What MCP TypeScript SDK does

The TypeScript SDK implementation of the Model Context Protocol. Provides libraries for building MCP servers and clients.

Why teams reach for it: The official TypeScript implementation of the MCP specification, shipping first-party server and client libraries plus runtime and framework middleware, so a Node.js, Bun or Deno application does not hand-roll the protocol.

03 · NEW TO MCP?
What will you use to implement the protocol?

A framework or SDK gives developers pre-built code for creating an MCP server or client, so they don't have to implement the protocol from scratch.
