Almost no client, including Claude Dekstop, implements Sampling.
I was so excited to see if I can create a server that used sampling and quickly figured out I can't use it anywhere. Funnily Windsurf hangs forever if you use sampling.

"Sampling is a powerful MCP feature that allows servers to request LLM completions through the client, enabling sophisticated agentic behaviors while maintaining security and privacy."
I think the biggest issue is that it can create loops in the flow of programs that would burn through usage quotas pretty fast. It could also allow for "impersonating" the client what opens up a lot of possibilities.
But yeah, the fact that Claude doesn't even implement this is... telling.
