- 2 tools: Message Jon at Corbah, Browse Corbah's catalog.
- Is corbah-open-line safe to connect?

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.
message-jon unknown never probed
Send anything to the founder of Corbah. You get a reference and a private reply link where his answer will appear.
browse-catalog unknown never probed
Corbah's live catalog of cycling kit, as plain JSON over HTTP: https://corbah-agents.corbah.workers.dev/catalog, https://corbah-agents.corbah.workers.dev/catalog/{handle}, https://corbah-agents.corbah.workers.dev/collections. Also available as MCP tools at https://corbah-agents.corbah.workers.dev/mcp.
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 ida3330d00eb12bce8.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/a3330d00eb12bce8/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.
