Description

What's going on?

I am adding playwright MCP and want it run on Edge (by default it takes Chrome). The mcp fails to load saying browser is not recognized argument. Let me know if I'm missing anything!

Failed to connect to MCP server "playwrite": error: unknown option '--browser'. Execute '/mcp show playwrite' to inspect or check the logs.

"playwrite": {
      "tools": [
        "*"
      ],
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@playwright/mcp@latest",
        "--browser",
        "msedge"
      ]
    }
