I’m experiencing an issue where the @Browser MCP tools are not accessible to the AI assistant in Cursor. According to the MCP instructions, I should have access to browser tools from cursor-browser-extension and cursor-ide-browser servers, but these tools are not appearing in the available tools list.
When the assistant attempts to use browser functionality:
list_mcp_resources() returns empty: When querying for browser MCP resources, the tool returns “No MCP resources found” for both cursor-browser-extension and cursor-ide-browser servers.
No browser tools in available tools: The assistant’s available tools list does not include any browser-related tools (no browser_navigate, browser_open, browser_click, etc.).
Cannot perform browser operations: The assistant cannot navigate to URLs or interact with web pages through MCP, even when explicitly requested
Expected MCP Servers:
cursor-browser-extension
cursor-ide-browser
I precise I’ve al verified that I already activate the browser automation, and “show localhost links in browser”,i tested to explicitly call @browser but same problem
Steps to Reproduce
Request the assistant to open a URL using the browser (e.g., “use the browser tab to open google”)
The assistant attempts to use list_mcp_resources for browser servers
Result: “No MCP resources found”
The assistant cannot access any browser tools
What I’ve Tried
Called list_mcp_resources() without server filter - no resources found
Called list_mcp_resources(server="cursor-browser-extension") - no resources found
Called list_mcp_resources(server="cursor-ide-browser") - no resources found
Searched the codebase for MCP configuration - no relevant configuration found
also tried with differents models, switch agent to chat, plan etc etc.
Expected Behavior
just browser functionnality work
Operating System
Windows 10/11
Current Cursor Version (Menu → About Cursor → Copy)
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?
I’m absolutely furious! How can a critical feature like MCP have such a rookie bug? It’s like your team has no clue what testing is. This bug has been lingering since multiple versions ago and is still there in **2.3.41 (2026-01-16)**—unbelievable! You’d rather roll out new features than roll back this broken garbage? I just don’t get it!
VS Code once pushed an update that raised the libc version requirement, breaking the app for tons of old users. They fixed it the very next day, even though it was such a low-level dependency issue. But Cursor? You keep overhauling the UI and forcing your ugly agent layout down our throats, messing up our habits over and over again, while this MCP bug—where `list_mcp_resources()` returns nothing—remains unaddressed. Pathetic!
Yes it was working with an mcp server to access SQL now nada, I also filed a bug report. I have not found a way to go back to the update from a day or two ago. Is there a way.
This was working before the 2.3.41 update in the last few days (at least for the sql mcp servers).
I recommend using Playwriter.dev MCP which is far better than the Browser (unless you really want the browser window and editing tools in the Cursor IDE).
Apparently it has a significantly reduced context window - you can read all about if if you really want
It attaches to an existing tab rather than a new browser incognito window so no faff if your app uses SSO
