Category Maps and Location
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability76
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2051 tokens (~293/item across 7 items; 6 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
nps_find_campgrounds national-parks-mcp-server: find campgrounds ~240
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.

No examples provided.
nps_find_events national-parks-mcp-server: find events ~330
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.

No examples provided.
nps_find_parks national-parks-mcp-server: find parks ~424
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.
| Name | Type | Req | Description |
|---|---|---|---|
| activity | string | – | Filter to parks offering an activity, matched against each park's activities list (e.g. "hiking", "camping", "stargazing"). Case-insensitive substring match, combined with query/stateCode and applied… |
| limit | integer | – | Maximum parks to return (1–50). The full set is ~470 sites; narrow with query/stateCode rather than paging through everything. |
| query | string | – | Free-text search across park names and descriptions (e.g. "yosemite", "civil war", "redwood"). Exact parkCode or name matches lead, then other name matches, then parks that only mention the term in t… |
| start | integer | – | Zero-based offset for pagination within the matched set. Use with limit to page through results. |
| stateCode | string | – | Two-letter US state/territory code, or comma-separated list (e.g. "CA", "WY,MT,ID"). Filters to parks located in those states. Combine with query to narrow. |

| shown | number | – | Number of parks returned in this response (populated when the result set was capped by limit). |
| totalCount | number | – | Total parks matching every filter, before start/limit were applied. |
| truncated | boolean | – | True when more parks matched than this response returned; absent on a complete result. |
No examples provided.
nps_get_activities national-parks-mcp-server: get activities ~253
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum activities to return (1–50). |
| parkCode | string | – | A single 4-letter lowercase park code (e.g. "acad"). Get it from nps_find_parks. Accepts one park code, not a list. Provide parkCode or stateCode. |
| query | string | – | Free-text search across activity titles/descriptions (e.g. "sunrise", "hike", "tour"). |
| start | integer | – | Zero-based pagination offset. |
| stateCode | string | – | A single two-letter state code (e.g. "ME"). Returns curated activities across NPS sites in that state. |

| shown | number | – | Activities returned in this response (populated when capped by limit). |
| totalCount | number | – | Total activities matching the filter before the limit was applied. |
| truncated | boolean | – | True when more activities matched than this response returned; absent on a complete result. |
No examples provided.
nps_get_alerts national-parks-mcp-server: get alerts ~401
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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Filter to one alert category. "Danger" and "Park Closure" are trip-affecting. Combined with parkCode/stateCode/query and applied before start/limit, so totalCount counts every matching alert, not one… |
| limit | integer | – | Maximum alerts to return (1–50), most-recent first. |
| parkCode | string | – | Park code, or comma-separated list (e.g. "glac", "yose,zion") — 4-letter lowercase codes. Get codes from nps_find_parks. Provide parkCode or stateCode; with neither, returns recent alerts service-wid… |
| query | string | – | Free-text search within alert titles/descriptions (e.g. "road", "wildfire", "trail"). |
| start | integer | – | Zero-based offset for pagination within the matched set. Use with limit to page through results — when totalCount exceeds what was returned, re-request with start advanced by limit. |
| stateCode | string | – | Two-letter state code, or comma-separated list (e.g. "MT", "WY,MT,ID"). Returns alerts for all NPS sites in those states — use for a statewide sweep rather than one park. |
| Name | Type | Req | Description |
|---|---|---|---|
| alerts | array | – | Current alerts, most-recent first. Empty with totalCount 0 means no active alerts match the request; empty with a non-zero totalCount means start ran past the end of the matches. |
| appliedFilters | string | – | Echo of parkCode/stateCode/category/query as applied. |
| cap | number | – | Limit applied (populated when results were truncated). |
| categoryBreakdown | string | – | Count of returned alerts per category, most severe first (e.g. "Park Closure: 3, Caution: 1, Information: 2"). |
| error | object | – | Present when the call failed. Absent on success. |
| notice | string | – | Guidance on the result set: whether an empty page means no active alerts match (totalCount 0) or start ran past the end of the matches, the start value for the next page when more alerts matched, and… |
| shown | number | – | Alerts returned in this response (populated when capped by limit). |
| totalCount | number | – | Total alerts matching the filter before the limit was applied. |

nps_get_park national-parks-mcp-server: get park detail ~193
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.
| Name | Type | Req | Description |
|---|---|---|---|
| fields | array | – | Optional detail sections to include beyond the always-present core (name, designation, states, description, coordinates, weather, url). Omit for all sections. Narrow to reduce payload when you only n… |
| parkCode | array | yes | One to ten park codes per call, each a 4-letter lowercase code (e.g. "yose", "grca", "zion"). Get codes from nps_find_parks. |
| Name | Type | Req | Description |
|---|---|---|---|
| error | object | – | Present when the call failed. Absent on success. |
| missingCodes | array | – | Requested park codes that matched no NPS site — likely misspelled. Populated only when some codes did not resolve. |
| notice | string | – | Guidance when one or more codes did not resolve, or when none did. |
| parks | array | – | Requested parks with trip-planning detail. |
| requestedCount | number | – | Number of park codes requested. |
