Installieren

Wählen Sie Ihren Client

~/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
    }
  }
}

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

VS Code → Cline → MCP Servers → Edit

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

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

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

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

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

Continue nutzt ein Array von Serverobjekten statt einer Map.

~/.config/zed/settings.json

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

In context_servers hinzufügen. Zed lädt beim Speichern neu.

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

Einzeiler. Prüfen mit claude mcp list. Entfernen mit claude mcp remove.

Anwendungsfälle

Praxisnahe Nutzung: mcp-searxng

Give your AI private web search via self-hosted SearXNG

👤 Privacy-minded devs, self-hosters ⏱ ~10 min intermediate

Wann einsetzen: You don't want Tavily/Brave/Google to see every AI query.

Voraussetzungen

A SearXNG instance — docker run -p 8080:8080 searxng/searxng (see docs for config)
SEARXNG_URL env var — Set to http://localhost:8080 or your remote instance

Ablauf

Search

Search: 'mcp protocol spec 2026'. Time range last 3 months.✓ Kopiert

→ Result list
Read top result

web_url_read on the top result — give me the headings and first 5 paragraphs.✓ Kopiert

→ Markdown excerpt
Follow up

Based on that page, what's the single most important change in the spec?✓ Kopiert

→ Grounded answer

Ergebnis: Full research loop with zero third-party key exposure.

Fallstricke

SearXNG instance rate-limits or fails due to upstream engine blocking it — Rotate engines in SearXNG settings; consider running multiple instances
Self-hosted SearXNG needs periodic updates as engines change — Pin image tag and update monthly

Kombinieren mit: filesystem

Fact-check a claim against multiple sources

👤 Writers, analysts ⏱ ~10 min beginner

Wann einsetzen: You need to confirm something across a few independent sources.

Ablauf

Search

Search the exact claim phrase. Return top 10 from different domains.✓ Kopiert

→ Diverse result list
Cross-read

web_url_read on the 3 most authoritative — quote the sections that speak to the claim.✓ Kopiert

→ Quoted excerpts
Verdict

Claim: supported, contested, or false? Cite specifically.✓ Kopiert

→ Verdict with citations

Ergebnis: A cited fact-check.

Build a zero-API-key research assistant for your team

👤 Teams that won't/can't buy search API keys ⏱ ~40 min intermediate

Wann einsetzen: Everyone wants AI search but no one wants to manage Tavily keys per person.

Ablauf

Run SearXNG behind your intranet

Set up SearXNG container on the team server, point mcp-searxng at it.✓ Kopiert

→ All team AI clients search via shared instance
Test from multiple clients

Run the same query from Claude Desktop and Cursor — both should hit the same SearXNG.✓ Kopiert

→ Consistent results

Ergebnis: Team-wide AI search with one instance, no per-user billing.

Kombinationen

Mit anderen MCPs für 10-fache Wirkung

searxng + filesystem

Research and save notes

Search 'SBOM best practices', web_url_read the top 3, save a distilled memo to ./notes/sbom.md.✓ Kopiert

searxng + kindly-web-search

Stack both — kindly for platform-aware full fetches, searxng for private general search

Use searxng for the initial search; if any result is SO/GitHub, fall back to kindly for richer content.✓ Kopiert

Werkzeuge

Was dieses MCP bereitstellt

Werkzeug	Eingaben	Wann aufrufen	Kosten
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

Kosten & Limits

Was der Betrieb kostet

API-Kontingent: Unlimited (your SearXNG instance)
Tokens pro Aufruf: Search: 500-1500 tokens. Read: 1-10k depending on page.
Kosten in €: Free
Tipp: Narrow queries with time_range and language — cuts both tokens and SearXNG load.

Sicherheit

Rechte, Secrets, Reichweite

Credential-Speicherung: No keys needed; just SEARXNG_URL

Datenabfluss: 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.

Fehlerbehebung

Häufige Fehler und Lösungen

Connection refused

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

Prüfen: curl $SEARXNG_URL

Empty results for any query

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

Prüfen: 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.

Alternativen

mcp-searxng vs. andere

Alternative	Wann stattdessen	Kompromiss
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
