    "incantation": "When using v0.23.0 and navigation destinations must be restricted, start the server with `--experimentalNavigationAllowlist`, then configure its URLPatterns list; if navigation is declined, update the list and retry.",
    "examples": [
      "npx -y chrome-devtools-mcp@0.23.0 --experimentalNavigationAllowlist",
      "navigate_page({\"pageId\":1,\"type\":\"url\",\"url\":\"<approved-url>\"})"

      "Version: 0.23.0",
      "Availability: Experimental; off by default.",
      "--experimentalNavigationAllowlist: Enables the experimental navigate allowlist; off by default.",
      "URLPatterns (required): List of URL patterns used to decide which navigation destinations are allowed. Pattern syntax and configuration mechanism were not found in the v0.23.0 documentation/source inspected.",
      "pageId (required): ID of the page to navigate.",
      "type: Navigation mode; `url` navigates to a URL.",
      "url: Target URL; used only when `type` is `url`.",
      "The allowlist declines navigations that land on disallowed URLs.",
      "It does not restrict subresources or JavaScript/iframe navigations.",
      "The allowlist can be updated and the navigation retried after a decline."
