what callers paid
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.
list_elements open 12h ago
Elements (minerals, vitamins, protein) that have a LabelTruth page, with the number of products tracked in the whole catalogue.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "properties": {}, "additionalProperties": false }arguments 6 linesget_product unknown 12h ago

Chemical forms of one element that have at least one priced product in the region, in alphabetical order. No prices: forms are not ranked against each other.

Products of one chemical form ranked by euro per 1000 mg of the element, cheapest first, at the shop price when last checked. Only ranked products are listed (limit 1-10, default 5).

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 id156131efb58b31fe.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/156131efb58b31fe/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.
