OpenAI Image MCP Server

A Model Context Protocol (MCP) server that provides conversational OpenAI image generation capabilities. Generate, edit, and refine images through multi-turn conversations with advanced models like GPT-4o and GPT-4.1.

🎯 What Problems Does This Solve?

Traditional Image Generation Pain Points

❌ Single-shot limitations - "Make it more blue" requires re-describing everything
❌ No conversation memory - Each request starts from scratch
❌ Context loss - Can't reference previous images naturally
❌ Manual workflows - Complex multi-step processes require multiple tools

Our Solution

✅ Conversational refinement - "Make it more blue" works naturally
✅ Session memory - Builds on previous context automatically
✅ Reference awareness - "Use the same style as the previous image"
✅ Integrated workflows - Single interface for complex creative projects

🚀 Key Capabilities

🔄 Session-Based Conversations

# Start a focused session
session = create_image_session("Logo design for tech startup")

# Initial generation
result1 = generate_image_in_session(session_id, "modern tech logo")

# Natural refinement - no need to repeat everything
result2 = generate_image_in_session(session_id, "make it more minimalist")

# Build on context
result3 = generate_image_in_session(session_id, "try it in dark blue")

🔄 Hybrid Workflows

Start simple, expand when needed:

# Quick one-shot for immediate need
result = generate_image("modern office workspace")

# Later, promote to session for refinement
session = promote_image_to_session(
    result["image_path"],
    "Office workspace refinement project"
)

# Continue with conversational context
generate_image_in_session(session_id, "add more plants and warmer lighting")

🚀 Quick Start

1. Installation

Requirements: Python 3.10 or higher

# Install the package
pip install openai-image-mcp

If you need to upgrade Python:

# Using pyenv (recommended)
pyenv install 3.11.8
pyenv global 3.11.8
pip install openai-image-mcp

# Or using Homebrew (macOS)
brew install python@3.11
python3.11 -m pip install openai-image-mcp

For development installation from source, see DEVELOPMENT.md

2. Claude Desktop Integration

Add to your Claude Desktop MCP configuration:

{
  "mcpServers": {
    "openai-image-mcp": {
      "command": "sh",
      "args": [
        "-c",
        "openai-image-mcp 2> mcp_server_stderr.log"
      ],
      "env": {
        "OPENAI_API_KEY": "your_openai_api_key_here"
      }
    }
  }
}

For development setup and alternative configurations, see DEVELOPMENT.md

3. Start Creating

# Create a session for your project
session = create_image_session("Website hero images")

# Generate with natural language
generate_image_in_session(session_id, "modern tech office with diverse team")

# Refine naturally
generate_image_in_session(session_id, "make the lighting warmer")

# Add context
generate_image_in_session(session_id, "create a mobile version of this scene")

🎯 Usage Patterns

📱 Conversational Design Sessions (Recommended)

Best for: Multi-image projects, iterative refinement, brand consistency

session = create_image_session("App icon design")
generate_image_in_session(session_id, "colorful chat app icon")
generate_image_in_session(session_id, "make it more professional")
generate_image_in_session(session_id, "try different color schemes")

⚡ Quick One-Shot Generation

Best for: Immediate needs, single images, uncertain scope

generate_image("professional headshot for LinkedIn")
generate_product_image("wireless headphones", background_type="white")

🔄 Hybrid Start-Simple-Expand-Later

Best for: Testing concepts, uncertain requirements, flexible workflows

# Start quick
result = generate_image("logo concept for bakery")

# Expand when needed
session = promote_image_to_session(result["image_path"], "Bakery brand development")
generate_image_in_session(session_id, "create business card version")

🎨 Example Workflows

Brand Identity Development

session = create_image_session("TechCorp brand identity")

# Logo concepts
generate_image_in_session(session_id, "modern tech company logo")
generate_image_in_session(session_id, "make it more geometric and minimal")

# Expand to brand elements
generate_image_in_session(session_id, "business card design using this logo")
generate_image_in_session(session_id, "website header with the logo")

Product Marketing Suite

session = create_image_session("Wireless headphones marketing")

# Product shots
generate_product_image("premium wireless headphones", angle="45deg")
result = promote_image_to_session(previous_result["image_path"], "headphones campaign")

# Marketing variations
generate_image_in_session(session_id, "lifestyle shot with person using them")
generate_image_in_session(session_id, "create packaging design mockup")
