• get_route_briefs · Compare up to six known routes in one compact evidence packet: grade, timing conflicts, selected equipment, linked huts, access, notices and optional dated daylight. Preserves per-route errors and source provenance. Partial results must not
• get_capabilities · Inspect actual catalogue coverage, output JSON schemas, data version, units and unsupported operations before planning. Unknown data is not evidence of absence.
• get_notices · Read dated notices with publication validity, explicit scope uncertainty and recurrence hints. Supply slug and the trip date; omitted date means today (UTC), echoed in requestedDate. Expired notices may describe recurring regulations; expir
• resolve_peak · Resolve a canonical peak ID, external Wikidata/OSM ID, current slug or exact name to its current slug and citable URL. Example input: {"id":"Ben Nevis"}. Use canonical IDs to recover from renamed slugs.
• get_changes · Compare a watched set of peaks with a previous snapshot. Returns content changes, removals and an updated snapshot. No changes means no new source data, not proof that conditions are unchanged. Date-dependent notice status must still be che
• get_daylight · Compute sunrise, sunset and civil twilight for the exact calendar date and IANA zone. UTC instants handle daylight saving and polar days. Terrain and weather can reduce usable daylight.
• search · Search peaks.fyi by mountain name, alternative name, country, range or climbing request. Returns citable peak IDs and URLs. Use fetch to read a result; use search_peaks for explicit filters and pagination. An empty result means no match in
• fetch · Read a peak search result by catalogue slug as a citable text document. Example input: {"id":"ben-nevis"}. This retrieves catalogue documents, not external website URLs; use your own browsing tool for publisher pages. Includes routes, seaso
• get_peak · Get compact peak facts and route IDs. Example input: {"slug":"ben-nevis"}. Optionally request access, huts, seasons, hazards or provenance sections. For fact questions search may already suffice. For current weather use get_weather; for hut
• get_route · Get one route by peak slug and routeId from get_peak: grade, equipment, key passages, stages, trailhead, timing, confidence and geometry QA. Failed, truncated or outline geometry must not be used for navigation. Times are estimates. No live
• get_route_point · Look up a named waypoint or difficult passage on a route. Returns source notes, known coordinates, nearby stage names, key passages and relevant equipment. Missing coordinates or conditions remain unknown; this is not live navigation guidan
• get_huts · Read huts, documented seasonal operation, source years and booking/contact URLs for a peak. Beds means capacity, never vacancies. Live availability, reservations, rental inventory and current opening status are unknown. Do not infer next ye

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
