Overview

AlienMcp is a browser automation Chrome extension that connects AI agents to your browser via the Model Context Protocol (MCP).

Data Collection

AlienMcp does not collect, transmit, or store any personal data.

All communication happens locally between the Chrome extension and a local MCP server on your machine (localhost:7888). No data is sent to external servers.

What the Extension Accesses

When you explicitly use AlienMcp tools, the extension may access:

• Tab information (URLs, titles) - for tool commands and popup display
• Page content (DOM, text) - when using read, find, or modify tools
• Screenshots - when using the screenshot tool
• Cookies and storage - when using cookies or storage tools
• Network requests - when network monitoring is enabled
• Console messages - when console capture is enabled

All data stays on your machine and is only accessible to the MCP client you use locally.
