[BUG] Claude Code doesn't detect that the IDE is cursor

Thanks for the report! What does /status say about IDE?

try cursor --install-extension ~/.npm-global/lib/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix

I got the same error after I restarted cursor.

@DashBarkHuss Did you try the direct install with cursor from the CLI? If you have Claude code working you can just install the extension from the npm directory manually. Just double check your npm location for your machine. Or better yet, just feed this info to Claude code and have him do it for you

once I found the correct directory the direct installation worked and now claude code recognizes cursor.

It won't let me reopen the issue, but the status command shows that there's still an error with the installing the cursor extension. Restarting the IDE didn't fix it.

I get the error too so I wrote a gist how to solve it manually just in case based on this issue.

Apparently this doesn't work in linux?

I ran cursor --install-extension ~/.claude/local/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix and nothing happens, and also if I press ctrl+shift+p and select Developer: Install Extension From Location... and navigate to ~/.claude/local/node_modules/@anthropic-ai/claude-code/vendor/ cursor doesn't see the claude-code.vsix. If I run /ide command Claude says "No available IDEs detected. Make sure your IDE has the Claude Code extension or plugin installed and is running.".

I'm running:
Kubuntu
6.13.9-x64v3-xanmod1
Claude Code v1.0.3
Cursor 0.50.7

I encountered the same issue where Cursor IDE wasn’t recognized by Claude Code, despite successful installation attempts via CLI. None of the provided solutions fully resolved my issue. However, I discovered a straightforward workaround that resolved it:

1. Manually located the Claude Code extension .vsix file within my local Claude installation directory.
2. Dragged this .vsix file directly into the Cursor Extensions panel.

The extension installed successfully and immediately became operational within Cursor.

This approach bypassed the issues I encountered with automatic detection and CLI-based installation methods.

I hope this helps others experiencing similar issues!

@Xupack88 It defiantly works in linux. To effectively troubleshoot this you need to take into account where and how node is installed and what OS you are on. So to better address this to a broader audience you can do the following if npm is installed globally:

1. npm list -g --depth 0 (reference: where does npm install the packages )
2. Manually install the claude-code.vsix via the file path for where you have Claude Code installed. If you look at the npm repo you will see it is located at: @anthropic-ai/claude-code/vendor/claude-code.vsix (referance: npm claude code )

• @sotayamashita created a gist (see above) with a great way to find where claude code is installed on your specific machine using claude code itself.

Updated to 1.0.7, but still my claude code fails to detect the cursor IDE inside devcontainer (though it worked on local).

Here's my workaround;

{
  "features": {
    // Install claude-code
    "ghcr.io/anthropics/devcontainer-features/claude-code:1": {}
  },
  "customizations": {
    "vscode": {
      "extensions": [
        "/usr/lib/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix",  // <- Set path to claude-code.vsix
      ]
    }
  },
}

Hope this helps someone.

Had the same problem, I went in the extension tab installed npm intellissens clicked on the claude code > went back to the terminal > claude > and I had a status. Finally after 3 hours lol

Thank you very much! It worked but /status still shows this:

I had the same problem, this also worked for me!

I tried doing what most of you have done. I am on Fedora 42 here are my system info:
Cursor Version: 1.0.0
VSCode Version: 1.96.2
Commit: 53b99ce608cba35127ae3a050c1738a959750860

OS: Linux x64 6.14.9-300.fc42.x86_64

my claude-code is at /usr/local/lib/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix

I ran this in the terminal of an open Cursor session: cursor --install-extension /usr/local/lib/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix

When I run it a new Cursor window opens, and I still don't see the IDE connect and it says No available IDEs

Any suggestions are appreciated!

For me it worked by installing the vsix file manually, before that I got the following:

Error installing Cursor extension: 1: 1 [225580:0602/225531.492518:ERROR:ozone_platform_x11.cc(246)] Missing X server or $DISPLAY [225580:0602/225531.492547:ERROR:env.cc(257)] The platform failed to initialize. Exiting. Please restart your IDE and try again.

This is the final method that works.

• first step: install Claude code
• run: npm list -g @anthropic-ai/claude-code
• Copy the Claude code extension to a folder u can easily access
• cp /use your path/.nvm/versions/node/v22.12.0/lib/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix ~/Downloads/
• Open cursor and Ctrl+Shift+p,
• Type: Extension install from VSIX
• Locate the claude-code.vsix select it, and after installation, close and reopen cursor: open your terminal and enjoy using claude

This is the final method that works. first step: install Claude code run: npm list -g @anthropic-ai/claude-code Copy the Claude code extension to a folder u can easily access cp /use your path/.nvm/versions/node/v22.12.0/lib/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix ~/Downloads/ Open cursor and Ctrl+Shift+p, type: Install extension from location Locate the claude-code.vsix select it and after installation close and reopen cursor: open your terminal and enjoy using claude

Your steps didn't directly help me but I ended up figuring it out, there is a 'VSIX' specific install in vscode/cursor here is what I ended up do, I hope this helps someone else!

1. Install Claude code
2. run: npm list -g @anthropic-ai/claude-code
3. cp /usr/local/lib/node_modules/@anthropic-ai/claude-code/vendor ~/Downloads/
4. Open Cursor
5. Press Ctrl+Shift+P to open command palette
6. Type "Extensions: Install from VSIX..." (not "Developer: Install extension from location...")
7. Navigate to /home/username/Downloads/claude-code.vsix
8. Select the file and click "Install"
9. Restart Cursor

The key is using "Extensions: Install from VSIX..." instead of "Developer: Install extension from location...".

It's the same thing. U got it

YES! This worked also in Arch Linux - this post should be more upvoted! :D
Thanks alot for this

I didn't see the vsix file in my downloads folder or anywhere else, so I prompted in code "i need to download the local vsix claude code file to connect claude code with cursor - going to the extensions marketplace is not a solution as there are too many fake extensions" and it downloaded to my downloads folder. After that I just dragged the file into extensions and it showed up in /ide!

This is what I did and it worked:

Step 1: Run the below command
cursor --install-extension \
~/.claude/local/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix

Step 2:
In Cursor press ⌘ ⇧ P → “Shell Command: Install ‘cursor’ command in PATH”, then reopen your terminal and try again. Claude’s auto-installer only works when the cursor binary is discoverable.

I ran into the same issue when using Cursor with a Dev Container, and after some trial and error, I was able to resolve it. My solution is similar to the general flow others have described, but here’s what specifically worked for me:

1. Run the following to check where claude-code is installed:

npm list -g claude-code

1. Then install the extension manually using the following command (replace the path with the actual one from step 1

cursor --install-extension <your-path>/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix

Same issue for me, it seems Claude Code updated and in some moment integration with cursor disappeared. It also dont work in vscode and vscode insider preview. I tried to install extension in insider preview with all mentioned above options. Every time extension installed, and it started on some port. Also it successfully creates lock file in ~/.claude/ide folder.
In Claude Code /status shows me ✔️ Installed VS Code extension.

So it seems extension working fine, I dont see any issue with it. But command /ide shows me No available IDEs detected. Make sure your IDE has the Claude Code extension or plugin installed and is running. And I dont know how to debug this problem more detailed. Claude code version 1.0.31

UPD. I found problem: In new versions Claude Code extension creates lock files into ~/.claude/ide but claude code itself tries to find lock files in ~/.config/claude/ide. Symlinks can resolve this issue.

THANK YOU. Worked for me on Arch getting external terminal to recognize ide (the extension inside ide working properly required VSCODE_IPC_HOOK_CLI=/tmp/vscode-ipc-$(whoami).sock to be passed at launch - so many workarounds :X

For me the problem was on Windows, so I just started Cursor from the wsl terminal using cursor . and then all works fine, installing the pluggin and running the integration so Claude gets the context too

I'm on windows 11 using WSL Ubuntu. I already had Cursor installed on windows and then I installed Claude Code into Linux via WSL. I am trying to get Cursor and Claude Code to work together.

Should I install Cursor into my Linux environment?

Found this guide that was a huge help for me. If your running Cursor on Windows and Claude in WSL this can help sort it all out.

It won't let me reopen the issue, but the status command shows that there's still an error with the installing the cursor extension. Restarting the IDE didn't fix it.

Hi @DashBarkHuss , I have the same error too. Have you found the solution?

Same issue here. Running Cursor on Mac, all was working but now the actual problem is that Claude Code does not seem to understand that starting from the folder which Cursor is running is the same - even it is and cwd at Claude start is EXACTLY the same as the error message: Found other IDE running where project/workspace folder does not match the current one (then tells the same folder)

clicking this little orange Claude button (which starts claude in a terminal) on the top right of the editor window fixed the issue for me. Now it connects to the IDE properly. I only noticed it today... must be new.

Why has it been closed? It's still an active issue for me.

Why has it been closed? It's still an active issue for me.

If you are using Windodows you must use WSL and in the IDE use the remote Windows to WSL in order to let Cloude Code recognize the IDE.
If you are using macOS/Linux that is actually the same issue and you should add more info in order to reopen this.

This is still an issue. The small icon has disappeared from the IDE
