Search for companies by Korean/English name, stock code, or corp code. Supports fuzzy matching: chosung search (ㅎㄷㅈㄷㅊ→현대자동차), abbreviations (삼전→삼성전자), and typo tolerance. Returns matching companies with their corp_code (needed for other tools). Examples: - query=
AI agents call opendart_search_company to retrieve information from OpenDART MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves company metadata (name, stock code, corp code) from a public financial database without creating, modifying, deleting, or executing any operations. It is a simple lookup utility that enables subsequent operations on other tools but performs no irreversible or state-changing actions itself.
From the tool's definition Tool description states it 'Search[es] for companies' and 'Returns matching companies' — a pure query operation with no side effects. The function name prefix 'opendart_search_' and verb 'search' further confirm retrieval-only behavior.
