Nothing serious here today

Today is the operative word: we check Agent Transaction Trust every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

verify

verify_settlement

Free post-payment step. Call only after the merchant x402 payment for a previously approved authorization or transaction clearance. Verifies the Base USDC settlement on-chain and, when it matches the authorization, returns a signed settlement receipt. The authorization_token may come from clearance_x402_ap2 or authorize_x402_ap2; payment_response is the merchant x402 PAYMENT-RESPONSE when available. No additional Trust fee is charged.

verify_trust_token

Free, read-only token check. Use this to validate the signature and expiry of a Trust policy, authorization token, transaction clearance token, or settlement receipt; it does not perform on-chain settlement verification.

ap2

create_ap2_challenge

Free prerequisite for AP2-native transaction clearance or authorization. Call before clearance_x402_ap2 or authorize_x402_ap2, bind the returned challenge into the AP2 Payment Mandate proof, then pass that challenge token as ap2_authority.challenge_token. The challenge is short-lived and intended for one purchase flow.

authorize

authorize_x402_ap2

Paid pre-payment trust gate. Use after create_ap2_challenge and after receiving the merchant's real x402 PAYMENT-REQUIRED challenge, but before paying the merchant. Verifies AP2 v0.2 authority and binds approval to the exact merchant challenge and HTTP request. On approval returns authorization_token; next pay the merchant, then call verify_settlement. Machine price: $0.001 via x402. If authorization is denied, the Trust fee is not settled/charged.

clearance

clearance_x402_ap2

Paid transaction-clearance decision for an autonomous x402 purchase. Use after create_ap2_challenge and after receiving the merchant's real PAYMENT-REQUIRED challenge, but before paying the merchant. Verifies AP2 v0.2 authority, exact request/challenge integrity, and public merchant-risk evidence. Returns clearance_decision APPROVED, REVIEW or DENIED and a signed clearance_token. APPROVED may proceed automatically; REVIEW should not auto-pay; DENIED should not pay. Machine price: $0.001 via x402.

preflight

preflight_x402

Paid public preflight for an autonomous x402 payment. No account, API key, policy token, or AP2 mandate is required. Submit the merchant's real PAYMENT-REQUIRED challenge and the exact intended HTTP request. Returns preflight_decision APPROVED, REVIEW or DENIED plus a signed preflight_token. APPROVED means the payment/merchant evidence is clear enough to proceed only if separate delegated authority permits the spend. Machine price: $0.001 via x402.

trust

get_trust_manifest

Free, read-only entry point. Call this first when deciding whether Agent Transaction Trust fits an x402 purchase. Returns capabilities, supported authority modes, proof key, price/network information, and the endpoints needed for transaction clearance, authorization, and settlement verification.

Agent Transaction Trust — questions

Answers built from our own checks of this server.

What can Agent Transaction Trust do?

It exposes 7 tools, read directly from the server on our last check. Among them: authorize_x402_ap2, clearance_x402_ap2, create_ap2_challenge, get_trust_manifest, preflight_x402, verify_settlement and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Agent Transaction Trust working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 277 ms. The bar chart above shows every period we have measured.

How do I connect Agent Transaction Trust?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Agent Transaction Trust need an API key?

No. Agent Transaction Trust completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Agent Transaction Trust?

It answers our handshake in 277 ms on average, which is faster than 60% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
