Browser MCP Tools Not Available

Cursor IDE

Describe the Bug

Hi

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:

1. 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.

2. 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.).

3. Cannot perform browser operations: The assistant cannot navigate to URLs or interact with web pages through MCP, even when explicitly requested

4. 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

1. Request the assistant to open a URL using the browser (e.g., “use the browser tab to open google”)
2. The assistant attempts to use list_mcp_resources for browser servers
3. Result: “No MCP resources found”
4. 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

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

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?

Oh, so maybe how can i regrete my cursor version to a functional version ?

Request ID : “6acbc610-7639-4496-bfaf-d185facd4b95”

Yes i see Browser automation and it is activated.

Any ETA on a fix for this?

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).

[Nobody_Here]

Same problem. I regret that I have updated. Any workaround?

What are you guys doing!!! Cursor is now unusable for me and my ultra subscribtion just renewed otherwise i would have cancled beforehand!!!

[Peter_Cox]

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

GitHub - remorses/playwriter: MCP to control your Chrome window via extension....

{

“mcpServers”: {

“playwriter”: {

“command”: “npx”,

“args”: [

“playwriter@latest”

],

“env”: {

“PLAYWRITER_AUTO_ENABLE”: “1”

}

}

}

}

Had the same issue with Cursor 2.3.41

Just downgraded Cursor to 2.2.44 and it works again like before.

[igk (Ingu Kang)]

for historical versions, there’s one repo in github.

cursor-version-archive.json

[igk (Ingu Kang)]

and to disable auto update, search update.mode in user settings (VSCode settings)

Tried to fix xcodebuildmcp somehow for 3 hours. Downgrading to Cursor 2.2 helped. Agent mode just doesn’t see any mcp tools. Only mcp resources…
