About
OpenData MCP is a Model Context Protocol server that enables AI assistants to discover, document, and call APIs from the Korean Public Data Portal (공공데이터포털 / data.go.kr). Key features of OpenData MCP: - Search available public APIs by keyword through the Korean government data portal - Automatically generate standardized OpenAPI documentation in Markdown format from search results - Execute direct HTTPS calls to OpenAPI endpoints with configurable parameters, headers, and request bodies - Automatic authentication handling with service key injection for authorized endpoints - Support for GET and POST methods with proper parameter mapping and header management The server integrates with an MCP backend at mcp.ezrnd.co.kr and requires an ODP_SERVICE_KEY environment variable for accessing authenticated Korean public datasets.

Open Data MCP
[](https://smithery.ai/server/@iosif2/opendata-mcp)한국 공공데이터포털(OpenAPI)을 더 쉽게 탐색·호출할 수 있도록 돕는 Model Context Protocol(MCP) 서버입니다. 다음과 같은 MCP 도구를 제공합니다:
listId 목록으로 표준 문서(markdown) 병합내부적으로 검색/문서 도구는 mcp.ezrnd.co.kr(HTTPS) 백엔드를 사용합니다.
요구 사항
설치
npm install
실행(개발)
Smithery CLI를 사용해 MCP 개발 서버를 구동할 수 있습니다.npm run dev
> 참고: @smithery/cli가 MCP 호스트 역할을 하며, 테스트 환경에서는 기능 미지원으로 인해 ODP_SERVICE_KEY주입이 불가능합니다
> 추후 환경변수 등으로 사전 주입하여 서버를 실행할 수 있게 수정 예정
환경변수
