Model Context Protocol for s&box

.NET s&box

[!IMPORTANT] This project is currently under active development.

A Model Context Protocol (MCP) server that enables AI assistants to interact with the s&box editor through real-time WebSocket communication.

This MCP server works in conjunction with the separate s&box Adapter Library to provide seamless integration between AI assistants and your s&box projects.

Prerequisites

Quick Start

Step 1: Install and Run the MCP Server

To get started, make sure you have Docker installed on your system. Cursor users can simply click the button below to install and launch the MCP Server automatically, or you can follow the manual instructions below.

  1. Run the container

    docker run -d -p 8080:8080 --name sbox-mcp-server ghcr.io/suiramdev/sbox-mcp-server:latest

  2. Connect your AI assistant to the running MCP Server

    Install MCP Server

Manual Installation using .NET SDK

  1. Build the server

        dotnet build

  2. Run the server

        dotnet run

  3. Connect your AI assistant to the running MCP Server

    Install MCP Server

Step 2: Install the Adapter Library in s&box

To enable interaction with s&box, you need to install the adapter library. This library allows the MCP Server to communicate with the s&box editor.

  1. Install the Adapter Library from the sbox-mcp-library repository

  2. Follow the setup instructions in the Adapter Library repository to:

    • Install the library in your s&box project through the Asset Library
    • Connect to this MCP Server

[!IMPORTANT] The server must be running for the s&box adapter library to function. Please ensure the server is running before proceeding to the next step.

Usage

Once both this MCP Server and the s&box Adapter Library are installed and connected, you can interact with your s&box editor using natural language through your AI assistant:

"Create a ModelRenderer component on the Cube object"
"Find all game objects named 'Player'"
"Set the Scale property of the Transform component on MainCamera to 2,2,2"
"Remove the Rigidbody component from the Ball object"
"Show me all components attached to the Ground object"

Architecture

This MCP Server acts as a bridge between:

  • AI Assistant ↔ This MCP Server ↔ s&box Adapter Library ↔ s&box Editor

The MCP Server:

  • Receives commands from AI assistants via the Model Context Protocol
  • Translates MCP tool calls into structured WebSocket commands
  • Sends commands to the s&box Adapter Library for execution
  • Returns responses back to AI assistants
