What can you do with familiar mcp?

familiar

Control your real macOS Chrome via AppleScript โ€” no DevTools Protocol, no Playwright.

A Claude Code skill that drives Google Chrome on macOS through AppleScript (Apple Events). It uses your everyday browser instead of a headless/automated one, so pages behind bot/WAF defenses tend to treat it as a normal user.

What it does

Everything is tab-scoped (windowId + tabId); it never relies on the "active tab".

  • list_tabs / new_tab / new_incognito_tab / close_tab โ€” tab management (new_tab uses a normal window, new_incognito_tab an incognito one)
  • active_tab / window_mode / is_loading โ€” inspect active tab / window mode / tab loading state
  • navigate / get_tab_url โ€” navigation
  • reload / go_back / go_forward / stop โ€” history & reload control
  • wait_for_load / wait_for_selector / wait_for_function โ€” wait for page load / element / a JS condition
  • get_html โ€” get the current DOM as HTML
  • get_text / get_attribute / get_value / exists / query_all โ€” read element text / attribute / value / presence / all matches
  • click / fill / clear / select_option / set_checked / press_key / submit / scroll_into_view โ€” interact with elements and forms
  • execute_js / execute_js_file โ€” run arbitrary JavaScript (use the file form for complex scripts)

Selectors accept CSS (default), text=, xpath=, and label= forms.

Prerequisites

  • macOS with Google Chrome
  • Enable Chrome's "Allow JavaScript from Apple Events" (View โ†’ Developer โ†’ Allow JavaScript from Apple Events)
  • Approve the Automation permission prompt on first run
