Taiwan Legal Knowledge Base

Give your AI assistant more knowledge

Legal MCP + Claude, ChatGPT, ...

Create a free RegAI account

RegAI combines large language models — no setup required, ready to use right away. But if you're already used to AI assistants like Claude or ChatGPT, RegAI also offers an MCP (Model Context Protocol) service that gives the AI assistant you already use instant access to Taiwan's legal knowledge base.

RegAI offers an MCP server you can connect to AI assistants like Claude and ChatGPT, so they can look up Taiwan's legal knowledge base — including statutes and court decisions — while answering your questions, for answers that are more accurate and better grounded.

Service address
https://mcp.regai.tw/mcp
OAuth: connect by signing in (recommended)

RegAI MCP supports OAuth. To add it as a custom connector in your own AI assistant, just paste the service address above: the assistant opens RegAI's sign-in page; sign in and click Allow, and you're done. No API key needed.

Confirmed to work: Claude (web, Desktop, Claude Code), ChatGPT, Goose.

You can disconnect an app at any time under "Connected apps" on your account page.

Another way: an API key

If your app doesn't support signing in, use an API key instead. Sign in with an email one-time code to get one, no password.

Recommended: if your app supports custom headers, send the key in a header:

Authorization: Bearer YOUR_KEY

If your app only takes a URL, append ?key=YOUR_KEY

For example:

https://mcp.regai.tw/mcp?key=YOUR_KEY

For how keys, access and logging are protected, see Security →

What is MCP

Don't see your app here? Most MCP-capable assistants just need this same address https://mcp.regai.tw/mcp pasted into their own connector or MCP settings: apps that support sign-in open RegAI's sign-in page by themselves; for the others, add the header Authorization: Bearer YOUR_KEY, or add ?key=YOUR_KEY to the end of the address. Menus can shift slightly between app updates — if yours looks different, look for MCP or Connector settings inside that app.
