XcodeBuildMCP fails to connect

XcodeBuildMCP won't connect through Command Code. It works fine in other MCP clients.

Config:

"mcpServers": {
    "XcodeBuildMCP": {
      "transport": "stdio",
      "enabled": true,
      "command": "npx",
      "args": ["-y", "xcodebuildmcp@latest", "mcp"]
    }
}

What happens:
The tool shows up but calls fail silently, no error in the UI, no output, no connection. Looks like a stdio transport issue specific to how Command Code spawns MCP servers.
