Browserstack integration with Cline in Windows is not working

[uthircloudnative]

Hi,

I am trying use Browserstack MCP server with Cline in my windows machine getting below error.

node:events:502 throw er; // Unhandled 'error' event ^ Error: EPERM: operation not permitted, open
'C:\Program Files\Microsoft VS Code\NUL' Emitted 'error' event on ThreadStream instance at: at Immediate.<anonymous>
(C:<My project path>\index.js:369:12) at process.processImmediate (node:internal/timers:491:21) Node.js v22.13.1 MCP error -32000: Connection closed

My System configuration

Window 11 Enterprise
Node v22.13.1
VS Code 1.98.2

My Cline MCP server configuration.

"browserstack-mcp-server": {
  "disabled": false,
  "timeout": 180,
  "command": "node",
  "args": [
    "C:\\<path>\\mcp-server-main\\dist\\index.js"
  ],
"env": {
        "BROWSERSTACK_USERNAME": "<userName>",
        "BROWSERSTACK_ACCESS_KEY": "<AccessKey>"
      },
  "transportType": "stdio"
}

In this case I downloaded the MCP server code to my local and started the mcp server with

node dist/index.js

When I execute above command code is getting started without any issue. But when I connect this server in Cline getting above error.

Not sure its some permission issue. I have tried to run my VS code in administrator mode but still got the above error.

Got the same error with below config as well

"browserstack-mcp-server": {
  "disabled": false,
  "timeout": 180,
  "command": "npx",
  "args": [
        "/c",
        "npx",
        "-y",
        "@browserstack/mcp-server@1.1.5"
      ],
"env": {
        "BROWSERSTACK_USERNAME": "<userName>",
        "BROWSERSTACK_ACCESS_KEY": "<AccessKey>"
      },
  "transportType": "stdio"
}

Can you try running this npx @browserstack/mcp-server@latest in powershell ?
Expected output is actually nothing, the server will start but won't print anything to the console.

I can able to run the application with command line interface with below command.
npx -y @browserstack/mcp-server@1.1.5 --BROWSERSTACK_ACCESS_KEY= --BROWSERSTACK_USERNAME=

Once the application is starts I need to configure this MCP server with Cline and Cline tool should be able to integrate with running MCP server. When Cline is try to connect this MCP I am getting above mentioned issue.

Looks like from Cline when try to connect the running MCP (bowserStackServer) its trying to make some changes in my VS Code folder file that's where I am getting Operation Not permitted issue.
