same issue here:
can't make claude code to PhpStorm IDE.
was working fine yestarday - today - no luck even after a few restarts of both CC and phpstorm.

logs:
2025-11-16T07:57:00.805Z [DEBUG] MCP server "ide": Starting connection with timeout of 30000ms
2025-11-16T07:57:01.466Z [DEBUG] MCP server "ide": Connection failed after 662ms: socket hang up
2025-11-16T07:57:01.467Z [ERROR] MCP server "ide" Connection failed: socket hang up

terminal app: iterm2 on macos.
same with internal terminal in IDE.
cc in both terminal can claim it's connected to ide! but in reality - nope.

and ide does not show the option to send files/lines to CC in a dropdown menu.

Still an issue

if you don't fix the issue - it does not usually fix itself. isn't it?..
it is still ongoing as it was for months already...

Just to provide a little bit of counter-report. My Webstorm integration been working without any issues. I also made sure I use the new jetbrains terminal (you need to explicitly enable it in settings), so this might be related.

The only perhaps tiny "issue" is that when I start claude code in external terminal, for the first 5 - 10 seconds it says IDE disconnected. But in reality they both work, or maybe it's just a startup delay.

Terminal: Reworked 2025 setting?
still does not work :(

other mcps work fine.
maybe it has something to do with proxy with is not optional for me... but this same setup was working fine initially.

Yeah reworked that's the one.
Can you try following things please also (these worked for me).

• Make sure webstorm/phpstorm is installed through Jetbrains Toolbox and is up to date from there
• Open ~/.claude/ide folder and make sure there's just one .lock file, I had problem with this when linking webstorm to claude code from twi different workspaces. Then close IDE. Open normal terminal again, launch claude and type /ide again as you might need to re-connect it
• Launch claude in normal (non IDE) terminal then wait for 2 - 5 secs, and do /ide make sure your wbestorm/phpstorm is selected and there are no warnings. /exit from claude in terminal
• Open IDE, wait a couple of seconds. Try cmd + esc or option + cmd + k, or whatever is your shortcut to launch claude from jetbrains IDE.

I do agree though that the feature set is limited compared to vscode (and it's clones). Looks like the only LSP tool that is available is getDiagnostics. Which shows warnings/errors in currently viewed file. Other LSP tools like goToDefinition etc seems to be unavailable from webstorm, although I already use them with claude code lsp plugin and local global lsp server for my language of choice, but would be nice if webstorm plugin was exposing better LSP tools

The only other features besides getDiagnostics tool from webstorm's LSP that it has that I noticed:

• cmd + options + K would send current file directly to context. What's cool it works with both standalone terminal and webstorm's TUI terminal
• cmd + esc - just a shortcut to open IDE terminal and launch claude immediatly, nothing fancy

@Yuripetusko thanks, but nothing worked :)
i have tried to reinstall native claude code cli and it connected with IDE. but fails to authenticate because i am behind corporate proxy. and native app have a bug with proxy: https://github.com/anthropics/claude-code/issues/14165
so i am stuck with depricated npm installation which fails to work with ide. :(
i reinstalled with npm to confirm - it does not connect to ide.
tried to disable proxy with NPM installation - it boom! it connects to IDE but fails to connect to APIs :))) so obviously proxy is a problem!

by the way @Yuripetusko your config is also not fully functioning probably. you suppose to see currently selected file or selected lines in IDE inside claude code and be able to send lines from the context menu - look at this screen:

<img width="1282" height="831" alt="Image" src="https://github.com/user-attachments/assets/92c6cb29-43c1-4459-9b9d-309fe146ab21" />

this is what i see and can do without proxy. but it's useless because api is not available.

proxy config in shell config:

export HTTP_PROXY=http://127.0.0.1:8888
export NO_PROXY="localhost 127.0.0.1"

i have made it work by switching from proxy to VPN. now API and IDE integration work as expected. but i think it's still a bug that claude goes through proxy while trying to connect to the IDE plugin.
but at least we have narrowed down the issue and have a workaround for people who have an option to use VPN instead of proxy.
@Yuripetusko it's not using MCP for selection passing. it is injected via system reminder. i guess it's a block attached to a conversation like this.

<system prompt>
...
</system prompt>
... previous convesation...
<system reminder>
selected code
</system reminder>
your request

Oh this is cool. So turns out it isn't working for me properly as well haha

The documentation claims claude can see open files:

Selection context: The current selection/tab in the IDE is automatically shared with Claude Code

But this is not working for me:

Even with WebStorm connected via /ide, the only IDE tool available to me is mcp__ide__getDiagnostics — which fetches errors/warnings for a file. There's no tool exposed for reading the currently open file or selected text.                                    
                                                                                                                                                                                                                                                                    
  The IDE integration in Claude Code currently supports:                                                                                                                                                                                                            
  - Diagnostics (errors/warnings) via the MCP tool                                                                                                                                                                                                                  
  - Opening files at specific lines (when I reference file_path:line_number in my responses, your IDE can navigate there)                                                                                                                                           
                                                                                                                                                                                                                                                                  
  It does not give me the ability to see your active editor tab or text selection. You'd still need to paste that content into the chat.

I'm using WebStorm 2025.3.2, Claude Code 2.1.59, and version 0.1.14-beta of the plugin.

Edit: I'm on macoS 26.3.
