koreanpulse

Get pinged in English the moment a 5%-rule filing or DART event hits a stock you care about.

We watch your KRX tickers in Korean and ping you in English when something material moves — foreign-holder 5%-rule disclosures, Korean activist filings, major DART events. KRX itself, ASIFMA, Wellington, Aberdeen, and Matthews Asia are all on record that the English flow off Korean primary sources is structurally inadequate. Bloomberg charges $24K/yr and still misses the front page of 전자신문. We translate, classify, and route the same data into your Discord / Telegram / inbox — or call it as MCP tools from Claude, Cursor, or your own AI agent.

🚧 Beta — queries + hosted translation are live today; watchlist polling and alert dispatch ship Q3 2026. Join the waitlist to lock in the launch rate.

2026 inflection

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.

Why people are paying attention to KRX

  • 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.

🚧 BetaSolo trial opens Q3 2026

Queries + hosted translation cache are live today. Watchlist polling, alert dispatch, seat enforcement, and per-tier retention windows ship Q3 2026. Today the only runtime-enforced difference between tiers is the monthly query cap (2K / 15K / 100K). Watchlist counts, alert-channel limits, seat caps, and archive retention are paper limits until the polling/dispatch loop lands. Join the waitlist and you keep the launch rate — no auto-charge until the workflow ships.

Pricing

Lock-in pricing — early supporters keep the launch rate. Pick the tier that matches how many tickers you'll watch and how many channels you'll want pinged once polling/dispatch ships.

What you get without a license
5 free MCP tools — raw DART surface
  • · track_korean_filings — raw DART filings, optionally translated
  • · lookup_corp_code — Korean name → DART corp code
  • · resolve_stock_code — KRX 6-digit ticker → corp entry
  • · search_korean_industry_news — etnews / 한국경제 RSS, 16 industries
  • · koreanpulse_about — server info, free vs paid tool list

No signup, no API key. Connect via https://mcp.koreanpulse.dev/mcp from ChatGPT or Claude.ai and these answer immediately.

What Solo $29/mo+ unlocks
2 paid MCP tools — classification work
  • · monitor_activist_investors — Korean activist filer match (KCGI, Align Partners, Truston, Anda, Cha, VIP, Life, Platform, ValueAct, Elliott)
  • · 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.

What the paid gate looks like in your AI client (live, 2026-05-07)

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?

Verified end-to-end against Claude.ai 2026-05-07. ChatGPT behaviour varies — its system prompt sometimes routes around the gate via web search. For the strongest paid-tool UX, use Claude.ai or the OpenAI Responses API directly.

After subscribing. Polar emails your license key (format koreanpulse_live_…) 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: "koreanpulse_live_…", 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.

By subscribing you agree to our Terms of Service and Privacy Policy. koreanpulse provides data only — not investment advice (자본시장법 §101 면제 영역).

Connect from ChatGPT or Claude.ai (no install)

Add the hosted endpoint as a custom connector. The 7 tools (DART filings, foreign-holder + activist tracking, Korean industry news) return Korean→English translated results in your existing chat — no pip install, no local config. Read-only data layer; not investment advice.

Streamable HTTP transport (single-region node, Let's Encrypt cert). Validated end-to-end against ChatGPT and Claude.ai 2026-05-06. For max privacy or self-hosting, the local stdio path below is still canonical.

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.
