Invapi Mcp
Connects Claude to the Invapi E-Invoicing API for working with European invoice formats. You get conversion between UBL, CII, ZUGFeRD, Excel, and JSON, plus validation against XRechnung 3.0.2 standards. The extraction tools pull structured data from PDF invoices and images, including QR codes. There's also a batch operation that handles up to 100 conversions in one request. Reach for this when you're building accounting workflows, need to parse supplier invoices at scale, or have to output compliant XML for German or EU tax systems. Requires an API key from invapi.org, which operates on a credit system.
