## **Description:** **Issue:** The Browser MCP seems to be broken. The browser icon is missing from the bottom right of the Agent/Chat interface (I recall seeing it before, but never used it). Despite multiple attempts, I cannot get the Agent to control the browser. **Steps I’ve taken:** 1. Reinstalled Cursor. 2. Restarted the system. 3. Tried toggling MCP settings. **Technical Observations:** - The **“Cursor IDE Browser Automation”** only stops showing errors if I manually open a **Browser Tab** _before_ executing **“Reload Window”**. However, even when the error disappears, the Agent still cannot interact with or “see” the browser. - I have spent over 2 hours troubleshooting this with no success. **Questions:** How can I properly enable the Browser MCP so it’s accessible and controllable by the Agent? Are there specific logs I should check to see why the icon is missing? **System Info:** - **Cursor Version:** 2.6.21 - **OS:** Windows 11 - **Terminal:** CMD ![Screenshot 2026-03-24 025349](https://us1.discourse-cdn.com/cursor1/original/3X/b/3/b35dc3aa242b7b5e62a812da415af4a30fc07350.png) ---

Hi Archie. Have you tried the solution outlined in this post [Agent can't use Browser MCP - #3 by deanrie](https://forum.cursor.com/t/agent-cant-use-browser-mcp/152200/3) ? ---

Already tried, and even rebooted the Windows. Today I tried on Ubuntu, also no luck. ![Screenshot 2026-03-24 104906](https://us1.discourse-cdn.com/cursor1/original/3X/8/d/8d7e3bd3ad6f64478d40e16b125e5589af168779.png) ---

The Browser MCP is not working on Mac Book Pro as well. V2.6.19. ---

Hey, thanks for the report and the detailed screenshots. I can see the browser-use sub-agent says tools are unavailable, even though the extension logs show a successful connection. This is a recurring issue we’ve fixed a few times, but since you’re seeing it on 2.6.21 across three different OSes (Windows, Ubuntu, Mac), it might be a new regression. Do you have any third-party browser or MCP extensions installed? Please try disabling them to rule out conflicts. I also need: - The Request ID from a failed chat: top right three-dot menu \> Copy Request ID - Any errors from the Console: Help \> Toggle Developer Tools \> Console tab, then try using the browser tool and see if any red errors show up Your report across 3 OSes is really helpful context. Let me know what you find in the console. ---

Since 3 OSes all have the issue. I think you should be able to let Agents to reproduce the issue and fix it. 2.6.22 still has the issue. ---

Can’t see the browser button here either. Tried the solution outlined above - but no dice.
