Before you kill your PythonAnyWhere app, try to pass your redirect app url to the "health_check" tool and see what happens.

Start with black-box testing:

1. Use MCP Inspector to examine the health_check tool

2. Try to identify and exploit vulnerabilities without seeing the code

3. Document what inputs trigger unexpected behavior

If you can't find the vulnerability through black-box testing:

4. Switch to white-box analysis by reviewing tools_and_resources/health_check.py

5. Identify the security flaw in the source code

6. Craft an exploit based on your code review

Finally, share your findings and exploitation technique in the Q&A section.
