Capabilities

Tools 6

quality_qr_analytics

Get scan analytics for a specific QR code. Use this when the user wants to know how many times a QR code has been scanned, see daily scan trends, understand which devices are scanning, or see which countries scans come from. Returns total scans, scans by day, device breakdown (mobile/tablet/desktop), and top 5 countries.

Discovered
quality_qr_create

Create a new trackable QR code saved to your Quality QR account. Use this when the user wants to generate a QR code for a URL, WiFi network, contact card, calendar event, phone number, email, SMS, restaurant menu, app download link, or social media profile. The QR code is persisted with scan tracking and analytics. Returns an inline SVG image of the QR code.

Discovered
quality_qr_delete

Permanently delete a QR code from the user's account. Use this when the user wants to remove a QR code they no longer need. The short URL will immediately stop redirecting. This action frees up a plan quota slot and cannot be undone.

Discovered
quality_qr_get

Get full details of a specific QR code by its ID. Use this when the user wants to inspect a particular QR code's configuration, check its destination URL, view its design settings, or see its current status. Returns all metadata including content, destination, design, scan limits, and timestamps.

Discovered
quality_qr_list

List QR codes in the user's Quality QR account. Use this when the user wants to see their existing QR codes, find a specific code, or check how many codes they have. Returns ID, name, type, short URL, active status, and creation date for each code.

Discovered
quality_qr_update

Update an existing QR code's properties. Use this when the user wants to change where a QR code points to, rename it, or enable/disable it. Destination URL changes only work for dynamic URL-based types (url, pdf, menu, app-store, social). Name and active status can be changed for any QR code type.
