NmapMCP

NmapMCP is a robust integration of the Nmap scanning tool with the Model Context Protocol (MCP), enabling seamless network scanning capabilities within MCP-compatible environments. This project allows users to perform various network scans, such as top ports scanning, DNS brute force, and more, directly through MCP interfaces.

Features

• Top Ports Scanning: Quickly identify the most commonly used ports on target hosts to assess potential entry points.

• DNS Brute Force: Discover subdomains associated with a target domain, aiding in comprehensive domain mapping.

• List Scan: Obtain a list of active hosts within a specified range without port scanning, useful for network inventory.

• OS Detection: Determine the operating system of a target host by analyzing network responses, assisting in vulnerability assessment.

• Version Detection: Identify service versions running on open ports to detect outdated or vulnerable services.

• FIN Scan: Perform stealthy scans by sending FIN packets to detect open ports without establishing a full connection.

• Idle Scan: Conduct highly stealthy scans by leveraging idle hosts to probe target systems, minimizing detection risks.

• Ping Scan: Detect active hosts in a network by sending ICMP echo requests, useful for network mapping.

• SYN Scan: Perform half-open TCP scans to identify open ports without completing the TCP handshake, reducing detection likelihood.

• TCP Connect Scan: Establish full TCP connections to probe open ports, useful when SYN scans are not feasible.

• UDP Scan: Identify open UDP ports on a target host to detect services that do not use TCP.

• Port Scan Only: Focus solely on scanning ports without additional host discovery, streamlining the scanning process.

• No Port Scan: Perform host discovery without scanning ports, useful for identifying live hosts without probing services.

• ARP Discovery: Identify active devices within a local network segment using ARP requests, effective in LAN environments.

• Disable DNS Resolution: Perform scans without resolving IP addresses to hostnames, enhancing scan speed and reducing DNS query traffic.

Installation

Installing via Smithery

To install Nmap Integration for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @0xPratikPatil/nmapmcp --client claude

Manual Installation

1. Clone the Repository:

git clone https://github.com/0xPratikPatil/NmapMCP.git
    cd NmapMCP

2. **Install uv:**

curl -LsSf https://astral.sh/uv/install.sh | sh

Configuration

To configure the Nmap MCP Server, edit the claude_desktop_config.json file located in the project root. This file allows you to set default scan arguments, define MCP tool behaviors, and adjust logging settings.

**Example claude_desktop_config.json:**

{
  "mcpServers": {
    "NmapMCP": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/NmapMCP",
        "run",
        "main.py"
      ]
    }
  }
}
