Authorization (optional)

Optional. 'Bearer <key>' for higher limits. Works without a key.

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

barcode_generate Read-only

Code 128, EAN-13, UPC-A or EAN-8 as SVG/PNG/data URL. EAN/UPC: pass digits without check digit to have it added, or with it to verify. Static codes only: no redirects, no dynamic/editable codes, no scan analytics. EAN/UPC output is format-valid (check digit) and is NOT GS1 registration. Scannability is not guaranteed (contrast, print size, quiet zone and reader all matter).

qr_generate

Generate a static QR code as SVG (default, up to 2000 px), PNG base64 or data URL (up to 1024 px) from data or a payload object. Bulk (/v1/qr/bulk, ≤50) is SVG-only, ≤256 bytes per item. Static codes only: no redirects, no dynamic/editable codes, no scan analytics. EAN/UPC output is format-valid (check digit) and is NOT GS1 registration. Scannability is not guaranteed (contrast, print size, quiet zone and reader all matter).
