Is it possible to embed files coming from a MCP response? I connect LibreChat to a MCP-Server that can deliver PDF files as response. I would like to have these files embedded in the chat directly, so I can download them. I understood that it works with images (type=image), but what about PDFs?

I looked up here for information https://modelcontextprotocol.io/specification/2025-11-25/server/tools#tool-result but it wasn't realyy enlightening...
