What your AI can do with it

  • Search more than 18 million legal documents worldwide
  • Find case law from over 110 countries
  • Look up legislation from covered countries
  • Retrieve legal doctrine to support research answers
  • Surface relevant legal documents when you ask a legal question

Install World Wide Law

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

  • Claude Code

    claude mcp add --transport http --scope user world-wide-law 'https://legaldatahunter.com/mcp'

    Run it once in your project, then open /mcp to approve any sign-in the server asks for.

  • Claude Desktop

    https://legaldatahunter.com/mcp

    Add a custom connector in Settings, paste this address, and approve the sign-in.

  • Cursor

    cursor://anysphere.cursor-deeplink/mcp/install?name=world-wide-law&config=eyJ1cmwiOiJodHRwczovL2xlZ2FsZGF0YWh1bnRlci5jb20vbWNwIn0=

    Open the link and Cursor adds the server at that address.

  • ChatGPT

    https://legaldatahunter.com/mcp

    In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.

  • Codex

    codex mcp add world-wide-law --url 'https://legaldatahunter.com/mcp'

    Run it once, then sign in with codex mcp login world-wide-law if the server asks for an account.

From the project's README

As published by worldwidelaw/legal-sources in README.md.

Open-source collection scripts for open legal data from 110+ countries.

Every country publishes its laws, court decisions, and regulations online -- but in different formats, behind different APIs, with different access rules. World Wide Law is building the open infrastructure to collect, normalize, and make all of it searchable.

All sources in this repository are open data -- publicly available legal information from official government portals, APIs, and bulk download endpoints. We always prefer API and bulk access over web extraction.

Live Dashboard & API

What's Here

This repository contains 960+ collection scripts across 110+ countries that download and normalize open legal data from government portals worldwide. Each script follows a standard interface so that any developer can run, test, or improve it. Some sources are marked as blocked (CAPTCHA, IP restrictions, etc.) -- their scripts are included so developers can review and potentially contribute fixes.

  FR/LegifranceCodes/     # French consolidated legal codes (API)
  DE/GesetzeImInternet/   # German federal laws (bulk XML)
  IT/NormattivaLegislation/ # Italian legislation (API)

Quick Start

# Clone the repo
git clone https://github.com/worldwidelaw/legal-sources.git
cd legal-sources

# Install dependencies
pip install -r requirements.txt

# Check project status
python runner.py status

# Test a specific source
python runner.py sample FR/LegifranceCodes

# See what needs work
python runner.py next

How It Works

Per-Source Structure

Every source lives in sources/{COUNTRY_CODE}/{SourceName}/ and contains:

FilePurpose
bootstrap.pyCollection script -- implements fetch_all(), fetch_updates(), normalize()
config.yamlSource metadata, access method, rate limits, schema
sample/10+ sample documents for validation
README.mdDocumentation about the data source
.env.templateRequired API keys or credentials (if any)
retrieve.pyReference resolver (e.g., "article 1240 code civil" -> document)

Two Data Models

Legislation (mutable): Laws get amended. Same ID, new content. Strategy: upsert with version tracking.

Case law (immutable): Court decisions don't change after publication. Strategy: append-only with dedup.

Standard Output Schema

Every script normalizes documents to a common schema:

  • _id -- Unique identifier
  • _source -- Source identifier (e.g., FR/LegifranceCodes)
  • _type -- legislation or case_law
  • title -- Document title
  • text -- Full text content
  • date -- Publication or decision date
  • url -- Link to the original source
