Question

A developer builds an MCP tool that generates images using Stable Diffusion. The tool takes a prompt and returns a base64-encoded image. Claude then describes the image to the user. However, Claude's descriptions don't match the generated images because Claude can't actually see the tool output as an image. How should this be architected?

Accepted Answer

Answer

A. Have Claude generate the image description from the original prompt without seeing the actual image

Answer

B. Have the tool return a text description of what it generated alongside the image

Answer

C. Store the image and return a URL that Claude mentions to the user
