Marque – MCP/CLI server for persistent agent design identity

Hey HN, I'm Parth, a high school senior who built Marque after getting frustrated with the same problem on every project. Every AI coding agent starts from zero. It has no memory of your color semantics, your typographic scale, your spacing rhythm, or the visual decisions you have already made. So it defaults to the centroid of everything it has ever seen. Rounded cards. Blue buttons. Gradient blobs. The same page it builds everyone. You either paste 200 words of design context into every single prompt or you accept generic output by default. I wanted something that lived at the infrastructure level rather than the prompt level.

That is what Marque is.

npm install -g marque-cli marque stamp stripe.com marque synthesize --apply marque mcp setup

marque synthesize turns that into an actionable mark: a concept philosophy with a core metaphor, a pattern vocabulary with JSX blueprints, anti-defaults telling the agent exactly what not to build, and section guidance per page type.

marque mcp setup writes config files for Claude Code, Cursor, Copilot, Windsurf, Codex, and Antigravity simultaneously. The agent calls get_design_context_for() before it writes a single line.

Real design taste is never singular though. Kirby Ferguson's Everything is a Remix maps directly here: the best design is copy, transform, combine. marque blend lets you pass multiple references with weights, scrapes them in parallel, interpolates the typography scale numerically, resolves color dominance by weight, and synthesizes a concept philosophy describing the creative tension between the references as a named design identity. Not averaging two sites. Creating something original from the intersection of what you admire.

And once the agent starts building, marque improve keeps it honest. Agents drift. By the third component they are back to generic defaults. The improve loop screenshots your running dev server, diffs it against your mark using a vision model, writes element level violations by severity to a corrections file, and re-scores on every file change until the output actually matches.

marque improve --url localhost:3000 --target 85

The goal is simple: vibe-coded products should look as good as they build fast. Everything is free and open source.
