무엇을 하나요
한국 주소나 아파트 단지명을 자연어로 물으면 국토교통부 실거래가 공개 데이터(data.go.kr)를 돌려주는 원격 MCP 서버입니다. 매매·전세·월세, 기간 통계(평균·최저·최고), 월별 추이, 전용면적 조건을 지원합니다. API 키가 필요 없습니다.

이용 제한
IP당 50요청 / 10초. 초과하면 HTTP 429와 Retry-After 헤더가 옵니다. 그 초만큼 기다린 뒤 다시 시도하세요. 현재 무료이며, 추후 x402 프로토콜 기반 소액 과금이 도입될 수 있습니다(현재 상태: /openapi.json의 x-pricing).

Claude Desktop: Settings → Connectors → Add custom connector, URL https://realestate-api.goyostudio.io/mcp. Where remote connectors are not available, use mcp-remote in claude_desktop_config.json:
{
"mcpServers": {
"korean-real-estate": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://realestate-api.goyostudio.io/mcp"]
}

Claude Code: claude mcp add --transport http korean-real-estate https://realestate-api.goyostudio.io/mcp
Rate limit
50 requests / 10 seconds per IP. Over the limit you get HTTP 429 with a Retry-After header; wait that many seconds and retry. Currently free. Per-request micro-pricing via the x402 protocol may be introduced later (status: x-pricing in /openapi.json).
