Hey, thanks for the report.
This is a known issue, a regression in versions 2.3.18+. The team is working on a fix. Browser automation should work through the built-in tools and it does NOT show up as a separate MCP server in Settings > MCP.
To help us fix this faster, can you share:
- Help > Toggle Developer Tools > Console: any errors when you try to use the browser tools
- The Request ID of the failed call (chat context menu > Copy Request ID)
- What do you see in Settings > Tools & MCP > Browser Automation?
