        "GITHUB_TOKEN": "your_github_token_optional",
        "ALPHA_VANTAGE_API_KEY": "your_alpha_vantage_key_optional"
      }
    }
  }
}
```

5. **Restart Claude Desktop**

## 🔧 API Keys & Security Configuration

### 🔒 Secure API Key Management

**IMPORTANT**: Never hardcode API keys in your configuration. Use environment variables for security.

### Required for Financial Tools
- **Alpha Vantage**: Free tier available at [alphavantage.co](https://www.alphavantage.co/)

### Optional for Enhanced Features
- **GitHub Token**: For higher rate limits
- **Google Custom Search**: For backup search functionality

### 🛡️ Secure Configuration Methods

**Method 1: Environment Variables (Recommended)**
```bash
# Set environment variables
export ALPHA_VANTAGE_API_KEY="your_key_here"
export GITHUB_TOKEN="your_token_here"

# Then use in Claude Desktop config without exposing keys
{
  "mcpServers": {
    "open-search-mcp": {
      "command": "node",
      "args": ["path/to/dist/expanded-server.js"]
    }
  }
}
```

**Method 2: .env File (Local Development)**
```bash
# Create .env file (automatically ignored by git)
echo "ALPHA_VANTAGE_API_KEY=your_key_here" >> .env
echo "GITHUB_TOKEN=your_token_here" >> .env
```

**Method 3: Claude Desktop Environment (Less Secure)**
```json
{
  "mcpServers": {
    "open-search-mcp": {
      "command": "node",
      "args": ["path/to/dist/expanded-server.js"],
      "env": {
        "ALPHA_VANTAGE_API_KEY": "your_key_here",
        "GITHUB_TOKEN": "your_token_here"
      }
    }
  }
}
```
