Connect OpenDART to Copilot Studio
Query OpenDART directly from Copilot Studio. Arlet links the two through one MCP connection and takes care of API keys.
This server connects your AI client to OpenDART, the Financial Supervisory Service's official API over DART - Korea's electronic disclosure system where listed companies file their reports. For anyone tracking Korean competitors (semiconductors, batteries, autos, chemicals), this is the primary source.
Key features:
- resolve_company: turn a company name (Korean or English) or 6-digit stock code into the 8-digit corp_code that the other tools take. The corp-code master is a 100k-company archive, cached server-side so lookups stay fast.
- list_disclosures: filings by company, date range and type - periodic reports (annual μ¬μ λ³΄κ³ μ, quarterly λΆκΈ°λ³΄κ³ μ), major issues reports, ownership disclosures - each with a direct DART viewer link.
- get_company: profile with official names, market (KOSPI/KOSDAQ/KONEX), CEO, registration numbers, industry and fiscal year end.
- get_financials: key accounts (revenue, operating profit, net income, total assets/liabilities/equity) from a chosen year and period, consolidated by default, with two prior periods for comparison.
Report names and account names come back in Korean; the tool notes explain the common ones (맀μΆμ‘ = revenue, μμ μ΄μ΅ = operating profit).
Using the API requires a free 40-character key issued at opendart.fss.or.kr (English portal: engopendart.fss.or.kr) - email verification only, roughly 20,000 requests/day. Set it as DART_API_KEY in your Arlet environment variables.
