Korean Stock MCP Server — free, no authentication
Connect Claude or ChatGPT to Korean market data in about 30 seconds. Paste this endpoint as a custom connector — there is no API key and nothing to sign up for:
https://mcp.aikstockdata.com/mcpListed in the official MCP Registry as com.aikstockdata/mcp
(domain-verified). Transport is Streamable HTTP, stateless JSON-RPC.
What the AI can then do
- Look up one stock by name or 6-digit code — close, market cap, latest filings.
- Read a day's market digest: index close, advance/decline, the most material filings.
- Pull up to 250 trading days of daily closes for a stock.
- Read the earnings board and growth rankings with the formula stated in the data.
Setup
- Open your AI client's connector or integration settings.
- Add a custom MCP server with the URL above. Leave authentication empty.
- Ask something like: "Summarise the Korean stock market for the latest trading day" or "What did Samsung Electronics report most recently?"
If your client does not support MCP, you can get the same data by pasting a JSON URL into the conversation — see the endpoint list. The AI-facing summary of this site lives at /llms.txt.
Why an AI answer from this source is checkable
- Every record carries its own price date and filing cut-off, so the model can state how old the number is instead of implying it is live.
- Missing values are
null, never 0 — the model cannot mistake "no data" for "zero". - Every filing links back to the original DART document, so a claim can be traced.
- Response rules for AI are published at /llms.txt and /llms-full.txt.
What is not here
- No real-time or intraday prices. Closing prices only, published the next business day (T+1) by the government source. If you need live quotes, this is the wrong dataset.
- No PER, PBR, target prices or analyst ratings. Those are brokerage-derived; this project publishes only public-sector data.
- No investor-type flows (foreign / institutional / retail).
- No sector classification yet.
- Filing explanations are written in Korean. Field names and structure are English-friendly; the prose is not translated.
This site publishes public data as fact. It is not investment advice and does not recommend buying or selling any security. Source: Financial Services Commission open data portal (prices) and DART, the Financial Supervisory Service filing system.
