@cloudwerxlab/gpt-image-1-mcp

A Model Context Protocol (MCP) server for generating and editing images using the OpenAI gpt-image-1 model.

🚀 Quick Start

Run this MCP server directly using NPX without installing it. View on npm.

npx -y @cloudwerxlab/gpt-image-1-mcp

The -y flag automatically answers "yes" to any prompts that might appear during the installation process.

📋 Prerequisites

Node.js (v14 or higher)

OpenAI API key with access to gpt-image-1

🔑 Environment Variables

Variable	Required	Description
`OPENAI_API_KEY`	✅ Yes	Your OpenAI API key with access to the gpt-image-1 model
`GPT_IMAGE_OUTPUT_DIR`	❌ No	Custom directory for saving generated images (defaults to user's Pictures folder under `gpt-image-1` subfolder)

💻 Example Usage with NPX

Operating System Command Line Example

Linux/macOS

# Set your OpenAI API key
export OPENAI_API_KEY=sk-your-openai-api-key

# Optional: Set custom output directory
export GPT_IMAGE_OUTPUT_DIR=/home/username/Pictures/ai-generated-images

# Run the server with NPX
npx -y @cloudwerxlab/gpt-image-1-mcp

Windows (PowerShell)

# Set your OpenAI API key
$env:OPENAI_API_KEY = "sk-your-openai-api-key"

# Optional: Set custom output directory
$env:GPT_IMAGE_OUTPUT_DIR = "C:\Users\username\Pictures\ai-generated-images"

# Run the server with NPX
npx -y @cloudwerxlab/gpt-image-1-mcp

Windows (Command Prompt)

:: Set your OpenAI API key
set OPENAI_API_KEY=sk-your-openai-api-key

:: Optional: Set custom output directory
set GPT_IMAGE_OUTPUT_DIR=C:\Users\username\Pictures\ai-generated-images

npx -y @cloudwerxlab/gpt-image-1-mcp

🔌 Integration with MCP Clients

🛠️ Setting Up in an MCP Client

Step 1: Locate Settings File

For Roo: c:\Users\<username>\AppData\Roaming\Code\User\globalStorage\rooveterinaryinc.roo-cline\settings\mcp_settings.json
For VS Code MCP Extension: Check your extension documentation for the settings file location
For Cursor: ~/.config/cursor/mcp_settings.json (Linux/macOS) or %APPDATA%\Cursor\mcp_settings.json (Windows)
For Augment: ~/.config/augment/mcp_settings.json (Linux/macOS) or %APPDATA%\Augment\mcp_settings.json (Windows)
For Windsurf: ~/.config/windsurf/mcp_settings.json (Linux/macOS) or %APPDATA%\Windsurf\mcp_settings.json (Windows)

Step 2: Add Configuration

Add the following configuration to the mcpServers object:

{
  "mcpServers": {
    "gpt-image-1": {
      "command": "npx",
      "args": [
        "-y",
        "@cloudwerxlab/gpt-image-1-mcp"
      ],
      "env": {
        "OPENAI_API_KEY": "PASTE YOUR OPEN-AI KEY HERE",
        "GPT_IMAGE_OUTPUT_DIR": "OPTIONAL: PATH TO SAVE GENERATED IMAGES"
      }
    }
  }
}

Example Configurations for Different Operating Systems

Operating System Example Configuration

Windows

{
  "mcpServers": {
    "gpt-image-1": {
      "command": "npx",
      "args": ["-y", "@cloudwerxlab/gpt-image-1-mcp"],
      "env": {
        "OPENAI_API_KEY": "sk-your-openai-api-key",
        "GPT_IMAGE_OUTPUT_DIR": "C:\\Users\\username\\Pictures\\ai-generated-images"
      }
    }
  }
}

Linux/macOS

{
  "mcpServers": {
    "gpt-image-1": {
      "command": "npx",
      "args": ["-y", "@cloudwerxlab/gpt-image-1-mcp"],
      "env": {
        "OPENAI_API_KEY": "sk-your-openai-api-key",
        "GPT_IMAGE_OUTPUT_DIR": "/home/username/Pictures/ai-generated-images"
      }
    }
  }

🔄 How It Works

🖼️ Image Generation	✏️ Image Editing
Server receives prompt and parameters Calls OpenAI API using gpt-image-1 model API returns base64-encoded images Server saves images to configured directory Returns formatted response with paths and metadata	Server receives image, prompt, and optional mask For file paths, reads and prepares files for API Uses direct curl command for proper MIME handling API returns base64-encoded edited images Server saves images to configured directory Returns formatted response with paths and metadata

📁 Output Directory Behavior

📂 Storage Location

🔹 Default Location: User's Pictures folder under gpt-image-1 subfolder (e.g., C:\Users\username\Pictures\gpt-image-1 on Windows)
🔹 Custom Location: Set via GPT_IMAGE_OUTPUT_DIR environment variable
🔹 Fallback Location: ./generated-images (if Pictures folder can't be determined)

🗂️ File Management

🔹 Directory Creation: Automatically creates output directory if it doesn't exist
🔹 File Naming: Images saved with timestamped filenames (e.g., image-2023-05-05T12-34-56-789Z.png)
🔹 Cross-Platform: Works on Windows, macOS, and Linux with appropriate Pictures folder detection

🔧 Troubleshooting

🚨 Common Issues

Issue	Solution
🖼️ MIME Type Errors Errors related to image format or MIME type handling	Ensure image files have the correct extension (.png, .jpg, etc.) that matches their actual format. The server uses file extensions to determine MIME types.
🔑 API Key Issues Authentication errors with OpenAI API	Verify your OpenAI API key is correct and has access to the gpt-image-1 model. Check for any spaces or special characters that might have been accidentally included.
🛠️ Build Errors Issues when building from source	Ensure you have the correct TypeScript version installed (v5.3.3 or compatible) and that your `tsconfig.json` is properly configured. Run `npm install` to ensure all dependencies are installed.
📁 Output Directory Issues Problems with saving generated images	Check if the process has write permissions to the configured output directory. Try using an absolute path for `GPT_IMAGE_OUTPUT_DIR` if relative paths aren't working.
