What can GhostKey — Route Paid APIs with x402 do?
It exposes 4 tools, read directly from the server on our last check. Among them: ghostkey_catalog, ghostkey_policy, ghostkey_quote, ghostkey_status. 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 →

We send a real MCP handshake every 15 minutes. Over the last 24 hours 183 of 186 checks got a reply (98.4%), average response time 1129 ms. The bar chart above shows every period we have measured.
How do I connect GhostKey — Route Paid APIs with x402?
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 GhostKey — Route Paid APIs with x402 need an API key?
No. GhostKey — Route Paid APIs with x402 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is GhostKey — Route Paid APIs with x402?
It answers our handshake in 1129 ms on average, which is faster than 5% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
