Korea Data Suite — MCP server

An MCP server that exposes Korea Data Suite as tools, so AI agents (Claude Desktop/Code, Cursor, …) can query Korean public data directly: public holidays & business-day math, and normalized MOLIT real-estate transactions (apartment/officetel/land; sale/jeonse/monthly-rent).

Tools

• get_holidays(year, month?) — Korean public holidays (incl. substitute/temporary)
• check_holiday(date) — is a date a holiday / business day?
• add_business_days(date, days) — add N business days (skips weekends & holidays)
• count_business_days(start, end) — business days in a range
• list_real_estate_regions() — LAWD region codes
• get_real_estate_transactions(region, property_type?, trade_type?, date_from?, date_to?, limit?, cursor?)
