## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 76/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 499 tokens (~166/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (3)

### `check_conditions` (~167 tokens)

Live safety conditions for a place

Check live safety conditions at a coordinate on US public land: active wildfire perimeters and distance to the nearest fire, river and streamflow level against seasonal normals, advisory-grade weather in the next 7 days, open park closures and hazard alerts, and air quality. Returns a 0-100 Trip Safety Score. Call this whenever someone asks whether a place is safe to visit, whether a fire or smoke is affecting it, whether a trail or road is closed, or whether a river is runnable. It reports what was CHECKED and what is unknown separately, so absence of a warning is never presented as an all-clear.

Input parameters:

- `latitude` (number, required): Latitude in decimal degrees, -90 to 90.
- `longitude` (number, required): Longitude in decimal degrees, -180 to 180.

### `find_campgrounds` (~143 tokens)

Campgrounds near a coordinate

Find campgrounds within a radius of a coordinate across federal, state and private land, with whether each is reservable and a booking link. Call this when someone asks where to camp near a place. Returns the campground's own page so conditions and site detail can be read next.

Input parameters:

- `latitude` (number, required): Latitude, -90 to 90.
- `longitude` (number, required): Longitude, -180 to 180.
- `radius_miles` (number): Search radius in miles. Defaults to 25, max 100.
- `reservable_only` (boolean): Only campgrounds that take reservations. Defaults to false, which also returns first-come sites.

### `find_trails` (~119 tokens)

Trails near a coordinate

Find named hiking trails within a radius of a coordinate, ranked by how much is known about each rather than by raw length, so service roads and sidewalks do not lead the list. Returns distance, elevation gain, and route shape where known. Call this when someone asks what to hike near a place.

Input parameters:

- `latitude` (number, required): Latitude, -90 to 90.
- `longitude` (number, required): Longitude, -180 to 180.
- `radius_miles` (number): Search radius in miles. Defaults to 25, max 100.

## Common questions

### What is the Ranger MCP server?

Ranger is an MCP server listed in the public MCP registry as io.github.alexvesely18-dot/ranger. Live US campground availability, wildfire and river conditions, and trails on public land. This page covers its hosted endpoint (https://www.try-ranger.com/mcp).

### Is the Ranger MCP server safe to use?

Ranger scores 86 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Ranger MCP server expose?

Ranger exposes 3 tools: check_conditions, find_campgrounds, find_trails. Their descriptions and schemas cost roughly 429 tokens of context every time the server is loaded.

### Does the Ranger MCP server require authentication?

No. We connected to Ranger without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Ranger MCP server still maintained?

Ranger is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
