//! # Model Context Protocol (MCP) for Rust
//!
//! This crate provides a Rust implementation of Anthropic's Model Context Protocol (MCP),
//! an open standard for connecting AI assistants to data sources and tools.
//!
//! The implementation includes:
//! - Schema definitions for MCP messages
//! - Transport layer for communication
//! - CLI tools for generating server and client stubs
//! - Generator for creating MCP server and client stubs
