Registry code: 55b004f3015e6159
Read-only access to free CC BY 4.0 grocery data from Yappman Data: the weekly UK and Australian online shelf-price index and the UK daily 212-item basket. Posted online shelf prices, not prices paid, not a CPI. Call about_the_data before citing; give the credit line each tool returns. Static snapshots, not live or real-time; may be incomplete or out of date. Provided as is, with no warranty; check the retailer before relying on a price. Independent: not affiliated with or endorsed by any retailer, government body or Apify.

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.
about_the_data open 1h ago
Returns the licence (CC BY 4.0) and credit form, what is not served, the store setting, the published index weeks and the basket date range with its short and missing days. Use it before citing or relying on the other tools.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 lineslookup_basket_prices unknown 1h ago
Returns posted shelf prices from the free UK daily 212-item basket (CC BY 4.0) for up to 20 barcodes (EAN) or retailer product ids, up to one row per retailer for one day: price, was-price, loyalty price, unit price, pack size and stock. Use it for "what did this barcode cost at Tesco, Sainsbury's, Asda or Aldi on a day". Static snapshot days, not live. Not for searching by product name, and only the 212 basket products are covered.

Returns the published weeks (vintages) of the free UK or Australian online shelf-price index, newest first, with publication time, revision and base week. Use it before get_shelf_price_index to pick a week. Not for prices.

Returns one published week of the free UK or Australian online shelf-price index (CC BY 4.0): index levels, week-on-week change and matched-product counts by retailer and product class. Use it for "how did posted grocery shelf prices move this week". Not a CPI, not prices paid, no product names. Omit vintage for the latest week; call list_index_vintages for the others.

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 id55b004f3015e6159.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/55b004f3015e6159/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.
