Escolha seu cliente

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

{
  "mcpServers": {
    "searxng": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-searxng"
      ],
      "_inferred": true
    }
  }
}

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

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "searxng": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-searxng"
      ],
      "_inferred": true
    }
  }
}

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

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "searxng": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-searxng"
      ],
      "_inferred": true
    }
  }
}

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

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "searxng": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-searxng"
      ],
      "_inferred": true
    }
  }
}

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

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "searxng",
      "command": "npx",
      "args": [
        "-y",
        "mcp-searxng"
      ]
    }
  ]
}

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

~/.config/zed/settings.json

{
  "context_servers": {
    "searxng": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "mcp-searxng"
        ]
      }
    }
  }
}

Adicione em context_servers. Zed recarrega automaticamente ao salvar.

claude mcp add searxng -- npx -y mcp-searxng

Uma linha só. Verifique com claude mcp list. Remova com claude mcp remove.

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
searxng_web_search	query: str, pageno?: int, time_range?: day\|week\|month\|year, language?: str, safesearch?: 0\|1\|2	Any web search	free (your SearXNG)
web_url_read	url: str, start_heading?: int, end_heading?: int, start_paragraph?: int, end_paragraph?: int	Clean extraction of an article	free

Custo e limites

O que custa rodar

Cota de API: Unlimited (your SearXNG instance)
Tokens por chamada: Search: 500-1500 tokens. Read: 1-10k depending on page.
Monetário: Free
Dica: Narrow queries with time_range and language — cuts both tokens and SearXNG load.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No keys needed; just SEARXNG_URL

Saída de dados: Your SearXNG instance (which in turn queries upstream engines)

Public SearXNG instances can be monitored by their operators — host your own for real privacy.
Extracted content reflects the live page — verify for critical decisions.

Solução de problemas

Erros comuns e correções

Connection refused

SearXNG not running or SEARXNG_URL wrong. curl the URL directly first.

Verificar: curl $SEARXNG_URL

Empty results for any query

SearXNG blocked by upstream engines or misconfigured. Check /search directly in browser.

Verificar: Open $SEARXNG_URL/search?q=test

web_url_read returns mostly nav junk

Some sites are JS-heavy; narrow with heading/paragraph ranges, or use a different extractor.

Alternativas

mcp-searxng vs. outros

Alternativa	Quando usar	Troca
omnisearch	You want multi-provider + AI search	Requires provider API keys
kindly-web-search	You want platform-aware full content	Still needs Serper/Tavily key unless paired with SearXNG
brave-search	You're OK with one commercial provider	Paid above the free tier
