Can't turn off new Browser feature

Bug Reports
1

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

We have classic Privacy turned on and the browser feature is not available.
We use a custom MCP to connect to chrome that can only access localhost.
When ever I mention browser in the AI chat, it enables the ■■■■ internal browser module and hides my chrome MCP.
How do I permanently disable the new IDE browser feature since I’m using my own MCP

Steps to Reproduce

To demonstrate, install chrome-devtools MCP.
Enable privacty mode (Legacy) (disable browser extension)
Then ask the AI to access google.com.
It will find the browser tools, but all of them will fail.
If you click on the browser icon in teh chat and disable the browser extension, then it finds the chrome extension and uses it correctly.

Expected Behavior

If I turn OFF the browser extension using the browser icon it shoud STAY OFF.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. It looks like a bug with tool preference persistence. The browser tool shouldn’t turn back on after you disable it, especially when you’re using a custom MCP server.

I’ll pass this to the team for investigation.

Let me know if the behavior changes or if you notice any patterns around when the browser tool re-enables.
