Ip Calc Mcp
io.github.ryudi84Published by GitHub account ryudi84v1.0.2Updated Oct 24, 2026
IP address and subnet calculator, CIDR notation
The publisher's own server: calc.engineer
Overview
A local MCP server that lets an assistant analyze IP addresses, calculate subnet details from CIDR notation, and test whether an IP falls in a range.
- What you can do
- It provides three tools: analyze_ip determines an address's class, type (private, public, loopback, multicast) and binary form; calculate_subnet derives subnet details from an IP/CIDR input such as 192.168.1.0/24; and ip_in_range checks whether an address lies inside a given CIDR range. It is a small, focused networking utility rather than a general-purpose toolset.
- When to use it
- Useful when working with network configuration, CIDR blocks, or subnet planning and you want the assistant to do the arithmetic and range checks directly in the editor instead of switching to a separate calculator. It fits developer and operations workflows that involve IP addressing.
- Requirements
- Runs locally as a stdio process, typically launched with npx ip-calc-mcp, so Node.js and npm are needed. No authentication, environment variables, or headers are declared.
Installation
In SourceWeft
- Open Ip Calc Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
