scvd-general-store
Registry code: 6bc43ea6a8f6cbbf
scvd.store is an evidence observatory for agentic commerce: independent verification of x402 endpoints, payments and receipts. Before an agent pays an x402 endpoint, we check that it can be paid. After it pays, we check the signed receipt. Over time we watch endpoints and publish a dated, signed corpus. Sellers use it to prove a door works; buyers use it before spending. Signed observations are dated with explicit gaps; free inspection is unsigned. Not escrow, not a rating, not a guarantee. Free instruments: a preflight check on any x402 door, a conformance desk for any issuer's signed offers…

- Is scvd-general-store live?
- Yes — it answered the hub's last check (checked 54m ago). It answered 100% of checks over the last 30 days.
- Is scvd-general-store free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does scvd-general-store have?
- 3 tools: x402 endpoint preflight, x402 receipt verification, x402 endpoint-readiness dataset.
- Is scvd-general-store safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 37 doors on this origin, so the chain figures are the operator's. How it is counted.

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.
preflight_endpoint reads unknown never probed
Preflight an x402 endpoint: one unpaid probe answering whether the URL serves a well-formed x402 v2 challenge a stock client could sign, with every check named and defined defects by name. A shape check at one moment; never an uptime or delivery claim.
verify_receipt unknown never probed
Verify an x402 signed offer or receipt: structure, signature against the issuer's key (supplied or resolved from its did:web), liveness; a verdict with every check named. Establishes the bytes and the key, never settlement or delivery.
get_endpoint_readiness unknown never probed
Read what the signed weekly corpus holds about one host: rounds probed of rounds since first sighting, the last signed verdict, the tier with its fraction, the gaps counted against the observer. From the chain, not a live probe; a host never met comes back as never met.
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 id6bc43ea6a8f6cbbf.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/6bc43ea6a8f6cbbf/claim.
Over MCP: the claim_endpoint tool.

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.
