Mat Web & Data Toolkit (x402, Cloudflare) — questions

Answers built from our own checks of this server.

What can Mat Web & Data Toolkit (x402, Cloudflare) do?
It exposes 46 tools, read directly from the server on our last check. Among them: broken_sites_leads, btc_snapshot, convert, crypto, dataset_fx, dataset_worldbank and 40 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 →
What is Mat Web & Data Toolkit (x402, Cloudflare) mostly used for?
Its tools cluster around evm, dataset and x402. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Mat Web & Data Toolkit (x402, Cloudflare) 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 214 ms. The bar chart above shows every period we have measured.
Did Mat Web & Data Toolkit (x402, Cloudflare) ever remove tools?
Yes. broken_sites_leads_sample, flapjax_check are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect Mat Web & Data Toolkit (x402, Cloudflare)?
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 Mat Web & Data Toolkit (x402, Cloudflare) need an API key?
No. Mat Web & Data Toolkit (x402, Cloudflare) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 46 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Mat Web & Data Toolkit (x402, Cloudflare)?
It answers our handshake in 214 ms on average, which is faster than 66% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
