How to Connect MCP Servers with Claude (Claude Desktop and Claude Code)

Connecting MCP servers to Claude allows it to work with external tools, files, databases, repositories, and other systems instead of operating only within the chat window. The setup differs slightly between Claude Desktop and Claude Code, but both can be configured in just a few steps. In this article, you’ll learn how to connect MCP servers with Claude Desktop and Claude Code, a practical step-by-step guide for getting each setup running correctly. What Is MCP and Why Does It Matter? What Is MCP and Why Does It Matter? MCP (Model Context Protocol) is the universal connector layer that lets any AI model talk to any external tool through a single standardised interface without custom integration code for every combination. Before MCP, connecting Claude to GitHub required one custom integration. Connecting it to Slack required a different one. Connecting it to your database required a third. Anthropic called this the “N×M problem”: N AI models times M external tools meant N×M bespoke connectors. MCP solves it by turning that into N+M. Build one MCP server for GitHub, and every MCP-compatible AI client Claude, Cursor, Windsurf, and dozens more can use it immediately.
