So,
I recently tried installing Roblox studio for game development for Roblox. And i got to know it has mcp server with that i can connect my antigravity ide with roblox studio and can work with ease, when i added roblox studio server in antigravity and the connect is done i can see it on roblox studio but when i use gemini 3.1 pro high it fails to answer my queries and this is the error.
