The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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 open 16h 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.

  • trace_payment unknown never probed

    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.

  • get_trace unknown never probed

    Retrieve an existing Trace payment trace by its trace_id (tr_...), including the stage timeline. Read-only. Same normalized representation as trace_payment.

_ 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
70%

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
0

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.
