About This Package

Claude Code integration for the s&box editor.
Anything user-facing in the editor → reachable from the agent. ~593 MCP tools across scene,
inspector, Hammer, ModelDoc, AnimGraph, assets, schema, Roslyn, hotload, physics, audio,
particles, NavMesh - agent can spawn prefabs, drive Hammer cameras, swap entity classes, query the
live API schema, run C# snippets, batch-transform selections, etc.

A docked PTY terminal (View → ClaudeSbox) lets you bring your own harness - Codex, Claude Code,
anything you can run in a shell - straight inside sbox-dev. Three concurrent MCP transports on
127.0.0.1:6790 - HTTP, SSE, stdio bridge - any MCP client connects.

Install

From your sbox-public checkout (git clone --recursive https://github.com/Facepunch/sbox-public),
open a terminal and run:

cd game\addons
git clone https://github.com/coffeegrind123/claude-sbox-setup.git
cd claude-sbox-setup
.\Setup.bat
.\Bootstrap-And-Capture.bat

Launch game\sbox-dev.exe with any project, open the developer console, and run once, ever:

package_install ghage.claude-sbox tools

That's it. The engine patches from the setup repo handle everything from here on - the addon
auto-mounts for every project on every editor restart, with no redownload (files are mirrored to a
global cache at <sbox-public>/game/.sbox-global/cloud/.bin/). The MCP host comes up automatically

Connect Claude Code

claude mcp add --transport http -s user sbox http://127.0.0.1:6790/mcp
(or http://host.docker.internal:6790/mcp if you run Claude Code inside a devcontainer for example)

For stdio-only MCP clients (Claude Desktop, Cline, etc.), use the bundled bridge at
game/addons/claude-sbox-setup/bridge/dist/bridge.js - see the setup repo's README for client
configs.
