## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% +updated-12d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 84/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: nps_find_parks (destructiveHint, idempotentHint); nps_get_park (destructiveHint, idempotentHint); nps_get_alerts (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 2,484 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 6 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know @cyanheads/national-parks-mcp-server@0.2.1, @cyanheads/national-parks-mcp-server@0.2.1

- tools: 6, about 2,484 tokens to load them all
- tool set hash: a13e23e508c83e2ccb56bd1973d86206
- tools last changed: 2026-09-24T10:08:14.747Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.cyanheads/national-parks-mcp-server.svg)](https://protogrid.dev/servers/io.github.cyanheads/national-parks-mcp-server)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-24 `nps_find_events` changed (description, inputSchema, outputSchema)
  - before: 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.
  - after: 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.
- 2026-09-24 `nps_get_activities` changed (inputSchema, outputSchema)
- 2026-09-24 `nps_find_campgrounds` changed (outputSchema)
- 2026-09-24 `nps_get_alerts` changed (description, inputSchema, outputSchema)
  - before: 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.
  - after: 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.
- 2026-09-24 `nps_get_park` changed (description, inputSchema, outputSchema)
  - before: 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.
  - after: 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.

## Tools (6)

- `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 — 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`: 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.
