qart-uk
Registry code: 765b149110ecb7b6
qart.uk makes QR codes where the artwork IS the code — every image is decoded by a real QR detector before it is offered, so what you get is artwork that already scanned. Three ways to get one: a free pool of finished codes anyone with an account can claim and point at their URL, a paid Studio that generates custom ones from prepaid credits, and a single finished QR bought outright over x402 with no account at all (buy_qr_outright).
THE ONE THING TO GET RIGHT WHEN CHOOSING A RAIL: whether the finished code can be RE-POINTED after it is printed. That is a property of the payload, not of the…

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

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.
qr-pool-browse unknown never probed
List the pre-generated, scan-verified QR artwork currently claimable for free, one per style, with a preview image URL for each. Works without credentials; claiming one requires a signed-in account.
qr-generate unknown never probed
Generate scan-verified QR artwork for a destination URL and a described style. Returns a Task: images arrive as artifacts one at a time over several minutes, each carrying its own scan verdict, and the task can be cancelled at any point. SPENDS REAL MONEY — requires an OAuth bearer token with the qart:studio scope, and consumes the account's prepaid credits.
qr-buy unknown never probed
How to buy one scan-verified QR artwork outright, paying from your own wallet over x402 — no account, no bearer token, no credits. Asking here returns the live price and the exact call to make; the purchase itself is an HTTP request to https://qart.uk/api/v1/qr, because a payment needs a PAYMENT-SIGNATURE header and this JSON-RPC transport has nowhere to put one. That endpoint answers 402, and on the paid retry the PNG comes back in the response. You are charged ONLY if a real QR detector decodes the image: settlement follows the scan verdict, so a request that produces nothing scannable costs nothing.
qr-resolve unknown never probed
Given a scanned qart.uk code or its alias, report where it currently points, or that it has been retired. Does not count as a scan and does not affect the owner's statistics. Works without credentials.
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 id765b149110ecb7b6.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/765b149110ecb7b6/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.
