Important Note for Cline Users

When using this DALL-E MCP server with Cline, it’s recommended to save generated images in your current workspace directory by setting the saveDir parameter to match your current working directory. This ensures Cline can properly locate and display the generated images in your conversation.

Example usage with Cline:

{
  "prompt": "A tropical beach at sunset",
  "saveDir": "/path/to/current/workspace"
}

Usage

Running the Server

# Run the server
node build/index.js

Configuration for Cline

Add the dall-e server to your Cline MCP settings file inside VSCode’s settings (ex. ~/.config/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json):

{
  "mcpServers": {
    "dalle-mcp": {
      "command": "node",
      "args": ["/path/to/dalle-mcp-server/build/index.js"],
      "env": {
        "OPENAI_API_KEY": "your-api-key-here",
        "SAVE_DIR": "/path/to/save/directory"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

Make sure to:

1. Replace /path/to/dalle-mcp-server/build/index.js with the actual path to the built index.js file
2. Replace your-api-key-here with your OpenAI API key
