Ce que fait ce MCP

Provides x402 provider liveness rankings and retrieves or verifies Ed25519-signed routing and payment receipts.

Capacités

Outils

3 outils
get_rankings
Get TrustBench liveness rankings for x402 providers by capability. Returns a scored list of providers with latency and success-rate telemetry. Methodology note: scores are derived from HEAD-probe liveness checks (3 samples from one host), not a rigorous benchmark. See trustbench.io/methodology. Output: returns a JSON array. Each object has name (string, provider name), score (number 0-100, composite liveness score), latency_p50 (number, ms), success_rate (number 0.0-1.0, last 7 days), endpoint (string, URL), capabilities (array of strings).

get_receipt
Fetch a TrustBench routing receipt by ID. Receipts are immutable, Ed25519-signed records of a routing or payment event. Use to verify what was paid, to whom, for what capability, and what the on-chain settlement reference is. IDs start with rcpt_ (Phase 3) or rrcpt_ (Phase 4). Output: returns the signed receipt envelope as JSON. Phase 3 (rcpt_) returns a SignedReceipt with receipt (call metadata + settlement ref) and signature (Ed25519 over JCS-canonicalized receipt body). Phase 4 (rrcpt_) returns {receipt, signature} where receipt.paid contains routing details and signature covers the canonical envelope. To verify an envelope offline use the verify_receipt tool with the returned JSON, or @trustbench/verify-receipt npm.

verify_receipt
Verify the Ed25519 signature on a TrustBench receipt. Two modes: (1) Lookup mode — pass receipt_id and the server fetches the receipt from trustbench.io and re-runs verification (handy when you only have an ID). (2) Offline mode — pass receipt_json (the full {receipt, signature} envelope an agent received from a third party) and the server verifies the Ed25519 signature against the published public key at trustbench.io/.well-known/trustbench-pubkey without trusting the database. Exactly one of receipt_id or receipt_json must be provided. Output: returns JSON with receipt_id, signature_valid (boolean), on_chain_verified (boolean, where present), signature_alg ("ed25519"), verify_url, pubkey_url. For non-server-mediated verification with no network round-trip, use the @trustbench/verify-receipt npm package.
