Overview

AI-generated overview

Remote MCP server that lets an assistant detect, parse, validate, fix and render European e-invoices such as XRechnung, ZUGFeRD, Factur-X, Peppol BIS 3.0 and…

What you can do
  • Detect the format, syntax, profile and country standard of an e-invoice file, and list supported formats, rule sets and costs
  • Parse invoices into normalised JSON with parties, lines, VAT breakdown, totals and payment details
  • Validate against official rule sets (KoSIT, OpenPeppol, KSeF, Croatian, Spanish, Malaysian) and report each failed rule with id, severity and XPath
  • Fix common EN 16931 validation errors deterministically, optionally recalculating totals and VAT from the lines
  • Render a readable A4 HTML document or a PDF (returned as base64) in several languages
  • Check the plan, monthly quota, usage and subscription state of the connected API key
When to use it
Useful when you work with European e-invoicing and want an assistant to check whether an invoice file is compliant, extract its contents as structured data, repair typical validation errors, or produce a human-readable HTML or PDF version.
Requirements
A remote Streamable HTTP endpoint; no local install. An optional API key is sent in the Authorization header as a Bearer token; a free key gives 100 requests per month, and without one an anonymous per-IP rate limit applies. Invoice files up to 10 MB are accepted as text or base64.
Before you install
The API key is a secret passed in the Authorization header. Requests are metered: a free tier of 100 requests per month, paid plans, and PDF rendering counts as 2 requests. Invoice content is sent to a third-party service, which states it is processed in memory and discarded. Fixing an invoice changes data, so review the output before relying on it.

Installation

In SourceWeft

  1. Open E-Invoice Checker 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/com.einvoicechecker%2Feinvoice/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

Other MCP clients

Add this to your client's mcpServers config.
