If i get the mouse in a local script, is there a way to transfer that to a server one?

This is the server script, and recently i have found that the mouse cannot be gotten inside of it, is there a way to transfer an already defined mouse from a local to the server script?

Here's my script:

wait()
local event = script.Parent



event.OnServerEvent:Connect(function(player)


    local anim = player.Character.Humanoid:LoadAnimation(script.Charge)

    anim:Play()

local darknebula = Instance.new("Part")
darknebula.Shape = "Ball"
darknebula.Parent = player.Character.RightHand
darknebula.Size = Vector3.new(35, 35, 35)
darknebula.Color = Color3.fromRGB(0, 0, 0)
darknebula.Material = "Neon"
darknebula.Name = "darknebula"
darknebula.Massless = true

local weld = Instance.new("Weld")
weld.Name = "Weld"
weld.Parent = darknebula
weld.Part1 = darknebula
weld.Part0 = player.Character.RightHand
weld.C0 = CFrame.new(0, 0, 0)
weld.C1 = CFrame.new(0, 35, 0)



local bg = Instance.new("BodyGyro",player.Character.UpperTorso)
bg.Name = "skillgyro"
bg.D = 100
bg.MaxTorque = Vector3.new(math.huge, math.huge, math.huge)

local bp = Instance.new("BodyPosition",player.Character.UpperTorso)
bp.Name = "skillposition"
bp.Position = player.Character.HumanoidRootPart.Position
bp.MaxForce = Vector3.new(math.huge, math.huge, math.huge)

local mouse = player:GetMouse()
local Pos = mouse.CFrame
bg.CFrame = CFrame.new(player.Character.UpperTorso.Position,Pos)
