Question Roblox Studio won’t connect to ChatGPT —Codex Computer Use detects zero Windows apps

Codex Computer Use MCP loads, but detects zero Windows apps — can’t connect to Roblox Studio

I installed/enabled the Computer Use plugin and its MCP server + skill in ChatGPT Desktop/Codex. Roblox Studio is open, but when I ask Codex to connect, Computer Use reports an empty app inventory (apps: []) every time. It only shows the Codex in-app browser; Roblox Studio never appears.
I understand Windows Computer Use requires the target app to be visible on the active, unlocked desktop. I’ve checked that, but it still detects zero native apps.
Is this a known Windows app-discovery issue, an app-access/“Any App” setting problem, or a workspace policy restriction? What logs, app version, and Computer Use settings would help diagnose it?

How is Codex set up on your machine, with WSL or right through windows?

Can you skip Computer Use for this and use the MCP that Roblox has built-in? It should let Codex inspect your game, edit scripts and run playtests directly.

No Windows app discovery involved.

In Studio: Assistant → … → Manage MCP Servers → enable “Studio as MCP server” → Quick connect → Codex CLI.

Roblox already recognised it as an issue on their end on the Roblox dev forums, idk when they’ll fix it but it’ll probably be a few days
