What is the Japan Law Search MCP Server?

Full-text search of all current Japanese laws (official e-Gov data), down to exact article text.

The short version

This MCP server searches and retrieves the full text of current Japanese legislation — acts, cabinet orders, and ministerial ordinances — from the official e-Gov Laws API (Government of Japan). Built for legal-tech, compliance, HR, and contract-review AI agents working with Japanese law.

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
search_laws	Full-text search across the body text of every current law (or search by law title). Returns matched snippets, law categories, promulgation dates, and official links.
get_law_structure	Table of contents for any law: chapters, sections, and article headings. Long statutes (e.g. the Civil Code with 1,000+ articles) are automatically compressed to chapter level to save tokens.
get_law_article	Retrieve the exact text of any article. Accepts flexible references — 3, 第3条, 第三条の二, 3の2 — and normalizes kanji numerals automatically. Output preserves paragraph and item numbering as clean plain text.
