what callers paid
Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run
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.
price_history unknown never probed
Lowest daily total price of a product over time (all shops together), with the lowest price ever and the change versus 30 days ago. Use to answer "is this a good moment to buy?".
{ "type": "object", "required": [ "product_key" ], "properties": { "days": { "type": "integer", "default": 90, "description": "How many days back, 7-365." }, "product_key": { "type": "string", "description": "product_key from search_products or compare_prices." } } }arguments 17 linessearch_products unknown never probed
Search products and travel eSIM data plans at Dutch partner shops. Returns products (one entry per product, not per shop) with the lowest total price incl. shipping, the cheapest shop, how many shops sell it and whether any shop delivers next day. Use compare_prices with product_key to see every shop for one product.
{ "type": "object", "required": [ "query" ], "properties": { "shop": { "type": [ "string", "null" ], "default": null, "description": "Only this shop, e.g. \"bol\" or \"Coolblue\"." }, "sort": { "type": [ "string", "null" ], "default": null, "description": "Sort: relevance (default), price_low, price_high, fastest, most_shops." }, "brand": { "type": [ "string", "null" ], "default": null, "description": "Only this brand." }, "limit": { "type": "integer", "default": 8, "description": "Number of products, 1-24." }, "query": { "type": "string", "description": "What to find, in Dutch or English, e.g. \"philips airfryer xxl\", \"sony noise cancelling koptelefoon\", \"esim japan 10 dagen\"." }, "max_price": { "type": [ "number", "null" ], "default": null, "description": "Maximum total price in euros." }, "min_price": { "type": [ "number", "null" ], "default": null, "description": "Minimum total price in euros." }, "max_delivery_days": { "type": [ "integer", "null" ], "default": null, "description": "Only offers the shop promises within this many working days. 1 = next day (\"morgen in huis\")." } } }arguments 65 linesget_buy_link unknown never probed
Get the link where the user can buy the product on the shop's own website, plus the affiliate disclosure to show the user. Nothing is bought by this tool; the user completes the purchase at the shop.
{ "type": "object", "required": [ "offer_id" ], "properties": { "offer_id": { "type": "string", "description": "Offer id (from compare_prices, or cheapestOfferId from search_products)." } } }arguments 12 linescompare_prices unknown 52m ago
For one product, list every shop selling the same item (matched by barcode or brand + part number), cheapest total price first, with each shop's delivery promise. Answers "where is this cheapest" and "who delivers it tomorrow". Pass product_key or offer_id.
{ "type": "object", "properties": { "offer_id": { "type": [ "string", "null" ], "default": null, "description": "Or an offer id (e.g. cheapestOfferId from search_products)." }, "product_key": { "type": [ "string", "null" ], "default": null, "description": "product_key from search_products (preferred)." }, "max_delivery_days": { "type": [ "integer", "null" ], "default": null, "description": "Only shops that promise delivery within this many working days (1 = tomorrow)." } } }arguments 29 linestop_products unknown 52m ago
The best products for a need, e.g. "top 5 smartphones" or "best airfryer under 150 euro", ranked by the Tryvon score: buyer rating (review-weighted, so a few 5-star reviews don't beat thousands of 4.6-star ones), popularity, value for money and delivery speed. Commission plays no part. Returns rating, review count, lowest price, shops and key specifications per product. Products without reviews are marked hasReviews=false.
{ "type": "object", "properties": { "limit": { "type": "integer", "default": 5, "description": "How many, 1-10." }, "query": { "type": [ "string", "null" ], "default": null, "description": "What kind of product, e.g. \"smartphone\", \"noise cancelling koptelefoon\", \"airfryer\"." }, "category": { "type": [ "string", "null" ], "default": null, "description": "Or a category key from search results (categoryKey), e.g. \"smartphones\"." }, "max_price": { "type": [ "number", "null" ], "default": null, "description": "Maximum total price in euros." }, "max_delivery_days": { "type": [ "integer", "null" ], "default": null, "description": "Only offers the shop promises within this many working days (1 = next day)." } } }arguments 42 linescompare_products unknown 52m ago
Compare 2-4 different products side by side: every specification (rows where they differ are marked), buyer rating, lowest total price and shop, number of shops and delivery. Marks the cheapest, the best rated and the best choice (highest Tryvon score).
{ "type": "object", "required": [ "product_keys" ], "properties": { "product_keys": { "type": "array", "items": { "type": "string" }, "description": "2-4 product keys (productKey from search_products or top_products)." } } }arguments 15 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 id67df11e7cc2ff8c0.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/67df11e7cc2ff8c0/claim.

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.
