Japanese Postal Code Lookup
This MCP server provides Japanese postal code address lookup functionality by integrating with the zipcloud.ibsnet.co.jp API service. Built by RookingOSS using Python with FastMCP and httpx, it offers a single tool for converting 7-digit Japanese postal codes into complete addresses by combining the prefecture, city, and district information from the API response. The implementation includes error handling for invalid postal codes and API failures, making it useful for applications that need to validate or auto-complete Japanese addresses from postal codes in customer forms, shipping systems, or location-based services.
