Korean Law MCP Server for Claude

Safety notes

Do not treat model output, tool summaries, scenario workflows, citation checks, or amendment comparisons as legal advice.
Verify legal conclusions against official Korean legal sources and a qualified professional before using them for compliance, litigation, contracts, immigration, employment, taxation, or public guidance.
Legal APIs can return stale, partial, unavailable, mistranslated, or context-dependent results; review dates, jurisdiction, document type, article numbers, and official text.
Chain tools and scenario tools can combine many sources into persuasive narratives; require citation review before relying on generated explanations.
Remote HTTP deployments must protect API keys, rate limits, and access to legal research workflows.

Privacy notes

`LAW_OC` and any API-key delivery method must be treated as secret and kept out of repositories, shared prompts, logs, and screenshots.
Legal questions can reveal disputes, investigations, clients, employers, contracts, personal facts, regulated matters, or litigation strategy.
Queries, citations, law names, case numbers, document text, and generated legal analysis may be visible to the MCP client and model provider.
Avoid sending confidential client facts, privileged material, personal data, or non-public legal strategy through prompts or tool arguments.

Prerequisites

Node.js 20.19 or newer, matching the upstream package metadata.
Korea Law Open API key stored as `LAW_OC`.
Korean legal research context where Korea's statutes, precedents, ordinances, treaties, or interpretations are relevant.
Korean-language legal terminology familiarity or access to qualified review.
Agreement that MCP output is research support, not legal advice.

About this resource

Content

Korean Law MCP is an MCP server and CLI for Korean legal research. It wraps Korea Law Open API and related legal information sources so Claude can search statutes, retrieve law text, inspect precedents and decisions, compare amendment history, verify article citations, map article impact, and run scenario-style legal research workflows.

The package exposes korean-law-mcp for MCP clients and korean-law for CLI use. The upstream package metadata requires Node.js 20.19 or newer and the configuration examples use LAW_OC for the Korea Law Open API key.

Source Review

These sources were reviewed on 2026-06-05. Prefer the live repository, English README, package metadata, API documentation, architecture notes, server source, citation-verification source, scenario source, environment example, NPM registry metadata, and official Open API guide for current tool counts, installation requirements, API-key handling, supported domains, and rate limits.

Features

Search Korean statutes and retrieve official law text.
Search and retrieve precedents, Constitutional Court decisions, administrative appeals, tax tribunal decisions, customs interpretations, treaties, and related decision domains.
Verify legal article citations against official data to detect nonexistent laws, articles, or paragraph references.
Compare law text across dates and inspect amendment timelines.
Generate article impact maps across cited and citing legal materials.
Run scenario workflows for action basis, dispute preparation, procedures, ordinance comparison, amendment tracking, document review, and related research.
Search ordinances, administrative rules, annexes, forms, and legal-system trees.
Use the same package as an MCP server or CLI.

Installation

Install the package and configure the Korea Law Open API key:

npm install -g korean-law-mcp

Then add the MCP server to Claude or another MCP client:

{
  "mcpServers": {
    "korean-law": {
      "command": "korean-law-mcp",
      "env": {
        "LAW_OC": "YOUR_KOREA_LAW_OPEN_API_KEY",
        "LAW_API_PROTOCOL": "https"
      }
    }
  }
}

Test with low-risk lookups before using scenario workflows for real legal research, and verify the returned official source text manually.

Use Cases

Check whether a Korean legal citation exists before trusting a model-written answer.
Retrieve the current text of a statute article for research notes.
Compare how an article changed between two effective dates.
Gather statutes, precedents, interpretations, and ordinances for a Korean legal issue.
Explore which lower-level rules or ordinances may be affected by a law article.
Build an initial checklist for a Korean administrative or compliance procedure.

Safety and Privacy

Legal tooling needs a higher bar than ordinary search. Korean Law MCP can help retrieve and structure official legal information, but it cannot replace a qualified legal professional, official filing guidance, or jurisdiction-specific review. Treat all model-generated explanations as drafts and verify source text, dates, citations, and procedural details.

Do not send privileged facts, confidential client material, or sensitive dispute strategy through an MCP client unless that workflow has been approved. Keep LAW_OC secret, and avoid remote deployments that expose API keys or legal research endpoints without authentication and rate limits.
