Sayou Opendart Mcp
Pull Korean corporate filings and OpenDART disclosure data into Claude Code or Cursor while researching markets, competitors, or investment themes.
Overview
sayou-opendart-mcp is an MCP server for the Idea phase that lets coding agents call the OpenDART API for Korean corporate disclosure research.
What is this MCP server?
- Stdio MCP server (v0.0.6) exposing OpenDART API through agent tool calls
- Requires DART_API_KEY—register at the Korean financial disclosure (OpenDART) developer portal
- PyPI package identifier sayou-opendart-mcp for local stdio wiring
- Suited for due-diligence prompts, competitor financial context, and automated disclosure lookups
- MCP integration—not a packaged analysis skill; you still shape queries and interpret filings
- Server schema version 0.0.6 on PyPI package sayou-opendart-mcp
- Transport: stdio only in published server.json
- 1 required secret environment variable: DART_API_KEY
What problem does it solve?
Researching Korean listed companies means leaving your agent workflow to hunt filings on OpenDART by hand.
Who is it for?
Solo builders doing Korea-focused market research, competitor financial checks, or disclosure-backed validation before they build.
Skip if: Teams that need no API keys, non-Korean-only markets without DART, or institutional trading stacks with their own data vendors.
What do I get? / Deliverables
After you add DART_API_KEY and register the stdio server, your agent can fetch OpenDART-backed data inside the same thread where you write notes and specs.
- Registered stdio MCP server entry pointing at sayou-opendart-mcp
- Agent-callable OpenDART API operations for research prompts
- Repeatable disclosure lookups without manual DART portal tab switching

Journey fit
Canonical shelf is Idea because OpenDART is primarily used to research listed companies and regulatory disclosures before you commit to a product or positioning bet. Research is where solo builders query filing history, financial statements, and issuer metadata instead of manually browsing the DART portal.
How it compares
OpenDART MCP bridge, not a prebuilt equity research skill or spreadsheet product.
