Overview

AI-generated overview

A remote MCP server for Japanese address search and geocoding, letting an assistant look up addresses, postal codes and coordinates from the official address.

What you can do
Search Japanese addresses in the official address registry and resolve them to postal codes and coordinates.
When to use it
Useful when an assistant needs to look up or verify Japanese addresses, convert between addresses and postal codes, or obtain coordinates for locations in Japan.
Requirements
A remote endpoint; no authentication, environment variables or headers are declared. Network access to the hosted endpoint is needed.
Before you install
The manifest declares no authentication, so queries are sent to a third-party hosted service; avoid submitting sensitive personal address data you would not share with that operator.

Installation

In SourceWeft

  1. Open Japan Address & Geocoding in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.easakura%2Fjapan-address-geocoding-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
