### Where does the bug appear (feature/product)? 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: 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 ### Operating System Windows 10/11 ### Current Cursor Version (Menu → About Cursor → Copy) Version: 2.3.30 (system setup) VSCode Version: 1.105.1 Commit: d1289018cc3fcc395487f65455e31651734308d0 Date: 2026-01-08T05:21:38.211Z Electron: 37.7.0 Chromium: 138.0.7204.251 Node.js: 22.20.0 V8: 13.8.258.32-electron.0 OS: Windows\_NT x64 10.0.26100 ### 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 ?

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 > **[GitHub - remorses/playwriter: MCP to control your Chrome window via extension....](https://github.com/remorses/playwriter)** > > MCP to control your Chrome window via extension.

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… ---

Update: I deleted my .cursor entries for workspace and the directory. Yes, that caused me to lose all my chats which is BS and sucks, but c’est la vie. I was then able to add the directory in cursor and save a new workspace file, which does create the necessary /tools directory. But if I enable autosave on the workspace, that tools directory gets deleted the first time autosave happens. So Cursor devs, there’s your smoking gun. ---

Thanks @Dario_Tschannen, this worked for me! ---

Adding some root cause analysis from log files that may help the Cursor team fix this. Still hitting this on **Cursor 2.4.31** on Windows 11 (multi-root `.code-workspace`). ## Root Cause (from extension logs) The `Cursor IDE Browser Automation` extension calls `injectBrowserUIScript` **once** during activation. If the Simple Browser panel is not already open at that moment, it fails and **never retries** : **Cursor IDE Browser Automation.log:** ```auto [INFO] Cursor Browser Automation extension activated [INFO] Browser Automation MCP Provider initialized with direct execution [INFO] injectBrowserUIScript called [ERROR] Failed to inject browser UI script:: No browser view available Error: No browser view available at jyt (workbench.desktop.main.js:34255:73836) ``` The MCP server then permanently reports 0 tools for the entire session: **Mcp FileSystem Writer.log:** ```auto MCP server "cursor-ide-browser" (cursor-ide-browser): 0 tool(s), 0 resource(s), 0 prompt(s) {"status":"connected"} ``` The `browser-use` subagent then fails with: ```auto Error: MCP file system options are required for CallMcpTool ``` ## Why the “Reload Window” workaround doesn’t work There’s a **race condition** : after Reload Window, the extension activates _before_ the Simple Browser panel is restored, so `injectBrowserUIScript` fails again with the same “No browser view available” error. ## Suggested Fix The extension should use an **event-driven retry** — listen for when a browser view becomes available (e.g., `onDidChangeVisibleWebviewPanels` or similar) rather than attempting injection only once at activation time. ## Environment - Cursor: 2.4.31 - OS: Windows 11 (10.0.26200) - Workspace type: Multi-root (.code-workspace file) ---
