WHY IT NEEDS A POLICY

Why generate_qr_urls_batch needs a policy

This tool creates/generates QR codes for provided URLs through batch processing, which is a reversible write operation. It has no destructive capability (codes can be regenerated), doesn't execute arbitrary code, poses no financial risk, and the blast radius of misuse is minimal—worst case an attacker could generate QR codes pointing to malicious URLs, but this is a common, low-impact abuse vector without data…

From the tool's definition Tool 'generates' QR code 'download URLs' and returns 'array of results' with downloadUrl for batch processing. It creates new digital artifacts (generated QR codes) that are stored and retrievable.
