See what’s connected, what’s ready, and what to do next.

A Mono development fork of Roblox Executor MCP, starting with clearer status for you and the AI using it.

The local dashboard reports the server running, no AI or Roblox clients connected, and semantic search setup required. Each connection step has its own status and setup action.
The actual dashboard, before connecting a Roblox client.

What changed

One place to check readiness

Server health, AI connections, Roblox clients, source sync, and semantic search have separate states. A running server no longer looks offline just because Roblox isn’t connected.

A clear first call for the AI

get-session-status returns structured readiness and target information, even with no Roblox client. It reads status without executing code or starting indexing.

A useful next step

Open Roblox connection instructions, connect your AI app, or configure semantic search from the status panel. Failed checks replace stale connection information.

Honest connection states

“Configured” doesn’t mean a provider was tested. Missing or ambiguous clients are reported explicitly, with no silent switch to another client.

Run it locally

This download contains source code. You’ll need Node.js and npm; the package declares Node 22.23.4+, 24.22.1+, or 26.12.1+ within those major versions.

Use only with experiences and clients you own or are authorized to inspect.

  1. Download and extract

    Open a terminal in the extracted roblox-mcp folder.

  2. Install and build

    npm ci --ignore-scripts
npm run build

    The generated connector is included. Rebuilding the connector itself also needs Darklua.

  3. Start the local server

    npm run start:core

    Open localhost:16384. Use Connect AI app to configure your app and Add Roblox client for connection instructions.

  4. Check the connection

    Ask your AI to call get-session-status. If you have multiple clients, choose a client explicitly before an inspection call.

Release details

Stage
Shared readiness · Development preview
Validation
Build and 21 focused tests passed. Desktop and phone-width dashboard checked. No live Roblox session was tested.
Upstream
upio/roblox-executor-mcp at b48f49c. Original authorship and MIT license retained.
Next
Verified onboarding, authenticated transport access, and clearer operation outcomes.

This stage improves diagnostic UX. Upstream execution and transport behavior remain; access controls are still pending. Keep the local bridge on a trusted network. This website hosts the project’s source, not a running MCP server.

The full upstream test suite also needs Darklua and Luau, and currently references benchmark files absent from its public checkout. The focused checks above don’t establish full-suite or live-game compatibility.
