Korean Law MCP Server: Setup for Claude, Cursor and Other Apps
Lets Claude, Cursor and other assistants search Korean statutes, court decisions and ordinances, and check legal citations in an answer.
This is a community server by chrisryugj, not run by the Korean government. It wraps the Ministry of Government Legislation (법제처) Open API, and you can use the author's hosted server or run it on your computer.
Get a free Open API key (OC) from the ministry. Local installs need it, and the hosted server works without it under a shared limit. For anything that needs legal force, check the original text at the National Law Information Center.
Good for
- Lawyers and legal staff who need Korean statutes and precedents at hand
- Public officials who track ordinances and amendments
- Anyone checking that an AI answer cites real Korean law

low risk · 4 things to watch
Low risk
It only looks up public legal texts and does not change anything. If you use the hosted server, your questions and key go through the author's server.
What it can do
- Read your data
- Create and change things
- Delete things
- Read-only mode
Watch out for
The hosted option sends your queries to the author
The public server at mcp.gomdori.app runs on the author's infrastructure, and your key goes in its address or header. Run it locally if the questions are sensitive. github.com
A key in the address can end up in logs
The README says the ?oc= key in the hosted address leaks into proxy access logs, and offers an apikey header instead. The key is free and personal, but prefer the header. github.com
Keys are personal
The README says each user must get their own key and may use it only for themselves. Do not share one key across a team. github.com
Not legal advice
The README says to check the original text at the National Law Information Center for anything that needs legal force. github.com
Security advisories
No published security advisories as of Nov 1, 2026.

Questions
Is this an official government server?
No. It is a community project by chrisryugj that uses the Korean Ministry of Government Legislation Open API. It is not published by the ministry.
Do I need an API key?
A local install needs one (LAW_OC), free from open.law.go.kr. The hosted server works without a key on a quota shared by all keyless users; adding your own key with ?oc= or an apikey header bypasses that limit, per the README.
Should I use the hosted or local server?
Hosted needs nothing installed and works in Claude.ai, VS Code and Cursor. Local keeps your questions on your machine and needs Node.js and your own key.
What is the Korean Law MCP server URL?
It is https://mcp.gomdori.app/law, and you can add ?oc= and your key at the end. This is the author's hosted server.
Can it check whether an AI answer cites real law?
Yes. The analysis tool has a mode that checks that cited articles and precedents exist and that article titles match.
Does it work in English?
The tools and the legal data are Korean. The project has an English README for setup, and the tool descriptions in the source are written in Korean.
