MCP Server Integration Example

Shows how python-alfresco-mcp-server can integrate with the FIXED python-alfresco-api
wrapper clients instead of using low-level HTTP calls.

KEY BENEFITS:
- Automatic URL construction (no more manual URL building)
- Built-in authentication handling
- Cleaner, more maintainable code
- Future-proof against API changes
