NetworkCalc

networkcalc-mcp is an MCP Server that powers network calculation utilities. It exposes a set of network tools via API, enabling you to perform DNS lookups, WHOIS lookups, SPF lookups, certificate validation, and subnet analysis through a single, scalable backend.

How to use

You can access the server through an MCP client by connecting to its HTTP endpoint or by adding it to your MCP toolkit. The server provides multiple network tools you can invoke via its API, including DNS Lookup, WHOIS Lookup, SPF Lookup, Certificate Lookup, and Subnet Lookup. To start using it, connect your client to the MCP URL and call the endpoints corresponding to the tools you need. Each tool returns structured results that you can integrate into your own frontend or automation workflows.

How to install

Prerequisites you need before installation: Node.js should be available on your system. You may also need a package manager such as npm or npx.

npx -y @smithery/cli install @ramadasmr/networkcalc-mcp

Additional notes

To add the server to an MCP ecosystem via HTTP transport, you can reference the MCP URL provided for remote access. For convenience, you can also connect using your MCP client with the URL that points to the server’s MCP endpoint.
