## About

# sbox-mcp

> **Control Facepunch's s&box engine with Claude.** A plugin that lets any MCP-aware LLM client drive scenes, components, and a running game through natural language. Talk things into existence.

[](https://dotnet.microsoft.com) [](https://sbox.game) [](https://modelcontextprotocol.io)

---

## Features

- **🗺️ Manage projects & scenes** — open, save, and navigate your scene graph from natural-language prompts.
- **✨ Spawn entities & edit world** — place props, configure components, set transforms. No menu hunting.
- **🐛 Run, test & debug** — drive a *running* game from your prompts. Spawn enemies, tweak globals, dump runtime state.
- **🛠️ Edit C# code & resources** — write `Component` scripts, refactor existing ones, tight feedback loop with the editor's hot-reload.
- **🔌 Works with any MCP client** — Claude Code, Cursor, or any LLM client speaking Model Context Protocol.

## Try it

> "Place a red bouncing cube at the camera origin and make it spawn three children when clicked."

> "Write me a `Component` that plays a sound on overlap and attach it to the prop I have selected."

> "While the game is running, spawn 50 zombies in a circle around the player."
