### 2. Google Cloud Setup

For testing with Steve's project (starry-center-464218-r3):

```bash
# Set your project
gcloud config set project starry-center-464218-r3

# Enable required APIs
gcloud services enable aiplatform.googleapis.com

# Create service account (if not already done)
gcloud iam service-accounts create mcp-vertex-ai \
  --display-name="MCP Vertex AI Service Account"

# Grant necessary permissions
gcloud projects add-iam-policy-binding starry-center-464218-r3 \
  --member="serviceAccount:mcp-vertex-ai@starry-center-464218-r3.iam.gserviceaccount.com" \
  --role="roles/aiplatform.user"

# Generate key
gcloud iam service-accounts keys create credentials.json \
  --iam-account=mcp-vertex-ai@starry-center-464218-r3.iam.gserviceaccount.com
```

For general setup:

```bash
# Create service account
gcloud iam service-accounts create mcp-vertex-ai \
  --display-name="MCP Vertex AI Service Account"

# Grant necessary permissions
gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
  --member="serviceAccount:mcp-vertex-ai@YOUR_PROJECT_ID.iam.gserviceaccount.com" \
  --role="roles/aiplatform.user"

# Download key
gcloud iam service-accounts keys create key.json \
  --iam-account=mcp-vertex-ai@YOUR_PROJECT_ID.iam.gserviceaccount.com
```
### 3. Configuration

Set environment variables:

```bash
export GOOGLE_CLOUD_PROJECT="your-project-id"
export GOOGLE_CLOUD_LOCATION="us-central1"
export GOOGLE_APPLICATION_CREDENTIALS_JSON='{"type":"service_account",...}'
```

Or create a `.env` file:

```env
GOOGLE_CLOUD_PROJECT=your-project-id
GOOGLE_CLOUD_LOCATION=us-central1
GOOGLE_APPLICATION_CREDENTIALS_JSON='{"type":"service_account",...}'
```

### 4. Claude Desktop Integration

Add to your Claude Desktop configuration:

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

```json
{
  "mcpServers": {
    "google-ai": {
      "command": "npx",
      "args": ["@stevekaplanai/google-ai-mcp"],
      "env": {
        "GOOGLE_CLOUD_PROJECT": "your-project-id",
        "GOOGLE_CLOUD_LOCATION": "us-central1",
        "GOOGLE_APPLICATION_CREDENTIALS_JSON": "{...}"
      }
    }
  }
}
```

For testing with mock mode:

```json
{
  "mcpServers": {
    "google-ai": {
      "command": "npx",
      "args": ["@stevekaplanai/google-ai-mcp"],
      "env": {
        "USE_MOCK": "true"
      }
    }
  }
}
```
