GMToolbox - Uncrashable Prop Protection + Exploit Detector

GMToolbox - Uncrashable Prop Protection

Built to replace all existing commercial alternatives as the new industry standard.Plug and play uncrashable prop protection, with future presets sharing methods (and default presets). Mainly to be used by DarkRP servers, but can very well be used on Sandbox or any other Sandbox derived gamemode.

For anyone wondering, French language is supported

Prop Protection

• Full support for all CPPI calls
• Toolgun, Physgun, Damage, Pickup, Punt, Properties, Use, EditVar — full compatibility with other addons
• Granular rank-based permissions
• Fine-tuned access control by rank for tools, entities, and models — not just admin vs user
• Buddy system
• Supports all buddy types, instead of just the basic ones. Open menu via context menu or !buddies command
• No need for model blacklists (optional per rank)
• GMToolbox safely handles huge and complex props automatically without hindering gameplay
• Safe unghosting via Gravity Gun
• Props can be ghosted without frustrating players during normal use
• Resistance against any physics crashes
• With tool overrides + smart collision detections

Performance Optimizations

• Efficient collision tracking using collision pools
• Actions only relevant collisions instead of every entity collision on the server
• Per-player collision tracking
• Limits abuse based on the actual player causing it - more accurate and fair
• Rate-limiting on Physgun, Toolgun & net messages
• Stops expensive lua functions from causing lag
• No global entity scanning
• GMToolbox does not loop over every entity or player on the server every x seconds, keeping performance stable even on large maps
• Optimized looping & caching
• Faster data access for entity size, physics data, ownership, and SteamID64 lookups

Exploit Detection

• Alt account detection
• (Warn, auto-ban, or link bans with main accounts)
• VPN, Proxy, Mobile & GeForce NOW detection
• Fully configurable responses per detection type
• IP tracking
• Notifies when players share the same IP
• Net message rate-limiting
• Stops malicious spam that can lag servers
• Exploit honeypots
• Detects known malicious net messages and creates fake honeypots when needed
• Automatic removal of ULX luarun
• Prevents even superadmins from creating hidden backdoors

Tool Overrides & Restrictions

• Precision Tool Secure Override
• The default Precision Tool is known for causing crashes - GMToolbox fully secures it and adds:

              ・Per-mode permissions (Move, Rotate, Weld, Axis, Ballsocket, etc.)

              ・Crash & abuse prevention

• Stacker Improved Override

              ・Spawn rate limits (like AdvDupe2)

              ・Restrictions on materials, colors, welding, gravity & more

              ・Prevents stacker-based lag & crash exploits

• AdvDupe2 Override

              ・Limits on materials, scaling, parenting, collision groups, and more

• Duplicator Override

              ・Same spawn-rate and safety protections as AdvDupe2

• All sandbox tools that unfreeze multiple entities in 1 tick (like precision)

Collision & Lag Detection

• Collision pool limits

              ・Max collisions per second

              ・Friction & physics stress limits

• Per-player collision monitoring
• Automatically ghosts or freezes props that are causing lag
• Automatic Lag Detector
• When server lag is detected, GMToolbox can temporarily:

              ・Disable prop spawning

              ・Disable toolgun usage

              ・Ghost physgun grabs

              ・Disable entity damage

              ・Detect and ghost props owned by the heaviest-load player

These actions only trigger if lag persists, so normal gameplay is never affected unnecessarily.

Admin UI (VGUI)

A full in-game control panel including:

• Dashboard

              ・Live server metrics

              ・Global utility & moderation tools

• Presets System

              ・Save & load configurations

              ・Multi-server support

• Players Menu

              ・Player performance metrics

              ・Player-specific actions (entity ESP, kick, ban, ghost entities etc.)

You can open this menu by typing !gmt ingame as a superadmin.

Database Support

• SQLite (default)
• MySQL / MySQLOO for multi-server setups

Not Convinced Yet?

If you’re unsure about how GMToolbox will perform or whether it’s right for your server, you can test it live on the dev server.

Simply connect to this server IP 57.128.152.1:27070 (type connect 57.128.152.1:27070 in your gmod console)

Superadmin permissions are available on request, message me on Discord or ask me if I'm by chance on the server, so you can explore all features, admin tools, and security modules firsthand.
