What this server can do

6 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

nps_find_campgrounds(limit, query, start, parkCode, stateCode)
Campgrounds at a park or across a state: amenities (potable water, showers, RV dump station, toilets, trash collection, RV access), reservable vs. first-come-first-served site counts, reservation guidance and booking URL, accessibility, and fees — answering "where can I camp at Zion, and can I get an RV hookup?" Get park codes from nps_find_parks. Some parks list lodging or backcountry permits instead of NPS-managed campgrounds; an empty result is not an error.
nps_find_events(query, dateEnd, pageSize, parkCode, dateStart, stateCode, pageNumber)
Scheduled events at a park within a date range — ranger programs, festivals, tours, interpretive events — answering "what's happening at Yellowstone this weekend?" with title, dates and times, location, category, fee, and registration links. Get park codes from nps_find_parks. Paginates by page number, not offset. The events feed is sparser and less consistent than alerts or campgrounds; many parks list few or no events, and an empty result is not an error.
nps_find_parks(limit, query, start, activity, stateCode)
Resolve a place name, US state, or free-text query to National Park Service parks — the required first step before the detail tools. Returns each park's parkCode (the key nps_get_park, nps_get_alerts, nps_find_campgrounds, nps_get_activities, and nps_find_events all use) plus a compact trip-planning summary (designation, states, description, coordinates, headline activities, entrance fee, NPS page). Coverage is US NPS sites only — national parks, monuments, historic sites, seashores — not state parks and not Forest Service or BLM land.
nps_get_activities(limit, query, start, parkCode, stateCode)
Curated things to do and points of interest at a park — title, description, time commitment, location, accessibility, and fee/pet/reservation flags — answering "what should I do at Acadia?" Covers the NPS editorially-curated activity list (distinct from a park's raw activity tags in nps_get_park). Accepts a single 4-letter park code or a single two-letter state code, and at least one is required. Not every park has a curated list; an empty result is not an error.
nps_get_alerts(limit, query, start, category, parkCode, stateCode)
Current alerts for a park or a whole state — closures, hazards, caution notices, and information — with category and recency surfaced first so "is anything closed at Glacier right now?" is answered at a glance. Get park codes from nps_find_parks, or pass a stateCode for a statewide "what's closed" sweep. Returns most-recent-first; an empty result with totalCount 0 means the park reports nothing closed or hazardous — good news, not an error. An empty page with a non-zero totalCount only means start ran past the end, so read the notice rather than the empty list. Closures and road conditions change daily — re-check before departure.
nps_get_park(fields, parkCode)
Full trip-planning detail for one or more parks by parkCode: description, activities and topics, entrance fees and passes, operating hours by area/season, contacts, directions, a free-text weather overview, representative images, and the NPS page for everything else. Get codes from nps_find_parks. Up to ten codes are fetched in a single request. Use the fields parameter to trim the payload when you only need certain sections. Required: parkCode.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

These share tags the maintainers applied themselves, such as travel. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
