Korean Law Mcp 🔌 MCP server Free

What it does

Korean Law MCP wraps 42 APIs from South Korea's Ministry of Government Legislation into 10 unified MCP tools, giving an AI assistant direct, structured access to statutes, court precedents, administrative rulings, ordinances, treaties and official interpretations — with built-in citation verification so the model can't fabricate a law that doesn't exist.

Tools it gives your agent

• legal_research — multi-stage research across 8 task types (full research, enforcement basis, dispute prep, amendment tracking, and more)
• legal_analysis — citation verification, case-status checks, applicable-law determination and impact mapping
• search_law / get_law_text and search_decisions / get_decision_text — statute and ruling lookup across 18 decision domains
• get_annexes — pulls schedules/forms out of HWPX, PDF, XLSX and DOCX documents as Markdown
• ordinance_radar — flags local ordinances that have fallen out of sync with amended parent legislation

Works with

Claude Desktop, Claude.ai (Pro/Max/Team/Enterprise), Claude Code, Cursor, Windsurf, Zed, VS Code and Gemini CLI, plus ChatGPT via a custom connector — any MCP-capable client.

Maintenance and safety

MIT licensed, 2.6k+ stars, 530 forks, actively versioned (v4.14.1) with documented performance work. Binds to localhost by default and requires an auth token for remote access; rate-limited to 120 req/min on the public server. All content is sourced from the official National Legal Information Center, but the project itself notes legal conclusions should be verified against original sources.

Who should use it

Developers or legal-tech teams building AI tools for the Korean market who need grounded, hallucination-resistant access to Korean statutes and case law. Note this is a domain-specific legal research tool rather than a general software-development aid.
