PyPI Query MCP Server - Prompt Templates Demo

This script demonstrates how to use the MCP prompt templates for PyPI package analysis,
dependency management, and migration planning.

The prompt templates provide structured guidance for common PyPI package scenarios:
- Package quality analysis
- Package comparison and selection
- Dependency conflict resolution
- Security auditing
- Migration planning
