Connect OpenDART to Codex

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 사업보고서, quarterly 분기보고서), 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 (매출액 = revenue, 영업이익 = 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.
