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 reads 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.
{ "type": "object", "required": [ "amount", "customer_country" ], "properties": { "amount": { "type": "number", "description": "Net amount (excluding VAT) in euros." }, "category": { "type": "string", "description": "Optional product category, used to find a reduced rate (books, food, medicine and similar)." }, "is_business": { "type": "boolean", "description": "True when the buyer is a business (B2B). Reverse charge also needs a valid VAT number." }, "seller_country": { "type": "string", "description": "Two-letter country code the seller is established in. Defaults to NL." }, "customer_country": { "type": "string", "description": "Two-letter country code the goods are shipped to, e.g. NL, DE, FR. This is what determines the rate." }, "customer_vat_number": { "type": "string", "description": "Buyer VAT number. Required for B2B reverse charge; it is checked against VIES, so an invented number will not zero the VAT." } } }arguments 33 linesbol_commission reads 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.
{ "type": "object", "required": [ "category", "price" ], "properties": { "price": { "type": "number", "description": "Selling price in euros, including VAT, as shown to the buyer." }, "category": { "type": "string", "description": "bol.com main category, in Dutch. For example: Elektronica, Boeken, Speelgoed, Wonen & Koken." }, "subcategory": { "type": "string", "description": "Subcategory when the main one splits by rate, e.g. Telefoons or Televisies under Elektronica." }, "fulfilment_type": { "enum": [ "lvb", "fbr", "all" ], "type": "string", "description": "lvb for Logistiek via bol, fbr when the seller ships. Leave out if it does not matter." } } }arguments 30 linesvalidate_iban reads 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" ], "properties": { "iban": { "type": "string", "description": "The IBAN to check. Spaces, dots and dashes are ignored, so it can be pasted as printed." } } }arguments 12 lines
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.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's ide9662a9419e03441.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
