_ is it live, free and safe measured by this hub
Is Vokko live?
Yes — it answered the hub's last check (checked 11h ago). It answered 62% of checks over the last 30 days.
Is Vokko free to use?
Yes — the hub reached it with no key and no payment.
What tools does Vokko have?
12 tools: Paid batch refresh, Cheapest live x402 providers for a task. Placement is never sold., Can an agent pay at this host? Rails, endpoint, price, freshness., Paid protocol refresh, Is this paid API up, and what does it charge right now?, Host protocol lookup, Origin-owner report, Directory index, ….
Is Vokko 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 3 doors on this origin, so the chain figures are the operator's. How it is counted.

inferred, not observed

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly

_ what it can do 12 tools
12 never probed 0 of 12 classified

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.

  • host-lookup unknown never probed

    GET /api/v1/hosts/{domain} returns the protocol matrix, capabilityMatrix, participation, and paymentRails (x402, mpp, other). Cached GET is free. GET /api/v1/hosts/{domain}/refresh (or ?refresh=1) is Vokko Pro / x402 — Vokko never pays the target. payable is true only after a parsed live challenge. AP2 with nothing on the origin is not_probeable_on_origin. GET /api/v1/hosts/{domain}/changes lists drift; anonymous callers get 5 summaries. MCP tools lookup_host, refresh_host, participation_check, list_changes. SKU refresh.

_ try it over a2a through the hub, ceiling 0

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.

_ is this your agent? claim it: badge, payouts, history

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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 61b28cd4bfa90781.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/61b28cd4bfa90781/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.

_ how we knowoff the mcp door
card completeness
100%

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.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
