## README

# `@modelcontextprotocol/server`

The MCP (Model Context Protocol) TypeScript server SDK. Build MCP servers that expose tools, resources, and prompts.

<!-- prettier-ignore -->
> [!WARNING]
> **v2 is the stable release line**, implementing the [2026-07-28 MCP spec](https://modelcontextprotocol.io/specification/2026-07-28). Migrating from v1? Start with the [migration guide](https://ts.sdk.modelcontextprotocol.io/v2/migration/).

<!-- prettier-ignore -->
> [!NOTE]
> This is **v2** of the MCP TypeScript SDK. It replaces the monolithic `@modelcontextprotocol/sdk` package from v1. See the **[migration guide](https://github.com/modelcontextprotocol/typescript-sdk/blob/main/docs/migration/upgrade-to-v2.md)** if you're coming from v1.

## 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`).

Optional framework adapters: [`@modelcontextprotocol/express`](https://www.npmjs.com/package/@modelcontextprotocol/express), [`@modelcontextprotocol/fastify`](https://www.npmjs.com/package/@modelcontextprotocol/fastify), [`@modelcontextprotocol/hono`](https://www.npmjs.com/package/@modelcontextprotocol/hono),
[`@modelcontextprotocol/node`](https://www.npmjs.com/package/@modelcontextprotocol/node).
