Test script for the _parse_url_input function.
Created: 2025-08-05
Purpose: Validate the URL input parsing functionality for Fix 3 (Array Parameter Handling)
Context: Part of MCP Tools Testing issue resolution to support multiple URL inputs via JSON strings
This script was created to test the smart array parameter handling implementation that allows
the scrape_urls tool to accept both single URLs and arrays of URLs through MCP protocol,
which only supports string parameters.
Related outcomes: See mcp_tools_test_results.md for test results showing successful JSON array parsing
