MCP servers turn Claude into a reasoning engine for your data

The article explains how Model Context Protocol (MCP) servers let Claude connect directly to external data and tools.

It walks through building a simple MCP calculator server in TypeScript, using the Anthropic SDK, Zod validation, and StdioServerTransport.

The setup shows how Claude Desktop can communicate with the server and call its tools without manual copy-paste workflows.

The broader point is that MCP makes it easier for companies to expose data and functionality to AI assistants for more relevant reasoning.
