STOP UI SLOP. Free UI Slop Gate; full UIZZE adds 800K+ real screens, search, and finish gates.
io.github.uizze/uizze MCP Server
The io.github.uizze/uizze server provides a “UI Slop Gate” and references for building distinctive user interfaces. Its description claims access to 800K+ real web and iOS screens, along with search and “finish gates.” It is positioned for use with AI coding agents and UI design workflow.
🛠️ Key Features
“Free UI Slop Gate” for stopping “UI slop”
“Full UIZZE” access to 800K+ real screens (web and iOS)
Live reference search
Product-specific design contracts
Validation, audits, and a hard “finish gate”
🚀 Use Cases
Building distinctive UI using real screen references
Supporting agent workflows that need UI reference lookup
Performing UI validation and audits before finishing
⚡ Developer Benefits
Aligns AI-driven UI work with product-specific design contracts
Enables live UI reference search for agents (e.g., Codex, Claude Code, Cursor, Copilot)
Provides validation and audit checkpoints plus a finish gate
⚠️ Limitations
Described capabilities focus on UI reference and gating; specific MCP tool names and interfaces are not provided in the source data.
Free deterministic anti-slop check for rendered HTML and CSS. Returns a score, concrete evidence, blocking issues, and fixes without calling a model or storing the submitted artifacts.

UIZZE gives Codex, Claude Code, Cursor, Copilot, and other coding agents live reference search, product-specific design contracts, validation, audits, and a hard finish gate.
The free skill works on its own. Connect the hosted UIZZE MCP when you want live search, reference packs, audits, and screenshot critique inside the agent. The repository also includes the focused uizze-ui-research and ui-slop-review skills.
Browse a public catalog of real web and iOS product UI references.
Search screens, flows, and UI elements for visual context before building.
Give supported coding agents a hosted MCP workflow with UI design contracts, implementation validation, audits, and critiques.
Try the MCP server free
Not connecting an agent yet? Score one finished screen free: upload one web or iOS screenshot for a blunt UI-slop risk score, visible evidence, and concrete fixes—no signup.
Connect https://uizze.com/mcp/preview without an account or token. The free server gives your agent one focused tool: check_ui_slop. It checks rendered HTML and CSS for generic structure, fake content, inert controls, missing states, default agent palettes, weak product specificity, and other visible UI slop—then returns concrete fixes.
Full UIZZE connects the agent to 800,000+ real web and iOS screens, live reference search, reference packs, a visual reference gallery in MCP Apps-capable clients, product-specific design contracts, implementation validation, deterministic audits, and visual critique. Get an agent token from uizze.com, then add it to the full MCP endpoint:
This repository is also a valid Codex plugin package. Its manifest lives at .codex-plugin/plugin.json and combines the public UIZZE MCP preview with the focused uizze-ui-research and ui-slop-review skills.
What the server provides
The free UIZZE MCP server returns a deterministic slop audit with evidence and fixes. Full UIZZE adds structured UI references, image URLs, OCR excerpts, ontology context, design contracts, implementation manifests, critique gates, and suggested follow-up calls.
With full UIZZE, start UI work by creating a design contract, inspect the relevant references, adapt the observed patterns to the existing design system, then validate and critique the implementation before calling it done. Do not clone brands, logos, proprietary copy, assets, or exact layouts.
