When KCGI or Elliott files a 5%-rule disclosure on a Korean stock, your AI assistant sees it in English — tagged, not raw.

koreanpulse is a hosted MCP server that tags Korean DART filings by known activist investors (KCGI, Align Partners, Elliott, ValueAct, Truston, Anda, Cha, VIP…) and global foreign holders (BlackRock, Vanguard, Norges Bank, GIC, Temasek…) — translated to English, callable from Claude.ai, ChatGPT, or Cursor in one click.

DART publishes activist 5% disclosures in hours, but the raw feed is Korean text with no entity tagging. Identifying whether a filing is KCGI or a passive retail holder requires a maintained Korean-name allowlist and filer-of-record disambiguation that the raw API does not provide. That classification is what koreanpulse ships.

The same endpoint also surfaces foreign 5%-rule entries whose filer matches a maintained list of sovereign wealth funds, global asset managers, and hedge funds. koreanpulse translates, tags, and filters the primary-source DART feed and links every item to the original filing — inside your AI workflow.

1-click connect. Add https://mcp.koreanpulse.dev/mcp as a custom connector in ChatGPT or Claude.ai — no npx install, no JSON config, no local secrets, no DART API key needed for the 5 free tools.

Beta — activist + foreign-holder tagging and DART queries work now. Watchlist polling and alert dispatch are planned and not yet available.

Why people are paying attention to KRX

• The activist signal is in the filing, but the entity is not. DART 5%-rule filings name the filer in Korean only. Whether “국내투자자” is KCGI building a position or a retail investor crossing a reporting threshold is not labelled anywhere in the raw feed. koreanpulse maintains the allowlist and disambiguates on every pull.
• English IR gap is structural. KRX itself, ASIFMA, Wellington, Aberdeen, Matthews Asia all on record: Korean disclosure flow into English is structurally inadequate. We are anchored on this gap.
• Real-time on-chain-style disclosures. DART publishes activist 5% filings, insider trades, and major decisions in hours. Closer to a blockchain explorer than to quarterly 10-Qs.
• MSCI Developed Market reclassification path. Korea has been under review for reclassification — one of the reasons global investors track Korean market-access changes.
• K-themes are global themes. HBM, EV batteries, K-defense, K-biotech, K-content, shipbuilding — same trades you already follow on US tape, with different microstructure and faster filings.
• Disclosure-driven market. Korean small/mid caps are heavily covered by retail flow that reacts to DART disclosures — reading the filing itself, fast, matters more here than in most markets.

How koreanpulse compares

There are a handful of Korean-data MCP servers in the wild. Pick the one that matches your job. We focus on English-first equity data with allowlist-based filer tagging, served as a hosted endpoint your LLM client can connect to in one click. If you need raw KRX OHLCV or Korean-language financial statement tables, others do that better.

Comparison last verified 2026-07-19 — other projects may have shipped changes since. Other servers in the space: OldTemple91/korea-filings-api (English summaries, pay-per-call), SongT-50/korean-stock-mcp, koreal6803/finlab-ai (quant-focused), eddmpython/dartlab (Python lib). The MCP-server space for Korean equities is shaped by the underlying data scope, not by any one team — pick what fits your workflow.

Where official English disclosure ends. KRX's mandatory English-disclosure regime reaches only the largest listed issuers; most KOSDAQ and small/mid-cap filings have no official English version. koreanpulse translates the DART feed itself, so English coverage does not stop where the mandate does.

Pricing

Solo $29/mo unlocks the two allowlist-tagging tools (activist + foreign-holder) now. Subscribing via Polar starts a paid monthly subscription that charges immediately at checkout. Watchlist polling and alert dispatch are planned and not yet available — early subscribers keep their signup rate when those features land.

`monitor_activist_investors` requires a license key. Pass a
`license_key` argument when calling this tool. The activist /
foreign-holder allowlist tagging runs server-side on the hosted
koreanpulse service. OSS self-host (github.com/whdrnr2583-cmd/
koreanpulse + your own DART API key) is free but does NOT include
this allowlist tagging, so self-hosting will not unlock this tool.

Cloud licenses work on the hosted endpoint (no install) or with the local stdio install; hosted translation uses our OpenAI key and validates your license, so no OpenAI key is needed on your side. Enterprise / SLA: contact us.

By subscribing you agree to our Terms of Service and Privacy Policy. koreanpulse provides disclosure data, translation, filtering, and tagging only — not investment advice. It does not execute trades or provide personalized buy/sell recommendations.

What runs under the hood

7 MCP tools split into 5 free (raw DART + RSS surface, no signup) and 2 license-gated — 5%-rule foreign-holder and Korean activist filer matching against a maintained allowlist. Calling a gated tool without a license returns a clear license-required notice (shown above), never a silent failure.
