Nmap Network Scanner MCP server

This MCP server provides a simple interface for communicating with NMAP, the popular network scanning tool, through the Model Context Protocol.

Installation

To set up the NMAP MCP server, follow these steps:

1. Create and activate a virtual environment:

python -m venv venv
source venv/bin/activate

2. Install the package in development mode:

pip install -e .

3. Start the server in development mode:

mcp dev src/server.py

Usage

After installation, the server will be running and ready to accept MCP requests that can interact with NMAP functionality. The server mediates communication between your application and NMAP, allowing you to perform network scans through the MCP interface.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
