How to connect to mcp-jetbrains?

[zeroarst]

Jetbrains has their mcp that you can connect to any Jetbrains IDEs: https://github.com/JetBrains/mcp-jetbrains
I tried with this command:

uvx mcpo --port 8000 -- uvx npx -y @jetbrains/mcp-proxy

But it is just stuck there. I have tried mcp-server-time, it works.
Does anyone know why? T

I just tried uvx mcpo --config config.json

{
	"mcpServers": {
		"jetbrains": {
	  		"command": "npx",
	  	    "args": ["-y", "@jetbrains/mcp-proxy"]
	  	}
	}
}

But I got the error:

The erorr is : mcp.shared.exceptions.McpError: No working IDE endpoint available.
I use the same config in Claude IDE, and it works fines.

I use Windows terminal + Git bash + uv.
