RustPlusApi

A C# library for the Rust+ companion API. Query and control your server, render security cameras, listen for FCM notifications, and acquire all the required credentials natively — no Node.js required.

Packages

Package	Downloads	Description
RustPlusApi		Core client. Typed Response<T> API for info/time/map/markers, team & clan chat, nexus auth, entities (smart switch / alarm / storage monitor), and the camera protocol.
RustPlusApi.Fcm		FCM listener — receives server/entity pairing and alarm notifications.
RustPlusApi.Fcm.Registration		Native credential acquisition (GCM/Firebase/FCM/Expo + Steam login + Rust Companion). Replaces the rustplus.js Node CLI.
RustPlusApi.Camera		Camera sessions (CameraController: keep-alive, turret/PTZ helpers, device-kind checks) and frame rendering via ImageSharp.
RustPlusApi.Extensions.DependencyInjection		DI registration (AddRustPlus, IRustPlusFactory) for the core client.
RustPlusApi.Fcm.Extensions.DependencyInjection		DI registration (AddRustPlusFcm, IRustPlusFcmFactory) for the FCM listener.

Versions

Targets .NET Standard 2.0 and .NET 10 — usable from .NET Framework 4.6.2+, .NET 6/7/8/9/10, Mono, and Unity.

Install

dotnet add package RustPlusApi
dotnet add package RustPlusApi.Fcm
dotnet add package RustPlusApi.Fcm.Registration # native credentials (optional)
dotnet add package RustPlusApi.Camera # camera rendering (optional)

Quickstart

1. Get your credentials (once). Run the registration sample — it logs you into Steam, writes rustplus.config.json, and prints the RustPlus(...) arguments after you pair in game:

dotnet run --project samples/RustPlus.Register.ConsoleApp

See samples/ for the full walkthrough. (You can still use npx @liamcottle/rustplus.js fcm-register as a fallback.)

2. Talk to the server:

usingvarrustPlus=newRustPlus(newRustPlusConnection(server,port,playerId,playerToken));awaitrustPlus.ConnectAsync();varinfo=awaitrustPlus.GetInfoAsync();Console.WriteLine(info.Data?.Name);

3. Listen for notifications:

varlistener=newRustPlusFcm(credentials);listener.OnServerPairing+=(_,e)=>Console.WriteLine($"Paired: {e.Data?.Ip}");awaitlistener.ConnectAsync();

Documentation

Full guides and the API reference live on the documentation site (built with DocFX). Start with Getting Started, browse the Recipes for common patterns, or check the Troubleshooting page if something isn't working. Runnable examples are in samples/.
