Frequently Asked Questions
Common questions about Oh My Browser, MCP, Site Memory, and how to get started.
01.What is MCP and why does it matter for AI agents?
MCP (Model Context Protocol) is an open standard that lets AI agents call external tools in a structured way. Oh My Browser implements an MCP server so agents in Claude Code, Cursor, Codex, Windsurf, and other MCP clients can control a real Chrome browser with a single tool call. No custom code, no brittle Playwright wrappers — just drop the connection config and start browsing.
02.What is Site Memory?
Site Memory is Oh My Browser's learning layer. After your agent successfully interacts with a page, the extension caches the CSS selectors and page structure it used. On the next visit to the same site, it skips the discovery step and goes straight to execution. Memory is private to your account and is deleted when you delete your account.
03.What is the difference between Lite and Oh My Browser?
Lite installs and updates through the Chrome Web Store. It supports reading and acting on logged-in pages and generic page diagnostics. The current Lite package omits some deep browser capabilities included in the unpacked full edition; that is a product packaging choice, not a blanket Web Store prohibition. Both editions need OMB CLI/Agent connection.
04.Does Oh My Browser share my browsing data with the AI agent?
No. The extension does not stream your browsing history or session tokens to the agent. The agent sends a task (e.g., 'read this URL') and receives only the result of that task. Your cookies and credentials stay in Chrome. The extension does cache anonymized site-structure signals (selectors, page layout) to power Site Memory — these are private to your account and never shared across users.
05.How do I connect Codex or Claude Code?
Run the single command on the Install page. The script detects installed clients and configures OMB automatically. Follow its instructions to load the browser extension and sign in. If OMB is already installed, run `"$HOME/.omb/omb" integrate --auto` to detect and connect your clients again.
