DNStwist MCP Server: Seamless Integration for Security Research and Analysis in AI Workflows

Overview: What is DNStwist MCP Server?

The DNStwist MCP Server is a specialized server that integrates with the Model Context Protocol (MCP) to provide advanced domain analysis services. It leverages the power of dnstwist, a robust DNS fuzzing tool designed for security research and monitoring. DNStwist MCP Server enables AI applications like Claude Desktop, Continue, Cursor, and others to perform comprehensive domain analysis, ensuring that users can identify potential threats such as typosquatting, phishing, or corporate espionage.

🔧 Core Features & MCP Capabilities

Advanced Domain Analysis

• Domain Fuzzing: Generate a wide range of domain permutations for thorough security assessments.
• Registration Check: Verify if permutated domains are registered and potentially available for exploitation.
• DNS Analysis: Perform checks on A, AAAA, MX, and NS records to identify any inconsistencies or threats.
• Web Presence: Capture HTTP banner information to gain insights into the existence of web assets behind a domain.
• WHOIS Data Retrieval: Retrieve registration dates, domains' owners, and registrar information for detailed analysis.
• Phishing Detection: Generate fuzzy hashes of web pages to detect potential malicious content.

Configurability

• Customizable Parameters: The server supports a variety of parameters tailored for different security needs, including the number of threads for parallel processing, output format preferences, and more.
• Flexible Input/Output Formats: Support for JSON, CSV, and list outputs makes it easy to integrate with other tools and workflows.

Security & Performance Considerations

• Rate Limiting and Compliance: The server is designed to respect rate limits and policies of the DNS servers being queried, ensuring sustainable use.
• Ethical Use Guidelines: Users are advised to comply with ethical research practices by only analyzing domains they own or have explicit permission to test.

🚀 Getting Started with Installation

Quick Start Guide

Installing via Smithery

To install DNStwist for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @burtthecoder/mcp-dnstwist --client claude

Installing Manually

1. Install Docker
   • macOS: Install Docker Desktop
   • Linux: Follow the Docker Engine installation guide
2. Install the Server Globally via npm

npm install -g mcp-dnstwist

3. Add to Your Claude Desktop Configuration File

{
  "mcpServers": {
    "dnstwist": {
      "command": "mcp-dnstwist"
    }
  }
}

Configuration file location:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

4. Restart Claude Desktop

Alternative Setup (From Source)

If you prefer to run from source or need to modify the code:

1. Clone and Build

git clone <repository_url>
cd mcp-dnstwist
npm install
npm run build

2. Add to Your Configuration File

{
  "mcpServers": {
    "dnstwist": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-dnstwist/build/index.js"]
    }
  }
}

💡 Key Use Cases in AI Workflows

Real-Time Threat Detection

• Use Case Scenario: Real-time monitoring of corporate websites and brand names to quickly identify any domain name manipulations or threats.
  • Technical Implementation: Integrate DNStwist with an MCP client like Claude Desktop, ensuring real-time analysis for immediate threat response.

Phishing Prevention

• Use Case Scenario: Automating the detection of phishing attempts by using DNStwist's fuzzy hash generation to compare against known malicious URLs.
  • Technical Implementation: Utilize the WHOIS data and web presence checks provided by DNStwist to build a robust phishing prevention system.

🛠️ Advanced Configuration & Security

Troubleshooting Common Issues

1. Docker Issues

   • Verify Docker is installed and running:

     docker --version
     docker ps
     

   • Check Docker permissions: Ensure your user has permissions to run Docker commands, and if on Linux, add sudo or join the docker group.
