Launch a local Chromium routed through a residential proxy exit in a chosen country (and city/state on the Elite tier). Returns a session_id the other aethyn_* tools use. Each session is one sticky identity — a pinned exit IP for the whole task.
aethyn_navigate
Navigate the session's browser to a URL and wait for load. Returns the HTTP status, final URL, and page title — read the page with aethyn_get_content to judge the response yourself. Public data only — respect robots.txt, rate limits, and each site's terms.
aethyn_get_content
Return the current page's content cleaned for reading (markdown by default). Use after navigating to extract data.
aethyn_snapshot
Return a structured accessibility snapshot (roles, names, and [ref=..] handles) of the page. Pass those refs to aethyn_click / aethyn_type. No screenshots needed.
aethyn_click
Click an element. Prefer a 'ref' from aethyn_snapshot (e.g. 'e12'); or pass a 'selector' (CSS, or Playwright role=/text= engine).
aethyn_type
Type text into an input. Prefer a 'ref' from aethyn_snapshot; or a 'selector'. Set submit:true to press Enter after.
aethyn_check_exit_ip
Fetch IP info THROUGH the session's proxy so you can verify the exit country/city actually landed before trusting the page. Returns ip, country, city, org/ASN, and a best-effort is_residential flag.
aethyn_new_identity
Rotate the session to a fresh residential exit (new IP, same country) and clear cookies. Use between independent tasks or after a soft-block.
aethyn_close
Close the session's browser context and free memory. Call this when a task is done.
aethyn_list_countries
List available exit countries (and Elite-tier cities where known). Discover geo options at runtime before launching.
