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.

Deprecated: use factrail_verify instead. Use only when an older integration still calls this experimental tool; financial and credit data sources are unavailable and returned fields are null.

Deprecated: use factrail_assess instead. Use when an older integration still expects the legacy beta EU import assessment format; coverage may be partial or provisional and this is not a binding customs result.

factrail_get_receipt reads unknown 16d ago

factrail_assess reads unknown 16d ago

Use when you need a source-backed assessment of importing a product into the EU (tariff classification, duties, and related evidence). Returns an EvidenceEnvelope; import assessment is Beta and results expose source coverage and support levels.

_ try it 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.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /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-endpoint with this listing's id ba3a610268cbfbe0.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/ba3a610268cbfbe0/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 know

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

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.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
