Campsite Availability MCP Connector for Claude

Give up to eight campground ids separated by commas and a month like "2026-07"; each row reports the site count, how many days hold at least one open site, the date with the most open sites and the first open arrival. A campground that errors is reported in its own row with the reason instead of failing the comparison, so a bad id does not lose the rest. Use this after search_campgrounds has given the ids, and before drilling into one campground with get_monthly_availability. Campsite availability of several campgrounds side by side for one month — which one has open sites, how many, and on which dates

Give the campground id, a month like "2026-11" and the length of stay; the answer lists every arrival date in the month where at least one site is Available for all consecutive nights of the stay, with how many sites qualify on each date. A one-night stay reports the same nights as the open columns of the month table; longer stays are stricter, so a month with plenty of single nights open can still have no three-night window. An empty list means the month is before the release window, closed for the season, or fully booked — check get_monthly_availability to tell which, because it reports reserved and closed days rather than just open ones. Which arrival dates in a month have a site free for a whole stay — the calendar view of when a campground can actually be booked

Holds the description, facilities, natural features, nearby attractions, accessibility notes, fees, stay limit, cancellation policy, contact phone and directions. This is the descriptive record only — it says nothing about whether a site is free on a given night, so pair it with get_monthly_availability or find_available_sites for that. The full record of one Recreation.gov campground — what it has, what it costs, how to get there and the rules that apply

Give the campground id and a month like "2026-11"; the month is normalised to its first day, which the API requires. The answer is an aggregation over the per-site grid the site publishes: one row per arrival date with open, reserved, closed and other counts, a breakdown by campsite type, and a paginated site list where each site carries the longest run of open nights it has that month — the number to look at when a stay needs more than one night. A campground with no published inventory for the month says so: it may be first-come-first-served, closed for the season, or before the release window (Recreation.gov opens reservations on a rolling basis, roughly five months out, so a far-future month can legitimately be empty). Page the site list with offset; the day table always covers the whole month. Campsite availability for one campground across a whole month — how many sites are open, reserved or closed on each arrival date, and which sites are free at all

Search a park or campground name — "Upper Pines", "Yellowstone", "Joshua Tree" — and matching is on the name as Recreation.gov holds it, so a fragment is enough. The list also contains tours, permits and timed-entry listings, which this tool drops: only campgrounds come back, which is why a page can hold fewer rows than you asked for. Page through results by advancing offset by page_size, not by the number of rows returned. Optional state is a two-letter code and is matched here, not by the site, so with a state filter each page holds fewer rows still. Rows carry the campground id to hand to get_campground, get_monthly_availability and find_available_sites. Find campgrounds on Recreation.gov by name — the campground inventory of the US national parks and forests, with the facility id every other tool needs

Give the campground id, an arrival date like "2026-11-20" and the number of nights; a site is returned only when it is Available on every night of the stay, because a booking needs one site free for all of them. A stay that crosses a month boundary is handled by fetching both months, so a "2026-11-28" arrival for three nights works even though it ends in December. Each site carries its number, loop, type and sleeping capacity. An empty answer means every site is blocked on at least one night — shorten the stay, move the arrival, or use find_available_dates to see which arrivals in the month do work. Nights cap at 14. The campsites at one campground that are free for an entire stay — every night from the arrival date through the departure
