MCP servers
Write your first MCP server and wire it to Claude
The Model Context Protocol (MCP) is a standard way to expose tools to any MCP-capable client — Claude Desktop, IDEs, or your own agents — so you write an integration once and reuse it everywhere. In this tutorial you build an MCP server in TypeScript that exposes a single typed tool over the stdio transport, test it with the MCP Inspector, then register it with Claude and call it from a real conversation. You will also learn the one rule that trips up everyone on stdio: never write to stdout. By the end you have a reusable server you can extend with your own tools.
