Ranger MCP
Ranger MCP provides tools to check live safety conditions like wildfires and river levels, find reservable campgrounds, and locate hiking trails on US public land. It distinguishes between verified availability, directory entries, and informational listings.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

check_conditions — 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.

}find_campgrounds — 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.

}find_trails — 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.
