My MCP server responds with:
```
{
“content”: [
{
“type”: “image”,
“mimeType”: “image/jpeg”,
“data”: “(raw base64)”
}
]
}
```
This is exactly as described in the spec (section 5.2.2).
I’m using the responses API and chatgpt keeps saying that “action ‘get_image’ returned no result’. I verified with the MCP inspector tool and with claude and it works fine. The image is 18KB, so it’s not large.
I also tried to return a resource link but it also didn’t work.
Are MCP image responses supported?
