Korean public data API gateway. A Model Context Protocol (MCP) server that lets any MCP client discover, inspect, and call 80,000+ APIs on data.go.kr — weather, real estate, business registration, air quality, transit, and more. Built with C# and the official MCP C# SDK.

• 3 tools — search APIs by keyword, inspect parameters/response fields, call any data.go.kr API
• Automatic serviceKey injection — the API key is added to every request; never leaked to the LLM
• XML → JSON normalization — strips the response/header/body/items wrapper, returns clean JSON
• Error code mapping — translates data.go.kr error codes into Korean guidance messages the LLM can relay directly
• SSRF protection — domain whitelist limits calls to approved government hosts
• EUC-KR support — legacy encoding from older government APIs is auto-detected and converted
• Stateless — no cache, no database, no local files; every call is independent
• Stdio transport — standard MCP subprocess model via JSON-RPC over stdin/stdout
