Questions
What exactly is a Design Contract?
An installable pack — DESIGN.md grammar, agent skills, references and config — that pins a site's design system so AI agents keep new UI on-system over time. Scans produce one automatically; Pro lets you author your own in the Studio.
What does the MCP server add?
It exposes designcontracts.sh as tools inside Claude, Cursor and any MCP client: fetch a site's tokens mid-build, profile its layout, trigger scans and compose packs without leaving your editor. Read tools are free; scanning, research and pack composition need a Pro key.
Do I need Pro to use scanned contracts?
No. Every public scan's dossier, DESIGN.md and pack download stay free. Pro is for creating your own contracts, private storage, and the full MCP toolset.
Can I cancel anytime?
Yes — cancel whenever you like and keep Pro until the end of the billing period. Paid plans come with a 14-day money-back guarantee.
