ReceiptRail does not always answer

Over the last week it answered 98.9% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 3

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

issue

issue_receipt

Anchor a SHA-256 digest of delivered content plus the x402 settlement reference on Solana. Returns a permanent, publicly verifiable receipt (poll until outcome === "settled"). Costs 0.001 USDC via x402; if x402_payment_signature is omitted, returns the payment challenge instead (pay 0.001 USDC to the service address, then call again with the payment tx signature).

receipt

get_receipt

Fetch full receipt details: digests, checks, outcome, amount, buyer, seller, timestamp, PDA. Look up by receipt_id, or by x402_payment_ref (always works — the receipt lives on-chain). Read-only, no cost.

verify

verify_receipt

Verify an AgentToll receipt against live Solana state: PDA owner must be the AgentToll program and the stored digest must match the receipt. Look up by receipt_id, or by x402_payment_ref (always works — the receipt lives on-chain). Read-only, no cost.

ReceiptRail — questions

Answers built from our own checks of this server.

What can ReceiptRail do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_receipt, issue_receipt, verify_receipt. 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 ReceiptRail 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 4732 ms. The bar chart above shows every period we have measured.

Did ReceiptRail ever remove tools?

Yes. verify_x402_receipt is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

Is ReceiptRail still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect ReceiptRail?

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 ReceiptRail need an API key?

No. ReceiptRail completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
