Browser FAQs

Question 1

What is MCP Browser?

Accepted Answer

MCP Browser is a native macOS web browser designed to be controlled by AI agents via the Model Context Protocol (MCP). It enables agents to navigate, interact with web elements, extract content, and manage local browsing sessions within a real WKWebView instance.

Question 2

How does MCP Browser ensure data privacy and security?

Accepted Answer

It operates locally on your machine with no telemetry or cloud sync. Connections require a per-launch bearer token, and DNS-rebinding defense is built-in. All agent actions are recorded in a transparent log, and user confirmation is required for sensitive actions like downloads or uploads.

Question 3

Can AI agents use my existing logged-in browser sessions?

Accepted Answer

Yes, a core benefit of MCP Browser is that it runs on your Mac, allowing AI agents to access your local browsing environment, including cookies, history, and logged-in sessions, just as you would use it yourself.

Question 4

What are the advantages of MCP Browser over headless or remote cloud browsers?

Accepted Answer

MCP Browser provides a visible, native macOS browser experience on your machine, sharing your local sessions and keeping all data local. This avoids the limitations of headless browsers (different engine, no shared sessions) and the data privacy/cost concerns of remote cloud solutions.

Question 5

What is the Model Context Protocol (MCP)?

Accepted Answer

MCP (Model Context Protocol) is a standardized way for AI agents and Large Language Models (LLMs) to communicate with and control external tools and services, such as a web browser, enabling them to perform complex tasks in a structured manner.
