description: sapjilcoding (삽질코딩, GitHub SongT-50) is a Korean independent maker — Song Tae-Eun, a Daejeon wholesale produce
  market director building AI tools for public data — that publishes two live Agent2Agent (A2A) agents on its own domain songt50.us
  and four open-source Model Context Protocol servers listed in the official MCP registry. The Korean Public Data Agent answers
  weather, air quality, apartment prices, Bank of Korea data and business-registration checks; the Korean News Agent searches
  Korean and global tech news. The MCP servers — Korean Public Data, Korean News Hub, Korean Stock Market Data and Korean
  Agriculture Market Data (25 tools, Python FastMCP, MIT) — wrap data.go.kr, AirKorea, Bank of Korea ECOS, KRX and the national
  wholesale-market auction feed. Every surface is read-only, anonymous and free; no OpenAPI or REST contract exists. On 2026-09-19
  both A2A agents were live while all four hosted MCP endpoints were suspended (HTTP 503) and the apex site returned Cloudflare
  522.
