README
# Japan Law Search MCP — 日本の法令検索 **Give your AI agent authoritative access to all ~10,000 Japanese laws and regulations.** 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](https://laws.e-gov.go.jp/) (Government of Japan). Built for legal-tech, compliance, HR, and contract-review AI agents working with Japanese law. ## Why this server? Japanese statutes are published as deeply nested XML with kanji numerals, era-based dates, and no convenient full-text API surface for LLMs. This server turns that into three clean, token-efficient tools. ## Tools ### `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. ## Example queries your agent can now answer - 「電子署名法で電子署名が有効とされる条件は？」→ finds Article 3 and quotes it verbatim - "What does the Labor Standards Act say about overtime limits? Quote the exact article." - 「個人情報保護法の目次を見せて、第三者提供に関する条文を特定して」 ## Data source & freshness Official e-Gov Laws API v2 (Government of Japan), fetched live on every call — always the currently enforced revision, including amendments enforced this month. ## Pricing Pay per tool call. One search, one table of contents, or one article retrieval = one event. No subscription, no minimum. --- ### 日本語 日本の現行法令（約1万件）を全文検索し、条文を取得できるMCPサーバーです。巨大な法令XMLをAIが読みやすいテキストに整形し、「第三条の二」等の表記ゆらぎも自動吸収します。リーガルテック・コンプライアンス・労務系AIに最適です。 ## Get started This is a hosted (remote) MCP server, available on Apify Store: 👉 **https://apify.com/e-asakura/japan-law-search-mcp** The store page includes setup instructions for Claude, ChatGPT, Cursor, and any MCP-compatible client.
