When KCGI or Elliott files a 5%-rule disclosure on a Korean stock, your AI assistant sees it in English — classified, not raw.
koreanpulse is a hosted MCP server that classifies 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, available today 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 from sovereign wealth funds, global asset managers, and event-driven hedge funds — the kind of filing that signals a position change before it hits English-language news. Bloomberg charges $24K/yr and still misses the front page of 전자신문. koreanpulse routes the same primary-source data to your AI workflow at a fraction of the cost.
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 classification and DART queries are live today. Watchlist polling and alert dispatch ship Q3 2026.
Ask Claude.ai: "What activist filings appeared on Samsung Electronics in the last 7 days?"
koreanpulse returned 2 filings:
1. Samsung C&T (028260)
Filer: 국민연금공단 — classified as PASSIVE (National Pension Service)
Type: 주식등의대량보유상황보고서 (일반)
→ "Report on Large Holdings of Stocks, Etc. (General)"
Filed: 2026-05-04 | Stake change: 9.81% → 10.02%
2. Samsung Electronics (005930)
Filer: Ha Ji-hoon — classified as ACTIVIST (independent)
Type: 임원ㆍ주요주주특정증권등소유상황보고서
→ "Report on Ownership of Specific Securities by Officers / Major Shareholders"
Filed: 2026-04-29
The raw DART feed lists both as the same filing type.

Foreign retail just got direct access to KRX
- 2025-12: IRC (Investor Registration Certificate) abolished — foreign account openings accelerated 3–4×.
- 2026-04 (last week): Hana Securities × Futu Securities (3.3M HK fintech retail) launched Korean stock trading.
- 2026-05-04 (yesterday): Samsung Securities × Interactive Brokers (4.6M global retail) pilot launched. Same day: foreigners net-bought a record 3.9 trillion KRW (~$2.7B) on KOSPI+NXT.
- ~7.9M foreign retail accounts now have a wired path into Korean equities — up from ~0 two years ago.
Sources: FSC, KRX Data, Korea Times, KED Global, 주간한국. The English-language data layer for this audience is what koreanpulse ships.
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 sits on the watchlist. Foreign capital inflow expected if upgraded. The mid-curve window opens before the headline trade.
- 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.
- Crypto-grade volatility, equity-grade infra. KOSPI / KOSDAQ small-mid caps move 10–30% on a single filing. T+2 settlement, low fees, retail-accessible.
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 intelligence with named-entity classification, 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.

monitor_foreign_holders— global allowlist match (BlackRock, Vanguard, Norges, GIC, Temasek, State Street, Fidelity, Capital Group, T. Rowe Price, Wellington, Goldman, JPMorgan, Morgan Stanley, Citadel, Millennium, Bridgewater + others)
These two classifications are not derivable from the raw DART feed — they require a maintained allowlist + Korean-name normalisation + filer-of-record disambiguation. That work is what your $29/mo pays for.
When a Claude.ai or ChatGPT user asks "what activist filings happened on Samsung Electronics this week?" without a Koreanpulse license, the hosted endpoint refuses to fall back silently. Claude.ai renders this verbatim:
I need a Koreanpulse license to identify activist investor filings on Samsung Electronics. The monitor_activist_investors tool that identifies known activist filers (KCGI, Align Partners, Truston, Anda, VIP, Cha, Life, Platform, ValueAct, Elliott, etc.) is a paid-tier feature ($29/mo Solo plan). This classification work isn't available from raw DART filings alone. To subscribe: https://buy.polar.sh/polar_cl_ETpLepEvpGkGBXAOJjQhi7gwizO8GkOW3YaHw4IgHAr Once you have a license key, I can fetch Samsung Electronics' recent activist filings from this week. Would you like to sign up?

After subscribing. Polar emails your license key (format kp_…) to the checkout email. Pass it as a tool argument when calling monitor_activist_investors or monitor_foreign_holders in Claude.ai, ChatGPT, Cursor, or the OpenAI Responses API — e.g. {license_key: "kp_…", ticker: "005930"}. Stdio env-var fallback (KOREANPULSE_LICENSE_KEY) and one-time HTTP Bearer config ship after the first paid signup; for now, include the key per-prompt or in your client's system prompt.
Annual billing −20% at launch. Cloud customers still install the local MCP (one `pip install` + 4-line Claude Desktop config); the Cloudflare Worker holds our OpenAI key and validates your license, so no OpenAI key is needed on your side. Enterprise / SLA: contact us.

Run it yourself (OSS)
Source is AGPL-3.0. Self-hosters can run the MCP server locally with their own DART and OpenAI keys — community support only, no hosted archive, no shared translation cache, no alerts. This path is for hackers and max-privacy users; the paid Cloud tiers above are what designed to ship you the watchlist-to-alert workflow once polling/dispatch lands (Q3 2026).
What runs under the hood
7 MCP tools split into 5 free (raw DART + RSS surface, no signup) and 2 paid — the classification work that takes a Korean speaker by hand (5%-rule foreign-holder + Korean activist filer matching). ChatGPT and Claude.ai render the inline subscription link automatically when a paid tool is called without a license.
