OpenGuanlan Browser Bridge is a read-only browser extension for Guanlan. It
helps AI agents collect user-authorized target-page visible evidence from
Chrome or Chromium and send it to a local openguanlan daemon
running on the same computer.
The extension can read the current target page URL, title, visible text, visible links, visible frame metadata, and visible HTML structure after the user grants the current site and authorizes a Guanlan browser-assist task.
The extension does not collect or read cookies, tokens, passwords, localStorage, sessionStorage, browser profiles, browser databases, keychain data, hidden credential fields, or unrelated private pages.
Data is used only to create Guanlan browser-visible evidence for the target
page requested by the user. The extension sends results only to the local
openguanlan daemon on 127.0.0.1 or
localhost. The extension does not sell data, use data for
advertising, or send browser page content to a remote server.
The extension uses tabs, scripting,
activeTab, localhost host permissions, and optional
per-site host permissions. It does not request cookie, storage, debugger,
downloads, or native messaging permissions.
Users choose which sites to grant. Users can revoke site permissions in
Chrome's extension settings at any time. Users can stop the local bridge by
terminating the openguanlan daemon process.
