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 Security80
- 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 check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability76
- AI-judged instruction clarity (excellent).Pass
- 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. 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. 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 →
check_conditions Live safety conditions for a place ~167
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.
| Name | Type | Req | Description |

| latitude | number | yes | Latitude in decimal degrees, -90 to 90. |
| longitude | number | yes | Longitude in decimal degrees, -180 to 180. |
No output schema declared.
No examples provided.
find_campgrounds Campgrounds near a coordinate ~143
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.
| Name | Type | Req | Description |
|---|---|---|---|
| latitude | number | yes | Latitude, -90 to 90. |
| longitude | number | yes | 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. |
No output schema declared.
No examples provided.
find_trails Trails near a coordinate ~119
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.
| Name | Type | Req | Description |
|---|---|---|---|
| latitude | number | yes | Latitude, -90 to 90. |
| longitude | number | yes | Longitude, -180 to 180. |

How do I install the Ranger MCP server?
Ranger is a hosted endpoint at https://www.try-ranger.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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.
