@modelcontextprotocol/server

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

Warning

v2 is the stable release line, implementing the 2026-07-28 MCP spec. Migrating from v1? Start with the migration guide.

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

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, @modelcontextprotocol/fastify, @modelcontextprotocol/hono, @modelcontextprotocol/node.
