Can you aim a tool without a local script?

I need to aim a tool towards where the player clicks.

I have this script here in local

local tool = script.Parent
local mouse = game.Players.LocalPlayer:GetMouse()

function pew()
    wait (.01)
local arrow = script.Parent.needle
    arrow.CFrame = CFrame.new(tool.Handle.Position, mouse.Hit.p) --like this, where the tool does something in the direction of your mouse click

end
tool.Activated:connect(pew)

There is a script in server which does the rest but i'm certain it works fine, but i'll provide it anyways.

local tool = script.Parent
local bullet = game.ReplicatedStorage.bullets.needle 
local sound = tool.Sound


function pew()
sound:Play()
local arrow = bullet:clone() 
arrow.Parent = tool 
game:GetService("Debris"):AddItem(arrow, .22)
    local v = Instance.new ("BodyVelocity", arrow)
v.velocity = arrow.CFrame.lookVector *90
v.maxForce = Vector3.new(math.huge, math.huge, math.huge)
tool.ManualActivationOnly = true
wait (.3)
tool.ManualActivationOnly = false
end

tool.Activated:connect(pew)

But it only works in studio because of the whole localscript interacting with server objects thing.

Is there a way I could aim the tool using a server script?

I could probably turn off filtering to make it work, but I would like to keep that on since it helps with learning to script good.
