[!WICHTIG] DuckDuckGo Search MCP unterstützt den Model Context Protocol (MCP)-Standard und ist daher mit verschiedenen KI-Assistenten und -Tools kompatibel.

✨ Funktionen

[!WICHTIG] Im Gegensatz zu vielen Suchtools führt dieses Paket tatsächliches Web Scraping durch, anstatt begrenzte APIs zu verwenden, und liefert Ihnen umfassendere Ergebnisse.

Related MCP server: webmcp

🚀 Schnellstart

npx -y @oevortex/ddg_search@latest

[!TIP] Dadurch wird die neueste Version des MCP-Servers direkt und ohne Installation heruntergeladen und ausgeführt – perfekt für die schnelle Verwendung mit KI-Assistenten.

🛠️ Installationsoptionen

npm install -g @oevortex/ddg_search

Global ausführen:

ddg-search-mcp

git clone https://github.com/OEvortex/ddg_search.git
cd ddg_search
npm install
npm start

🧑‍💻 Befehlszeilenoptionen

npx -y @oevortex/ddg_search@latest --help

[!TIP] Verwenden Sie das Flag --version, um zu überprüfen, welche Version Sie ausführen.

🤖 Verwendung mit MCP-Clients

[!WICHTIG] Die gängigste Verwendungsmethode für dieses Tool ist die Integration mit MCP-kompatiblen KI-Assistenten.

Fügen Sie den Server zu Ihrer MCP-Clientkonfiguration hinzu:

{
  "mcpServers": {
    "ddg-search": {
      "command": "npx",
      "args": ["-y", "@oevortex/ddg_search@latest"]
    }
  }
}

Oder bei globaler Installation:

{
  "mcpServers": {
    "ddg-search": {
      "command": "ddg-search-mcp"
    }
  }
}

[!TIP] Starten Sie Ihren MCP-Client nach der Konfiguration neu, um die Änderungen zu übernehmen.

`query`	Yes	The search query or question.
`backend`	No	AI backend when mode="ai": "iask" or "monica". Ignored in web mode.	iask
`iaskMode`	No	IAsk mode when backend="iask": "question", "academic", "forums", "wiki", or "thinking". Default: "thinking".	thinking

TDQS

A4.2/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, so the tool is inherently read-only. The description adds behavioral context: what each mode returns (titles/URLs/snippets vs. AI answer), default backends, and that mode can be chosen. No contradictions; description supplements annotations well.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise—two short sentences. It is front-loaded with the primary action and uses line breaks for readability. Every phrase adds value; no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description adequately covers return types per mode. It mentions key parameters (mode, backend) but omits mentioning 'numResults' for web mode or 'iaskMode'/'detailLevel' for AI mode. However, since the schema provides full descriptions and the tool is simple, completeness is high but not perfect.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds minimal parameter semantics beyond the schema, only noting the default value for 'backend'. It does not elaborate on 'numResults', 'iaskMode', or 'detailLevel', but the schema descriptions are already sufficient. Hence score 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Search the web.' It distinguishes two modes with specific outputs: 'mode="web" for standard DuckDuckGo results (titles, URLs, snippets)' and 'mode="ai" for AI-generated answers'. This provides a specific verb (search) and resource (web), and differentiates the major modes effectively.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly tells when to use each mode: 'Use mode="web" for standard DuckDuckGo results' and 'Use mode="ai" for AI-generated answers'. It also provides guidance on backend selection for AI mode. With no sibling tools, no explicit when-not is necessary, but the guidance is clear and actionable.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4/5.0

Scored 2026-07-13 04:00 across 1 tool

Disambiguation5/5

Only one tool exists, so there is no possibility of confusion between tools. The two modes are clearly described within the single tool.

Naming Consistency5/5

With a single tool named 'web-search', the naming is self-consistent and follows a clear verb-noun pattern.

Tool Count2/5

A search server with only one tool feels too thin for the domain. Typically, separate tools for different search types (web, images, news, etc.) would be expected.

Completeness2/5

The single tool covers web and AI search but misses common search categories like images, news, and video, leaving notable gaps for typical search use cases.
