How to Ship a Production-Ready MCP Server in 15 Minutes (Not Another Toy Example)

If you've built an MCP server before, you know the drill. You follow a tutorial, get a working "hello world," and then spend the next two weeks bolting on authentication, input validation, error handling, logging, and security hardening before it's anywhere close to deployable. This post walks through a TypeScript starter kit that handles all of that out of the box, so you can skip straight to writing your tool's actual logic. What is MCP? Model Context Protocol is an open standard that lets AI assistants (Claude, Cursor, Windsurf, etc.) call your code as tools. Think of it as a structured API layer between an LLM and your services. You define tools, the assistant discovers them, and calls them with validated inputs. Spec here. The problem with most MCP tutorials Every "Build Your First MCP Server" post gets you to a working stdio server in 10 minutes. Great. But then you need to actually ship it, and you're staring at a checklist like this: Input validation (not just "trust the LLM")
