check_payment_flow
Verifies an agent's x402 payment flow against a free Base Sepolia testnet endpoint. Call with no arguments first to get back the payment-required challenge (price, network, payTo). Sign it with your x402 client, then call again passing paymentSignature as the encoded PAYMENT-SIGNATURE header value to get back a verified/failed receipt.

Micropay Test Suite — questions

Answers built from our own checks of this server.

What can Micropay Test Suite do?
It exposes 1 tools, read directly from the server on our last check. Among them: check_payment_flow. 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 Micropay Test Suite working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 124 ms. The bar chart above shows every period we have measured.
The registry lists Micropay Test Suite as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Micropay Test Suite?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Micropay Test Suite need an API key?
No. Micropay Test Suite completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
