InvoiceForge missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

describe

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 as transmitting invoices over Peppol or acting as a French accredited platform. Light read: costs 0.2 credit.

extract

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 rather than guessing it. Use it to ingest supplier invoices before booking them. Costs 1 credit.

generate

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 for you. Choose the plain EN 16931 profile or the Peppol BIS Billing 3.0 customization. The document is validated before it is returned, so you never get back XML that would be rejected. Costs 1 credit.

usage

get_usage

Returns your current plan, remaining credit balance and call volume over the last 30 days. Free to call.

validate

validate_invoice

Checks invoice data against a documented subset of the EN 16931 business rules: mandatory fields, code lists, VAT category consistency and the arithmetic that most often gets invoices rejected. Accepts incomplete or malformed data on purpose, since that is what you want checked, and answers with each violation, its rule identifier and its business term, plus exactly which rules were checked. It never claims full compliance with the norm. Costs 1 credit.

InvoiceForge — questions

Answers built from our own checks of this server.

What can InvoiceForge do?

It exposes 5 tools, read directly from the server on our last check. Among them: describe_coverage, extract_invoice, generate_invoice, get_usage, validate_invoice. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is InvoiceForge working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 382 ms. The bar chart above shows every period we have measured.

How do I connect InvoiceForge?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does InvoiceForge need an API key?

No. InvoiceForge completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is InvoiceForge?

It answers our handshake in 382 ms on average, which is faster than 36% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is InvoiceForge open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
