How to Set Up and Use Weppy Roblox
Weppy Roblox MCP Server is a bridge between AI coding agents and Roblox Studio, allowing Claude Code, Cursor, Codex, and Gemini to directly control Roblox Studio through natural language. It installs as both an MCP server and a Roblox Studio plugin, enabling agents to create and modify scripts, generate terrain, manage instance hierarchies, configure lighting and atmosphere, insert assets from the Creator Store, and run automated playtests — all through conversational AI prompts. This dramatically accelerates Roblox game development by letting developers describe what they want and having AI implement it directly in Studio.
Prerequisites
- Node.js 18+ installed
- Roblox Studio installed (Windows 10+ or macOS 12+)
- An MCP-compatible AI client: Claude Code, Claude Desktop, Cursor, Codex, or Gemini CLI
- The Weppy Roblox plugin installed inside Roblox Studio (installed via the setup process)
Install the MCP server (macOS/Linux)
Run the one-line installer script which sets up both the MCP server and prompts you to install the Roblox Studio plugin.
curl -fsSL https://raw.githubusercontent.com/hope1026/weppy-roblox-mcp/main/install.sh | bashInstall the MCP server (Windows PowerShell)
On Windows, use PowerShell to run the equivalent installer script.

}
}
}
}Install the Roblox Studio plugin
Open Roblox Studio and install the Weppy Roblox plugin from the Creator Store or via the plugin marketplace link provided during server setup. The plugin is required to enable bidirectional communication.
Connect Studio to the MCP server
In Roblox Studio, activate the Weppy plugin from the Plugins tab. It will establish a connection to the running MCP server. You should see a 'Connected' status in the plugin panel.
Start building with AI
With Studio connected, open your AI client (Claude Code, Cursor, etc.) and start issuing natural language instructions to modify your Roblox game.

Example prompts for controlling Roblox Studio through the Weppy MCP server.
- "Add particles, a sound effect, and a cooldown timer when the player jumps"
- "Build a boss arena with collision-safe spawn points around the perimeter"
- "Generate procedural terrain with mountains and rivers across a 512x512 stud area"
- "Search the Creator Store for a sword model and insert it into StarterPack"
- "Set up realistic lighting with an atmosphere object and time-of-day cycle"Troubleshooting Weppy Roblox
Roblox Studio plugin shows 'Disconnected' even after starting the MCP server
Ensure the MCP server is running (run npx -y @weppy/roblox-mcp@latest in a terminal to test). The plugin and server communicate on a local port — check that no firewall or antivirus is blocking localhost connections.
npx command fails with a Node.js version error
Weppy Roblox requires Node.js 18 or higher. Run node --version to check and upgrade if needed via nvm install 18 && nvm use 18.
AI agent can see Studio but changes don't appear
Make sure you activated the Weppy plugin inside Roblox Studio from the Plugins ribbon tab. The plugin must be actively running in Studio for the bidirectional sync to work.
