"""
FleetMind MCP Server with Authentication Proxy
Launches both the FastMCP server and the authentication proxy.

This script:
1. Starts FastMCP server on port 7861 (internal)
2. Starts authentication proxy on port 7860 (public)
3. Handles graceful shutdown of both processes

Usage:
    python start_with_proxy.py
