National Parks Mcp Server

cyanheads/national-parks-mcp-server

Six read-only tools wrap the NPS Data API, so you can go from a state or free-text query to a trip plan without leaving your agent. The flow starts with nps_find_parks to resolve a place to a parkCode, then nps_get_park batches up to ten codes for fees, hours, and directions. nps_get_alerts surfaces closures and hazards sorted by recency, nps_find_campgrounds reports reservable versus first-come site counts, nps_get_activities pulls curated things to do, and nps_find_events covers date-bounded programming. It runs over stdio or Streamable HTTP and needs an NPS_API_KEY. Reach for it when a planning agent needs current park conditions. Park coordinates can also feed a weather server for forecasts.
