Mobbin MCP brings real UX to agents

This is a practical fix for one of the weakest parts of AI app building: agents can generate UI, but they usually lack any grounding in what actually works.

• –Turns Mobbin from a manual inspiration library into a queryable design layer inside the build loop
• –The value is not just prettier screens, it is better constraints and fewer generic flows
• –Paid-plan gating keeps it aimed at serious product teams rather than casual vibe-coders
• –The real wedge is taste as tooling, which makes this feel more like infra for AI builders than a design gallery
• –If retrieval quality is strong, onboarding, paywall, and checkout work should improve first, because those patterns are already well represented in Mobbin
