About MCP TypeScript SDK

The Model Context Protocol (MCP) allows applications to provide context for LLMs in a standardized way, separating the concerns of providing context from the actual LLM interaction. This repository contains the TypeScript SDK implementation of the MCP specification. It runs on **Node.js**, **Bun**, and **Deno**, and ships: Tool and prompt schemas use Standard Schema — bring Zod v4, Valibot, ArkType, or any compatible library.
