Overview

AI-generated overview

A remote MCP server that lets an assistant normalize and romanize Japanese addresses, look up postal codes, and count Japanese business days.

What you can do
Normalize and romanize Japanese addresses into consistent, readable forms. Look up postal codes for Japanese locations. Count Japanese business days, accounting for the Japanese calendar. The manifest lists no individual tools, so exact parameters are not documented here.
When to use it
Useful when working with Japanese customer, shipping or site data that needs clean addresses or romanized output, when validating postal codes, or when scheduling needs Japanese business-day counts.
Requirements
A remote streamable HTTP endpoint; no local package or runtime is needed. Authentication is required via OAuth, using an Authorization header carrying an MCPize API key; a free plan is mentioned. Network access to the hosted endpoint is required.
Before you install
An MCPize API key is required in the Authorization header, so keep it secret and check the plan's limits. Address and postal-code queries are sent to a third-party hosted service. The manifest lists no tools, so verify what data is transmitted before relying on it for sensitive records.

Installation

In SourceWeft

  1. Open Japan Business Data in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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.matanemaboroshi%2Fjapan-business-data/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. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

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.
