Overview

AI-generated overview

Generates German XRechnung 3.0 e-invoices from JSON, pre-checks e-invoice XML, and extracts invoice data from XML or ZUGFeRD PDFs.

What you can do
  • Generate a German XRechnung 3.0 e-invoice (UBL 2.1, EN 16931) from plain JSON, with totals, VAT and rounding computed server-side
  • Validate an XRechnung UBL or CII XML file against priority EN 16931 / XRechnung rules, with cent-exact total recalculation and findings carrying official rule IDs
  • Extract structured JSON (parties, lines, totals, payment data) from XRechnung UBL/CII XML or a ZUGFeRD/Factur-X PDF
When to use it
Useful when an assistant has to produce German public-sector e-invoices, sanity-check an invoice file before official submission, or pull structured data out of received e-invoices and ZUGFeRD PDFs.
Requirements
Remote hosted endpoint, no local install. Validation and extraction require an API key; generation is described without a stated key requirement. No environment variables or headers are declared in the manifest.
Before you install
The service is paid: validation costs 10 credits and extraction 5 credits per call, so usage spends money. The validation tool is a pre-check, not the official KoSIT validation. Invoice contents, including party and payment data, are sent to a third-party server.

Installation

In SourceWeft

  1. Open Dropcoin Invoice in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.freshfos%2Fdropcoin-invoice/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
