Summary
Wraps South Korea's OpenDart financial disclosure API to pull fundamental stock data directly into your LLM workflow. The server crawls and caches corporate filings, financial statements, dividend information, and ownership disclosures from the official Korean securities registry. Built with FastMCP and designed to deploy on Cloud Run with service account authentication. You get eight domain-specific parsers covering everything from quarterly financials to material fact reports and registration statements. The author tests it with Gemini CLI using natural language queries like "show me Samsung's 2024 financials" or "what's the recent dividend trend." Useful if you're building Korean market analysis tools or need programmatic access to DART data without wrestling with the raw API yourself.
