Overview

AI-generated overview

Gives an assistant read-only search and retrieval of Taiwan statutes, articles and apex-court decisions.

What it does
A hosted MCP server that lets an assistant search Taiwan law articles by concept, keyword or article reference, resolve law names, fetch a single article by number (with the official English translation where available), and browse a law's chapter and section outline or full text. It also searches apex-court decisions and Grand Chamber rulings, and can list every decision containing an exact phrase. All tools are read-only and query public legal data.
When to use it
Use it when you need grounded answers about Taiwan law: finding statutes or articles, checking a law's structure, or locating Supreme Court, Supreme Administrative Court, Constitutional Court or Grand Chamber decisions. It suits legal research and citation, not general web search.
Requirements
A remote Streamable HTTP endpoint; no local runtime or package. Sign-in uses OAuth 2.1 with a RegAI account (free, email code or LINE). Clients without sign-in support can instead send an API key from the account page as an Authorization Bearer header or a key query parameter. Queries and law names are in Traditional Chinese. Free tier allows 500 calls per month; MCP Pro requires a card.
Before you install
The Authorization API key is a credential: keep it private and revoke or regenerate it if exposed. Sign-in grants the assistant access to your RegAI account, and connected apps can be disconnected from the account page. Tool calls count against monthly and burst limits, and MCP Pro is a paid plan requiring a card. Results are research material, not legal advice, and the service is not affiliated with Taiwan's Ministry of Justice or Judicial Yuan.

README

RegAI Legal MCP

English · 繁體中文

Taiwan law and court decisions for your AI assistant: statutes, articles and rulings, read-only.

RegAI Legal MCP is a hosted Model Context Protocol server that gives AI assistants such as Claude and ChatGPT grounded access to Taiwan's laws and court decisions. Your assistant can search statutes by concept or keyword, fetch an article by number (with the official English translation where one exists), browse a law's structure, search apex-court decisions and Grand Chamber (大法庭) rulings, and list every decision that contains an exact phrase.

This repository holds the public documentation, the registry metadata (server.json) and examples. The server itself is a hosted service; its source code is not published here.

Data

  • Laws and regulations: Taiwan's Ministry of Justice national law database (全國法規資料庫), including each law's effective status and pending amendments.
  • Court decisions: an apex-tier subset of Judicial Yuan decisions: the Supreme Court, Supreme Administrative Court, Constitutional Court, Disciplinary Court and Intellectual Property and Commercial Court, plus Grand Chamber rulings. District and high court decisions are not included.

The data is updated periodically from the official sources. RegAI is not affiliated with the Ministry of Justice or the Judicial Yuan. Results are for research and are not legal advice.

Get started

RegAI MCP supports OAuth (OAuth 2.1, the MCP authorization standard built on OAuth 2.0), so the recommended way to connect is to sign in with your RegAI account. No API key needed.

Sign in with OAuth (recommended). Add a custom connector in your AI assistant with just https://mcp.regai.tw/mcp. The assistant opens RegAI's sign-in page (OAuth); sign in with your RegAI account (free; email code or LINE) and click Allow. Confirmed with Claude (web, Desktop, Claude Code), ChatGPT and Goose.

In Claude Code, one command (you sign in on first use):

bash
claude mcp add --transport http regai https://mcp.regai.tw/mcp

Or use an API key, for apps without sign-in support: copy your key from your account page and send it either

  • as a header: Authorization: Bearer YOUR_KEY, or
  • in the URL, for apps that only take a URL: https://mcp.regai.tw/mcp?key=YOUR_KEY

Step-by-step instructions for each app: examples/clients.md and https://regai.tw/mcp.

Then just ask, for example: 「民法第 184 條的內容是什麼？」 or "What does Taiwan's Civil Code say about tort liability? Cite the article." More in examples/prompts.md.

Security and privacy

Read-only tools over public data only. Sign-in follows the MCP authorization spec (OAuth 2.1 with PKCE); access tokens last 1 hour and refresh tokens rotate on every use, and you can disconnect any app under "Connected apps" on your account page. API keys are matched by their hash (and stored encrypted so you can view yours again); you can regenerate or revoke your key at any time. We don't log the content of your queries, only a keyed fingerprint for troubleshooting. Details: SECURITY.md and https://regai.tw/mcp/security. Privacy policy: https://regai.tw/privacy.
