get_access_and_permitsread-only

Returns the permit entry and road access shown on a route's forecast page for a covered objective: the permit status, fee, notes and official link, and the road conditions for the approach passes, with highway, temperature, restrictions, the road agency named and the time its data was fetched. Road data older than 30 minutes is marked. Informational only.

get_alertsread-only

Returns the NPS park alerts and National Weather Service fire weather alerts displayed for a covered objective, with source attribution and retrieval timestamps. ClimbCast does not carry current USDA Forest Service alerts or closures. Informational only.

get_forecast_accuracyread-only

Returns stored public regional forecast accuracy, including observed-station or model-proxy truth lineage, data sufficiency, and eligibility. Takes either a region_id or an objective slug, which resolves to the accuracy region of the NWAC zone the objective is bound to. Informational only.

get_hourly_conditionsread-only

Returns the two-hourly temperature, wind speed, and wind direction shown in the hourly view of the forecast page's weather by elevation grid, for one day in the free forecast window, with local times, ISO timestamps, the time zone, and the chosen elevation. Takes a date from the route's visible days and an optional elevation band of base, mid, or summit. Informational only.

get_objective_conditionsread-only

Returns public conditions for a covered objective: summit weather, the objective page's route list with grade, type, and round-trip distance, source provenance, and timestamps, in JSON or markdown. Covers up to five days. Daylight and air quality appear for the first day only, and get_trip_brief carries the per-day values the forecast page shows. Informational only.

Returns up to five days of public route conditions, anchored to the route high point, with catalog gain, source provenance, and timestamps. An optional activity input selects one of the route's activities listed by search_objectives.

list_areasread-only

Lists the public coverage areas shown on the coverage directory, with each area's slug, name, state or province code, and visible activities. An area is a fixed geographic definition, not a distance from the caller. Its slug is the optional area input of search_objectives. Informational only.

search_objectivesread-only

Searches the public coverage catalog by name or alias, with optional region and activity filters. Coverage follows the current public scope. Region filters include WA, OR, and BC. Results list each objective's slug and route IDs with their activities, which the other tools take as inputs. An optional area input limits results to the objectives the coverage directory lists under that area. Query an
