## Installation

### Prerequisites
- Python 3.10 or higher
- Google Cloud Project with Workspace APIs enabled
- OAuth 2.0 credentials

### Step 1: Clone and Setup

```bash
# Clone the repository
git clone https://github.com/YOUR_USERNAME/google-workspace-mcp.git
cd google-workspace-mcp

# Create virtual environment
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt
pip install -e .

# Create config directory
mkdir -p config
```

### Step 2: Google Cloud Console Setup

1. Go to [Google Cloud Console](https://console.cloud.google.com/)
2. Create a new project or select existing one
3. Enable the following APIs:
   - Google Drive API
   - Google Docs API
   - Google Sheets API
   - Google Slides API
   - Google Forms API
   - Gmail API

4. Configure OAuth Consent Screen:
   - Go to "APIs & Services" > "OAuth consent screen"
   - Choose "External" user type
   - Fill in required fields (App name, User support email, Developer contact)
   - Add scopes:
     - `https://www.googleapis.com/auth/drive`
     - `https://www.googleapis.com/auth/documents`
     - `https://www.googleapis.com/auth/spreadsheets`
     - `https://www.googleapis.com/auth/presentations`
     - `https://www.googleapis.com/auth/forms`
     - `https://www.googleapis.com/auth/gmail.modify`

5. Create OAuth 2.0 Client ID:
   - Go to "Credentials" > "Create Credentials" > "OAuth client ID"
   - Choose "Desktop app" as application type
   - Download credentials JSON file
   - Copy `config/credentials.json.example` to `config/credentials.json`
   - Replace the example values with your downloaded credentials

### Step 3: Initial Authentication

```bash
# Run server for first-time authentication
python3 -m google_workspace_mcp

# Browser will open for OAuth consent
# Grant necessary permissions
# Token will be saved automatically
```

### Step 4: Claude Code Integration

Add to your Claude Code MCP settings (`~/.claude/config/settings.json`):

```json
{
  "mcpServers": {
    "google-workspace": {
      "command": "/usr/local/bin/python3",
      "args": ["-m", "google_workspace_mcp"],
      "cwd": "/path/to/your/google-workspace-mcp",
      "env": {}
    }
  }
}
```

**Note**: Replace `/path/to/your/google-workspace-mcp` with your actual installation path.

```

### Cache Settings
Default cache TTL: 300 seconds (5 minutes)
Max cache size: 1000 items

### Rate Limiting
Default limits:

## Troubleshooting

### Authentication Issues
```bash
# Clear stored tokens
rm ~/.config/gw-mcp/token.pickle

# Re-authenticate
python3 -m google_workspace_mcp
```

### Permission Errors
- Verify all required APIs are enabled in Google Cloud Console
- Check OAuth scopes in consent screen configuration
- Ensure credentials.json is in correct location

### Rate Limit Errors
- Server automatically handles rate limiting with exponential backoff
- Check Google Cloud Console quotas if persistent issues

### Import Errors
```bash
# Reinstall dependencies
pip install -r requirements.txt --force-reinstall
```

## Development

### Running Tests

## Security Considerations

- **Token Storage**: Tokens encrypted and stored securely in user config directory
- **Scope Minimization**: Only requests necessary permissions
- **No Credential Logging**: Sensitive data never logged
- **Automatic Token Refresh**: Expired tokens refreshed automatically
- **Rate Limiting**: Prevents quota exhaustion and API abuse
