## What it is
xmcp is a TypeScript framework for building and deploying MCP (Model Context Protocol) servers, with file-system-based auto-discovery of tools, prompts, and resources. It supports HTTP and STDIO transports, integrates with Next.js, Express, Fastify, and NestJS, and includes middleware, auth, and monetization integrations.

## Use cases
- build an MCP server in TypeScript
- expose tools to Claude Desktop or Cursor
- deploy a remote MCP server over HTTP
- add MCP tools to an existing Next.js or Express app
- scaffold an MCP project with a CLI
- add authentication to MCP tool endpoints

## When to choose
- you want a batteries-included, Next.js-like DX for MCP servers
- you need both HTTP and STDIO transports
- you want automatic registration of tools, prompts, and resources
- you're deploying MCP servers to cloud or serverless environments

## When to avoid
- you need a Python MCP server
- you want stateful HTTP sessions
- you prefer manual, low-level control over the MCP protocol
- you need a language other than TypeScript
