DALL-E MCP server

This MCP server integrates OpenAI's DALL-E image generation capabilities with Roo Code and other MCP-compatible AI assistants. It provides full access to all DALL-E API options, allowing for fine-grained control over the image generation process through the Model Context Protocol.

Installation

Global Installation

Install the package globally using npm:

npm install -g openai-mcp

Run the setup command to configure it with Roo Code:

openai-mcp install

API Key Configuration

For the server to function properly, you need to set up your OpenAI API key:

1. Open Roo Code
2. Navigate to Settings
3. Add the following environment variable to the MCP server configuration:

"openai-mcp": {
  "env": {
    "OPENAI_API_KEY": "your-openai-api-key"
  }
}

4. Restart Roo Code for the changes to take effect

Usage

Basic Image Generation

Once installed, you can generate images by using the DALL-E tool in your AI assistant. The basic syntax involves providing a prompt that describes the image you want to generate.

Example prompt:

Generate an image of a sunset over mountains

Advanced Options

The DALL-E integration supports all available API options for fine-tuned control:

Image Size

Specify the dimensions of the generated image:

• size: "1024x1024" (default), "1024x1792", or "1792x1024"

Image Quality

Control the quality of the generated image:

• quality: "standard" (default) or "hd"

Image Style

Set the stylistic emphasis:

• style: "vivid" (default) or "natural"

Model Selection

Choose which DALL-E model to use:

• model: "dall-e-3" (default) or "dall-e-2"

Example with Options

To generate an image with specific options, you can include them in your request:

Generate an image of a futuristic cityscape with flying cars
Size: 1792x1024
Quality: hd
Style: vivid

Troubleshooting

If you encounter issues with the MCP server:

• Verify your OpenAI API key is correct and has access to DALL-E
• Check that Roo Code is properly configured with the environment variables
• Ensure you have a stable internet connection
• Restart the MCP server if it becomes unresponsive

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "openai-mcp" '{"command":"npx","args":["-y","openai-mcp"],"env":{"OPENAI_API_KEY":"your-openai-api-key"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "openai-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "openai-mcp"
            ],
            "env": {
                "OPENAI_API_KEY": "your-openai-api-key"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "openai-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "openai-mcp"
            ],
            "env": {
                "OPENAI_API_KEY": "your-openai-api-key"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
