How to report issues with Claude Desktop

[rsbohn]

My MCP server provides a small 64x64 thumbnail as a base64 encoded string.
Claude Desktop receives the thumbnail, but when I ask to see it responds, "I've already displayed it".
I have a minimal python script to replicate the issue.

How do I report the issue to Anthropic?
