Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The AI agent opened a browser (DuckDuckGo) via mcp_cursor-ide-browser_browser_navigate with url: “about:blank” while creating an implementation plan. The browser tool wasn’t needed for this task.

Steps to Reproduce

Ask the agent to update documentation and create a plan for code changes
Agent creates a plan using mcp_create_plan
Agent also calls mcp_cursor-ide-browser_browser_navigate unnecessarily

Expected Behavior

The agent should not open a browser when creating plans unless web research is required.

Additional Information

This isn’t a big issue, but seeing a browser window flash open and then close gives me the heebie-jeebies.

Does this stop you from using Cursor

No - Cursor works, but with this issue

To be clear, the details of how to reproduce were written by the cursor agent. I’m assuming it’s not lying to me.

Hey, thanks for the report!

I can see the issue. The agent calls the browser tool with about:blank while creating a plan, even though web search isn’t needed. That does look like overly aggressive browser tool behavior.

I’ll pass this to the dev team to investigate. The Request ID will help us understand why the agent decided to use the browser tool in this context.
