What the publisher says
From the World Business Calendar repository's README, as published. We do not edit it. Read it on GitHub
K-MCP — the Korean toolkit for AI agents
Everything an AI agent needs to actually get work done in Korea, as MCP servers: sell on Smart Store, Coupang and Cafe24; verify a business number; read a 한글 (.hwp) file; issue a tax invoice; send a KakaoTalk notice; know that 1/25 is a Sunday so VAT is due 1/26 — and ask a human before spending money.
한국에서 일하는 AI 에이전트의 필수 도구 모음. 스마트스토어·쿠팡·카페24 운영, 사업자 검증, HWP 읽기, 세금계산서, 카카오톡 알림, 세무 일정, 그리고 돈이 나가기 전 사람 승인.
Works with Claude Desktop, Claude Code, Cursor, Windsurf, n8n, and anything that speaks MCP over stdio. Every server is on npm and the official MCP Registry under io.github.groove79/*.
Servers
Bold = write tools. They are annotated destructiveHint and never run blind: by default they return a preview and wait for your OK in the chat; with an OKAGENTAPIKEY they wait for your tap on KakaoTalk.
