//! Example demonstrating onetool integration with MCP (Model Context Protocol).
//!
//! This example creates an MCP server that exposes a Lua REPL tool.
//! MCP clients (like Claude Desktop, Cline, etc.) can connect to this server
//! and use the lua_repl tool to execute sandboxed Lua code.
//!
//! Run with: cargo run --features mcp --example mcp-basic
//!
//! # Usage with Claude Desktop
//!
//! Add this to your Claude Desktop configuration:
//!
//! ```json
//! {
//!   "mcpServers": {
//!     "onetool": {
//!       "command": "cargo",
//!       "args": ["run", "--features", "mcp", "--example", "mcp-basic"]
//!     }
//!   }
//! }
//! ```
