Integration with Rider does not seem to work

[ArkTarusov]

This is an error from Rider AI. I added line breaks because the error is output on one line.

Rider AI can copy MCP servers from Claude.
I used this feature. Manually adding a server results in the same results.
I have several other MCP servers, they work well.

Hi, thanks for getting in touch. I'm not sure what's the context. Could you explain the steps to reproduce this issue?

[ArkTarusov]

Hi!
Sure - here are the steps to reproduce the issue:

• Use the "Copy from Claude" function to import MCP server configs, or add the MCP server manually.
• Save the settings.
• Make sure that the commands from mcp-dockmaster are not available for JetBrains AI.
• Return to the JetBrains AI MCP settings - in the list of MCP servers, you should see an error next to mcp-dockmaster.

"mcp-dockmaster": { "args": [], "command": "\\\\?\\C:\\Users\\Arkta\\AppData\\Local\\MCP Dockmaster\\mcp-proxy-server.exe" }

Connecting mcp-dockmaster to Claude is done without problems.

Hi @ArkTarusov I was able to reproduce it. I'm just finishing a huge refactor to have the app up to date in terms of mcp and then I can take a look on this issue to make it works.

Heeey @ArkTarusov I found the issues affecting IntelliJ products (I was testing with RustRover) and it should be fixed on the next release v1.0.9.

Basically, IntelliJ products flag an mcp server as errored if it finds anything in the stderr channel (apps like Claude and Cursor works different).

Here is the PR #170
