Magnetar plugins

Anti-Cheat is a Magnetar server plugin for Space Engineers dedicated servers. It adds configurable server-side enforcement around malformed client RPCs, validation failures, oversized payloads, and admin creative-tool activity. Current protections include toolbar request validation, camera-setting bounds, GPS and faction payload length caps, social-list and known-sector overflow guards, and escalation for repeated validation failures. The admin audit module logs creative tools toggles, creative/admin block placement, and creative-mode welding activity so staff actions leave a clear server-side trail.

BlockLimits is a Space Engineers dedicated server plugin for Magnetar that enforces block limit rules by player, faction, and grid. It checks blocks as they are built or welded from a projection, and checks pastes and merges as a whole: a paste or merge that would go over a limit is refused. It also limits the blocks per grid and the small and large grids per player, can import the vanilla block type limits, and has !blocklimit chat commands for inspecting and managing limits in-game. Built on the Magnetar PluginSdk with its config UI rendered by Quasar, it also exposes a cross-plugin API (BlockLimits.PluginApi.Limits.CanAdd) that other plugins can call to gate block placement against the configured limits. Functionality is inspired by and reimplements the original Torch plugin BlockLimiter by N1Ran: https://github.com/N1Ran/BlockLimiter

Concealment cuts dedicated server load by concealing grid groups that are far from every online player. Concealed grids stop simulating, so their timers, programmable blocks and thrusters pause. They are revealed again when a player comes near. Admins set the conceal and reveal distances and scan intervals, the block subtypes that keep a grid group revealed, and whether pirate grids may be concealed. Active refineries and assemblers follow a production mode: Off keeps them revealed, Conceal pauses them, and Approximate lets them catch up at boosted speed after they are revealed. Dynamic rules skip selected block updates while no matching characters or grids are nearby. An optional remote control action keeps a grid revealed for one conceal interval. Commands: !conceal run, !conceal reveal, !conceal reveal all, !conceal on and !conceal off. Functionality is inspired by and reimplements the original Torch plugin Concealment by TorchAPI: https://github.com/TorchAPI/Concealment

Essentials is a Magnetar server plugin for Space Engineers dedicated servers that bundles a broad set of quality-of-life and admin tools, all configured through the Magnetar PluginSdk with the config UI rendered by Quasar. It adds ship repair (!fixship), PCU and ownership transfer and inspection (!transfer, !pcu), economy management with player-to-player payments (!econ), bulk block enable/disable/removal (!blocks) and auto-commands. Server features include a customizable MOTD with optional Steam overlay links, stopping all ships on startup, automatic empty-backpack cleanup, owned-grid GPS listing, and optional matchmaking tag filtering. Harmony patches are guarded with the EnsureCode attribute so they fail-safe when Space Engineers ships an update that changes patched methods. Functionality is inspired by and reimplements the original Torch plugin Essentials by TorchAPI: https://github.com/TorchAPI/Essentials

Magnetar server plugin. Copies faction relations to human members, including offline members, and broadcasts exact reputation totals using SE's native protocol. No client plugin or mod required. Configure enablement and interval through Quasar.

GameServerAuth connects Space Engineers dedicated servers to the Game Server Auth service. Players link Discord and Steam accounts, then authorize in-game with chat commands. Server owners can manage role-based join access, promotion levels, and reserved slots from the web control plane. Native cluster nodes report stable per-node identities automatically.

GridBackups is a Magnetar server plugin that exports ship and station grid blueprints on configurable triggers — interval, steady-state, change thresholds, and pre-concealment. Standalone backups use Quasar data by default; cluster backups use Magnetar PluginSdk shared storage automatically. Supports connected-grid grouping, owner-named folders, NPC/nobody filtering, retention limits, the !gridbackup chat commands, and an external API for other plugins to request backups directly. Functionality is inspired by and reimplements the original Torch plugin GridBackup by LordTylus (license: Apache-2.0): https://github.com/LordTylus/SE-Torch-Plugin-ALE-GridBackup

Hangar is a server-side Space Engineers plugin for Magnetar that lets players store grids in a personal hangar and retrieve them later. With the !hangar (!h) chat commands players can save the grid they are looking at or one named explicitly, list their stored grids with block and PCU summaries, view detailed grid info, load a grid back into the world near themselves or at its original position (moved aside if something took the spot), and delete entries; admins can toggle the plugin and check its status. Configurable options include per-player slot limits, save cooldowns, block and PCU caps per entry, optional inclusion of connected subgrids, ownership transfer on load and majority-ownership checks. Cluster processes use Magnetar PluginSdk shared storage automatically; standalone storage can use a configured path. The PluginSdk UI is rendered by Quasar. Functionality is inspired by and reimplements the original Torch plugin QuantumHangar by Casimir255 (license: Apache-2.0): https://github.com/Casimir255/QuantumHangar)

Server-side plugin for Multigrid Projector. Enables full multigrid projection welding and repair for all players on the server. Install it via Quasar (the Magnetar control plane), or into a standalone Magnetar by editing its profile. Configure it remotely from Quasar.

Section editing and cutaways for the players of a dedicated server. Players need the Sections client plugin from PluginHub. With this companion they can copy, cut, delete and blueprint grid sections on the server, and blocks they hide with cutaways or auto-hide lose collision for their own character only. Other players keep seeing and bumping into those blocks. Clients only send requests; every check runs on the server. Admins only by default. The access levels for editing, for removing collision and for using other players' grids are in Sections.cfg in the instance folder.

*** WARNING — REMOTE CODE EXECUTION *** The bearer token = root password. Any client with it can run arbitrary C# on the dedicated server host (file I/O, processes, native [DllImport]). Never share or screenshot it; never port-forward the listener. Serves localhost only. Turns your Space Engineers Dedicated Server into an MCP (Model Context Protocol) server. An LLM like Claude can connect over HTTP and execute C# directly in the running server engine with full .NET and game API access. Features: - REPL-style: no boilerplate, Roslyn 5.3, [DllImport] supported - All assemblies referenced (.NET + game + plugins) incl. internal members - Lanes: main (multi-frame coroutines), parallel (long/blocking work) - Console.WriteLine() piped back to the LLM - Per-field errors with corrected line numbers - Configurable port, auto-generated bearer token Transport: MCP Streamable HTTP (not SSE). POST JSON-RPC to http://localhost:9000/

Undo and redo for the players of a dedicated server, as in single player. Players need the Undo client plugin from PluginHub. The server records what they build, remove, paste, delete, paint and change in the terminal, keeps each player's history in the world save and replays Ctrl-Z / Ctrl-Y here, where removed blocks and deleted grids come back under their old ids with their settings, inventory and links. Clients only ask for steps; every check runs on the server. Only for players with creative tools enabled, or in a creative world. The grid history (Ctrl-H) lists each player's backed up grids from the server's grid store, with a budget per player and for all players.

Experimental Unified Storage companion for Magnetar. Provides authenticated, revisioned world-local profiles with paging and recovery tools; optional authoritative transfers and rebalance; owner-controlled refinery, component and loadout services; and cancellable idle-assembler-drain jobs. Operator settings use Magnetar PluginSdk. Server mutation capabilities default off and unattended services also require explicit profile-owner opt-in. The client remains usable without the companion. Full multiplayer gameplay acceptance is pending; use a test server first.
