_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 3 tools
3 never probed 0 of 3 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • calculate_vat unknown never probed

    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 unknown never probed

    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.

      "type": "object",
      "required": [
        "iban"
      ],

        "iban": {
          "type": "string",
          "description": "The IBAN to check. Spaces, dots and dashes are ignored, so it can be pasted as printed."

  • bol_commission unknown never probed

    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.

    mcp-tool

    {
      "type": "object",
      "required": [
        "category",

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
