Yep, I agree, I was chatting to one of the Cursor engineers about this, as there are no good examples of this implemented. This is something I will implement once clients have support for it. But it's at the top of my list of improvements.
VS Code supports it since we shipped tools 2 months ago; and it does gracefully fall back for clients that don't support it.
@digitarald Do you have any examples or documentation in terms of what VSCode expects back from the MCP server along with the progress token?
From the spec I linked we show the "message" as our tool calls UX doesn't have a percentage indicator.
The TS SDK doesn't have a progress method, but I am happy to take a stab at adding it here as example.
