x402 Tools — questions

Answers built from our own checks of this server.

What can x402 Tools do?

It exposes 13 tools, read directly from the server on our last check. Among them: domain_intel, exchange_rates, fda_recalls, free_url_check, github_repo, open_meteo_weather and 7 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 x402 Tools 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 2754 ms. The bar chart above shows every period we have measured.

How do I connect x402 Tools?

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 x402 Tools need an API key?

No. x402 Tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.

Is x402 Tools open source?

We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
