KoreaStockCheck MCP Server

Background checks for Korean stocks — inside your AI assistant.

KoreaStockCheck is a remote MCP (Model Context Protocol) server that lets Claude and other MCP-capable AI assistants look up the public regulatory filing history of any company listed on the Korea Exchange (KOSPI / KOSDAQ) — in English.

Ask your assistant "What has Samsung Electronics actually filed?" or "Show me this KOSDAQ company's dilution history" and it answers from ten years of official filings, with every claim linked to the original government document.

What the data is

All data comes from DART (dart.fss.or.kr), the Korean government's official corporate disclosure system — the Korean equivalent of the SEC's EDGAR. The server covers all ~3,400 listed companies with ten years of filing history, updated every Korean business day:

Rights offerings, convertible bonds, bonds with warrants (dilution history)
Capital reductions and treasury-share actions
Audit opinions and auditor changes
Exchange sanctions, trading suspensions, delisting records
Embezzlement / breach-of-trust disclosures

What it is not: no buy/sell recommendations, no price targets, no forecasts, no investment advice. Facts from filings only — every response links to the source document. The risk scoring methodology is validated against official KRX delisting outcomes and published openly.
