Implementation Reference

• src/clickup_mcp/tools.py:720-729 (handler)

  Main MCP tool handler implementation for 'delete_task'. Resolves flexible task ID formats and delegates to ClickUpClient.delete_task.

  async def delete_task(self, task_id: str) -> Dict[str, Any]:
      """Delete a task."""
      try:
          # First resolve the task to get the internal ID
          task = await self._resolve_task_id(task_id)
          await self.client.delete_task(task.id)
          return {"id": task.id, "deleted": True}
      except ClickUpAPIError as e:
          return {"error": f"Failed to delete task '{task_id}': {e!s}"}

• src/clickup_mcp/tools.py:140-150 (schema)

  Input schema definition for the 'delete_task' tool, specifying task_id as required string parameter.

  Tool(
      name="delete_task",
      description="Delete a task",
      inputSchema={
          "type": "object",
          "properties": {
              "task_id": {"type": "string", "description": "Task ID to delete"},
          },
          "required": ["task_id"],
      },
  ),

• src/clickup_mcp/tools.py:23-57 (registration)

  Registration of the 'delete_task' handler in the tools dispatch dictionary within ClickUpTools.__init__.
