Unable to read the Google Sheet Web Page

[maxsxu]

Description of the bug

  The Chrome DevTools evaluation showed: JavaScript isn't enabled in your browser, so this file can't be opened. This typically happens when Chrome is loading a restricted
  Google properties page (like Google Sheets, Google Docs) and the DevTools Protocol is being blocked from executing scripts on it.

  Google actively restricts automated tools and DevTools extensions from running arbitrary JavaScript on their sensitive domains (accounts.google.com, docs.google.com,
  chrome.google.com) for security reasons.

  Let's try another approach. Instead of injecting JavaScript to pull text out, I will take a full accessibility tree snapshot of the page and parse it locally. The snapshot
  tool uses native Chrome APIs that bypass these JS restrictions.

Reproduction

1. Open a google sheet web page https://docs.google.com/spreadsheets/d/xxxx
2. Ask "summary the web page https://docs.google.com/spreadsheets/d/xxxx" in the Gemini CLI

Expectation

There should have no restrictions when the mcp-tools read the web page I've opened.
