Tools of QRdx
	Description		Read-only	Idempotent	Open world
`design_qr`Design a QR code for any content type (link, Wi-Fi, contact, email, SMS, WhatsApp, payments, social profiles and more) with the style you choose: colors and gradients, dot, eye and eye center shapes, a built-in call-to-action frame with its text or a custom frame spec, a border, a logo icon or your own uploaded logo (logo_file_id, with an API key), margin and error correction. Can start from a built-in preset or a community item. Validates the content like the QRdx editor, checks the scan score with the editor's scan check and repairs the style until it is Great (at most 3 repairs, then a classic black-on-white code). Returns the score, what was changed and why, the style JSON (qrdxStyle, ready for save_template and generate_qr_code), a playground_url that opens the design in the QRdx editor, a PNG and the SVG. Call list_options first for the accepted values.

`generate_ai_art`Paint a QR code into AI artwork from a description: the art painted into the code's modules (mode "code"), a picture painted from the description with the code painted into its middle, so the picture runs through the code ("scene"), or the same with your own photo ("photo"). QRdx checks that the image scans to the content and strengthens the code just enough when it doesn't. Encodes text, or a dynamic code's short link by its id (code) so the destination stays editable and scans are counted. Needs a QRdx API key with full access on this MCP connection (Authorization: Bearer qrdx_…). Each call uses one image from the workspace's paid monthly AI art allowance (3 on Free, 30 on Pro, 150 on Business, shared by the team), refunded when no scannable image comes back. Code mode takes 15-45 seconds, photo mode about 25-45 and scene mode about 40-55 (it makes the picture first); a scene that runs out of time is refunded with AI_ART_TIMEOUT, so retry it or use code mode. Returns a 1024 px PNG, the seed, how the code was made to scan and the images left this month.

`generate_barcode`Draw a static barcode: EAN-13, EAN-8, UPC-A, UPC-E, ITF-14 and GS1-128 (check digits added or verified), Code 128, Code 39, or the 2D Data Matrix, PDF417 and Aztec. Checks the value against the format's rules (characters, length, check digit) and says what it added. Options: bar and background colors, bar height, quiet zone, scale, the text under the bars and rotation. Returns a PNG and public image URLs (SVG, PNG, JPG, WebP, AVIF, PDF and EPS) for embedding or printing. No account needed.

`generate_qr_code`Render a QR code with the editor's style options: colors or gradients (linear, radial), dot and eye shapes, eye and dot colors, a built-in frame with its text, a custom frame spec or a frame drawn as a template, a logo icon or your own uploaded logo (logoFileId, needs an API key), or a community item. Pass design_qr's qrdxStyle as style to render the same design again at another size. Returns a PNG image and public image URLs (SVG, PNG and lossless WebP for embedding in Markdown or HTML, plus a vector EPS for print); set include_svg to also get the SVG markup.
