WinkelFactuur does not always answer

Over the last week it answered 98.6% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 3

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

bol

bol_commission

Work out what bol.com keeps from a sale: the commission percentage for the product category, any fixed fee, and what the seller is left with. Category names are the Dutch ones bol.com uses ("Elektronica", "Boeken", "Speelgoed"). If the category is unknown or missing, the tool returns the list of categories it knows, so call it again with one of those.

calculate

calculate_vat

Calculate EU VAT (Dutch: BTW) for a cross-border or domestic sale, using the destination-country principle that applies to e-commerce. Handles the cases sellers get wrong: OSS distance selling to another EU country, B2B reverse charge when the buyer has a VIES-valid VAT number, and zero-rated exports outside the EU. Rates are the statutory ones for the destination country, including reduced rates when a category is given.

validate

validate_iban

Validate an IBAN (bank account number) and report whether its check digits and country-specific length are correct. Catches transposed or missing digits before a payment or an invoice goes out with the wrong account number. This checks the number's structure, not whether the account exists or who owns it.

WinkelFactuur — questions

Answers built from our own checks of this server.

What can WinkelFactuur do?

It exposes 3 tools, read directly from the server on our last check. Among them: bol_commission, calculate_vat, validate_iban. 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 WinkelFactuur working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 84 of 91 checks got a reply (92.3%), average response time 562 ms. The bar chart above shows every period we have measured.

How do I connect WinkelFactuur?

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 WinkelFactuur need an API key?

No. WinkelFactuur completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is WinkelFactuur?

It answers our handshake in 562 ms on average, which is faster than 26% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
