Connect any React application to an MCP server in three lines of code

What this post added

This post introduces `use-mcp`, a React library that simplifies connecting React applications to remote Model Context Protocol (MCP) servers, handling transport, authentication, and session management in minimal code. It also open-sources the AI Playground, a chat interface built on Workers AI that uses `use-mcp` to interact with MCP servers, demonstrating dynamic tool discovery, connection management with retries, and OAuth 2.1 authentication flows. The post details how the AI Playground leverages `use-mcp` and Workers AI for tool invocation and provides debugging capabilities.
