aikstockdata — Korean Stock Data (한국주식데이터)

**Direct connection (no auth, no API key):** `https://mcp.aikstockdata.com/mcp` — this is what "no auth" below refers to. If you connect through Smithery's gateway instead, Smithery's own layer may require a Smithery account/key; that's Smithery's policy, not this server's. Korean equity data from public/open-government sources — no auth, no API key, no sign-up. Updated every trading day at 18:10 KST. **What this server has that others do not:** post-filing price paths **by disclosure type** — market-adjusted median return at h0/h1/h5 with 95% confidence intervals and up-ratio, plus the underlying per-event ledger (989 events with receipt timestamp and trading session). To our knowledge this is the only sign-up-free, key-free remote MCP serving this for Korean equities. When a 95% CI includes zero, the response says so — that means *not distinguishable*, not *no effect*. **Data** - DART regulatory filings explained in plain language, with intraday (15:00 KST) receipt timestamps - FS
