MCP Vulnerability Scanner

A Model Context Protocol (MCP) server for scanning IP addresses for vulnerabilities. This server provides tools to perform security scanning on individual IPs or multiple IPs at once.

Features

• Scan IP addresses for vulnerabilities using multiple methods:
  • Nmap vulnerability scanning
  • API-based vulnerability checks
• Supports single IP scanning or batch scanning of multiple IPs
• Returns detailed reports with vulnerability severity, descriptions, and remediation steps
• Implements the Model Context Protocol for easy integration with MCP clients

Prerequisites

• Node.js (v14.x or higher)
• npm (v7.x or higher)
• Nmap (optional, for enhanced scanning capabilities)

Installation

1. Clone this repository:

   git clone <repository-url>
   cd mcp-vulnerability-scanner

2. Install dependencies:

   npm install

3. Install Nmap (optional but recommended):

   # For Ubuntu/Debian
   sudo apt-get update
   sudo apt-get install nmap
      
   # For CentOS/RHEL
   sudo yum install nmap
      
   # For macOS
   brew install nmap

Configuration

The MCP Vulnerability Scanner is configured through the following files:

1. .mcp.json

This is the main MCP configuration file:

{
  "name": "vulnerability-scanner",
  "version": "1.0.0",
  "description": "An MCP server for scanning vulnerabilities on IP addresses",
  "command": "npm",
  "args": ["run", "dev"],
  "capabilities": {
    "contextItemTypes": ["ip"]
  }
}

2. Integration with VS Code

For VS Code integration, the configuration is in .vscode/mcp.json:

{
  "mcpServers": {
    "mcp_vuln": {
      "command": "npm",
      "args": [
        "run",
        "dev",
        "mcp-vulnerability-scanner",
        "--prefix",
        "/path/to/mcp-vulnerability-scanner"
      ],
      "env": {
        "MCP_SERVER_PORT": "3000"
      }
    }
  }
}

Update the --prefix path to point to your installation location.

Usage Example

Below is a example showing the vulnerability scanner in action:

• Single Ip Addess scan

• Multiple Ip Addess scan

Available Tools

This MCP server provides the following tools:

1. scan-ip

Scans a single IP address for vulnerabilities.

Parameters:

• ip: The IP address to scan (string)

Example usage:

scan-ip 192.168.1.1

2. scan-multiple-ips

Scans multiple IP addresses for vulnerabilities.

Parameters:

• ips: Array of IP addresses to scan (string[])

Example usage:

scan-multiple-ips ["192.168.1.1", "192.168.1.2", "192.168.1.3"]

Deployment Options

1. Local Development

Run the server in development mode:

npm run dev

2. Build and Run in Production

npm run build
npm start

3. Docker Deployment

Create a Dockerfile in the project root:

FROM node:18-alpine

# Install Nmap
RUN apk add --no-cache nmap

WORKDIR /app

COPY package*.json ./
RUN npm ci

COPY . .
RUN npm run build

EXPOSE 3000

CMD ["npm", "start"]

Build and run the Docker container:

docker build -t mcp-vulnerability-scanner .
docker run -p 3000:3000 mcp-vulnerability-scanner

4. VS Code Extension Integration

To use this server in VS Code:

1. Configure the .vscode/mcp.json file as shown above
2. Ensure the path to the server is correctly set
3. The server will be available to MCP-enabled extensions

Security Considerations

• This scanner requires administrative/root permissions to run comprehensive Nmap scans
• Only scan IP addresses that you have permission to scan
• Be aware that vulnerability scanning might trigger security systems or IDS alerts
• The scan results are provided for informational purposes only
