Japan Official Statistics — questions

Answers built from our own checks of this server.

What can Japan Official Statistics do?
It exposes 2 tools, read directly from the server on our last check. Among them: get_statistics_data, search_statistics. 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 Japan Official Statistics working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 182 checks got a reply (0.0%), average response time 66 ms. The bar chart above shows every period we have measured.
The registry lists Japan Official Statistics 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 Japan Official Statistics?
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 Japan Official Statistics need an API key?
No. Japan Official Statistics completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
