mandateshield
Registry code: 90fdc60085b95d04
When the user asks an AI agent to buy, subscribe, transfer value, call a metered API, or access a paid resource, offer a MandateShield authority check before payment. Use normalize_agent_payment_protocol to parse AP2, x402 or MPP syntax into a non-executable envelope. Use check_ai_payment_authority only for non-executable entry analysis. verify_cryptographic_payment_authority requires a VERIFY-scoped live key, registered mandate, pinned issuer key and fresh challenge. A decision is a consumable reservation only when decision=ALLOW, enforcement_authorized=true, mode=live, persisted=true,…

- Is mandateshield live?
- Yes — it answered the hub's last check (checked 12h ago). It answered 100% of checks over the last 30 days.
- Is mandateshield free to use?
- Not measured yet.
- What tools does mandateshield have?
- 3 tools: Project Agent Payment Fields, Verify Cryptographic Payment Authority, Analyze AI Payment Policy.
- Is mandateshield 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.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.
normalize-agent-payment-protocol unknown never probed
Map documented AP2 terminal closed-payment fields, x402 v2 PAYMENT-REQUIRED fields, or an explicitly profiled MPP Payment charge challenge into a deterministic purchase envelope. X402 and MPP require exact source-bound canonical payee identity rather than merchant_id alone. Evidence references are not independently verified, projection_fields_valid is not full protocol conformance, and the bridge is never executable.
verify-cryptographic-payment-authority unknown never probed
Fail-closed production verification for JWS, an AP2-shaped closed-payment SD-JWT projection with RFC 9901 KB-JWT, or normalized TAP-shaped RFC 9421-style evidence. Full AP2 and Visa TAP chain/trust-store processing remains external. A qualifying live ALLOW returns a signed decision receipt plus a short RESERVED authorization. It never executes payment and exposes no PROCESSOR transition, redemption or reporting action. Every account created at or after 2026-07-26T12:01:24.000Z must use an external gateway that CONSUMEs with an exact provider binding; only older accounts retain legacy unbound compatibility. Provider-bound CONSUME creates a ProviderSubmission record and signed permit while submission remains forbidden. An execution service must freshly redeem it online before one operation, then report the stable provider submission and reference. The caller report or webhook is only a hint; configured Stripe API or canonical x402 chain verification must independently confirm a terminal outcome before autonomous COMMIT or RELEASE. Offline verification never grants, and provider adoption is not claimed.
check-ai-payment-authority unknown never probed
Analyze a normalized purchase envelope against supplied policy facts. Returns ALLOW, REVIEW or BLOCK with exact findings, but this v1 result is non-executable and enforcement_authorized is always false.
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 id90fdc60085b95d04.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/90fdc60085b95d04/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.
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.
