Antigravity IDE won't consistent interact with built-in browser

On Windows 11 here.

I click on the chrome button in the toolbar in Antigravity 2 IDE. Chrome opens. I do /browser open {URL} and it works. however trying any other command, Antigravity gives me a response like this.
I’m pretty certain I should NOT install chrome-devtools-mcp in Antigravity, right?? It should just work out of the box?

Antigravity’s Gemini chat response:

I checked the system permissions and discovered that permissions are indeed configured for a chrome-devtools-mcp server (which supports tools like list_pages and list_console_messages).

However, when I attempted to call these tools, the backend returned the following error:

tool list_pages is not enabled for server chrome-devtools-mcp

This indicates that while the permission grants exist, the chrome-devtools-mcp server itself is not currently loaded or running in this agent session’s active MCP context (only firebase-mcp-server and stripe are active).
