설치

클라이언트 선택

~/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
    }
  }
}

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

~/.cursor/mcp.json · .cursor/mcp.json

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

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

VS Code → Cline → MCP Servers → Edit

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

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

~/.codeium/windsurf/mcp_config.json

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

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

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

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

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

context_servers에 추가. 저장 시 Zed가 핫 리로드.

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

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

함정

SearXNG instance rate-limits or fails due to upstream engine blocking it — Rotate engines in SearXNG settings; consider running multiple instances

도구

이 MCP가 노출하는 것

도구	입력	언제 호출	비용
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

비용 및 제한

운영 비용

API 쿼터: Unlimited (your SearXNG instance)
호출당 토큰: Search: 500-1500 tokens. Read: 1-10k depending on page.
금액: Free
팁: Narrow queries with time_range and language — cuts both tokens and SearXNG load.

보안

권한, 시크릿, 파급범위

자격 증명 저장: No keys needed; just SEARXNG_URL

데이터 외부 송신: 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.

문제 해결

자주 발생하는 오류와 해결

Connection refused

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

확인: curl $SEARXNG_URL

Empty results for any query

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

확인: 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.

대안

mcp-searxng 다른 것과 비교

대안	언제 쓰나	단점/장점
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
