Package Exports

mcp-nmap-server
mcp-nmap-server/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mcp-nmap-server) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

MCP NMAP Server

A Model Context Protocol (MCP) server that enables AI assistants to perform network scanning operations using NMAP. This server provides a standardized interface for AI models to interact with NMAP, making it possible to perform network analysis and security assessments through AI conversations.

Prerequisites

Windows operating system
Node.js (v18 or higher)
NMAP installed and accessible from Windows command line
TypeScript for development

Installation

Install the package globally using npm:

npm install -g mcp-nmap-server

Or install locally in your project:

npm install mcp-nmap-server

Features

The server provides access to NMAP's core functionality through a simple interface. It supports quick scans, full port scans, version detection, and custom timing templates. The implementation uses NMAP's native command-line interface, ensuring reliability and consistency with standard NMAP operations.

Configuration with Claude Desktop

To use this server with Claude Desktop on Windows, you'll need to configure it in the Claude configuration file located at: C:\Users\YOUR_USERNAME\AppData\Roaming\Claude\config.json

Add the NMAP server to your configuration by adding it to the mcpServers section. Here's a complete example of a Claude Desktop configuration file:

{
    "mcpServers": {
        "nmap": {
            "command": "node",
            "args": [
                "C:\\Users\\YOUR_USERNAME\\Downloads\\mcp-nmap-server\\dist\\index.js"
            ]
        }
    },
    "globalShortcut": "Ctrl+Q"
}

Replace YOUR_USERNAME with your Windows username and adjust the path to where you've installed the NMAP server.

Usage with AI

Once configured, AI assistants like Claude can use the server through the run_nmap_scan function. The function accepts the following parameters:

{
    target: string;            // Host or network to scan
    ports?: string;           // Optional port specification (e.g., "80,443" or "1-1000")
    scanType?: 'quick' | 'full' | 'version';  // Scan type (default: 'quick')
    timing?: number;          // NMAP timing template 0-5 (default: 3)
    additionalFlags?: string; // Optional additional NMAP flags
}

Example conversation with Claude:

Human: Can you scan localhost for open ports?

Claude: I'll help you scan localhost using NMAP.

<runs nmap scan with parameters>
target: "localhost"
scanType: "quick"
timing: 3
