/**
 * Example 6: MCP Server Integration
 *
 * Connects to an MCP (Model Context Protocol) server and uses
 * its tools through the agent. This example uses the filesystem
 * MCP server as a demonstration.
 *
 * Prerequisites:
 *   npm install -g @modelcontextprotocol/server-filesystem
 *
 * Run: cargo run --example 06_mcp_server
