Claude Code IDE Connection Issue

Environment

  • Platform (select one):
  • [x] Anthropic API
  • [ ] AWS Bedrock
  • [ ] Google Vertex AI
  • [ ] Other: <!-- specify -->
  • Claude CLI version: 1.0.4
  • Operating System: WSL2 Ubuntu (Linux Legion 5.15.167.4-microsoft-standard-WSL2)
  • Terminal: zsh in WSL2

Bug Description

Claude Code CLI fails to detect IDE connections despite extensions being properly installed and accessible through Command Palette. The CLI consistently shows "No available IDEs detected" even when IDEs are running with Claude Code extensions installed and functional.

Steps to Reproduce

  1. Install Claude Code extension in IDE (tested with Cursor and Windsurf)
  2. Open project in WSL2 environment
  3. Verify extension is installed and Claude Code commands appear in Command Palette (Ctrl+Shift+P)
  4. Run claude command in WSL terminal from project directory
  5. Observe "No available IDEs detected" message in Claude interface
  6. Try running Claude Code commands from IDE Command Palette
  7. Check Claude terminal - no connection established

Expected Behavior

  • Claude Code CLI should detect running IDEs with Claude Code extension installed
  • IDE should appear in "Select IDE" menu in Claude terminal interface
  • Connection should be established allowing integrated development features

Actual Behavior

  • Claude Code CLI shows "No available IDEs detected" despite extensions being properly installed
  • Claude Code commands are visible and accessible in IDE Command Palette
  • No connection is ever established between CLI and IDE extension
  • Lock files in ~/.claude/ide/ show connection attempts but CLI doesn't recognize them

Additional Context

Lock File Evidence (before clearing):

{"pid":5467,"workspaceFolders":["/home/anrokx/Codebase"],"ideName":"Cursor","transport":"ws"}
{"pid":3078,"workspaceFolders":["/home/anrokx/Codebase"],"ideName":"Windsurf","transport":"ws"}

Troubleshooting Attempted:

  • Verified extensions installed and enabled in both Cursor and Windsurf
  • Cleared IDE lock files (~/.claude/ide/*.lock)
  • Killed and restarted all Claude processes
  • Restarted IDEs and WSL connections
  • Tested with single IDE to avoid conflicts
  • Confirmed IDE processes running with extension hosts
  • Tried initiating connection from both CLI and IDE sides

IDE Process Verification:

  • Cursor: cursor-server processes active with extension host
  • Windsurf: windsurf-server processes active with extension host
  • Multiple forwarded ports (15045, 30271, etc.) showing IDE services running

Command Palette Confirmation:
Claude Code commands visible and accessible:

  • "Claude Code: Insert At-Mentioned" (Ctrl+Alt+K)
  • "Fix with Claude Code"
  • Other Claude Code integration commands

The connection mechanism appears to work partially (lock files created with correct data), but the CLI fails to detect or communicate with the IDE extensions in WSL2 environment.

I was just about to create an issue.
I'm in the same situation.
In my case, after I ran /ide and selected something like "none" under "cursor", I was unable to select "cursor" again.
The none option is fine, but I wish it was possible to select it again after selecting it.

The extension itself is installed.

I'm not good at English, so I'm using a translation site to write this.
Thank you.

  No available IDEs detected. Make sure your IDE has the Claude Code extension or plugin installed and is running.

IDE integration working properly now

Izverg1 · 1 year ago

i've been getting 'IDE disconnected' today , latest VSCode, on Windows 11, WSL Ubuntu , ARM64 .

elle-empower · 1 year ago

Also getting this for VSCode today on MacOS 14.7.4, M1 Pro chip

AustEcon · 1 year ago

Still getting the issue with latest claude code where it doesn't list the Rider IDE or gets disconnected. I have seen it work previously and it shows the diffs in the IDE but for some reason I haven't been able to get it to connect for the past week.

  • Windows 11, WSL Ubuntu , ARM64
AustEcon · 1 year ago

I figured out that if I use an external terminal (non-Rider integrated terminal) I can get it to work but I still need to close Rider and re-open it after entering a claude code session.

So it seems like there is some necessary event happening when Rider IDE initially loads the project to allow claude code to reach it... But claude code needs to be already in an active session to capture this event.

ofaws · 11 months ago

happens to me after the latest Claude Code update in VS Code 1.102.3

Seems to be constantly disconnecting if I have another VS Code window opened (with other project), even if that other window DOES NOT use Claude Code

Thanks for the reports, we're investigating immediately!

WSL VSCODE IDE disconnect

I had another vscode window open for awhile (not running claude code) then I started noticing the IDE disconnect. I closed the second window and restarted my machine several times and still can't keep claude code connected to the IDE in a single window any longer, even after running /ide. Currently trying to reinstall claude code to see if that fixes things.

Had this issue on my windows/wsl, vscode after updating, it still works fine on my mac where I didn't update the claude yesterday.

hackyon-anthropic collaborator · 11 months ago

This is likely a new issue with recent updates. We're investigating right now, but please comment/provide any additional information on this issue instead:
