Japanese law in Harvey

Set it up

1. 1

   This is a workspace administrator's task: Harvey has the administrator add an MCP server and enable it for the workspace. Send them this page, or the URL:

   Remote MCP server URL (HTTPS)Copy

   https://japanlaw.org/mcp

2. 2

   The server needs no sign-in and holds nothing about your matters: it only reads the published law. Harvey's documentation asks for OAuth 2.1 where a server requires authentication; this one requires none. If your workspace will only accept a server with OAuth, raise it with your Harvey contact.

3. 3

   Once enabled, ask Harvey's assistant to use japanlaw.org when Japanese statute is in question, and to keep the source line under each English paragraph.

Before you start

• Harvey also keeps a Connector Library of partner servers, which it reviews; that listing is something japanlaw.org would apply for, not something you need to wait on.
• Only the Japanese as published by the government has legal effect. The Ministry of Justice's translations are references, and this site's machine translations are marked as such on every paragraph.
• A citation into a law japanlaw.org does not hold is marked and left unresolved, and the assistant says when a law is not held.

Then ask

• Summarise the conditions under 労働基準法 第三十六条 for a valid overtime agreement, citing each paragraph with its japanlaw.org link.
• Which provisions of the Companies Act cite Article 362? List them with links.
• Compare the Ministry of Justice's English of 借地借家法 第二十八条 with the Japanese, and flag any paragraph that has only machine translation.

What Harvey can do with it

search

Finds provisions, laws and defined terms by Japanese or English words, in every law held or in one, best match first. Each result has an id for fetch and the page's URL.

fetch

Reads what a search result's id names: a provision in Japanese with its English, each line marked as the Ministry's translation or machine translation — in force, or as it stood on a day; or a law's overview and outline.

list_laws

Every law japanlaw.org holds: title, number, kind, date of the text in force and how much of it has English.

get_law

One law: what it is for, who it binds and who it does not — its exceptions and how it is enforced on request — the texts of it held, earlier and to come, and its chapters, or what is under one of them.

get_provision

An article, paragraph or item by its citation — 第三十六条第二項, Article 36(2) or art-36/par-2 — in Japanese and English, with what it cites, the terms it defines and its URLs: in force, or as it stood on a day. Shown as a card where the app can draw one.

get_citing_provisions

Every provision in the collection that cites the one given, with links. No official source publishes this direction.

get_definitions

The words a law defines for itself — 労働者, 賃金 — each with the statute's own definition, its English and whose that is, a plain explanation, where it is defined and how far it reaches. Given a provision, the definitions that apply in it and the legal vocabulary it uses.

get_amendments

A law's amendments: the amending Act, its number, the day it takes effect and whether it is in force. Given one, every provision it changes, before and after, in Japanese and English, each English marked as the Ministry's or machine translation.
