Connects Claude directly to Mobbin's design reference library so you can search and pull UI patterns from real mobile apps, web apps, and websites during conversations. You'd reach for this when designing interfaces and need to reference how other products handle specific patterns like onboarding flows, navigation menus, or form layouts. Instead of context switching to browse Mobbin separately, you can query their database inline and get concrete examples to inform your design decisions. The streamable HTTP transport means it runs remotely through their API, so no local setup beyond adding the endpoint.
