In the realm of browser automation, existing tools like Playwright or DevTools MCP often require launching separate browser instances or relying on debugging ports, making it difficult to directly control real Chrome profiles that are already logged in with extensions and history. This creates pain points for AI agents trying to seamlessly access users' actual sessions, leading to cumbersome profile copying, high security risks, and challenges in managing multiple profiles. Chrome Faithful addresses this issue through a combination of a local authenticated bridge, MV3 extension, and MCP server, enabling faithful control over real Chrome profiles.

Its core capabilities include precise multi-profile routing: each profile registers with an exact name to avoid conflicts; and robust security design where the bridge binds only to localhost and requires a generated 256-bit secret, with all operations within a closed architecture that avoids external debugging tools. Additionally, the plugin supports file injection, media streaming exports, persistent scroll capture, and intelligent verification handling, while ensuring sensitive information like cookies and tokens never leaks into MCP arguments. For AI agents, it also offers a Codex-compatible JS API and local vision extraction, facilitating integration into existing workflows.

Chrome Faithful is ideal for AI agent developers, automation test engineers, and security-conscious administrators who need to control real browser sessions. Whether managing multiple accounts, interacting with complex web applications, or performing tasks that require persistent login states, it provides a reliable solution. Its integration with DeepSeek Harness further enhances its usability within agent ecosystems, making it a preferred tool for handling high-trust browser operations.
