# `@modelcontextprotocol/server`
|
|
|
|
The MCP (Model Context Protocol) TypeScript server SDK. Build MCP servers that expose tools, resources, and prompts.
|
|
|
|
> **This is v2 of the MCP TypeScript SDK, the stable release line**, implementing the [2026-07-28 MCP spec](https://modelcontextprotocol.io/specification/2026-07-28). It replaces the single `@modelcontextprotocol/sdk` package from v1. Start with the [documentation](https://ts.sdk.modelcontextprotocol.io/v2/); coming from v1, see the [migration guide](https://ts.sdk.modelcontextprotocol.io/v2/migration/upgrade-to-v2).

## Install
|
|
|
|
```bash
|
|
npm install @modelcontextprotocol/server
|
|
```
|
|
|
|
TypeScript ≥6.0 no longer auto-includes `@types/*` — add `"types": ["node"]` to your `tsconfig.json` `compilerOptions` (the published `.d.mts` references `Buffer`).
