What your AI can do with InvoiceForge
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “generate_invoice”: Turns invoice data into a compliant UBL 2.1 XML document following the EN 16931 semantic model, with totals and the VAT breakdown computed f.”
“Use “validate_invoice”: Checks invoice data against a documented subset of the EN 16931 business rules: mandatory fields, code lists, VAT category consistency and t.”
“Use “extract_invoice”: Reads an incoming UBL or CII (Factur-X) invoice XML and returns the data as structured JSON, listing any field the document did not contain.”
“Use “describe_coverage”: Returns the exact EN 16931 rules this server checks, the syntaxes it can produce and read, and the things it deliberately does not do, such.”
How secure is the InvoiceForge MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how InvoiceForge holds up.
Official endpoint
Operated by InvoiceForge (agenttoolworks.com) 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 InvoiceForge adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

Choose InvoiceForge in the gate directory. No sign-in needed.

InvoiceForge's tools are live in every AI client you've connected — with rules and logging built in.

Who runs the InvoiceForge MCP server?
The InvoiceForge MCP server at a glance
https://invoiceforge.agenttoolworks.com/mcpQuestions, answered
Is there an official InvoiceForge MCP server?
Yes — InvoiceForge operates its own remote MCP server at invoiceforge.agenttoolworks.com. 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 InvoiceForge to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick InvoiceForge in the directory. No account or sign-in is needed. From then on, InvoiceForge's tools are available in every client you've connected to gate.
Do I need to host anything?
No. InvoiceForge runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the InvoiceForge 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 InvoiceForge in minutes. No credit card required.
