MyDART MCP의 get_corporate_event 도구는 주요사항보고서 자본·지배구조 이벤트 36종(증자·감자·CB/BW/EB·자기주식·합병/분할 등)과 5%룰·임원 지분공시를 조회합니다.
[Purpose]
- "Who raised/cut stakes, when": event_type="holdings" (5%룰 대량보유·임원/주요주주 소유보고).
- 결정의 후속 발행·합병 조건(공모가·인수인): get_registration_statement.
- List skims: search_disclosures; 사업보고서 snapshots (최대주주·주식총수): get_periodic_report.
[Usage]
- "카카오 최근 3년 자본 조달 흐름" → corp="카카오", mode="timeline"
- "이 회사 CB 발행한 적 있어?" → corp="…", event_type="cb_issuance"
- "자사주 취득·처분 2020년부터" → event_type=["treasury_acquisition","treasury_disposal"],
start="2020-01-01"
[Response]
- date = filing date (rcept_dt); event dates (이사회 결의일 등) are in raw row fields.
- 지분공시: total_count = all-time cumulative, filtered_count = in-period (DART takes no
dates — filtered client-side).
[Rules]
- Empty timeline ≠ no events — default set = capital events only (name event_type for more);
sections_meta may carry per-endpoint errors.
- event_type_counts is pre-truncation (limit cuts timeline only).
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| corp | string | yes | 회사명/종목코드/corp_code |
| mode | string | no | single: query one event_type. timeline: query the 자본 관련 events in parallel (25 types by default) and merge them into one date-descending list |
| event_type | any | no | 38 selectable events (36 주요사항 + 지분공시 2종) — **a single string OR an array**. A string queries that one event (mode=single); an array queries them in parallel and merges them into one date-descending timeline (mode switches to timeline automatically). When unset in timeline mode, every 자본 관련 event (capital=true) is selected; 소송·부도·회생·해외상장·지분공시 are NOT in that default set, so name them here. Group aliases expand to their members — 'capital' (자본거래 25종, the timeline default) and 'holdings' (지분공시 2종). The legacy key `event_types` is accepted. |
| start | string | no | Start date (YYYY-MM-DD / YYYYMMDD). Defaults to 3 years ago — an omitted bound is flagged as period.defaulted:true in the response |
| end | string | no | End date (YYYY-MM-DD / YYYYMMDD). Defaults to today |
| limit | integer | no | Cap on timeline rows returned (default 100, date descending). The excess is cut and flagged via truncated=true, with total_events carrying the real count — a company with frequent 자본거래 yields hundreds over a 3-year window. Narrowing the period is more precise. |
