You need dedicated capabilities in the Browser Automation domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
You have access to required keys: MANZANASD_ADDR.
Primary tools included: TTL-bounded exclusive leases with FIFO queue, Warm pool of SIGSTOPped simulators for fast lease activation, UI actions: tap, type, scroll by accessibility label.
Drive iOS simulators from Claude Code, Cursor or Codex by accessibility label instead of screenshot-and-tap-coordinates. Exposes ui_tree, tap_element, type_into_element, wait_for_element and scroll_to_element, and every action reports whether the UI actually changed. A Mac daemon underneath hands out simulators as TTL leases with a queue and keeps a SIGSTOP warm pool, so a lease gets a live simulator in about 0.28s instead of a 7s cold boot, and multiple agents can share one Mac without colliding.
