Overview

DuckDuckGo Web Search MCP Server is a project that provides a Model Context Protocol (MCP) server for searching the web using the DuckDuckGo search engine and optionally fetching and summarizing the content of the found URLs.

To use the server, you need to set it up with the uvx package manager and configure it in your MCP client (like Claude) to utilize the search and fetch functionalities.

  • Web search using DuckDuckGo. - Extracts titles, URLs, and snippets from search results. - Optional content fetching and conversion to markdown format using Jina API. - Parallel fetching of multiple URLs for faster processing. - Configurable maximum number of search results. - Graceful error handling for timeouts and other issues.
  1. Conducting web searches without needing an API key.
  2. Fetching and summarizing content from multiple URLs concurrently.
  3. Integrating web search functionality into MCP-compatible applications.

{
  "mcpServers": {
    "web-search-duckduckgo-kouui": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-web-search-duckduckgo-kouui"
      ]
    }
  }
}

Claude Desktop
