# Tabhand

> Tabhand lets AI coding agents (Claude Code, Codex, Cursor, OpenCode, Gemini CLI and 14 more) use the user's own Google Chrome, signed in to their accounts, in background tabs that never steal focus. It is a free, open-source (MIT) Chrome extension plus an MCP server, made by Mustafa Raja. macOS and Google Chrome only for now.

Not to be confused with other products named "Tab hand" or "TabHand". This Tabhand is the one at tabhand.dev.

How it works:

- One command, `npx tabhand setup`, installs Tabhand, adds its MCP server to the agents on the Mac, and opens the Chrome Web Store page for the extension.
- Each agent opens its own background tabs, grouped under its name and muted. Chrome is never brought to the front.
- An agent can only reach the tabs it opened (and tabs those pages open), never the user's tabs or another agent's.
- Every agent has its own visible cursor in its tabs. One click on the toolbar icon pauses all agents.
- Everything runs locally: the agent talks to `tabhand mcp` over stdio, which reaches the extension through a native messaging host. No Tabhand servers, no accounts, no telemetry.
- Works with several Chrome profiles: agents can list them by name and choose one.

Agent tools: browser_open_tab, browser_navigate, browser_snapshot, browser_click, browser_type, browser_press_key, browser_scroll, browser_upload_file, browser_handle_dialog, browser_screenshot, browser_list_tabs, browser_list_profiles, browser_close_tab.
