How to Use the Design Prover MCP in Cursor

Q: How do I set up Design Prover for my project in Cursor?

Create a .cursor/mcp.json file in your project's root folder. Add the Design Prover server configuration from Vinkius. Cursor's agent will automatically find and use the tool for that project.

Q: Can my whole team use the same Design Prover setup in Cursor?

Yes. Just commit the .cursor/mcp.json file to your git repository. Anyone on your team who pulls the project and uses Cursor will have the exact same tool configuration and design guardrails.

Get frontend code that doesn't look AI-generated, injected directly into your files by Cursor's agent.

Ship UIs with a Point of View

The `prove_design` tool is a guardrail against bland, AI-generated frontends. Cursor's agent is great at writing code, but it can fall back on the same tired layouts. This tool stops that from happening. It forces the agent to validate its design choices before a single line of code is written. Does it have hierarchy? Is the layout interesting? Does the color palette say something? If not, the design is rejected, and the agent has to think harder. You get code for UIs that have actual intent behind them.

A Pre-flight Check for UI Code

Think of it as a linter for design aesthetics. Before the agent generates HTML and CSS in your editor, it first has to pass the `prove_design` check. It sends a plan outlining the focal point, layout, whitespace, typography, and color scheme. The tool runs that plan against its five core principles. It's looking for proof of intentional design—asymmetric columns, dramatic type scale, and a justified color palette. The code that Cursor injects has already been vetted for you.

From Prompt to Proven Code in Cursor

The whole process happens inside your editor without any extra steps. You prompt the agent to build a component, it silently runs its design plan by this MCP server, and then injects the approved code. You don't even see the check unless it fails. When it does fail, the agent will tell you why, letting you adjust your prompt. This workflow makes sure the code hitting your files has already passed a design quality gate. No more generating a full component just to realize it looks boring and needs a total rewrite.

Setup guide

Set up Design Prover MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Design Prover MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Design Prover transactions." If the MCP tools are loaded correctly, Cursor will call the Design Prover tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "design-prover-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }

Common questions about Design Prover MCP in Cursor

Create a `.cursor/mcp.json` file in your project's root folder. Add the Design Prover server configuration from Vinkius. Cursor's agent will automatically find and use the tool for that project.

No. It's a stateless check that takes milliseconds. The agent sends a small text plan, gets a simple pass/fail response, and moves on. It's a tiny delay that prevents you from wasting time refactoring a bad UI later.

It checks the agent's plan against five rules of good design: a clear focal point, an unpredictable layout, designed whitespace, high-contrast typography, and a meaningful color palette. It's built to kill the default 'AI aesthetic'.

Yes. Just commit the `.cursor/mcp.json` file to your git repository. Anyone on your team who pulls the project and uses Cursor will have the exact same tool configuration and design guardrails.

It only processes the agent's proposed design plan—a short text description of the UI it intends to build. It never sees your source code, filenames, or any other project data. The check runs in an ephemeral Vinkius sandbox that is destroyed after each request.
