@modelcontextprotocol/client

The MCP (Model Context Protocol) TypeScript client SDK. Build MCP clients that connect to MCP servers.

[!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/client@alpha
