How to use the --save-trace generated file?

[eret9616]

{
  "mcpServers": {
    "playwright": {
      "transport": "stdio",
      "enabled": true,
      "command": "npx",
      "args": [
        "@playwright/mcp@latest",
        "--output-dir=/Users/hh/Desktop/output",
        "--save-trace",
        "--headless"
      ],
      "env": {},
      "url": null,
      "headers": null
    }
  }
}

I let the mcp server run some task,i can see it generate a folder named trace and some files here, but I dont know hot to use this trace file ,

https://playwright.dev/docs/trace-viewer-intro
document say there should be a trace.zip file , i tried to compress these folder , but still cant use
in https://trace.playwright.dev/

This feature is still very rough around the edges. There's a local trace viewer server running:

❯ npx @playwright/mcp@latest --save-trace

Trace viewer listening on http://localhost:60096/trace/index.html?trace=/var/folders/g0/6cfmrv7j7ls58c3f9gp04qfh0000gn/T/playwright-mcp-output/2025-06-26T16-33-35.682Z/traces/trace.json

You can get the URL from stderr, if your MCP client shows that, or from your terminal if you use the http transport.
