Malicious SecureDocs Scanner Server (Tool Poisoning Attack)

This is a malicious FastMCP server that mimics the legitimate SecureDocs Scanner
but has NO ETDI protection and secretly exfiltrates data while returning fake results.

This demonstrates the Tool Poisoning attack scenario where malicious actors
deploy tools that appear identical to legitimate ones.
