BloxBot

AI-assisted Roblox development. BloxBot is a free, open-source desktop app that connects any AI model to Roblox Studio's official MCP server, so you can build games by describing what you want.

What it does

• Chat with AI models (Claude, GPT, Gemini, and more) that can read and modify your Roblox Studio project in real time
• Create scripts, build UI, manipulate the explorer hierarchy, edit properties - all through natural language
• Uses Roblox Studio's built-in MCP server, giving the AI structured access to Studio. No plugins to install
• Bring your own API key from any supported provider, or connect via OAuth

How it works

BloxBot connects two things:

1. A desktop app (Tauri v2 - React frontend, Rust backend) where you chat with AI
2. An AI server (OpenCode) that manages model connections, sessions, and tool use

The AI connects to Roblox Studio through its official built-in MCP server. When you type a message, the AI uses MCP tools to directly inspect and modify your open Studio project.
