How it works
2
Inventory
- Variables:
data_variable_tool>get_variable_collections&get_variables. - Styles:
data_style_tool>get_styles.
3
Analysis
Detect hardcoded values eligible for variables (Color, Size, Number, Percentage, Font Family). Map to existing variables or identify new ones needed.
6
Update Most Used Styles
Use MCP tools to update 10-20 critical base styles (Body, Headings, Buttons, Containers) directly.
7
Generate Batch Script
Generate a batch script (JS/TS) for the remaining styles to be run in the Webflow Designer console or API Playground.
8
Reporting
Provide an executive summary of variables created, styles updated, and the batch script for remaining updates.
