  "works": "Re-checked a different way on PyPI 0.13.14, offline in a sandbox: drove the bundled MCP server over stdio with the official MCP Python SDK client (no model) and inspected DOM serialization through the BrowserSession API. tools/list returned 16 tools; navigate, get_state, type, click, get_html, go_back, new-tab navigation, list_tabs, screenshot, scroll, list_sessions and close_all all worked on local pages, an email-looking typed value was masked in the reply, and no Chrome processes were left behind.",
  "breaks": "Confirmed the original bug: page text given to the agent model drops every one-character text node (the MCP get_state tool does include them, so only the agent route is affected). New in the MCP route: browser_navigate always answers 'Navigated to <url>', even when the connection is refused or the allowlist blocks the page; the first start writes a default config with a placeholder model key, so browser_extract_content without a real key takes about 14 seconds and returns 'No content extracted' with no error flag; element-not-found and missing-argument replies are plain text, not marked as errors; get_state shows the URL as the page title and list_sessions shows no current URL; the server defaults to a visible Chrome window with a persistent profile in the home folder.",

   "Prescreen clean: not on the Agent Tested malware list and no OSV records for 0.13.14; the old allowed-domains bypass advisory was fixed long ago (0.1.45) and the restriction held in this test. Neutral notes: anonymous telemetry is on by default; page text, including any instructions planted on a page, goes to the model verbatim, so treat visited pages as untrusted; the CLI attaches to your real Chrome profile by default.",
   "Caution, described neutrally: in MCP mode the allowed-domains setting was not a reliable boundary in this check. The browser could contact a non-allowed host before the tab was reset, and a full-URL style allow entry did not always keep non-allowed pages out. Use domain-only entries and enforce network egress limits outside the browser if containment matters. No other new finding."
