Overview
What is Subnet Calculator MCP Server?
Subnet Calculator MCP Server is a simple MCP (Model Context Protocol) server that calculates subnet details for a given CIDR (Classless Inter-Domain Routing) notation. It uses the FastMCP library and exposes subnet calculation as a tool via SSE (Server-Sent Events) transport. It is intended for network engineers, developers, or anyone who needs quick subnet calculations within an AI assistant.
How to use Subnet Calculator MCP Server?
Clone the repository or copy the script, then install dependencies: pip install fastmcp mcp[cli]. Run the server with python main.py. To add it to an MCP client, use the SSE endpoint https://mcp-subnet-calculator.mteke.com/sse — configuration steps are provided for Goose MCP Client and Claude Desktop MCP Client.
Key features of Subnet Calculator MCP Server
- Accepts a CIDR notation and returns subnet details.
- Outputs: network address, broadcast address, netmask.
- Also outputs wildcard mask and usable host range.
- Reports the number of usable hosts.
- Runs as an MCP server with SSE transport.
Use cases of Subnet Calculator MCP Server
- Quickly obtain subnet details while chatting with an AI assistant.
- Automate network design tasks within an MCP-enabled workflow.
- Validate or explore CIDR ranges without leaving the chat interface.
- Integrate subnet calculations into custom MCP clients like Goose or Claude Desktop.
Frequently asked questions
What are the installation requirements?
Python 3.7+ and the `fastmcp` library (install via `pip install fastmcp mcp[cli]`).
How do I run the server?
After installing dependencies, run `python main.py` in the project directory. The server uses SSE transport and listens for connections.
Which MCP clients are supported?
The README includes setup instructions for Goose MCP Client (via advanced settings) and Claude Desktop MCP Client (via editing the `claude_desktop_config.json` file to point to the SSE endpoint).
Is there any authentication or data persistence?
The README does not mention authentication or data storage; the server appears to perform calculations in memory and does not persist user input.
