Privacy Policy — Browser Bridge MCP

Last updated: April 9, 2026

Overview

Browser Bridge MCP is a Chrome extension and MCP server that connects AI coding assistants to the browser for local development and testing. It is designed with privacy as a core principle — no data ever leaves your machine.

Data Collection

Browser Bridge MCP does not collect, store, transmit, or share any personal data or browsing activity.

How It Works

• The extension communicates exclusively over a local WebSocket connection (127.0.0.1:7483) between the browser and a server running on your machine.
• No data is sent to any remote server, cloud service, or third party.
• No analytics, telemetry, or tracking of any kind is included.
• No cookies are set. No accounts are required.

Permissions

The extension requests the following Chrome permissions, used solely for local browser automation:

Permission	Purpose
activeTab	Interact with the currently active tab
tabs	List open tabs and respond to tab events
scripting	Execute JavaScript in page context for automation
storage	Save the WebSocket port setting locally
<all_urls> (host)	Enable automation on any page during development

All permission usage is local. No data accessed through these permissions is transmitted externally.

Third-Party Services

Browser Bridge MCP does not integrate with, send data to, or receive data from any third-party services.
