- Is used-car-index live?
- Yes — it answered the hub's last check (checked 55m ago). It answered 100% of checks over the last 30 days.
- Is used-car-index free to use?
- No — it asks for a key or a login before it will serve.
- What tools does used-car-index have?
- 3 tools: listing_changes, compare_vehicles, vehicle_risk.
- Is used-car-index 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. Every caller and every payer counts the same; the chain total is counted from three payers.

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.
listing_changes auth-required 55m ago
Returns paginated observations of listing changes with VIN, price, mileage, dates, source and link, filtered by vehicle, event type or date. Collector status distinguishes an inactive feed from observed events. There are no photos or dealer-written text; a delisted event means only that the listing was no longer observed and does not establish a completed transaction.

Returns compact recorded facts for two to five vehicles and factual orderings by complaints, recalls and available verified complaints-per-100k-sold rates. Unknown vehicles include database suggestions; unrated vehicles remain explicitly unrated. Counts reflect source coverage and a sales proxy where available; the comparison makes no recommendation, verdict or safety ranking.

Returns recorded NHTSA complaint flags, component counts, recalls, investigations, manufacturer communications, source coverage, an optional verified sales-denominator rate, and separately labeled Jev model tags for one make, model and year. Tags cover model years 2012 and newer, about 43 percent of complaints overall. model_tags includes model/schema provenance, tagged_complaints, complaints_total, tagged_share and per-label counts, shares, mean_confidence and high/low confidence counts. Confidence is the model probability for its chosen label (0 to 1), not accuracy. NHTSA flags stay in complaints. Absent tags are null with model_tags_null_reason. Family spellings are resolved from the database. These are observed records, not a prediction, safety rating, verdict, repair advice or an individual vehicle history.

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 idf88420736e8a178f.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/f88420736e8a178f/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.
