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.

Argument	Type	Description
size	integer	Width of the code in pixels (128-1024); frames add to it
style	object	How the code looks. Leave options out for defaults (or the preset's or community item's): eyes and eye centers follow the dot color, square shapes, margin 4, level Q, no frame.
preset	string	Start from a built-in QRdx theme by id (list_options lists them); style options you set win over it
content*	object	What the code opens: a type and its fields (list_options lists the fields of every type)
include_svg	boolean	Return the SVG markup (often 50-150 KB)
logo_file_id	string	Your own logo: an image you uploaded to QRdx (PNG or JPEG, up to 1 MB), by file id. Needs the workspace's API key on this connection (Authorization: Bearer qrdx_…).
community_item	string	Start from a community theme or frame by id, such as frame:wifi-card (search_community finds them); style options you set win over it

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.

Argument	Type	Description
code	string	The id of one of the workspace's dynamic codes: the art encodes its short link, so its destination stays editable and scans are counted. Send this or text, not both.
mode	string	How the code sits in the art: "code" (default; the art painted into the code's modules), "scene" (a picture is painted from the description first, then the code is painted into its middle, so the picture runs through the code; about 40-55 seconds) or "photo" (the same with your photo as the picture; needs photo; about 25-45 seconds).
seed	integer	A seed, to make a similar image again
text	string	What the code encodes: a link or text, up to 300 characters. Send this or code, not both.

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.

read-only

Argument	Type	Description
bg	string	Background color (default ffffff) as hex, such as 000000 (in URLs leave out the # or encode it as %23)
fg	string	Bar and text color (default 000000) as hex, such as 000000 (in URLs leave out the # or encode it as %23)
data*	string	The number or text to encode. Retail numbers (EAN, UPC, ITF-14, GS1 GTINs and SSCCs) can leave the check digit off and it's added; a wrong one is an error.
text	boolean	Print the digits or text under linear barcodes (default true)
scale	integer	Pixels per module in raster images (1-10, default 4)
format*	string	The symbology: ean13, ean8, upca, upce, code128, code39, itf14, gs1-128, datamatrix, pdf417, aztec (EAN-13 and UPC-A for retail products, ITF-14 for cartons, GS1-128 for logistics labels, Code 128 for your own labels, Data Matrix, PDF417 and Aztec for 2D)

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. No scan check: use design_qr for that.

read-only

Argument	Type	Description

body	string	Shape of the data modules (default square)
data*	string	Text or URL to encode
item	string	A community theme or frame by id (search_community), such as frame:wifi-card; style and the flat options win over it
