🔧 Configuring Claude Desktop with MCP Server

To integrate this combined server with Claude Desktop:

Locate the Configuration File:
- Windows: %APPDATA%\Claude\claude_desktop_config.json
- macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Add the following configuration:

{
  "mcpServers": {
    "mcp-3d-cartoon-generator": {
      "command": "node",
      "args": [
        "path/to/your/build/index.js"
      ],
      "env": {
        "GEMINI_API_KEY": "your_gemini_api_key_here",
        "IS_REMOTE": "true",
        "SAVE_TO_DESKTOP": "true",
        "DETECT_OS_PATHS": "true",
        "ALLOWED_DIRECTORIES": "C:\\Users\\YourUsername\\Desktop,C:\\Users\\YourUsername\\Documents",
        "DEBUG": "false"
      }
    }
  }
}

Windows PowerShell Helper Script

For Windows users, you can use the included fix_claude_config.ps1 script to automatically configure Claude Desktop:

Edit the script to update the path to your server build and your Gemini API key
Run the script in PowerShell:

powershell -ExecutionPolicy Bypass -File .\fix_claude_config.ps1

This will create or update the configuration file with proper encoding and settings.

🔒 Security Features

The server implements several security measures:

Path Validation: All file paths are validated to ensure they are within allowed directories.
Allowed Directories: Only directories explicitly set in the ALLOWED_DIRECTORIES environment variable can be accessed.
Symlink Protection: Prevents access to directories outside the allowed scope via symlinks.
Controlled Logging: Debug logs are disabled by default to prevent information leakage.

⚙️ Configuration Options

Environment Variables

Variable	Description	Default
`GEMINI_API_KEY`	Google Gemini API key for image generation	(Required)
`ALLOWED_DIRECTORIES`	Comma-separated list of allowed file system paths	User's home dir, current dir
`IS_REMOTE`	Run in remote mode without browser opening	false
`SAVE_TO_DESKTOP`	Force saving to desktop directory	false
`DETECT_OS_PATHS`	Enable OS-specific path detection	true
`DEBUG`	Enable verbose debug logging	false

🛠️ Troubleshooting

Common Issues:

JSON Parsing Errors in Claude:
- Ensure DEBUG is set to "false" to prevent logs from interfering with JSON communication
- Check for proper JSON formatting in the Claude configuration
File Access Denied:
- Verify that the paths you're trying to access are included in ALLOWED_DIRECTORIES
- Check file permissions on the target files/directories
Images Not Saving:
- Set SAVE_TO_DESKTOP to "true" to ensure images save to the desktop
- Check desktop path detection in the server logs (enable DEBUG temporarily)
