Overview

AI-generated overview

Lets an assistant normalize and verify Japanese postal addresses into structured fields.

What you can do
This remote MCP server takes Japanese postal addresses and normalizes and verifies them, returning structured address fields an assistant can use. It is a single-purpose address utility rather than a general data service. No tool list is published, so the exact operations are not documented beyond normalization and verification.
When to use it
Worth adding when an assistant regularly handles Japanese addresses and needs them cleaned up or checked before use, for example in forms, shipping, or data entry workflows. Not needed if you never work with Japanese postal addresses.
Requirements
A remote MCP endpoint at over streamable HTTP. No authentication, environment variables, or headers are declared, and no local package or runtime is required. Network access to the endpoint is needed.
Before you install
Addresses sent to the server leave your machine and go to a third-party endpoint, so avoid submitting personal or customer address data unless that is acceptable. The provider publishes no tool list, authentication, or privacy details, so the handling of submitted data is unclear.

Installation

In SourceWeft

  1. Open Jp Address 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/net.streamfront%2Fjp-address/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

Other MCP clients

Add this to your client's mcpServers config.

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.
