Which MCP Server Should You Choose?
Choose EdgeDepth Research when:
You need dedicated capabilities in the Finance & Fintech domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
You have access to required keys: EDGEDEPTH_API_KEY.
Returns the closed grammar registry: feature ids, types, ranges, operators, windows, sequence rules, limits, and error codes. `search`, `feature_ids` and `compact` narrow it.
list_instruments
Returns the research universe and coverage. The default is a compact summary; use `symbols: [...]` for selected full records or `full: true` for the verbatim canonical universe.
prepare_study
Free deterministic structured preparation, provenance and allowance estimate. Requires the web `/prepare` release first.
interpret_prose
Turns prose into a proposed query document. It does not execute the query. Optional `time_zone` accepts an IANA time zone for calendar planning.
run_scan
Executes a `research_query.v2` document and returns result bytes with counts, denominators, outcomes, the unconditional same-scope reference, and the reproducibility key. Projected by default (`rows`, `full_rows`, `full_counts`).
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
EdgeDepth Research is categorized under Finance & Fintech and uses a local stdio subprocess. In contrast, Koreanpulse belongs to Finance & Fintech using local stdio subprocess. Select EdgeDepth Research when you need capabilities focused on finance & fintech and Koreanpulse when you require tools for finance & fintech.
Continues a prior scan with its opaque cursor. Never construct cursors manually.
ground_screenshots
Resolves host-extracted screenshot coordinates against recorded candle closes and coverage, retaining uncertainty and deduplicating event views. Free.
investigate_move
Reads the existing lead-up and optional recorded detector geometry for a grounded event, and optionally prepares exact unrun setup documents. Free read; historical entitlement applies.
snapshot_at
Reads registry feature values, window aggregates, and fired rules as of a recorded moment.
base_rate
Counts matches and eligible buckets for one clause over a window.
commonality
Finds the deterministic intersection across multiple moments with selection-bias caveats included.
get_report
Retrieves a published report by its 8-character canonical hash.

track_korean_filings
Track 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_code
Korean 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_code
KRX 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_news
Korean 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_investors
Korean 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_holders
Monitor 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_about
Server 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.
