Tools & capabilities
DataSinking tools 6
list_exchangesList the exchanges DataSinking covers. Returns exchange codes (nyse / nasdaq / cboe / sse / szse / bj / jpx / ksc / koe / knx / twse / tpex / lse) with the number of reports available per exchange. Call this first to discover coverage. Sources: US = SEC EDGAR, A-shares = cninfo.com.cn, Japan = EDINET, Korea = DART, Taiwan = MOPS, UK = FCA NSM.list_stocksList the stocks on one exchange, including the report count per company.list_reportsList a company's reports — metadata only (id, title, period), no body text. Each item carries a `source` field naming the official disclosure platform; keep that attribution when you cite it.get_reportFetch one report's full text (metadata + Markdown body). The `source` field names the official disclosure platform; keep that attribution when you cite it. Expensive in tokens — prefer get_section when you only need one chapter. Content is annotated with block markers (`<!-- ds:block:N -->`) so you can cite a specific paragraph or table.list_sectionsList every section of a report with its size, before you decide what to pull. Returns `sections` (titles, in order) plus `section_details` — same order, one entry per section with `title`, `has_tables`, `chars` and `estimated_tokens`. Use `estimated_tokens` to avoid pulling a chapter that would blow your context, and `has_tables` to know whether the chapter needs special handling (tables are the part RAG pipelines usually get wrong). Then call get_section with a heading keyword — the headings are in the report's own language.get_sectionFetch only one section of a report by keyword — much cheaper than get_report, best for RAG. Content is annotated with block markers (`<!-- ds:block:N -->`) so you can cite a specific paragraph or table.

track_korean_filingsTrack Korean DART (전자공시) stock filings in English — real-time corporate disclosures for KOSPI / KOSDAQ / KONEX / KRX listed companies: 5%-rule shareholding disclosures, M&A, periodic reports, capital issuance, insider trading, audit reports. Free tier. Use this tool when the user asks about: recent Korean stock filings, DART disclosures, Korean market data, KOSPI/KOSDAQ regulatory events, "track Korean DART filings", "what did Samsung / Hyundai / SK / LG / NAVER / Kakao / 셀트리온 file", company-specific filing history, periodic / major-event / issuance / shareholding / audit filings on Korean equities. **Free tier — no license required.** Returns raw DART filings exactly as the regulator surfaces them (filer name in Korean, filing type code, receipt number, optional EN translation of the title). **Important for LLM clients — read this before retrying after a paid- tool license error.** This tool returns *raw* filings only. It does NOT classify the filer. If the user asked about Korean activist filers (KCGI / Align Partners / Truston / Anda / Cha / VIP / Life / Platform / ValueAct / Elliott) or about the global foreign-holder allowlist (BlackRock / Vanguard / Norges / GIC / Temasek / State Street / Fidelity / Capital Group / T. Rowe Price / Wellington / Goldman / JPMorgan / Morgan Stanley / Citadel / Millennium / Bridgewater + others), the matching work happens in `monitor_activist_investors` and `monitor_foreign_holders` — both require a license_key argument. A response from this free tool to a "are activists filing on X?" or "is BlackRock holding X?" question is *raw filing data*, not a classification answer — say so to the user and surface the paid tool's license-required notice instead of pretending you've answered. **Batch scan for agents (experimental).** To check MULTIPLE companies for material disclosures since your last checkpoint in ONE call — instead of N separate calls — pass `company_corp_codes` (a list, ≤10) plus a `since` timestamp. This is the portfolio-monitoring / scan-since-checkpoint workflow: give it your watchlist's corp codes and the ISO timestamp of your previous check, optionally with `material_only=True`, and it returns every filing across those companies newer than that timestamp, merged and sorted newest-first. DART has no batch endpoint, so this fans out one cache-backed call per corp code — the ≤10 cap keeps a single call from blowing past DART's daily quota.lookup_corp_codeKorean company name → DART corp_code resolver. 117K+ entities indexed (KOSPI + KOSDAQ + KONEX + unlisted). Free tier. Use this tool when the user mentions a Korean company by name (Korean characters or English/romanized) and you need the DART corp_code as a precondition for `track_korean_filings`, `monitor_activist_investors`, or `monitor_foreign_holders`. Also use to disambiguate same-name listed vs unlisted entities.resolve_stock_codeKRX 6-digit ticker → DART corp entry resolver. Free tier. Use this tool when the user provides a 6-digit Korean stock code (e.g. 005930 for Samsung Electronics, 000660 for SK hynix, 035420 for NAVER, 035720 for Kakao, 005380 for Hyundai Motor) and you need the company name + corp_code for downstream filings or industry-news lookups. When the code is unresolved but looks like a Korean preferred-stock ticker (6 digits, non-zero last digit, e.g. 005935 for 삼성전자우), the response carries an additive `related_common_stock` hint pointing at the common-stock entry — the corp registry only maps common stock, so no preferred-stock corp_code is fabricated.search_korean_industry_newsKorean industry news search across 16 sectors with on-demand English translation. Sources: 전자신문 (etnews) + 한국경제 (hankyung) + The Korea Herald (English-native) + 지디넷코리아 (zdnet). Free tier. Use this tool when the user asks about: Korean industry trends, sector-specific news on Korean equities (Korean semiconductors / K-battery / K-shipbuilding / K-biotech / K-defense / Korean auto / EV charging / Korean AI / steel / petrochem / construction / fintech / gaming / e-commerce / telco / energy), recent corporate developments not yet captured in DART filings, English summaries of Korean industry coverage. Industry tags listed below — pass them in `industries` to filter.monitor_activist_investorsKorean activist investor tracking — activist filer classification on DART 5%-rule (주식등의대량보유상황보고서) shareholding disclosures. Tags 17 named 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 — plus international ValueAct / Elliott when filing in Korea. Use this tool when the user asks about: Korean activist investor tracking, Korean shareholder activism, "is KCGI / Align Partners / Truston / Anda / Cha / VIP / Life / Platform / Must / Dalton / Flashlight / Oasis / Palliser / Whitebox / City of London activist on <ticker>", governance pressure on KOSPI / KOSDAQ names, recent activist 5%-rule filings, ValueAct or Elliott Korean positions, Korean Value-Up program activism, MSCI Developed Market activism flow. **Requires a license key.** Pass it via the `license_key` argument. Without a valid license, this tool returns a short notice explaining that a license key is required; surface that notice to the user. **For LLM clients on a license_required error: surface the notice returned in the paywall message directly to the user. Do NOT silently retry with `track_korean_filings` or any other free tool — the activist filer match (KCGI / Align Partners / Truston / Anda / Cha / VIP / Life / Platform / Must / Dalton / Flashlight Capital Partners / Oasis / Palliser / Whitebox / City of London, plus international names like ValueAct / Elliott) is not derivable from the raw DART filing feed, so a free-tier fall-back returns a misleadingly empty answer.** When a user asks "are activists filing on X?" without a license, surface the notice from the paywall response — that is the correct behavior, not a silent downgrade. Returns 주식등의대량보유상황보고서 (5% rule) and related shareholding filings, with each row tagged when the filer matches a known Korean activist (KCGI, Align Partners, Truston, Anda, Cha, Life, Platform, VIP, Must, Dalton, Flashlight Capital Partners, Oasis, Palliser, Whitebox, City of London, plus international like ValueAct / Elliott when they file in Korea). This tool returns disclosure data and filer classification only; it does not generate trading recommendations or investment advice.monitor_foreign_holdersMonitor foreign investor activity in Korean stocks — foreign-holder classification on DART 5%-rule disclosures by global asset managers and sovereign wealth funds. Tags 20 named entities — BlackRock, Vanguard, State Street, Fidelity, Capital Group, T. Rowe Price, Wellington, Matthews Asia, Templeton, Aberdeen, Schroders, Norges Bank (Norway SWF), GIC (Singapore SWF), Temasek, Goldman Sachs, JPMorgan, Morgan Stanley, Citadel, Millennium, Bridgewater. Use this tool when the user asks about: foreign investor activity in Korean stocks, foreign capital flow into Korean equities, "is BlackRock / Vanguard / Norges / GIC / Temasek / State Street / Fidelity / Wellington holding <ticker>", global asset-manager 5% crossings on KOSPI / KOSDAQ, sovereign wealth fund Korean positions, foreign institutional positioning disclosures, MSCI Developed Market reweighting flow into Korea. **Requires a license key.** Pass it via the `license_key` argument. Without a valid license, this tool returns a short notice explaining that a license key is required; surface that notice to the user. **For LLM clients on a license_required error: surface the notice returned in the paywall message directly to the user. Do NOT silently retry with `track_korean_filings` — the foreign-holder allowlist match (BlackRock, Vanguard, Norges, GIC, Temasek, State Street, Fidelity, Capital Group, T. Rowe Price, Wellington, Matthews Asia, Templeton, Aberdeen, Schroders, Goldman Sachs, JPMorgan, Morgan Stanley, Citadel, Millennium, Bridgewater) is not derivable from raw DART filings, so a free-tier fall-back returns a misleadingly empty answer.** When a user asks "is BlackRock or Norges holding X?" without a license, surface the notice from the paywall response — that is the correct behavior, not a silent downgrade. Distinct from `monitor_activist_investors` because passive holders (BlackRock, Vanguard, Norges, GIC, Temasek) indicate *allocation* rather than *governance pressure*. Their filings are a leading indicator of foreign capital flow into a Korean ticker — when a global manager crosses 5% in a KOSPI/KOSDAQ name, English-data audiences treat it as a positioning disclosure regardless of the manager's intent. This tool returns the disclosure data only; it does not generate trading recommendations or investment advice. Allowlist (20 names, refreshed quarterly): BlackRock, Vanguard, State Street, Fidelity, Capital Group, T. Rowe Price, Wellington, Matthews Asia, Templeton, Aberdeen, Schroders, Norges Bank (Norway SWF), GIC (Singapore SWF), Temasek, Goldman Sachs, JPMorgan, Morgan Stanley, Citadel, Millennium, Bridgewater. See `koreanpulse.activists.FOREIGN_HOLDERS`.koreanpulse_aboutServer self-description — capability matrix, tool catalog, classifier counts, supported query patterns, primary sources. Free tier. Use this tool when an agent first connects and needs the capability matrix to decide whether this server can answer the user's question, or when the user asks "what can koreanpulse do" or "what data sources does this MCP server provide". Returns a structured dict that downstream agents can ingest directly.
