Weppy Roblox MCP, developed by Hope1026, is a free Model Context Protocol (MCP) server designed to connect AI agents directly to Roblox Studio. Built on Node.js 18+, this tool acts as a real-time bridge, allowing AI to interact with the Roblox Studio DataModel. Distributed via npm, it enables sophisticated AI coding agents like Claude, Codex, Gemini, and Antigravity to manipulate Roblox projects. Developers can automate game element creation, modification, and deletion through natural language commands, significantly enhancing their workflow within the Roblox platform.

What does Weppy Roblox MCP connect to?

Weppy Roblox MCP connects AI agents directly to Roblox Studio. It functions as an MCP server, facilitating real-time communication between various AI clients and the Roblox Studio DataModel. This connection is established through the WEPPY Roblox Studio Plugin. The tool requires a Node.js 18+ runtime environment and is distributed as an npm package. It serves as a bridge, enabling AI to execute commands and manage project elements within the Roblox development environment.

Core features and tools

Weppy Roblox MCP exposes several powerful MCP Tools for AI interaction. These include Instance Management (search, create, delete, clone, move), Properties & Tags (read, modify, manage), and Scripts (read, write, edit). AI can also control Selection, query the Camera, perform Spatial Query, and manage Assets & Environment (lighting, terrain, audio, effects). Additional capabilities cover Playtest functions, Luau Script Execution, UI Studio for in-game UI, and a Roblox Assets guide for asset integration.

Who is it for?

Weppy Roblox MCP targets developers building on Roblox who want to integrate AI agents into their workflow. The audience includes users of AI coding agents such as Claude Code, Claude Desktop, Cursor, Codex CLI/App, Gemini CLI, and Antigravity, specifically for use with Roblox Studio. It empowers these developers to automate complex tasks and manipulate game elements using AI. Skip this if you are not using AI agents for Roblox Studio development.

How to get started

The server authenticates using a WEPPY Pro key or license key for product activation. Full functionality for asset uploads also requires a Roblox Open Cloud API key and Creator ID.

Use cases

• AI agents can directly create, modify, and delete game elements within Roblox Studio using natural language commands.
• AI can route work across up to five connected Roblox Studio windows for multi-place project management.
• AI supports bidirectional project synchronization and asset integration, including generating and uploading assets.

Weppy Roblox MCP offers a direct pathway for AI agents to interact with Roblox Studio, enhancing development efficiency. Its extensive toolset allows AI to manipulate game elements, manage projects across multiple places, and integrate assets directly. The system supports various popular AI coding agents, providing developers with powerful automation capabilities.
