How MCP servers expose tools in the first place →
Is Japan Subsidy Search working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 182 checks got a reply (50.0%), average response time 960 ms. The bar chart above shows every period we have measured.
How do I connect Japan Subsidy Search?
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 Subsidy Search need an API key?
No. Japan Subsidy Search 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.
How fast is Japan Subsidy Search?
It answers our handshake in 960 ms on average, which is faster than 6% 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.
Is Japan Subsidy Search open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
