Universal MCP Server for Google Stitch
Stitch MCP
Universal MCP Server for Google Stitch
Build amazing UI/UX designs instantly with AI. Works seamlessly with Cursor, Claude, Antigravity, and any MCP-compatible editor.
Created by Aakash Kargathara.
đ How It Works
⨠Why this is cool
- Zero Config: Just login once and it works everywhere.
- Universal: Works on Windows, Mac, and Linux.
- Free: Google Stitch API is free to use.
īŋŊī¸ Quick Setup (2 Minutes)
1. Prerequisite: Google Cloud
You need a Google Cloud project with the Stitch API enabled.
# Login to your Google Cloud
gcloud auth login
# Set your project (replace with your actual project ID)
gcloud config set project YOUR_PROJECT_ID
gcloud auth application-default set-quota-project YOUR_PROJECT_ID
# Enable the magic
gcloud beta services mcp enable stitch.googleapis.com
2. Install the Credentials
This gives stitch-mcp permission to talk to Google on your behalf.
gcloud auth application-default login
3. Add to Your AI Editor
Copy and paste this into your MCP config file:
For Claude Desktop:
~/Library/Application Support/Claude/claude_desktop_config.json
For Cursor: Settings > MCP > Add New Server
{
"mcpServers": {
"stitch": {
"command": "npx",
"args": ["-y", "stitch-mcp"],
"env": {
"GOOGLE_CLOUD_PROJECT": "YOUR_PROJECT_ID"
}
}
}
}

đĄ Pro Tip: The "Designer Flow"
To generate consistent UI, use this 2-step flow:
- Extract: "Get design context from the Home Screen..."
- Generate: "Using that context, generate a Chat Screen..."
This ensures your new screen matches your existing design system perfectly.
