Overview

AI-generated overview

Provides free EU VAT, IBAN and bol.com commission tools for marketplace sellers through a remote MCP endpoint.

What you can do
This remote MCP server exposes free tools related to EU VAT, IBAN handling and bol.com commission calculations for marketplace sellers. It is hosted at a remote endpoint and connects over streamable HTTP, so no local package is installed. The registry description lists no individual tool names or parameters.
When to use it
Worth considering if an assistant needs to help with EU VAT questions, IBAN details, or bol.com commission figures for marketplace selling. It is not aimed at general development, data, or productivity workflows.
Requirements
A remote MCP client that supports streamable HTTP, plus network access to the provider's endpoint. No packages, environment variables, headers or authentication are declared in the manifest.
Before you install
The manifest declares no authentication, so it is unclear what data is sent to the remote provider or how it is handled. No tool list is published, so verify the actual tools and any data they transmit before relying on results for tax or payment decisions.

Installation

In SourceWeft

  1. Open WinkelFactuur 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/nl.winkelfactuur%2Ftools/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

Tools

calculate_vat

Calculate Vat Tool

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_iban

Validate Iban Tool

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.

Parametersibanrequired

bol_commission

Bol Commission Tool

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.
