01
Schema system
Entities, offsets and fields resolved through the schema the game itself ships — not through headers that rot on the next update.
Source 2 · C++ · Server side
Direct access
to Source 2.
No compromises.
A plugin framework for Counter-Strike 2 that keeps you at engine level. Schema-based entities, game hooks, KHook detours and native events — in C++, with nothing between your code and the game.

01 — Capabilities
Built for engine-level development, not scripting
Every subsystem is a thin, deliberate layer over the engine, and all of them ship in the box. Use the high-level API where it saves you time, and drop straight to memory where it does not.
02
Game hooks
TakeDamage, CanAcquire, PostThink, movement, jumps — about 35 game functions the core hooks from its own gamedata. A handler and a context, no signature of your own, and a plugin that survives an engine update with a core update.
03
Hooks on KHook
Virtual, vtable and function detours on the one KHook engine Metamod runs, so the core, every plugin and Metamod itself compose correctly — for everything the game hooks do not cover.
04
Commands & ConVars
Console and chat commands, listeners on commands the game already owns, typed ConVar refs with replication.
05
Events & GameEvents
A fully typed game event system on top of engine-level events, hooked pre or post with the usual KHook::Action vocabulary.
06
Memory & addresses
Raw pointers, module handles, GameConfig signatures and resolved engine functions like spawn, set model and take damage.
07
Scheduler & tracing
Timers, next-frame execution, and ray and collision trace utilities shipped with the toolkit.
08
Menus & custom HUD
Chat menus with options, titles and per-player state, plus click callbacks on custom HUD layout entities.
09
Network messages
Allocate, send and hook Source 2 net messages by numeric ID or by partial name — protobuf included.
10
Sounds
Sound events sent to exactly the players you pick, stopped or re-parametrised by guid, per-player volume channels, and a hook on every sound the game sends.
11
Transmit
Per-viewer entity visibility: hide players and entities from some clients and not others, owner-following, and a CheckTransmit hook for the rest.
12
HTTP, JSON & MySQL
Async requests through Steam, a JSON value API and typed MySQL result sets, so you do not vendor three libraries first.
02 — Documentation
Pick the part of the engine you are working on
Guides for every subsystem, a reference generated from the SDK headers, and the full schema of the game — each with a sidebar of its own.

03 — In practice
The same API you would have written yourself
Work like you are inside the engine
Controllers, pawns and schema fields are generated from the game itself. Read and write them exactly like native code — with or without automatic SetStateChanged.
- Schema-based access
- Automatic networking
- Zero wrappers

04 — Quickstart
Three steps to a loaded plugin
- 01
Install MetaMod:Source
Source2Toolkit loads through MetaMod. Drop it into /game/csgo/ and register it in gameinfo.gi.
Game csgo/addons/metamod - 02
Drop in the toolkit
Extract the release and copy the /addons directory into your server /game/csgo/ folder.
/game/csgo/addons/source2toolkit - 03
Verify and build
Restart the server, confirm the plugin is loaded, then start writing against the API.
