Tools: make_label, edit_label, fill_template, find_template, list_catalog, open_zpl_viewer.

How you work with a person

1. They ask for a label (brand, ingredients, look, size, a logo URL).
2. You call make_label (custom look) or fill_template (known job like soap-wrap).
3. You reply with the preview image and the editor URL. One click, no signup.
4. They say “make the title bigger” or “darker background.” You call edit_label with the spec you saved plus the change.
5. You send the new URL. Repeat. Each edit is a new link. They can also open the last link and finish in the app (text, barcode, QR, image, shape, table, print).

Canvas tools in the free label maker

These match the left rail. Put them in make_label / edit_label, or in a GET URL.

Tool	What you set
Size	w and h in inches (0.25–12). Bottle face 2.5×4. Shipping 4×6. Lid 2×2.
Background	look (premium-masculine, premium, luxury, minimal, clean, organic, vintage, bold, soft) or bg / ink / accent hex.
Text	Place with els: type text, v copy, x,y,w,h percent (0–100), s font px, f font, c color, a l/c/r, b bold. Or fill title, kicker, body, net on a look.
Image	img = https URL of a logo. Or an el type image with src. Or icon=drop.
Shape	el type shape, k = rect, round, circle, ellipse, line, vline, triangle, star, heart, drop, diamond, capsule.
Barcode	el type barcode, v payload, fmt CODE128, CODE39, EAN13, UPC, DATAMATRIX. Do not invent GS1 prefixes.
QR	el type qr, or value = URL. WiFi: ssid + pass. vCard: put a BEGIN:VCARD string in value.
Table	el type table, rows, cols, cells as a 2D array of strings.
Number	add_number, prefix (SKU-), start, pad, copies. Places {{#}} and a CODE128 barcode. Browse Label 1/N, then print.
Date	add_today and/or add_use_by. date_format (M/D/YYYY or YYYY-MM-DD). use_by_days.
Variables	Spreadsheet: rows as objects, or csv text, or sheet Google Sheets URL. Places {{column}} tokens. One label per row. Print all rows.
ZPL Viewer	Call open_zpl_viewer with zpl, or pass zpl on make_label. Preview is a picture. Print sends the pasted job.

Coordinates are percent of the label. Font size is canvas pixels (a 2.5×4 in label is about 250×400 px: title 32–42, kicker 11, body 10–12).

Example: premium masculine shampoo

User: “Use mylabelmaker. Make a label for a shampoo brand called Spot. Here are the ingredients. I want it to feel premium and masculine.”

Call make_label with look premium-masculine, w 2.5, h 4, title SPOT, kicker SHAMPOO, body the ingredients, net NET 8 FL OZ. Then send:

https://mylabelmaker.com/preview.svg?canvas=1&look=premium-masculine&w=2.5&h=4&title=SPOT&kicker=SHAMPOO&body=Water%2C%20glycerin.&net=NET%208%20FL%20OZ

https://app.mylabelmaker.com/?canvas=1&look=premium-masculine&w=2.5&h=4&title=SPOT&kicker=SHAMPOO&body=Water%2C%20glycerin.&net=NET%208%20FL%20OZ

If they then say “make the background black and add a gold line,” call edit_label with the saved spec plus bg and an add_el shape line. Send the new pair of URLs.

Spreadsheet, numbers, dates, ZPL

If they paste a table or share a Google Sheet, call make_label with rows (array of objects) or sheet (the URL). The canvas gets {{sku}}, {{name}}, and a barcode. They open the link, step through rows under the canvas, and print all. Cap is 80 rows in the URL. Bigger lists: publish the Sheet to the web and pass sheet.

make_label
  rows: [{sku:"A-1", name:"Widget"}, {sku:"A-2", name:"Bolt"}]
  barcode_column: sku
  add_number: true
  add_today: true

Serial-only (no sheet): add_number, prefix:"SKU-", start:1, copies:50, pad:3. Packed dates: add_today and add_use_by with use_by_days:14.

ZPL they already have: open_zpl_viewer with the ^XA…^XZ string. Keep it short in the URL; long jobs they paste in the viewer.

Place objects yourself

When they want a specific layout, pass els (or repeat el= on a GET URL):

el=text:SPOT;x:8;y:16;w:84;h:16;s:40;f:Oswald;c:f5f0e8;a:c;b
el=s:rect;x:0;y:0;w:100;h:3;c:b8a47a
el=i:https://example.com/logo.png;x:40;y:6;w:20;h:10

If you cannot call MCP

Build the same GET URLs yourself. Encode every value (encodeURIComponent). Same contract: /ai/canvas.txt, templates /ai/make.txt, catalog /ai/catalog.json, OpenAPI /openapi.json, facts /llms.txt.
