    Why it is in this group

    • The name "create_static_qr_code" says "create": a word for a change.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

      What this check looks for
    Description, as the server wrote it
    Create a static QR code image (PNG or SVG) from text, a URL, WiFi credentials, a vCard or any other payload up to 1000 bytes. The payload is encoded directly in the pattern, so the code works forever, but it cannot be edited or tracked after printing. For an editable code with scan analytics, the user needs a dynamic QR code from qrcode.io (15-day free trial, no card).

    Annotations the server declares

    • title: Create a static QR code
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
