Authorised Territory demonstrates a .NET MCP server pattern where a tool call starts a background task and returns a task handle instead of an immediate result, while a .NET client polls the server every second until the final output is available.

Overview

The video shows how to implement an MCP server in .NET that exposes a tool designed for long-running work:

When the client invokes the tool, the server starts the work as a background task.
Instead of returning the final result immediately, the server returns a task reference/handle.
A .NET client then polls the MCP server every second until the tool reports completion and returns the final result.
