MCP-OpenAI-ImageAPI

A Model Context Protocol (MCP) server for generating and editing images using OpenAI’s GPT-Image-1 API. This project provides an API interface to generate or edit images based on text prompts and input images, with results stored and served via an S3-compatible object storage server.

Features

• Generate images from text prompts using OpenAI’s GPT-Image-1
• Edit images based on prompts and input images
• Asynchronous FastAPI-based MCP server
• Automatic upload and retrieval of images from object storage

Requirements

• Python 3.8+
• OpenAI API key
• Access to an S3-compatible object storage server (e.g., MinIO, AWS S3, or self-hosted)

Note: You must provide your own S3-compatible object storage server. This project include an very simple object storage backend.

The server exposes a tool gpt-image-generator for generating or editing images. See the code for API details.

Configuration

• Set your OpenAI API key as an environment variable: OPENAI_API_KEY
• Configure your S3-compatible object storage credentials as required by your storage server implementation.
