korea-data-mcp

English | 한국어

Pass Korean public APIs straight to an AI agent and it gets answers wrong. korea-data-mcp gives it the right ones.

An MCP server for Korean corporate filings, financials, dividends and major shareholders, stock prices, apartment sale prices and rents, business registration status, public holidays, statutes and court rulings, and Bank of Korea economic statistics, from the official free APIs of OpenDART, data.go.kr, law.go.kr and ECOS.

Correct, with evidence. 101 traps found on the live APIs (wrong half-year revenue, laws not in force yet, cancelled deals, district codes that changed in 2026, and more) are handled, each covered by a test that uses the real response. The full list is public: What korea-data-mcp handles for you. In a small evaluation, agents with korea-data-mcp answered 10 of 10 questions with one call each; with the raw APIs they hit the traps, needed about 3x the calls, and missed one.

Installs in one click. A single binary with nothing else to install. In Claude Desktop, open korea-data-mcp.mcpb and enter your keys. Also in the official MCP Registry.

Private. It runs on your machine. Your keys and questions go only to the government APIs, never through a third-party server, and there is no telemetry.

Focused. 25 tools with clear descriptions, so an agent picks the right one without filling its context with dozens of others.

News

2026-11-14 v0.1.10: entity_resolve_company identifies a company from a name or any of its numbers and returns every identifier, former names, whether it is listed now and whether the business is still active. Many companies share a name (two (주)카카오 file with DART; one closed in 2014), and DART keeps the stock codes of delisted companies, so opendart_search_companies now checks listed with each company's profile.

2026-11-11 v0.1.9: National Pension Service workplaces (datagokr_get_pension_workplaces): subscriber counts close to employee counts, unlisted companies included, with a 12-month history. Also korea-data-collect, which keeps the ownership reports and company list changes that OpenDART forgets (how).

2026-11-08 v0.1.8: Full financial statements (opendart_get_financials with scope: "full") and stakes in other companies (opendart_get_investments). Lines come in the order printed in the filing, and amounts carry their real dates, including for companies whose fiscal year ends in March or June. Investees come with their DART company code.

2026-11-04 v0.1.7: Major decisions (opendart_list_corporate_actions: rights issues, capital reductions, convertible bonds, buybacks and disposals of treasury stock, mergers and splits) and reports by 5% holders and insiders (opendart_get_ownership_reports).

2026-10-31 v0.1.6: Every financial amount comes with the period it covers. The output format changed.
