x402fix — questions

Answers built from our own checks of this server.

What can x402fix do?

It exposes 1 tools, read directly from the server on our last check. Among them: check_x402_endpoint. 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 x402fix working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 82 ms. The bar chart above shows every period we have measured.

How do I connect x402fix?

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 x402fix need an API key?

No. x402fix 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.

How fast is x402fix?

It answers our handshake in 82 ms on average, which is faster than 97% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use x402fix?

The npm package @agentgate-builder/x402fix was installed 164 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
