Japan Company Info MCP server
by dqj1998
Look up Japanese company financials, registration numbers, shareholders and certifications from your AI chat.
This is a helper that lets your AI answer questions about Japanese companies using official government data. It works fully on your own computer, so nothing you ask gets sent to a company's servers. It is handy if you check companies for work, like research, finance, or compliance.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what it already learned. An MCP server is a small helper program that gives your AI a new skill or a connection to a service. This one connects your AI to official Japanese company records, like tax office registration numbers and financial filings. So when you ask about a company, your AI can look it up through this helper instead of guessing.
What this MCP server does
You ask your AI something like the financials for a Japanese company. Your AI passes that question to this helper program running on your computer. The helper searches a built-in index of official records, such as tax registration data, financial filings, shareholder lists and government certifications. It finds the matching entries and hands them back to your AI. Your AI then explains the answer to you in the chat, in plain words.

What it gives back to you
You get back a written answer in the chat, often with a small list or table of figures. For example, it might show several years of revenue and profit, a shareholder list with percentages, or a company's registration details. If the company is not in the free dataset, it tells you the closest matches it found instead.
