Japan Typhoon Tracker MCP — questions

Answers built from our own checks of this server.

What can Japan Typhoon Tracker MCP do?

It exposes 3 tools, read directly from the server on our last check. Among them: active_typhoons, storm_detail, storm_list. 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 Typhoon Tracker MCP 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 134 ms. The bar chart above shows every period we have measured.

How do I connect Japan Typhoon Tracker MCP?

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 Japan Typhoon Tracker MCP need an API key?

No. Japan Typhoon Tracker MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Japan Typhoon Tracker MCP?

It answers our handshake in 134 ms on average, which is faster than 85% 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.

Is Japan Typhoon Tracker MCP open source?

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