How to use camera:ScreenPointToRay inside a serverScript?

Obviously, I can't access the camera inside the serverScript…. does anyone know a way to pass the information on through a RemoteEvent.. I am very new to these remote events. Basically, I am trying to make this code work inside a serverScript:

local ignoreList = 
        {}

        table.insert(ignoreList, player.Character)

        local Debris = game:GetService("Debris")

        local ray = camera:ScreenPointToRay(mouse.X, mouse.y, 1)
        local startPoint = Instance.new("Part", workspace)
        startPoint.Size = Vector3.new(1,1,1)
        startPoint.CFrame = CFrame.new(ray.Origin, ray.Origin + ray.Direction)
        startPoint.Anchored = true
        startPoint.CanCollide = false
        startPoint.Transparency = 1
        startPoint.Name = ("bulletPart")
        Debris:AddItem(startPoint, .05)


        local endPointRay = camera:ScreenPointToRay(mouse.X, mouse.y, 300)
        local endPoint = Instance.new("Part", workspace)
        endPoint.Size = Vector3.new(1,1,1)
        endPoint.CFrame = CFrame.new(endPointRay.Origin, endPointRay.Origin + endPointRay.Direction)
        endPoint.Anchored = true
        endPoint.CanCollide = false
        endPoint.Transparency = 1
        endPoint.Name = ("bulletPart")


        local startBeamRay = Ray.new(startPoint.CFrame.p, (endPoint.CFrame.p - startPoint.CFrame.p).unit * 50)
        local hit, pos = workspace:FindPartOnRayWithIgnoreList(startBeamRay, ignoreList, false, true)
        local dist = (startPoint.Position - pos).magnitude
        local beam = Instance.new("Part", workspace)
        beam.Anchored = true
        beam.CanCollide = false
        beam.Transparency = 1
        beam.BrickColor = BrickColor.new("Cool yellow")
        beam.Size = Vector3.new(.2,.2,dist)
        beam.CFrame = CFrame.new(startPoint.CFrame.p, pos) * CFrame.new(0,0, -dist / 2)
        beam.Name = ("bulletPart")
        local oldPos = pos
        if hit then
            local humanoid = hit.Parent:FindFirstChild("Humanoid")

            if not humanoid then
                humanoid = hit.Parent.Parent:FindFirstChild("Humanoid")

            end

            if humanoid then
                humanoid:TakeDamage(30)
            end
        end
        Debris:AddItem(beam, .08)
        if hit == nil then
            repeat

        local newBeamRay = Ray.new(oldPos, (endPoint.CFrame.p - oldPos).unit * 20)
        local hit, pos = workspace:FindPartOnRayWithIgnoreList(newBeamRay, ignoreList, false, true)
        local dist = (oldPos - pos).magnitude
        local Newbeam = Instance.new("Part", workspace)
        Newbeam.Anchored = true
        Newbeam.CanCollide = false
        Newbeam.Transparency = .25
        Newbeam.BrickColor = BrickColor.new("Cool yellow")
        Newbeam.Size = Vector3.new(.2,.2,dist)
        Newbeam.CFrame = CFrame.new(oldPos, pos) * CFrame.new(0,0, -dist / 2)
        Newbeam.Name = ("bulletPart")
        oldPos = pos
        if hit then
            local humanoid = hit.Parent:FindFirstChild("Humanoid")

            if not humanoid then
                humanoid = hit.Parent.Parent:FindFirstChild("Humanoid")

            end

            if humanoid then
                humanoid:TakeDamage(30)
            end
        end
        Debris:AddItem(Newbeam, .02)
        wait(.03)
        until
        hit ~= nil
        Debris:AddItem(endPoint, .05)
        end

I need that to happen inside a Server script but am not sure how to make that happen... Im sure there are errors in my code too so feel free to say if there is a place I can improve.
