README.md

@modelcontextprotocol/server

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

Warning

This is an alpha release. Expect breaking changes until v2 stabilizes. We're publishing early to gather feedback — please try it and open issues — but we can't guarantee API stability yet. We'll aim to minimize disruption between alphas.

Note

This is v2 of the MCP TypeScript SDK. It replaces the monolithic @modelcontextprotocol/sdk package from v1. See the migration guide if you're coming from v1.

Install

npm install @modelcontextprotocol/server@alpha

Optional framework adapters: @modelcontextprotocol/express, @modelcontextprotocol/hono, @modelcontextprotocol/node.
