## Prerequisites (Install These First)

### 1. Install Node.js (v18 or higher)

#### Windows
```powershell
# Using winget (Windows 10/11)
winget install OpenJS.NodeJS.LTS

# Or download installer from: https://nodejs.org/
```

#### macOS
```bash
# Using Homebrew
brew install node@22

# Or download installer from: https://nodejs.org/
```

#### Linux / WSL
```bash
# Using nvm (recommended)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
source ~/.bashrc
nvm install 22
nvm use 22

# Or using apt (Ubuntu/Debian)
curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
sudo apt-get install -y nodejs
```

**Verify Node.js installation:**
```bash
node --version   # Should show v18.x.x or higher
npm --version    # Should show 9.x.x or higher
```

---

### 2. Install Google Cloud CLI (gcloud)

#### Windows

**Option A: Installer (Recommended)**
1. Download from [Google Cloud SDK](https://cloud.google.com/sdk/docs/install)
2. Run the installer (check "Run gcloud init" option)
3. Restart your terminal

**Option B: PowerShell**
```powershell
(New-Object Net.WebClient).DownloadFile("https://dl.google.com/dl/cloudsdk/channels/rapid/GoogleCloudSDKInstaller.exe", "$env:TEMP\gcloud.exe")
Start-Process "$env:TEMP\gcloud.exe" -Wait
# Restart terminal after installation
```

#### macOS
```bash
# Using Homebrew (Recommended)
brew install --cask google-cloud-sdk

# Or direct install
curl https://sdk.cloud.google.com | bash
exec -l $SHELL
```

#### Linux / WSL
```bash
# Download and install
curl -sSL https://sdk.cloud.google.com | bash -s -- --disable-prompts --install-dir=$HOME

# Add to PATH
echo 'export PATH="$HOME/google-cloud-sdk/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
```

**Verify gcloud installation:**
```bash
gcloud --version
# Should show: Google Cloud SDK xxx.x.x
```

---

## Quick Start

After installing Node.js and gcloud CLI:

```bash
npx stitch-mcp-auto-setup
```

The setup wizard will:
1. Open a web-based setup page at `http://localhost:51121`
2. Guide you through Google login
3. Help you select or create a project
4. Enable the Stitch API
5. Save your configuration

> **Note:** When starting the MCP server directly (`npx stitch-mcp-auto` or via your editor), the setup wizard runs on `http://localhost:8086`.

> **🤖 AI Agent Note (WSL Environment):**
> If running in WSL, the browser cannot open automatically. Open the URL shown in the terminal (usually `http://localhost:51121` for `setup.js`, or `http://localhost:8086` when the MCP server starts) in your Windows browser:
> ```powershell
> # Run this in PowerShell (not WSL terminal)
> Start-Process "http://localhost:51121"
> # If you see 8086 instead:
> Start-Process "http://localhost:8086"
> ```
> Or instruct the user to manually open the shown URL in their Windows browser.

---

## AI Agent Quick Start (Semi-Automated)

This repo supports **semi-automated setup** with a few unavoidable manual steps (OAuth login).

**Checklist (agent-friendly):**
1. Run setup: `npm run setup` (or `npx -p stitch-mcp-auto stitch-mcp-auto-setup`)
2. Open the URL shown in terminal (usually `http://localhost:51121`)
3. Complete Google login in the browser (gcloud + Stitch API enable)
4. **⚠️ CRITICAL: Verify MCP registration** (see below)
5. Start server: `npm start` or let the editor launch it

**Manual-only steps:**
- Browser OAuth consent (Google login)
- WSL browser opening (must open URL manually)

**Environment-specific commands:**
- **Windows (PowerShell):**
  - Open setup URL: `Start-Process "http://localhost:51121"` (or `http://localhost:8086`)
- **macOS:**
  - Open setup URL: `open "http://localhost:51121"` (or `http://localhost:8086`)
- **Linux:**
  - Open setup URL: `xdg-open "http://localhost:51121"` (or `http://localhost:8086`)
- **WSL (Windows host):**
  - Run in Windows PowerShell: `Start-Process "http://localhost:51121"`

### ⚠️ Post-Installation MCP Verification (REQUIRED)

After setup completes, **always verify** that the MCP server is registered:

```bash
# Claude Code
claude mcp list | grep stitch

# Gemini CLI
gemini mcp list | grep stitch

# Codex CLI
codex mcp list | grep stitch
```

**If `stitch` is NOT listed**, manually register:

| CLI | Manual Registration Command |
|-----|----------------------------|
| Claude Code | `claude mcp add -e GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID -s user stitch -- npx -y stitch-mcp-auto` |
| Gemini CLI | `gemini mcp add stitch -- npx -y stitch-mcp-auto --env GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID` |
| Codex CLI | `codex mcp add stitch -- npx -y stitch-mcp-auto --env GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID` |

> **Why verification is needed:** The setup wizard writes directly to config files (`~/.claude.json`, `~/.gemini/settings.json`, `~/.codex/config.toml`), but verification ensures the configuration is correct. Always verify to avoid "MCP server not found" errors.

**Other Verification (optional):**
- `node auth.js --status` (shows token + project status)
- `npm start` (server boots and prints "Ready")

---

## Manual Installation (Alternative)

### Step 1: Run Auto Setup

```bash
npx -p stitch-mcp-auto stitch-mcp-auto-setup
```

Or if you cloned the repository:
```bash
node setup.js
```

#### Setup Process

1. **Welcome Page** - Click "Login with Google" button
2. **Google Login** - A new browser window opens for authentication
   - After login, you may see "Connection refused" page - **just close it**
   - The setup page will automatically detect your login
3. **Project Selection** - Choose an existing project or create a new one
4. **API Activation** - Click the button to enable Stitch API
   - Wait for activation (may take a few seconds)
5. **Complete** - Copy the MCP configuration to your editor

> **⚠️ WSL Users - IMPORTANT:**
> WSL cannot open browsers directly. When the setup wizard starts:
> 1. Copy the URL `http://localhost:51121`
> 2. Open it manually in your **Windows browser** (Chrome, Edge, etc.)
> 3. Or run in PowerShell: `Start-Process "http://localhost:51121"`
>
> The authentication will work because WSL shares localhost with Windows.

---

### Step 3: Configure MCP Client

After setup completes, add the configuration to your MCP client.

#### Claude Desktop

**macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows:** `%APPDATA%\Claude\claude_desktop_config.json`

```json
{
  "mcpServers": {
    "stitch": {
      "command": "npx",
      "args": ["-y", "stitch-mcp-auto"],
      "env": {
        "GOOGLE_CLOUD_PROJECT": "YOUR_PROJECT_ID"
      }
    }
  }
}
```

#### Claude Code

**🌐 Method 1: CLI Command (Recommended)**

The setup wizard automatically writes to `~/.claude.json`.
To add manually via CLI:

```bash
claude mcp add -e GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID -s user stitch -- npx -y stitch-mcp-auto
```

Or edit `~/.claude.json` directly:

```json
{
  "mcpServers": {
    "stitch": {
      "command": "npx",
      "args": ["-y", "stitch-mcp-auto"],
      "env": {
        "GOOGLE_CLOUD_PROJECT": "YOUR_PROJECT_ID"
      }
    }
  }
}
```

**📁 Method 2: Per-project Settings**

Create `.mcp.json` in your project root:

```json
{
  "mcpServers": {
    "stitch": {
      "command": "npx",
      "args": ["-y", "stitch-mcp-auto"],
      "env": {
        "GOOGLE_CLOUD_PROJECT": "YOUR_PROJECT_ID"
      }
    }
  }
}
```

#### Gemini CLI

**🌐 Method 1: CLI Command (Recommended)**

```bash
gemini mcp add stitch -- npx -y stitch-mcp-auto --env GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID
```

Or edit `~/.gemini/settings.json` directly:

```json
{
  "mcpServers": {
    "stitch": {
      "command": "npx",
      "args": ["-y", "stitch-mcp-auto"],
      "env": {
        "GOOGLE_CLOUD_PROJECT": "YOUR_PROJECT_ID"
      }
    }
  }
}
```

#### Codex CLI

**🌐 Method 1: CLI Command (Recommended)**

```bash
codex mcp add stitch -- npx -y stitch-mcp-auto --env GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID
```

Or edit `~/.codex/config.toml` directly:

```toml
[mcp_servers.stitch]
command = "npx"
args = ["-y", "stitch-mcp-auto"]

[mcp_servers.stitch.env]
GOOGLE_CLOUD_PROJECT = "YOUR_PROJECT_ID"
```

#### Cursor

Go to **Settings > MCP > Add New Server** and add:
- Command: `npx`
- Args: `-y stitch-mcp-auto`
- Environment: `GOOGLE_CLOUD_PROJECT=YOUR_PROJECT_ID`

**Optional:** `GOOGLE_CLOUD_PROJECT` is only used for Stitch image fallback and `auth.js --status`. The setup wizard stores the active project in `~/.stitch-mcp-auto/config.json`, and workspace tools save `.stitch-project.json` in your current folder.

---

## Available Tools

### 🔄 Automatic Project Management (NEW)

**No more manual projectId passing!** The server automatically manages project context:

1. **Auto-detection**: When you call tools like `generate_screen_from_text` without `projectId`, it automatically uses the workspace project
2. **Auto-save**: When you `create_project`, it's automatically saved to `.stitch-project.json` in your current folder
3. **Session continuity**: Return to the same folder later, and your project is automatically loaded

**How it works:**
```
┌─────────────────────────────────────────────────────────────┐
│  Tool called without projectId                              │
│                      ↓                                      │
│  1. Check active session project                            │
│  2. If none → Load from .stitch-project.json                │
│  3. If none → Return "PROJECT_REQUIRED" with options        │
│                      ↓                                      │
│  User creates/selects project → Auto-saved to workspace     │
└─────────────────────────────────────────────────────────────┘
```

| `extract_components` | Extracts reusable UI component patterns (buttons, cards, forms) with their styles. |

#### Design Enhancement Tools

| Tool | Description |
|------|-------------|
| `suggest_trending_design` | Applies 2024-2025 UI trends (glassmorphism, bento-grid, gradient-mesh, etc.) to screen generation. |
| `generate_style_guide` | Generates a comprehensive style guide/design documentation from an existing design. |
| `export_design_system` | Exports a complete design system package (tokens, components, docs) for developer handoff. |

### 🎨 AI Image Generation Tools (v1.1.0)

These tools have different authentication requirements:

| Tool | Auth Required | Description |
|------|---------------|-------------|
| `generate_design_asset` | **Antigravity** | Generate design assets (logo, icon, illustration, hero, wireframe, background, pattern) using Gemini models. **Requires Antigravity authentication.** Supports model selection (gemini-3-pro, gemini-2.5-pro) and forced auth. |
| `orchestrate_design` | Stitch + Antigravity | Full orchestration: auto-generates assets (logo, icons, hero) then creates complete UI. Stitch-only users can generate UI pages without custom assets. |
| `check_antigravity_auth` | None | Check Antigravity OAuth authentication status for image generation features. |

#### Supported Models for Image Generation

| Model | Status | Image Generation | Description |
|-------|--------|------------------|-------------|
| `gemini-3-pro` | ✅ Available | ✅ Supported | **Default.** Latest Gemini 3 Pro model with image generation |
| `gemini-2.5-pro` | ✅ Available | ✅ Supported | Gemini 2.5 Pro model with image generation |

> **See also:** `ANTIGRAVITY-MODELS.md` (EN) / `ANTIGRAVITY-MODELS.ko.md` (KO) for the full model list, thinking variants, and endpoint details.

> **💡 Model Selection:**
> You can specify a model when calling `generate_design_asset`:
> ```json
> {
>   "assetType": "logo",
>   "prompt": "Modern tech company logo",
>   "model": "gemini-3-pro"
> }
> ```

**Key parameters (`generate_design_asset`):**
- `assetType`: logo, icon, illustration, hero, wireframe, background, pattern
- `aspectRatio`: 1:1, 16:9, 9:16, 4:3, 3:4
- `saveToFile`: `true` by default (saves to current directory)
- `forceAntigravityAuth`: `true` to trigger browser login

> **📋 Role Separation:**
> - **Stitch API (gcloud auth):** UI page/screen generation - available to all users
> - **Antigravity OAuth:** Image asset generation (logo, icon, hero) - requires separate authentication
>
> Stitch-only users can still create complete UI pages using `generate_screen_from_text`. Antigravity extends this with custom AI-generated assets.

#### 🔲 Background Removal (NEW)

`generate_design_asset` supports automatic background removal for transparent assets:

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `removeBackground` | boolean | `false` | Enable automatic background removal |
| `backgroundRemovalMode` | `"white"` \| `"auto"` | `"white"` | `white`: Remove white backgrounds. `auto`: Auto-detect solid colors. |
| `backgroundThreshold` | number | `240` | Threshold for detection (0-255). Higher = more aggressive. |

**Example:**
```json
{
  "assetType": "logo",
  "prompt": "Modern tech company logo with abstract shapes",
  "removeBackground": true,
  "backgroundRemovalMode": "white",
  "backgroundThreshold": 240
}
```

This produces a transparent PNG, ideal for:
- **Logos** - No white border when placed on colored backgrounds
- **Icons** - Clean integration into UI designs
- **Illustrations** - Seamless overlay on any background

---

```

```
Create a Tailwind config based on the home screen
```

### Trending Design Generation

Apply modern UI/UX trends automatically:

```
Create a pricing page with glassmorphism and gradient-mesh effects
```

```
Design a dashboard using bento-grid layout and dark mode
```

### Batch Screen Generation

Create multiple screens at once with consistent styling:

```
Generate a complete onboarding flow: welcome, features, signup, and confirmation screens
```

### Accessibility Check

Ensure your designs are accessible:

```
Check the login page for WCAG AA compliance
```

### Design System Export

Export for developer handoff:

```
Export the complete design system from this project including tokens and components
```

### AI Image Generation (NEW in v1.1.0)

Generate design assets with AI:

```
/generate-asset logo "Eco-friendly organic food delivery service called GreenBite"
```

```
/generate-asset hero "Modern fintech app showing financial growth" --style gradient --ratio 16:9
```

```
/generate-asset icon "Shopping cart with checkmark" --style flat --colors "#4CAF50"
```

### Full Design Orchestration (NEW in v1.1.0)

One prompt to complete design - automatically generates assets and creates UI:

```
/design-full "친환경 유기농 식품 쇼핑몰 메인 페이지. 녹색 테마, 신선한 느낌, 모던한 디자인"
```

```
/design-full "AI-powered project management tool landing page. Professional, blue gradient theme, with pricing section"
```

> **Note:** The orchestration mode automatically:
> 1. Analyzes required assets (logo, hero, icons)
> 2. Generates each asset using Gemini 3 Pro (requires Antigravity auth)
> 3. Creates complete UI screen with Stitch API
> 4. Returns all assets + final UI in one response
>
> **Without Antigravity auth:** UI screen is still generated, but without custom image assets.

## Troubleshooting

### "gcloud: command not found"

**Linux/macOS/WSL:**
```bash
export PATH="$HOME/google-cloud-sdk/bin:$PATH"
echo 'export PATH="$HOME/google-cloud-sdk/bin:$PATH"' >> ~/.bashrc
```

**Windows:** Restart your terminal after installing gcloud.

---

### "Stitch API has not been used in project" Error

Enable the API manually:
```bash
gcloud services enable stitch.googleapis.com --project=YOUR_PROJECT_ID
```

Or visit: `https://console.cloud.google.com/apis/library/stitch.googleapis.com?project=YOUR_PROJECT_ID`

---

### Token Expired / Authentication Error

Refresh your authentication:
```bash
gcloud auth login
```

Or re-run the setup:
```bash
npx -p stitch-mcp-auto stitch-mcp-auto-setup
```

---

### "Connection Refused" After Google Login

This is **normal behavior**. After Google authentication completes, the browser redirects to `localhost:8085` which is a temporary callback server that gcloud uses. Once authentication is complete, this server closes.

**Solution:** Simply close this tab and return to the setup page. It will automatically detect your login.

---

### Browser Doesn't Open Automatically (WSL)

If the browser doesn't open automatically in WSL:

1. Copy the URL shown in the terminal
2. Paste it in your Windows browser manually
3. Complete the login
4. Return to the setup page

---

### Full Reset

If something goes wrong, reset everything:

```bash
# Remove stitch-mcp-auto config
rm -rf ~/.stitch-mcp-auto

# Revoke gcloud credentials
gcloud auth revoke --all

# Re-run setup
npx -p stitch-mcp-auto stitch-mcp-auto-setup
```

> **📋 Role Separation:**
> - **Stitch API (gcloud):** Handles all UI page/screen generation
> - **Antigravity OAuth:** Handles image asset generation (logo, icon, hero images)
>
> Without Antigravity authentication, `generate_design_asset` will return an error. Use Stitch's `generate_screen_from_text` for UI pages.
