Tools & Capabilities Breakdown

Aethyn Browser MCP Tools (10)

aethyn_launch_browser

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.
