설치

클라이언트 선택

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "yahoo-finance": {
      "command": "uvx",
      "args": [
        "yahoo-finance-mcp"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "yahoo-finance": {
      "command": "uvx",
      "args": [
        "yahoo-finance-mcp"
      ],
      "_inferred": true
    }
  }
}

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "yahoo-finance": {
      "command": "uvx",
      "args": [
        "yahoo-finance-mcp"
      ],
      "_inferred": true
    }
  }
}

Cline 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "yahoo-finance": {
      "command": "uvx",
      "args": [
        "yahoo-finance-mcp"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "yahoo-finance",
      "command": "uvx",
      "args": [
        "yahoo-finance-mcp"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

{
  "context_servers": {
    "yahoo-finance": {
      "command": {
        "path": "uvx",
        "args": [
          "yahoo-finance-mcp"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add yahoo-finance -- uvx yahoo-finance-mcp

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

비용 및 제한

운영 비용

API 쿼터: Yahoo's public endpoints are best-effort; no official published limit — don't hammer
호출당 토큰: 200-2000 per response depending on depth
금액: Free
팁: Cache statement queries — they update quarterly, not hourly. Avoid polling.

보안

권한, 시크릿, 파급범위

자격 증명 저장: None

데이터 외부 송신: Queries to finance.yahoo.com (via yfinance library)

Yahoo can and does change endpoints; when the MCP breaks, update yfinance upstream.
Not for real-time trading — 15-20 min delay on most feeds.

문제 해결

자주 발생하는 오류와 해결

Empty data for ticker

Ticker symbol wrong or delisted; try the exchange-suffixed form (e.g. TSLA vs 'TSLA.BA' for BA listing).

확인: Search yahoo finance web for the ticker

429 Too Many Requests

yfinance hit Yahoo's informal limits. Back off 5 min; avoid tight loops.

ImportError on yfinance

Reinstall with uvx --upgrade — yfinance version lag is common.

확인: uvx --from ... yahoo-finance-mcp --help
