koreanpulse

Korean stock disclosures, activist filings & foreign-holder flows in English — for AI agents via MCP.

Korean stock market intelligence for AI assistants. koreanpulse is an MCP server that connects ChatGPT / Claude / Cursor / FastMCP agents to Korean (KRX / KOSPI / KOSDAQ) equity data — track DART corporate disclosures as they are filed, monitor foreign investor holding changes and activist investor campaigns, and search classified Korean industry news, all in English. Data and intelligence only — not buy/sell recommendations.

The goal: get pinged in English when a 5%-rule filing or DART event hits a stock you care about. (Beta — watchlist polling + alert dispatch are planned and not yet available; what works today is on-demand queries.)

The pitch: koreanpulse translates, tags, and filters Korean primary-source disclosure data — foreign-holder 5%-rule disclosures, Korean activist filings, major DART events — for AI assistants. KRX itself, ASIFMA, and several global asset managers are on record that Korean disclosure flow into English is structurally thin. Free public daily snapshot at /today; paid Cloud tiers (Solo $29/mo, Analyst $79/mo, Desk $249/mo) unlock the two allowlist-tagging tools now — watchlist polling + alert dispatch are planned and not yet available; early subscribers keep their signup rate when those land. OSS self-host available for hackers — see Run it yourself.

For AI/MCP agent builders. koreanpulse plugs Korean equity primary sources into your existing Claude Desktop / Cursor / FastMCP agent — same MCP shape your agent already uses for US data. Three connection modes: (a) hosted remote MCP at https://mcp.koreanpulse.dev/mcp for ChatGPT / Claude.ai / OpenAI Responses API custom connectors, (b) pip install koreanpulse + 4-line config for Claude Desktop / Cursor stdio, (c) Smithery marketplace listing for Smithery CLI users. The 7 tools surface DART filings, foreign-holder 5%-rule flows, Korean activist filings, and 16-sector industry news as typed function calls; the rest of your trading-agent stack stays unchanged.

Claude.ai / ChatGPT (remote MCP). Add https://mcp.koreanpulse.dev/mcp as a custom connector in Claude.ai (Settings → Connectors), ChatGPT (Settings → Connectors or Apps SDK), or wire it directly from the OpenAI Responses API: tools=[{type: "mcp", server_url: "https://mcp.koreanpulse.dev/mcp"}]. Read-only — surfaces filings and disclosures only. No trading execution, no investment advice.

What this server answers (capability vector for agent retrieval). Korean DART (전자공시) filings on any KOSPI / KOSDAQ / KONEX / KRX ticker; 5%-rule shareholding disclosures tagged against a maintained allowlist — Korean activist filers (KCGI / Align Partners / Truston Asset / Anda Asset / Cha Partners / VIP Asset / Life Asset / Platform Partners / Must Asset Management / Dalton Investments / Flashlight Capital Partners / Oasis Management / Palliser Capital / Whitebox Advisors / City of London Investment Management + ValueAct / Elliott when filing in Korea) and global foreign holders (BlackRock / Vanguard / State Street / Fidelity / Capital Group / T. Rowe Price / Wellington / Matthews Asia / Templeton / Aberdeen / Schroders / Norges Bank / GIC / Temasek / Goldman Sachs / JPMorgan / Morgan Stanley / Citadel / Millennium / Bridgewater); Korean industry news across 16 sectors (semiconductor / shipbuilding / battery / biotech / defense / auto / EV charging / AI / steel / petrochem / construction / fintech / gaming / e-commerce / telco / energy) sourced from 전자신문 + 한국경제 + The Korea Herald (English-native) + 지디넷코리아. All with on-demand English translation cached server-side. Tool catalog and example queries are also returned by koreanpulse_about for agent-side capability discovery.

Status

Pre-alpha (v0.1.13). 7 MCP tools shipped — 5 free + 2 license-gated (activist + foreign-holder allowlist tagging, Solo $29/mo+). 433 tests pass, 1 skipped. Beta — watchlist polling + alert dispatch are planned and not yet available. Beta acquisition plan in docs/BETA.md.

Why I built this

I'm a Seoul-based developer. I kept watching English-speaking friends miss the Korean disclosure that would have flipped their KOSPI trade — KCGI filing on a value-up target, BlackRock crossing 5% on an HBM name, an activist quietly accumulating. The Korean primary source (DART 전자공시) is unambiguous; English coverage is often hours late or absent. I wanted a thing they could plug into the chat assistant they already use, ask "anything new on Samsung Electronics?", and get the same answer I'd get reading DART directly. That's koreanpulse.

I run it as MCP because that's the shape of stack the people I'd want to use this already have — Claude Desktop, Cursor, the OpenAI Responses API, ChatGPT custom connectors. No new client to install. Free tier is the daily snapshot and the five free tools; the two license-gated tools (5%-rule allowlist tagging on activists and foreign holders) are the part that takes a Korean speaker hours to do by hand.

Why this exists

"Majority of foreign investors find it surprisingly difficult to penetrate the Korean hedge fund market due to its limited accessibility and availability of information in foreign language." — HedgeVista, 2025

"Published information should be made available in both Korean and English for all investors." — ASIFMA Korean Capital Markets Report, 2022

"The Korea Exchange will provide investor relations services to companies that lack the capability, particularly in English." — Wellington Management on Korea Value-Up program, 2025

The English-IR gap is multi-source verified. The triggers below sit on top of it:

• Broker access keeps widening — Hana Securities × Futu launched Korean stock trading for Futu's Hong Kong retail customers (April 2026), and Samsung Securities × Interactive Brokers launched a pilot (May 2026)
• KOSPI has been under review for MSCI Developed Market reclassification — one reason global investors track Korean market-access changes
• IRC (Investor Registration Certificate) requirement abolished 2023-12-14, removing the decades-old registration step for foreign investors' direct KRX access
• Millennium made its first Korean allocation ($250M to Billionfold) in 2025
• Korean activist scene maturing (KCGI, Align Partners) + global activists filing in Korea (ValueAct, Elliott)
• Korean shipbuilding, HBM, defense, biotech all globally relevant — but Korean-only sourcing
• Korean retail rotated heavily out of crypto into KOSPI ($110B left Upbit/Bithumb in 2025)
• Bloomberg/FactSet enterprise tier only — indie/SMB tier empty

Pricing

🚧 Beta. Solo $29 / Analyst $79 / Desk $249. Subscribing via Polar starts a paid monthly subscription that charges immediately at checkout; a 30-day refund window applies. What a paying user receives immediately: the two license-gated allowlist-tagging tools, hosted translation, and the metered query cap (2K / 15K / 100K). Watchlist polling, alert dispatch, seat enforcement, and per-tier retention windows are planned and not yet available — until they ship, seat counts, watchlist counts, alert-channel limits, and archive-retention windows are paper limits, and most tier differentiation is roadmap. Early subscribers keep their signup rate when those features land.

Tier	$/mo	Watchlists	Queries/mo	Archive	Alert channels
Cloud Solo	29	5 (planned)	~2,000 (metered)	30 days (planned)	1 Discord or Telegram (planned)
Cloud Analyst	79	25 (planned)	~15,000 (metered)	1 year (planned)	Multi (Discord / Telegram / Email) (planned)

Run it yourself (OSS)

Source is AGPL-3.0. Self-hosters can run the MCP server locally with their own DART and OpenAI keys. This path is for hackers and max-privacy users.

	OSS self-host	Cloud (Solo / Analyst / Desk)
Cost	$0	$29 / $79 / $249 per month
Provider keys	your DART_API_KEY + your OPENAI_API_KEY	your DART_API_KEY (stays local); we hold the OpenAI key for you
Local install required	yes (pip install koreanpulse)	yes (same pip install; only translation calls hit our Worker)
Watchlist polling + alerts	not included	planned — not yet available
Hosted archive	none	planned — not yet available (30 days / 1 year / team archive)
Hosted translation cache	none	included now (cross-tenant cache hits compound)
Account sync	none	planned — not yet available
Support	community only (issues/PRs)	priority support on Analyst / Desk
Best for	hackers, privacy-strict envs, OSS contributors	anyone who'll want the watchlist-to-alert workflow once it ships

OSS self-host is not in the pricing table above — it's a separate lane. See docs/SELF_HOSTING.md for the install + key wiring. Note: the OSS-vs-Cloud table above covers the pip-install paths. There is also a zero-install path — the hosted remote MCP at https://mcp.koreanpulse.dev/mcp answers the 5 free tools (including DART filings) with no local install and no DART API key of your own; add the URL as a custom connector in ChatGPT / Claude.ai (license-gated tools take a license_key argument).

Tools

7 MCP tools shipped — 5 free + 2 license-gated. Callable from Claude Desktop / Cursor / any MCP client. The paid tier unlocks the allowlist-tagging work that takes a Korean speaker to do by hand; the free tier ships the raw DART + RSS surface.

Free tier (no license_key, no signup):

Tool	One-line
track_korean_filings	Recent DART filings + EN translation/summary
lookup_corp_code	Korean company name → DART corp code
resolve_stock_code	KRX 6-digit → DART corp entry
search_korean_industry_news	etnews / 한국경제 / Korea Herald / zdnet RSS, classified into 16 industries
koreanpulse_about	Server info, free vs paid tool list

Paid tier (Solo $29/mo+, requires license_key — pass as tool argument or via the calling client's secure-input field):

Tool	One-line
monitor_activist_investors	Activist 5%-rule filings auto-tagged (KCGI / Align / Truston / Anda / Cha / VIP / ValueAct / Elliott)
monitor_foreign_holders	Foreign 5%-rule disclosures (BlackRock / Vanguard / Norges / GIC / Temasek + 15 more)

When a paid tool is called without a license, the server returns a short notice explaining that a license key is required. No checkout link is included in the tool response.

4 more planned (docs/SPEC.md): digest_analyst_reports, get_ma_pipeline, track_government_policy, summarize_korean_earnings_call.

Differentiation vs incumbents

Differentiation vs other Korean MCP servers

A handful of Korean-data MCP servers exist. Pick what 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.

Other servers in the space (different scope or smaller install base): SongT-50/korean-stock-mcp, koreal6803/finlab-ai (quant-focused), eddmpython/dartlab (Python lib). Comparison last verified 2026-05-07 — other projects may have shipped changes since.

Capacity (DART quota math)

DART caps each API key at 40,000 calls/day (verified 2026-05). We enforce a soft cap at 32,000/day (80%) with DART_DAILY_QUOTA env override.

Filing-list responses go through list_filings_cached() with a freshness-aware TTL (60s for today's window, 1h for ≤6d old, 24h for ≥7d old). Cache hits don't burn DART quota.

Cache hit	Customer ceiling/day	MAU ceiling (12mo mix)
0% (no filing cache)	32,000	~800
70% (3-mo realistic)	107,000	~9,500
85% (mature)	213,000	~19,000
95% (high reuse)	~25,000 MAU (DART-limited)	—

Hard ceiling: ~30,000 MAU per DART key. Second key (separate 사업자등록번호) required beyond that.

Forecast 12mo mix (756 MAU) sits at ~930 DART calls/day = 2.9% of soft quota with 70% cache. ~34× headroom to scale before quota engineering.

See src/koreanpulse/cache.py, src/koreanpulse/dart.py:list_filings_cached.

Roadmap

Available now: queries (DART filings, foreign-holder + activist tracking, industry news), hosted translation cache (Cloud KOREANPULSE_CACHE_MODE=hosted), /today daily snapshot, Polar → D1 license issuance (Polar is our sole billing provider and Merchant of Record), first-party hosted MCP endpoint at https://mcp.koreanpulse.dev/mcp (Streamable HTTP transport for ChatGPT / Claude.ai / OpenAI Responses API custom connectors — no pip install).

Planned — not yet available:

• Watchlist polling loop (Cloudflare cron + koreanpulse.alerts)
• Alert dispatch enforcement (Discord / Telegram / Slack / webhook)
• Per-tier limit enforcement: watchlist count, alert-channel count, archive retention, seat count

Earlier milestones:

• W1–2 ✅ project skeleton, FastMCP server, DART client, agentprod integration
• W3–4 ✅ MVP: track_korean_filings, lookup_corp_code, search_korean_industry_news, translation layer with cache
• W5–6 ✅ Webhook handler skeleton (license auto-issuance) — Polar billing
• W5–6 ✅ Cloudflare D1-backed LicenseStore (replaces in-memory)
• W7–8 ⏳ Watchlist polling + alert dispatch (planned, not yet available) — wiring cache-worker cron + daily-worker cron + koreanpulse.alerts module into the watchlist-to-alert workflow that powers Solo / Analyst / Desk. D1 schema and alert-dispatch primitives already shipped; the cron loop is the missing piece.
• W7–8 digest_analyst_reports, summarize_korean_earnings_call
• W9–10 Multi-seat / shared watchlists for Cloud Desk
• W11–12 First paid customer

Architecture

• MCP server — FastMCP (Python), runs on the user's machine over stdio. Zero hosting cost on our side. Cloud customers still install this locally; switching KOREANPULSE_CACHE_MODE=hosted routes translation calls (only) to the Worker.
• Cache Worker (cache-worker/) — Cloudflare Workers + KV. Holds our OpenAI key, fronts a global translation cache, gates each call behind a license check. Free tier (100K req/day Workers + 100K read/day KV) covers paid traffic until well past $5K MRR.
• Daily Worker (daily-worker/) — Cloudflare Workers + KV. Cron-driven /today dashboard build (KST 16:30 weekdays).
• Webhook Worker (webhook-worker/) — Cloudflare Worker + D1 (SQLite). Handles Polar billing events (Polar is our sole billing provider, active 2026-05-06+) and /v1/validate for the Cache Worker. Replaces the old Lightsail/FastAPI/Postgres stack so the operator runs zero servers.
• Reuses agentprod — Throttle, Retry, CostTracker.

OSS self-host vs Cloud

Two ways to run the MCP, switched via KOREANPULSE_CACHE_MODE. Both require a local install (pip install koreanpulse + 4-line Claude Desktop config); the difference is whether translation calls go through our Worker or directly to OpenAI from your machine.

(Quick-start comparison also appears in "Run it yourself" above — keep both in sync when editing.)

	local (OSS self-host)	hosted (Cloud Solo / Analyst / Desk)
Local MCP install	required	required (same pip install)
Provider key	your OPENAI_API_KEY	ours, on the Worker (no OpenAI key on your side)
Translation cache	local JSONL file	global Cloudflare KV (cross-tenant reuse)
Per-call cost	OpenAI billed to you	absorbed in your Cloud plan
Privacy	translation never leaves your machine + OpenAI	translation calls go to our Worker; DART traffic still local
Best for	hackers, OSS contributors, max-privacy envs	anyone who'll want the watchlist-to-alert workflow once it ships

Cache hits are the entire reason a $29/mo Solo plan can sustain healthy gross margin: the same Korean filing title gets translated once, then served to every other tenant on the same plan from KV. See docs/CLAUDE_DESKTOP.md for the env-var split between modes.

Hosted HTTP transport (no local install). First-party endpoint at https://mcp.koreanpulse.dev/mcp (Streamable HTTP, single-region node fronted by Caddy + Let's Encrypt cert). Add as a custom connector in ChatGPT (Settings → Connectors), Claude.ai (Settings → Connectors), or wire it directly from the OpenAI Responses API. Last validated end-to-end against ChatGPT and Claude.ai on 2026-05-06 — monitor_activist_investors chains lookup_corp_code and returns Korean→English translated 5%-rule filings without any client-side install. The local stdio install path remains canonical for self-hosters and max-privacy users; the Smithery listing keeps Smithery CLI users in the discovery path.

Legal posture

• Korean news: short summaries with attribution + outbound links only, no full-text republication. Summaries are generated from public RSS feed metadata.
• DART data: retrieved via the DART open API with attribution; every item links to the original filing. Underlying filings remain subject to their own applicable rules.
• Korean broker reports: not ingested (paywalled reports excluded).
• No spatial / mapping data is used.
• Not investment advice. koreanpulse provides disclosure data, translation, filtering, and tagging. It does not execute trades and does not provide personalized buy/sell recommendations; no individualized analysis is performed. All output is general data intended for informational purposes only.
• Users should assess the licensing, data-use, and financial-services obligations that apply to their own jurisdiction and use case, especially when redistributing data downstream. Nothing in this repository is legal advice.
• Privacy + data protection: see https://koreanpulse.dev/privacy — covers Korea PIPA, EU GDPR, US CCPA. Terms of service: https://koreanpulse.dev/terms.

Billing (Polar — active provider)

Billing runs on the webhook-worker/ Cloudflare Worker + D1 (SQLite). The operator runs zero servers.

Active provider: Polar (polar.sh) — Merchant of Record since 2026-05-06. Handles VAT / sales tax / refunds / chargebacks for all subscriptions. License keys are emailed automatically on subscription.created via the webhook worker.

Lemon Squeezy: not in use. Their store application was declined on 2026-05-06; we did not appeal. No LS variant secrets are configured in production and no LS webhook deliveries are accepted. The /webhook/lemonsqueezy handler code remains in the repo only as a historical implementation reference — Polar is the sole billing provider.

See webhook-worker/README.md for the full deploy + secrets walkthrough; the short version:

cd webhook-worker
npm install
npx wrangler d1 create koreanpulse_db   # paste returned id into wrangler.toml
npm run migrate:prod                     # applies 0001_licenses.sql + 0002_pricing_v2.sql

# ── Polar (active provider) ──────────────────────────────────────────
npx wrangler secret put POLAR_WEBHOOK_SECRET    # `polar_whs_...` from Polar webhook page
npx wrangler secret put POLAR_API_TOKEN         # `polar_oat_...` (subscriptions:read scope)
npx wrangler secret put POLAR_PRODUCT_SOLO      # UUID of Cloud Solo product
npx wrangler secret put POLAR_PRODUCT_ANALYST   # UUID of Cloud Analyst product
npx wrangler secret put POLAR_PRODUCT_DESK      # UUID of Cloud Desk product

# ── Shared ───────────────────────────────────────────────────────────
npx wrangler secret put KOREANPULSE_CACHE_SHARED_SECRET   # same value cache-worker uses

npm run deploy

Endpoints (deployed to https://api.koreanpulse.dev or https://koreanpulse-webhook.<account>.workers.dev):

• GET /health → {"status":"ok"}
• POST /webhook/polar → Standard Webhooks signature verified (webhook-id / webhook-timestamp / webhook-signature), idempotent on webhook-id
• POST /webhook/lemonsqueezy → not in use (handler retained as historical reference — see Billing note above)
• POST /v1/validate → HMAC-signed by the cache-worker, validates license + atomically increments period counter

Polar events handled: subscription.created / .active / .updated / .canceled / .revoked. Auto-issues license keys, upgrades plans in place, deactivates on cancellation. License rows are tagged with metadata.provider = "polar" so the source is traceable per row.

The earlier path (Python koreanpulse-webhook FastAPI on Lightsail + Postgres) is superseded as of 2026-05-05; for operator memory it lives at docs/legacy/POSTGRES_LIGHTSAIL.md. New deploys should use the Cloudflare Worker path.

Distribution / marketplaces

Listing copy + submission checklists in docs/MARKETPLACE.md:

Beta acquisition (50 users in 30 days) plan + crypto-native channel mix in docs/BETA.md. Demo recording script in docs/DEMO.md. CI / PyPI release pipeline in docs/CI.md.

Alert primitives (library — the hosted watchlist→alert loop is not yet available)

The koreanpulse.alerts module ships the dispatch primitive that the planned watchlist workflow will use. koreanpulse.alerts.send_alert(url, title=, body=) sends to any of:

• Discord webhooks (https://discord.com/api/webhooks/...)
• Slack incoming webhooks (https://hooks.slack.com/services/...)
• Telegram bots (shortcut tg://<bot_token>/<chat_id> or full sendMessage URL)

Fire-and-forget — transport / formatting failures return AlertResult(ok=False) instead of raising, so an outage in one channel never breaks a tool call. See src/koreanpulse/alerts.py.

Example prompts

Copy-paste these into Claude.ai, ChatGPT, or any MCP client connected to https://mcp.koreanpulse.dev/mcp:

Ask Claude: "What DART filings were submitted for Samsung Electronics in the last 7 days?"

Ask Claude: "Look up the DART corp code for Kakao and show me its latest disclosures."

Ask Claude: "Any Korean semiconductor news this week from 전자신문?"

Ask Claude: "Which activist investors filed 5%-rule disclosures on KOSPI stocks this month? [license_key: YOUR_KEY]"

Ask Claude: "Show me recent foreign-holder 5%-rule filings — has BlackRock or Norges Bank crossed any thresholds? [license_key: YOUR_KEY]"

The first three prompts use free tools (no signup). The last two use the activist and foreign-holder allowlist tagging and require a Solo $29/mo license key — the server returns a short notice explaining that a license key is required if license_key is missing (no checkout link in the response).
