- Is trace live?
- Yes — it answered the hub's last check (checked 19m ago). It answered 99% of checks over the last 30 days.
- Is trace free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does trace have?
- 3 tools: get_trace, trace_payment, list_supported_systems.
- Is trace 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.

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.
list_supported_systems reads open 17h ago
List what Trace supports and can do: assets (USDC), chains with public tracing (Base, Solana), providers requiring connected credentials (Bridge, Circle), and explicit capability flags (read-only; cannot send, retry, or sign). Call this when unsure whether a payment is in scope for trace_payment.
{ "type": "object", "properties": {} }arguments 4 linesget_trace reads unknown 17h ago
Retrieve an existing Trace payment trace by its trace_id (tr_...), including the stage timeline. Read-only. Same normalized representation as trace_payment.

Use this whenever you need to determine whether a supported stablecoin payment completed, failed, or is delayed — where the money currently is, who owns the next step, and what should happen next. Typical triggers: 'the recipient says the payment never arrived', 'this payout is stuck', 'did this transaction go through?'. Give it a Base transaction hash, Solana signature, Bridge transfer ID, Circle payment ID, or a Base/Solana wallet address (USDC). Trace correlates blockchain and provider evidence into one deterministic normalized state: completed/terminal flags, health, current stage and owner, an evidence-backed diagnosis code with a machine-readable suggested action and retry timing, and a knowledge model separating observed facts from inferences from what Trace cannot see (e.g. beneficiary bank credit — onchain finality never proves the recipient's bank credited funds; unknown never means failed). Public blockchain data works without authentication; provider-connected state requires an API key. If the user has no identifier, ask for a transaction hash, provider payment ID, or supported wallet address. Read-only: this tool never moves funds, retries payments, signs transactions, or guarantees beneficiary receipt — do not use it to send or swap anything. If a payment's state is unresolved, do NOT send a replacement payment; follow the returned warnings and suggested action instead.

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 id1788475dd1c63aa4.

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.
