"""FoodWise MCP Server - Minimal FastMCP Implementation.
This follows FastMCP best practices for simplicity and maintainability.
Configuration is handled via environment variables or CLI arguments.
Usage:
# Basic usage
python -m foodwise.mcp_server
# With custom log level
MCP_LOG_LEVEL=DEBUG python -m foodwise.mcp_server
# Using FastMCP CLI with different transports
fastmcp run src/foodwise/mcp_server/main.py
fastmcp run src/foodwise/mcp_server/main.py --transport http --port 8080
