OpenAI GPT Image

Generate and edit images with OpenAI's image models — and get files back instead of oversized base64.

LABSCO SUMMARY

It handles the failure everyone else hits on image two.

Clients cap a tool response at 1MB, and a couple of high-resolution images blow straight past that as base64 — the error is unhelpful and the fix is not obvious. Switching to file output above the threshold is the whole difference between a demo and something you can use on real work, and it is why the absolute-path and writable-directory rules are worth reading before the first run.

What it is

An MCP server over OpenAI's image generation and editing APIs, usable against api.openai.com or an Azure OpenAI deployment. Two tools, a lot of options, and one piece of plumbing that matters more than it sounds.

What you get

  • create-image — text to image with size, quality and background options, and n up to 10 images in a single call
  • edit-image — inpainting, outpainting and compositing, taking a file path or base64, with an optional mask that bounds where edits apply
  • Automatic file output: anything over the 1MB tool-response ceiling is written to disk and the path returned, which is what prevents result exceeds maximum length of 1048576
  • Azure OpenAI deployments alongside the standard API
  • An --env-file argument so credentials can come from a file rather than the client config

Requirements

OPENAI_API_KEY, or the Azure trio AZURE_OPENAI_API_KEY, AZURE_OPENAI_ENDPOINT and OPENAI_API_VERSION. Image API access needs a verified OpenAI organization, and after verifying it can take 15–20 minutes to activate. Built from source with yarn install and yarn build, then run as node dist/index.js. MCP_HF_WORK_DIR sets where saved images land, defaulting to /tmp. File paths passed in must be absolute, and the output directory must be writable.
