MCP-TS SDK

What it does

MCP-TS is a TypeScript client library that makes it easy to add MCP connectivity to your own web applications. It handles session management, storage backends, and agent framework integration so you can focus on building — not plumbing. It also supports the MCP Apps extension for rendering interactive tool UIs inside AI clients.

Key features

• React & Vue hooks — useMcp hook/composable for wiring MCP connections into your frontend
• Pluggable storage — choose Redis (production), SQLite (fast local), File, or In-Memory backends
• Agent adapters — drop-in support for Vercel AI SDK, LangChain, Mastra, and AG-UI
• MCP Apps extension — useMcpApps hook renders interactive tool UIs directly in AI clients
• Serverless-ready — works on Vercel, AWS Lambda, and other serverless runtimes
