verify_cryptographic_payment_authority
shallowcom.mandateshield/payment-authority · Verify this server
Use only for a production pre-payment authority gate after the caller has a registered mandate, pinned issuer key, fresh challenge, VERIFY-scoped key, exact final purchase and supported signed evidence. Fail closed 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 checkout/delegate-chain and Visa TAP structured-field/trust-store processing remain external. A qualifying live ALLOW creates only a short RESERVED authorization and cumulative-budget allocation. This MCP tool never executes payment and exposes no processor transition: a separate trusted gateway with an audience-bound PROCESSOR key must CONSUME and freshly redeem the provider-bound permit before attempting an idempotent provider operation, then reconcile the outcome.
