Summary
Editing is the half that matters, and most image wrappers skip it.
Generation gets you something close; editing gets you the thing you asked for. Being able to hand back an image and describe the change — rather than re-rolling a prompt and hoping — is the difference between a toy and a tool you use twice. Costs land on your own OpenAI key, so the spending is visible where you already watch it.
What it is
A tool server over OpenAI's image generation and editing endpoints, exposing the editing half rather than generation alone.
What you get
- Image generation from a prompt
- Editing an existing image rather than regenerating it
- Advanced prompt control over the request
Requirements
An OpenAI API key, and npx to run it. MIT licensed.
Setup effort
One command plus a key — npm install -g openai-gpt-image-mcp-199bio, then supply credentials
