ratduck-search-mcp

An MCP server that gives an agent the open web: DuckDuckGo search, URL scraping, and result filtering and ranking. No API key, no headless browser, and no npm registry — it installs straight from this page.

Install

curl -fsSL https://dixonsolutions.github.io/ratduck-search-mcp/install.sh | bash

Or point npm at the tarball yourself:

npm install -g https://dixonsolutions.github.io/ratduck-search-mcp/ratduck-search-mcp-latest.tgz

Use it

Claude Code:

claude mcp add ratduck -- ratduck-search-mcp

      "command": "ratduck-search-mcp"
    }
  }
}
