## What it is
use-mcp is a lightweight React hook library for connecting browser-based AI applications to Model Context Protocol (MCP) servers. It handles connection management, OAuth authentication flows, and tool/resource/prompt invocation over HTTP and SSE transports.

## Use cases
- connect a react app to an mcp server
- add oauth authentication for mcp tool calling
- build a chat interface that calls mcp tools
- list and invoke tools from an mcp server in the browser
- read mcp server resources from a web app
- handle mcp reconnection and retries in a frontend

## When to choose
- you are building a React or TypeScript web app that talks to MCP servers
- you want managed OAuth popup flows and automatic reconnection for MCP
- you need typed access to MCP tools, resources, and prompts

## When to avoid
- you need a non-React framework or a plain Node.js MCP client
- you are building an MCP server rather than a client
- you need transports beyond HTTP and SSE
