aspern
Registry code: a8431cf4a6a42b02
Independent evidence about autonomous capital and the agent economy. The counterparty tools answer what the chain records about an address before you pay or hire it. Every figure states what it cannot see; quote those limits with the numbers. Tool descriptions change between releases: toolsManifest (959b2f5f515f7d47) names the current list and rides on every answer; if it differs from the list your client holds, reload tools/list.

- Is aspern live?
- Yes — it answered the hub's last check (checked 10m ago). It answered 99% of checks over the last 30 days.
- Is aspern free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does aspern have?
- 7 tools: Work out which party an identifier belongs to, Find agents by their record, How that record has moved, Check a list of counterparties, Check a payment before you send it, Check a counterparty before paying it, Judge a vault decision before capital moves.
- Is aspern 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 2 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.
identify reads unknown never probed
Give it a transaction hash, an http(s) URL, a hostname or an ERC-8004 registration number and it says which party that is, with the evidence for the link. Where more than one party matches it returns none and lists them all rather than picking. Free.
find_agents reads unknown never probed
Filter every address ever paid on x402, ACP, the Olas mech marketplace or Masumi by what it has actually done. Free.
counterparty_history reads unknown never probed
The same record day by day, so a good history can be told from a recent one. Paid.
counterparty_bulk reads unknown never probed
Up to fifty addresses in one call, each with its observations. Paid, per call rather than per address.
preflight_payment reads unknown never probed
Weighs one proposed payment against the record: the price the seller published for that endpoint, the payee that endpoint names, the largest payment the address has ever received, and whether it has been paid on the chain you are about to use. Three verdicts, and it never says a payment is safe. Free.
counterparty_check reads unknown never probed
What the chain records about an address: counterparties that paid it and were never paid back, the ones it pays back, how concentrated its custom is, how its jobs ended, whether its service answers, when it was last paid. Free.
evaluate_vault_decision unknown never probed
Send a proposed allocation, the mandate it must stay inside and the claims it rests on; get a verdict against our due-diligence snapshot of the vault, every finding citing the field it rests on. Paid; free as a dry run and on the two public sample vaults.
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 ida8431cf4a6a42b02.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/a8431cf4a6a42b02/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.
