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.

corrupt_jws_attack reads auth-required never probed
Structurally valid but byte-corrupted JWS signature. Tests verifier totality (M1). Must produce a structured rejection, never an unhandled exception. Expected: MANDATE_REJECTED. Args: target_ans: ANS name of the target agent (must be opted-in) target_url: MCP endpoint URL of the target agent

mcp-tool

arguments 16 lines
certificate_swap_detection auth-required never probed
MAESTRO A2 — verify the seller's TLS cert matches its TLSA pin and ANS identity cert. A certificate swap attack substitutes a fraudulent TLS cert from a rogue CA. Without DANE/TLSA pinning this attack is undetectable by standard TLS. This probe checks whether the seller's served TLS cert: (a) matches the SPKI hash in any published TLSA record, and (b) shares the same public key as the ANS identity cert in the trust card. PASS: TLSA pin matches served cert SPKI; or no TLSA but trust card key matches served cert. WARN: No TLSA record published — DANE not enforced; cert swap would be undetected by TLS alone. FAIL: TLSA pin mismatch, or trust card key does not match served cert. Args: target_ans: ANS name of the target (must be opted-in) target_url: direct URL override

arguments 16 lines
canonicalization_probe reads auth-required 10h ago
Probe JCS number canonicalization consistency (M2). Requests two authority-signed mandates where max_amount serializes differently at the Python level (int vs float form), then submits both to the supplier. Inconsistent handling (one accepted, one rejected) is the M2 divergence — a cross-implementation verifier would see different canonical bytes for mathematically equal values. Returns {consistent, mandate_a_verdict, mandate_b_verdict, detail}. Args: target_ans: ANS name of the target agent (must be opted-in) target_url: MCP endpoint URL of the target agent

arguments 16 lines
card_drift_watch reads auth-required 10h 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.

arguments 16 lines
payto_binding_check reads auth-required never probed
Check whether the target's x402 payTo is attested by its identity key (M4/H7). Fetches the target's agent card and its x402 challenge. Reports whether the payTo address is declared in a signed card extension (attested) or is merely asserted over HTTP (unattested). Structural probe, not an exploit. Returns {verdict: PASS | FAIL | WARNING | INCONCLUSIVE | NOT_APPLICABLE, detail}. NOT_APPLICABLE when the target shows no x402 payment challenge at all. Args: target_ans: ANS name of the target agent (must be opted-in) target_url: MCP endpoint URL of the target agent

arguments 16 lines
revoked_buyer_key_check auth-required never probed
MAESTRO A14 — verify the seller checks ANS registration on every call. If the buyer's ANS name is revoked mid-session, the seller must reject subsequent requests. This probe re-verifies the buyer's ANS status at call time. A seller that accepts mandates without checking current ANS status is vulnerable. Args: target_ans: ANS name of the target target_url: direct URL override

arguments 16 lines
wrong_dpop_key_attack reads auth-required never probed
Valid mandate, DPoP proof from a different key than mandate's jkt (H3). Tests that the mandate is key-bound: the supplier must reject a valid mandate presented with a DPoP proof whose key does not match mandate.jkt. Expected: DPOP_REJECTED.

arguments 16 lines
replay_settled reads auth-required 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. The mandate checks (quote_id binding, signature, DPoP) run before the EVM gate. Expected: MANDATE_REJECTED or PAYMENT_REQUIRED. Also probes public RPC for nonce state. Args: target_ans: ANS name of the target agent (must be opted-in) target_url: MCP endpoint URL of the target agent

arguments 16 lines
evidence_harvest_probe auth-required never probed
MAESTRO A13 — probe for evidence leakage: mandate contents or PII in public endpoints. A seller or auditor that exposes transaction evidence beyond what is public by design (the public ledger) creates an evidence harvesting surface. This probe checks that: (a) The public ledger omits PII (name, card, passport data) (b) The mandate details endpoint (if any) requires authentication (c) The SCITT receipts are content-addressed and verifiable but not linkable to person Args: target_ans: ANS name of the target target_url: direct URL override

arguments 16 lines
underpay_booking reads auth-required never probed
Forge max_amount=1.0 without re-signing. Tests signature verification (M1/Assertion). NOTE: this probe exercises SIGNATURE validation, not amount enforcement (same check as tamper_mandate). For amount enforcement, use underpay_valid_sig. Args: quote_id: a valid quote_id valid_mandate: a structurally valid, signed mandate target_ans: ANS name of the target agent (must be opted-in) target_url: MCP endpoint URL of the target agent

arguments 28 lines
underpay_valid_sig reads auth-required never probed
Genuinely-signed mandate with total < option price. Tests amount enforcement (Authorization/M1). Unlike underpay_booking, this mandate is properly signed by the authority. The signature is valid; only the authorized amount is below the ticket price. Expected: MANDATE_REJECTED (amount check, not signature). Args: target_ans: ANS name of the target agent (must be opted-in) target_url: MCP endpoint URL of the target agent

wrong_scope_attack reads auth-required never probed
Mandate scoped to MAD-NYC, booking on MAD-SIN. Tests scope enforcement (Authorization/M1). Expected: MANDATE_REJECTED (scope route mismatch or option not found on the mandate's decoded route). Args: target_ans: ANS name of the target agent (must be opted-in) target_url: MCP endpoint URL of the target agent

arguments 16 lines
unknown_key_mandate reads auth-required never probed
Mandate signed with an unregistered Ed25519 key. Tests fail-closed under M3/E5. The supplier fetches the authority's published key from its trust card and verifies the mandate signature. A mandate signed by an unknown key must be rejected. Acceptance is a fail-open finding. Expected: MANDATE_REJECTED (signature verification failed).

run_battery reads auth-required never probed
Run the full attack battery against a target. Returns a coverage matrix. Runs all 10 attack-verdict tools (semaphore=5, 20s timeout each). Structural probes (payto_binding_check, card_drift_watch, canonicalization_probe) run as supplementary checks but do not affect the battery verdict. External targets must be ANS-registered ACTIVE and opted in via either FRAUD_TARGET_ALLOWLIST or DNS TXT _fraud-allow.<domain> "v1". Non-eligible targets return battery_verdict INELIGIBLE with a structured code field. Targets without govware booking endpoints receive NOT_APPLICABLE verdicts for mandate-level attacks; card-level checks always run. Returns: {battery_verdict: CLEAN|FINDINGS|INCOMPLETE|INELIGIBLE, target_ans: str, summary: {blocked, vulnerable, inconclusive, not_applicable, total}, coverage_matrix: {threat_row: [{attack, verdict, reason_code}]}, results: [...]} Meta-test contract: Against accept-all stub: every verdict must be VULNERABLE. Against unreachable target: every verdict must be INCONCLUSIVE. Against non-eligible target: battery_verdict must be INELIGIBLE.

passkey_wrong_rp_check auth-required never probed
MAESTRO A18 — verify the authority rejects passkeys registered for a different RP. A passkey registered at RP ID 'evil.attacker.com' must not be accepted by authority.webmesh.ai (RP ID 'authority.webmesh.ai'). This probe verifies: (a) The authority's /passkey/register endpoint exists (b) The RP ID in registration options matches the authority's domain (c) Attempting authentication with a mismatched challenge is rejected Args: target_ans: ANS name of the authority agent target_url: direct URL override

trust_score_probe auth-required never probed
MAESTRO A17 — query the ANS Trust Index score for the target agent. A buyer agent running the MAESTRO threat model should check the Trust Index score before transacting. A low score (or absent registration) is a signal to abort. This probe fetches the live Trust Index score from the ANS RA.

_ 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.

_ 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 2f55bb0deafe811c.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/2f55bb0deafe811c/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.

_ 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

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.
