I am trying to use MCP server on Windows
Any MCP opens new empty shell window
10 mcp server will open 10 new windows
Closing this window cause error “Client Closed”

Same config in Cline or RooCode works fine

Do we have some option to fix that?

Config:

{
    "mcpServers": {
        "github.com/AgentDeskAI/browser-tools-mcp": {
            "command": "cmd",
            "args": [
                "/c",
                "npx -y @agentdeskai/browser-tools-mcp"
            ],
            "env": {},
            "disabled": false
        }
    }
}

@deanrie Could you take a look when you have time?
I saw a lot of simular topic but without any solution.

Do we already have some solution for this issue?
MCP becames an important part of workflow
As option we could use approach from open source vscode tools like Cline or RooCode

Hey, I’ve already forwarded this to our team.

Yes, this issue is very annoying. It also causes Cursor to crash and close automatically when opening existing projects. I often have to try opening a project multiple times before it finally works.
