Implementation Reference

• server.py:17-23 (handler)

  MCP tool handler for 'get_task_by_id' registered with @mcp.tool(). It calls TaskService.get_task_by_id and handles not found case.

  @mcp.tool()
  async def get_task_by_id(task_id: str) -> dict[str, Any]:
      """Get details for a specific task by ID."""
      task = service.get_task_by_id(task_id)
      if not task:
          return {"error": "Task not found"}
      return task

• deltatask/services/task_service.py:116-125 (helper)

  TaskService helper method that retrieves task by ID from repository, adds subtasks recursively, and returns the task or error.

  def get_task_by_id(self, task_id: str) -> Dict[str, Any]:
      """Get a specific task by ID with its subtasks."""
      task = self.repository.get_todo_by_id(task_id)
      if not task:
          return {"error": "Task not found"}
      
      # Add subtasks
      self._recursively_add_subtasks(task)
      
      return task
