Validate Design Artifacts using MCP Server

The `validate_uiux_excellence` tool forces interfaces to adhere to strict standards, capturing details like semantic elevation (Level 0-5) and modular typographic scales. Before you index a component's usage, run it through this MCP Server. This ensures that the knowledge base populated by LlamaIndex contains only structurally sound data. If an old design was flagged for 'Rhythm Collapsed' spacing issues, your RAG application won't confuse good and bad patterns.

Grounding Design Knowledge

You can use this MCP Server output to populate a knowledge index about what constitutes 'good design.' The tool generates specific flags for failures like insufficient contrast (below 4.5:1) or failure to implement `alt` text on images. When querying past configurations, LlamaIndex retrieves answers grounded in these validated UI/UX best practices, stopping hallucinations cold.

Verify Interactivity for Indexing

Before indexing a workflow or data flow, use `validate_uiux_excellence` to confirm that all interactive elements have proper focus rings and full accessibility compliance. This includes checking the mandatory 8 states per button. This prevents your knowledge base from containing references to broken or unusable components, making your index reliable for future development.

Setup guide

Set up UI/UX Excellence Prover MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all UI/UX Excellence Prover MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to UI/UX Excellence Prover tools.",
)
response = await agent.run("List recent UI/UX Excellence Prover data")

Common questions about UI/UX Excellence Prover MCP in LlamaIndex

It validates the data structure of design artifacts before they get indexed. By confirming standards like 8-state interactions and WCAG AAA compliance, it makes your knowledge base reliable.

Yes. The tool is architecture-agnostic; it focuses purely on the underlying structural rules of design. It's perfect for standardizing inputs across any workflow.

Yes. Documentation just says 'use proper spacing.' This MCP Server proves it by checking if the whitespace adheres to a modular scale (24-48px macro vs 4-8px micro), providing measurable data.

This server touches UI/UX design structure and metadata. It only analyzes the rules governing the visual layout, never touching user credentials or sensitive operational data.

It validates that interaction components are fully specified, checking for everything from minimum 44x44px touch targets to the use of `focus-visible:ring` on all elements.
