Available tools 1

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

normalize
normalize_jp_address
Normalize and verify a Japanese postal address. Splits a raw Japanese address string into structured fields (prefecture, city, town, block number, building, room) and returns a verification flag plus lat/lng. Handles messy input: full-width chars, mixed hyphens, romaji, and building/room separation that generic parsers miss.

Jp Address — questions

Answers built from our own checks of this server.

What can Jp Address do?
It exposes 1 tools, read directly from the server on our last check. Among them: normalize_jp_address. 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 Jp Address working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 1238 ms. The bar chart above shows every period we have measured.
The registry lists Jp Address 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 Jp Address?
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 Jp Address need an API key?
No. Jp Address completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Jp Address?
It answers our handshake in 1238 ms on average, which is faster than 3% 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.
