About

What is Niblet Designer UI?

Niblet Designer UI is a hosted UI-reference platform, MCP server, and design skill for AI coding agents.

Search real application screens, UI patterns, user journeys, and web design references by what they do, and use those references as design evidence.

Who it is for

Coding agents and the people who steer them — Codex, Claude Code, Cursor, GitHub Copilot, and similar MCP clients — when a UI task needs grounded evidence from real product interfaces instead of generic templates.

What you get

Hosted catalogue. Real iOS app screens, multi-screen journeys, UI elements, and documented web design packs, searchable by what a screen does.
Remote MCP server. Tools such as find_ui_references, find_ui_materials, get_design_reference, and get_ui_component at https://niblet-api.pymodel.com/mcp, with self-service account keys.
Local design skill. A free filesystem skill that keeps interface work anchored to the product brief and design system; MCP is optional, never a prerequisite.
REST catalogue API. Bearer-authenticated reads under https://niblet-api.pymodel.com/v1 for the same library the site browses.

Hosted, not self-hostable

Niblet Designer UI is a hosted service. There is nothing to deploy for the catalogue itself. Agents connect to the public MCP/API; the design skill installs locally without an account.
