What Is K Public Data MCP? — A Server That Connects Korean Public Data to AI

K Public Data MCP is an open-source MCP (Model Context Protocol) server that unifies South Korea's scattered public data APIs — the Ministry of Government Legislation's law database, the DART corporate disclosure system, and the public data portal — so that "search the Civil Act," "show Samsung's financials," or "find pharmacies in Gangnam" work directly in an AI chat. It runs on a single connector URL, with no API key issuance or installation required.

What Data Can It Query?

From the national law information center: 21 tool families covering statutes, court precedents, Constitutional Court decisions, statutory interpretations, administrative rules, local ordinances, and treaties — including specialist tools like three-way comparison (act / decree / regulation) and old-vs-new clause comparison for amendments.

From DART: five tools for disclosure filings, company profiles, full financial statements, and key accounts like revenue and operating profit. From the public data portal: eight everyday datasets — pharmacies, hospitals, veterinary clinics, stock dividends, rare medicines, health supplements, and business-registration verification. For comparative law research, US (CourtListener) and German (OpenLegalData) case search is included.

Why It Was Built — the Problem of Scattered Public Data

Korean public data is already open. The problem is that every agency has different API key procedures, authentication, and response formats. Querying a statute meant learning the legislation API; financials meant DART; pharmacies meant the data portal. Wrapping these behind one MCP layer lets AI call every source the same way.

How to Start — One URL, One Minute

Register a single connector URL under Settings → Connectors in the Claude app and you're done — no API keys, no installation. Claude Desktop and Cursor take one line in a config file; it also connects as a ChatGPT custom GPT. A minute later, "find Supreme Court precedents on unfair dismissal" just works.

Where It's Actually Used

Legal work leads. In a law-firm assistant system, the MCP verifies statute and precedent citations in AI-drafted documents — a safety net against fabricated case numbers going out the door. For corporate analysis it pulls financial statements and disclosures; for transactions it verifies a counterparty's business registration in one chat line.

Public data was always there — just behind walls of API keys and documentation. One AI-readable wrapper turns it into everyone's data. What SH Consulting does in AX is essentially the same job: opening the data an organization already has into a form AI can use.
