Nothing serious here today
Today is the operative word: we check National Parks MCP Server every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

nps
nps_find_campgrounds
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. Check the linked campground page for RV hookups and date-specific availability. 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
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. Many parks list few or no events; an empty result is not an error.
nps_find_parks
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
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
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 no active alerts match the request (with category or query set, alerts outside that filter may still be active); an empty page with a non-zero totalCount means start ran past the end of the matches. Closures and road conditions change daily.
nps_get_park
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. Accepts up to ten codes per call. Use the fields parameter to return only the sections you need.

National Parks MCP Server — questions
Answers built from our own checks of this server.
What can National Parks MCP Server do?
It exposes 6 tools, read directly from the server on our last check. Among them: nps_find_campgrounds, nps_find_events, nps_find_parks, nps_get_activities, nps_get_alerts, nps_get_park. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is National Parks MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 583 ms. The bar chart above shows every period we have measured.
How do I connect National Parks MCP Server?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does National Parks MCP Server need an API key?
No. National Parks MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is National Parks MCP Server?
It answers our handshake in 583 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use National Parks MCP Server?
The npm package @cyanheads/national-parks-mcp-server was installed 162 times in the last week. Week over week that is -75%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is National Parks MCP Server open source?
The code is open source: it is published under the Apache-2.0 licence, written in TypeScript, 3 stars on GitHub and 2 open issues. The licence covers the code in the repository, not the hosted service at national-parks.caseyjhand.com, which runs on its operator's own terms.
