Sign in to mountaineers.org. Opens a Chrome window where YOU complete the login (your password is never sent to this server or the AI); it then caches your session. Required once before any other tool works — mountaineers.org blocks unauthenticated clients. Re-run when a tool reports your session has expired. Requires a desktop with Google Chrome (stable channel) installed; the call blocks for up to ~3 minutes while you sign in. If you're already signed in from a previous run, it may finish in seconds.

Search currently-published outdoor activities on mountaineers.org (upcoming trips, course field trips, clinics). Supports filtering by type, branch, difficulty, date range, and more. Past activity instances are NOT in the search index — if you have a known historical activity URL use get_activity, or use get_member_history for a member's past activities.

Search currently-published courses, clinics, and seminars on mountaineers.org (upcoming and rolling-enrollment only). Past course instances (prior years) are NOT in the search index, even though their URLs still resolve — if you have a known historical course URL use get_course, or use get_my_courses for the authenticated user's past courses.

Search trip reports on mountaineers.org. Trip reports are member-written accounts of past outings; the full historical archive (8000+ reports) is searchable here. To narrow to a specific route, pass the route name as the query.

List trip reports filed against a specific route/place URL. Paginated, 20 per page; results follow the site's default order (typically newest first). Use this when you have a route URL and want member-written reports for that route specifically — more accurate than searching trip reports by route name.
