Why WEPPY Roblox AI Toolkit?

AI coding agents like Claude, Codex, and Gemini are powerful, but they cannot see or modify anything inside Roblox Studio. The DataModel, scripts, terrain, and lighting are invisible to external tools. Without a bridge, AI can only generate code snippets that you must paste manually.

The WEPPY MCP Server connects AI agents to the WEPPY Roblox Studio Plugin. AI directly creates and modifies instances, scripts, properties, terrain, and more inside Studio, and the changes are reflected immediately in Studio and the dashboard so you can see exactly what changed.

WEPPY is also built for Roblox experiences that are split across several Places. Open up to five Studio windows for Lobby, Game, Shop, Tutorial, or other Places, then tell the agent which Studio ID to use. One request can update several Places without re-explaining context or copying changes by hand.

For assets, an agent can create or prepare an image, save it to the Asset Library, upload it through Roblox Open Cloud, and apply the returned asset URI to a Place. The result is a shorter path from "make this icon/decal" to "it is visible in Studio."

No copy-pasting code or asset IDs. AI does the work, you review the results.

Quick Install

Start from the web install page. It shows the recommended one-line script for your platform first.

👉 Web Install Page

Recommended One-Line Install

On the install page, copy the one-line script and run it in Terminal or PowerShell.

macOS / Linux

Windows (PowerShell)

Then reopen your AI app and restart Roblox Studio.

Automatic WEPPY MCP Server registration supports Claude Code, Claude Desktop, Cursor, Codex CLI/App, Gemini CLI, and Antigravity / Antigravity IDE / Antigravity CLI. For Claude Code, the installer also installs the WEPPY AI Agent Plugin. For Codex, it adds the plugin marketplace and then asks you to install WEPPY AI Agent Plugin from Plugin Directory. For Antigravity, the AI agent plugin is installed only when Antigravity CLI and agy plugin are available; otherwise the installer preserves the direct MCP connection.

Browser Web Install

If terminal or PowerShell is uncomfortable, use the terminal-free web installer on the same install page.

Manual Install

If the one-line install or terminal-free web installer does not work, register the WEPPY MCP Server manually with your AI app.

Use this server command:

Automatic registration supports Claude Code, Claude Desktop, Cursor, Codex CLI, Codex App, Gemini CLI, and Antigravity / Antigravity IDE / Antigravity CLI.

Any MCP-compatible AI client works. The server command is npx -y @weppy/roblox-mcp@latest.

Dola Desktop connects through a local STDIO Custom Connector. It requires Dola's Pro mode and Local computer. Follow the Dola manual setup guide; the one-line installer and GitHub marketplace plugin do not configure Dola.

Optional WEPPY AI Agent Plugin

The WEPPY Roblox AI Toolkit connects to every supported AI app through the WEPPY MCP Server. Claude Code, Codex, and Antigravity can additionally install the WEPPY AI Agent Plugin for client-native setup and workflow guidance for Studio control, sync, and assets.

Claude Code

Codex

After adding the Codex marketplace, restart Codex, open Plugin Directory, and install WEPPY AI Agent Plugin.

Antigravity

Antigravity CLI is required to install the WEPPY AI Agent Plugin. The one-line installer uses agy plugin install with the latest public GitHub release, verifies it with agy plugin list, and publishes the verified skill-only payload to supported IDE surfaces. Existing installs are replaced on every run so they can converge on the latest release.

The installer reports results as installed, updated, reinstalled, repaired, fallback, failed, or skipped. A missing CLI keeps the shared MCP connection at ~/.gemini/config/mcp_config.json working and reports fallback; an existing plugin is never treated as a skip. In a CLI-only profile, verified native plugin MCP replaces the shared direct WEPPY entry. When Antigravity IDE and CLI coexist, both plugin views stay skill-only and one shared direct weppy-roblox-mcp definition serves both. Outside the verified OS and version matrix, native discovery uses the MCP fallback.

On Windows Antigravity, CLI installation has been verified to expose skills and MCP. Windows Antigravity IDE plugin discovery is unverified because the verified environment has no plugin or skills inspection UI, so the shared MCP fallback is preserved. GitHub URLs are not passed directly to agy plugin install; the installer downloads the latest public release and installs from a prepared local path.
