What is Subnet Calculator Mcp Server

Subnet-Calculator-MCP-Server is a simple Model Context Protocol (MCP) server designed to calculate subnet details based on CIDR (Classless Inter-Domain Routing) notation. It utilizes the FastMCP library to provide subnet calculation functionalities.

Use cases

Use cases include network configuration, troubleshooting IP address allocation, and educational demonstrations on subnetting concepts.

How to use

To use the Subnet-Calculator-MCP-Server, clone the repository, install the required dependencies using ‘pip install fastmcp mcp[cli]’, and run the server with ‘python main.py’. You can then add the server to your MCP client by following the specific client instructions provided in the README.

Key features

Key features include calculating subnet details such as network address, broadcast address, netmask, wildcard mask, usable host range, and the number of usable hosts. It operates as an MCP server with Server-Sent Events (SSE) transport.

Where to use

Subnet-Calculator-MCP-Server can be used in network management, educational environments for teaching subnetting, and by developers needing to integrate subnet calculation into their applications.

Subnet Calculator MCP Server

This project provides a simple MCP (Model Context Protocol) server for calculating subnet details based on a given CIDR (Classless Inter-Domain Routing) notation. It uses the FastMCP library to expose the subnet calculation functionality as a tool.

Features

1. Calculate subnet details for a given CIDR.
2. Provides:

• Network address
• Broadcast address
• Netmask
• Wildcard mask
• Usable host range
• Number of usable hosts

3. Runs as an MCP server with SSE (Server-Sent Events) transport.

Requirements

• Python 3.7+
• fastmcp library

Installation

• Clone the repository or copy the script.
• Install the required dependencies:

pip install fastmcp mcp[cli]

Usage

THis MCP runs with SSE transport mode.

Run the MCP server:

python main.py
