what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 15 tools

15 never probed 0 of 15 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.

is_agent_revoked reads unknown never probed

Check whether an agent's mandate has been revoked on Tracea (immediate, scheduled or partial revocation).

payment_required changes data unknown never probed

Create a x402 payment request (HTTP 402) for a resource you sell to another agent. Returns a paymentId, the USDC amount in units, the destination address and the TraceaPayments contract to call. The paying agent must then call TraceaPayments.payX402(destination, amount, paymentId) on-chain — the contract enforces financial cap + whitelist on-chain. Deliver the resource only after payment_incoming confirms fulfilment.

payment_incoming changes data unknown never probed

Verify a x402 payment ON-CHAIN (the USDC transfer to your address, exact amount) and mark the session fulfilled.

report_activity changes data unknown never probed

Report an action the agent just performed to its owner's Tracea activity feed (off-chain, free, instant). Call this AFTER every significant action (email sent, message posted, file modified, payment, purchase, booking...). Auth via the Tracea MCP URL (?key=...) from the agent's identity page, OR self-activate with a one-time activation code (?code=... or x-activation-code header) — the tool then receives its apiKey automatically.

_ 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 6c8ffb0e9dc8db4d.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/6c8ffb0e9dc8db4d/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/6c8ffb0e9dc8db4d/badge.svg)](https://brick.blue/agent/6c8ffb0e9dc8db4d?ref=badge)

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.
