Subnet Calculator MCP Server

MCPOpen Source23.3

by melihteke • Automation & Orchestration

An MCP server that computes subnet details from a CIDR and exposes results via FastMCP using Server-Sent Events for easy integration into MCP-capable clients.

Example Use Cases

1
Compute subnet details (network, broadcast, netmask, wildcard mask, usable host range, and usable host count) from a CIDR input.
2
Integrate subnet calculation into chat clients or automation workflows via MCP/SSE (examples: Goose Client, Claude Desktop, n8n).
3
Validate IP ranges or generate usable host ranges when provisioning, documenting, or troubleshooting networks.

Description

This project provides a lightweight MCP tool implemented in Python that calculates subnet information (network address, broadcast, netmask, wildcard mask, usable host range, and number of usable hosts) from a given CIDR. It runs as an MCP server using FastMCP with SSE transport, making it easy to attach to clients like Goose, Claude Desktop, or automation platforms such as n8n. Installation is simple (pip install fastmcp mcp[cli]) and the README includes examples for adding the server to multiple MCP clients.
