Long-running tasks are an open topic of discussion, and I think MCP intends to address it in the future.
There are a few proposals floating around, but one issue is that you don't always know whether a task will be long-running, so having separate APIs for long-running tasks vs "regular" tool calls doesn't fully address the problem.

I've written a proposal to solve the problem in a more holistic way: https://github.com/modelcontextprotocol/modelcontextprotocol...
