HelloMCP

The `evaluateExpression` function is a placeholder that currently returns a fixed string "42" and does not actually evaluate arbitrary expressions. If it were to be implemented with actual evaluation, it would pose a severe security risk (arbitrary code execution) and require robust input sanitization. The server primarily uses `StdioTransport`, which limits direct network exposure for the MCP protocol itself, relying on stdin/stdout for communication. No hardcoded secrets or malicious patterns observed. The code responsibly checks for macOS version and model availability before attempting to use Apple Foundation Models.
