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.

  • card_drift_watch open 2h ago

    Hash a target agent card and detect drift between runs (B1). Fetches the target's agent card, computes SHA-256 over the canonical JSON, and compares against the previous run's hash stored in a state file. Reports DRIFT if the card changed, STABLE if unchanged, or FIRST_RUN if no prior state. A card change between runs without a re-registration event is a B1 signal: the deployed card drifted from the registered one. Cross-check against the ANS Transparency Log. Args: target_url: Agent card URL to watch. Defaults to the env-configured supplier. target_ans: Expected ANS name (e.g. 'ans://v1.0.3.supplier.webmesh.ai'). Must be in FRAUD_TARGET_ALLOWLIST. When set, the card's ANS identity is verified against this value before hashing or baselining — a mismatch returns INCONCLUSIVE so a wrong-cert card is never silently baselined as the target.

  • replay_settled unknown never probed

    Resubmit an already-used mandate to probe idempotency and on-chain nonce binding (H6). Submits the same mandate twice with fresh DPoP proofs each time.

  • run_battery unknown never probed

_ try it over mcp 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.

_ how we knowoff the mcp door
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
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
