MCP tools

1) search_financial_company(query, page=1, size=20, top_group="020000")

  • 금융회사 검색 (회사코드 조회용)
  • 권장 사용: 먼저 회사 검색 → company_code 확보 → 상품 툴 정밀 조회

2) search_savings(query=None, company_code=None, page=1, size=20, top_group="020000", all_groups=False)

  • 적금 상품 조회 (savingProductsSearch)
  • query는 내부적으로 financeCd로 매핑됨
  • company_code 지정 시 query보다 우선
  • all_groups=True면 은행(020000)+저축은행(030300) 통합 조회

3) search_deposits(query=None, company_code=None, page=1, size=20, top_group="020000", all_groups=False)

  • 정기예금 상품 조회 (depositProductsSearch)
  • query/company_code 우선순위는 위와 동일
  • all_groups=True면 은행(020000)+저축은행(030300) 통합 조회

4) search_pension_saving(query=None, company_code=None, page=1, size=20, top_group="020000", all_groups=False)

  • 연금저축 상품 조회 (annuitySavingProductsSearch)
  • 기본: all_groups=Falsetop_group 단일 조회
  • 통합: all_groups=True → 보험(050000)+금융투자(060000) 병합 조회 (중복 제거)

5) search_mortgage(query=None, company_code=None, page=1, size=20, top_group="020000")

  • 주택담보대출 상품 조회 (mortgageLoanProductsSearch)

6) search_jeonse(query=None, company_code=None, page=1, size=20, top_group="020000")

  • 전세자금대출 상품 조회 (rentHouseLoanProductsSearch)

7) search_personal_loan(query=None, company_code=None, page=1, size=20, top_group="020000")

  • 개인신용대출 상품 조회 (creditLoanProductsSearch)

top_group(권역코드) 참고

  • 020000: 은행
  • 030200: 여신전문
  • 030300: 저축은행
  • 050000: 보험
