claude mcp add --transport http invoiceforge https://invoiceforge.agenttoolworks.com/mcpWhat InvoiceForge does
InvoiceForge runs as a hosted endpoint without local software dependencies. It provides agents with four tools: generate_invoice, validate_invoice, extract_invoice, and describe_coverage. The server validates compliance, outputs electronic invoices, and parses incoming documents under the EN 16931 and Peppol BIS Billing 3.0 standards. It handles both UBL and CII formats.
Usage is billed per call from prepaid credits. Primary generation and validation calls cost 1 credit ($0.01 at Starter rates), while describe_coverage costs 0.2 credits. Registration includes 100 free credits with no card required. InvoiceForge checks validation rules and outputs XML, but it does not transmit documents anywhere. It is not an accredited electronic invoicing network platform.

- generate electronic invoices conforming to EN 16931 standards
- validate Peppol BIS Billing 3.0 structures in UBL and CII formats
