UIZZE MCP

STOP UI SLOP.

If your UI looks AI-generated, you've already lost the first impression.

UIZZE arms Codex, Claude Code, Cursor, and Copilot with 800,000+ real web and iOS interfaces, live reference search, product-specific design contracts, validation, audits, and a hard finish gate before generic UI reaches users.

Install the free UIZZE anti-slop skill

Give Codex, Claude Code, or Cursor a workflow grounded in 800,000+ real web and iOS screens, a design contract, and a hard finish gate:

npx skills add https://uizze.com --skill anti-ui-slop

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.

→ Read the anti-slop UI workflow

→ Run the AI UI slop preflight checklist

→ Copy an anti-slop UI research, contract, validation, and critique prompt

→ Follow the UI reference cookbook for coding agents

Use UIZZE to:

• 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

Connect https://uizze.com/mcp 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.

Codex

Unlock full UIZZE

Full UIZZE connects the agent to 800,000+ real web and iOS screens, live reference search, reference packs, product-specific design contracts, implementation validation, deterministic audits, and visual critique. Get an agent token from uizze.com, then add it to the same endpoint:

URL: https://uizze.com/mcp
Authorization: Bearer <your UIZZE agent token>

Store the token in local agent configuration or an environment variable only. Do not commit it.

Codex

export UIZZE_AGENT_TOKEN="uizze_at_your_token"
codex mcp add uizze --url https://uizze.com/mcp --bearer-token-env-var UIZZE_AGENT_TOKEN

Claude Code

claude mcp add --transport http uizze https://uizze.com/mcp --header "Authorization: Bearer uizze_at_your_token"

Cursor

      }
    }
  }

Codex plugin

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.
