@modelcontextprotocol/client

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

Warning

This is a beta release. The API surface is settling but breaking changes remain possible until v2 stabilizes. Please try it and open issues — feedback during the beta directly shapes the stable release.

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@beta

TypeScript ≥6.0 no longer auto-includes @types/* — add "types": ["node"] to your tsconfig.json compilerOptions (the published .d.mts references Buffer).
