Real prompts you can type the moment it's connected — no setup, no docs to read.

Use “extract_xml”: Extrahiert die eingebettete XML-Datei aus einem ZUGFeRD/Factur-X PDF.

Use “check_consistency”: Prüft ob die sichtbaren PDF-Daten mit den eingebetteten XML-Daten übereinstimmen.

Security check

How secure is the ZUGFeRD Validator MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how ZUGFeRD Validator holds up.

Verified directory serverZUGFeRD Validator · zugferd-validator.de

Official endpoint

Operated by ZUGFeRD Validator (zugferd-validator.de) at its documented MCP endpoint — not a third-party mirror or community re-host.

No sign-in needed

This server only exposes public data — no account and no credentials are involved when you connect.

Scanned before it goes live

gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.

Watched for drift

If ZUGFeRD Validator adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

FAQ

Questions, answered

Is there an official ZUGFeRD Validator MCP server?

Yes — ZUGFeRD Validator operates its own remote MCP server at api.zugferd-validator.de. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

How do I connect ZUGFeRD Validator to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick ZUGFeRD Validator in the directory. No account or sign-in is needed. From then on, ZUGFeRD Validator's tools are available in every client you've connected to gate.

Do I need to host anything?

No. ZUGFeRD Validator runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the ZUGFeRD Validator MCP server safe to connect?

It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.

Is it free?

Yes — you can get started with gate for free and connect ZUGFeRD Validator in minutes. No credit card required.
