Send a narrow client request

remote.OnServerEvent:Connect(function(player, action)
    if action ~= "inspect" then return end
    print("Requester", player.UserId)
end)

The player parameter comes from Roblox; action comes from the client and must be checked.

Server validates and replies narrowly.

local Players = game:GetService("Players")
local storage = game:GetService("ReplicatedStorage")
local request = storage:WaitForChild("InspectRequest")
local feedback = storage:WaitForChild("InspectFeedback")
local nextAllowed = {}
request.OnServerEvent:Connect(function(player, action)
    local now = os.clock()
    if now < (nextAllowed[player.UserId] or 0) then return end
    nextAllowed[player.UserId] = now + 1
    if type(action) ~= "string" or action ~= "inspect" then return end
    feedback:FireClient(player, "Inspection acknowledged")
end)
Players.PlayerRemoving:Connect(function(player) nextAllowed[player.UserId] = nil end)

Client request and local response display.

local storage = game:GetService("ReplicatedStorage")
local request = storage:WaitForChild("InspectRequest")
local feedback = storage:WaitForChild("InspectFeedback")
script.Parent.InspectButton.Activated:Connect(function() request:FireServer("inspect") end)
feedback.OnClientEvent:Connect(function(message) script.Parent.Status.Text = message end)

OnServerEvent is connected on the server; OnClientEvent on the client.

A response RemoteEvent must be replicated so the client can receive it.

This is a bounded learning lab. It has not been executed in an approved Roblox Studio environment by this website.

A checked checklist records your own review, not automated project competence or a community verification.

RemoteEvent crosses the client/server boundary asynchronously. FireServer sends a client request; OnServerEvent receives the real sending Player as its first argument. The remaining payload is untrusted.

FireClient sends feedback to a particular Player. A reply to one requester should not broadcast another player’s private information.

This diagnostic accepts only the fixed request "inspect" and limits it to once per second per player. It grants no reward and does not use client-supplied player identity.
