Validation for Accounting Systems

# In your accounting workflow, validate every outgoing invoice
invoices = get_pending_invoices()

for invoice in invoices:
    validation = mcp_eleata_einvoice(
        action="validate",
        params={
            "invoice_xml": invoice.xml,
            "format": invoice.required_format  # Auto-detected from customer country
        }
    )
    if not validation.valid:
        # AI agent explains errors and suggests fixes
        fix_suggestions = mcp_eleata_einvoice(
            action="explain_errors",
            params={"error_codes": validation.errors}
        )
        log_and_flag_for_review(invoice.id, fix_suggestions)

Cross-Border Compliance Check

# Before sending to a German customer, validate against XRechnung
# Before sending to a French customer, validate against Factur-X
customer_country = get_customer_country(customer_id)
format_map = {"DE": "xrechnung-3.0", "FR": "factur-x-1.0", "EU": "peppol-bis-3.0"}

validation = mcp_eleata_einvoice(
    action="validate",
    params={
        "invoice_xml": invoice_xml,
        "format": format_map.get(customer_country, "ubl-2.1")
    }
)

Operator Playbook: Automated Compliance Pipeline

1. Pre-submission validation: AI validates every invoice before sending to customer/government portal
2. Format auto-detection: AI routes to correct format based on customer country (DE→XRechnung, FR→Factur-X)
3. Error remediation: AI explains what's wrong and suggests XML fixes
4. Batch auditing: Run nightly validation on all invoices in your accounting system
5. Compliance reporting: Generate audit-ready reports showing 100% validation pass rate

Complementary Tools

Tool	Purpose
CorpusIQ QuickBooks MCP	Pull invoices from QuickBooks for validation
AIR Blackbox MCP	EU AI Act compliance (companion regulatory check)
Customs MCP	HS codes and duty rates for cross-border shipments
botcorpus	CZ/SK/AT/EU legal facts for jurisdictional context

Business Impact

• Reduce rejected invoices: 100% pre-submission validation eliminates format-related rejections
• Compliance automation: No manual XML checking across 27 EU member states
• Audit readiness: Every validation logged, timestamped, and reportable
• Multi-country scaling: Add new EU markets without hiring compliance specialists

Integration with CorpusIQ

CorpusIQ is the connector layer that lets AI assistants read the systems a business already runs on - accounting, payments, CRM, email, files and analytics - and answer with the source named. It is read-only by design: it retrieves data and never writes to, or acts in, a connected system, which is what makes it safe to point at live accounts.

This page is part of the CorpusIQ directory, the reference we maintain for the MCP server and agent-skill ecosystem. Run alongside CorpusIQ, a third-party server like this one can be combined with a company's own business data in a single answer.
