LiteMCP

What is LiteMCP?

LiteMCP is a TypeScript framework for building MCP (Model Context Protocol) servers elegantly. It offers simple definitions for tools, resources, and prompts, with built-in logging, error handling, and CLI support for testing. The project is deprecated because the official TypeScript SDK now provides a similar high-level API.

How to use LiteMCP?

Install litemcp and zod via npm. Create a server instance, define tools, resources, or prompts, then call server.start(). Test your server in the terminal with npx litemcp dev server.js or npx litemcp dev server.ts.
