What would you like to see?

I was trying to display grafana rendered image received via MCP in anythingLLM chat. I see in anythingLLM logs base64 PNG format recived, but what I get in chat is text description of picture or broken picture icon. I coudn't find in docs or internet clear information if it is possible to display picture or not.

We do not have a callback or render process for images since it can be non-standard. Do you have an MCP you are using right now we can test this against?

I'm sharing repository https://github.com/PiotrRedzinski/basic_grafana_mcp with test scenario description. I could adapt mcp to requirements if specified.

anythingllm log when picture passed as base64 but not displayed (picture is 1x1 pixels, to be sure I did not miss so small picture I tested as well 100x100 with the same result):

@Swatsicle commented on GitHub (Feb 18, 2026):

Hi!

I am also looking for this functionality, as we are using Tableau MCP. The "get-view-image" function returns this:

...RU5ErkJggg==","mimeType":"image/png"}],"isError":false}

Currently, it gets rendered as just text, instead of as an image.

If it's helpful, I can put together a Tableau Cloud-based demo + tableau-mcp config that would let you test this. I can also provide any inputs/outputs from my AnythingLLM instance and logs.

@Swatsicle That might be helpful, what is odd is that the response object for both example MCPs in this thread return two dramatically different types of responses (base64 string, URL for other)

This issue worries me from the infinite maintence we will have to endure as every MCP decides to pass back responses:

  • In various formats with non-standard keys (base64, base64String, dataURI, url)
  • in various schemas, object in array, object, etc etc.

Is there no standard for MCP responses and their fields? I thought there was.

There two options specified in
https://modelcontextprotocol.io/specification/2025-03-26/server/prompts#image-content
{
"type": "image",
"data": "base64-encoded-image-data",
"mimeType": "image/png"
}
or Embedded Resourse ( which can be text/image/audio and has minimal impact on context window)
{
"type": "resource",
"resource": {
"uri": "resource://example",
"mimeType": "text/plain",
"text": "Resource content"
}
}
