{
  "mcpServers": {

      "args": [
        "yahoo-finance-mcp"

Abra Claude Desktop → Settings → Developer → Edit Config. Reinicie após salvar.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {

      "args": [
        "yahoo-finance-mcp"

  }
}

Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

VS Code → Cline → MCP Servers → Edit

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

Clique no ícone MCP Servers na barra lateral do Cline, depois "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {

      "args": [
        "yahoo-finance-mcp"
      ],
      "_inferred": true
    }
  }
}

Mesmo formato do Claude Desktop. Reinicie o Windsurf para aplicar.

O Continue usa um array de objetos de servidor em vez de um map.

Custo e limites

O que custa rodar

Cota de API: Yahoo's public endpoints are best-effort; no official published limit — don't hammer
Tokens por chamada: 200-2000 per response depending on depth
Monetário: Free
Dica: Cache statement queries — they update quarterly, not hourly. Avoid polling.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: None

Saída de dados: 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.

Solução de problemas

Erros comuns e correções

Empty data for ticker

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

Verificar: 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.

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