Nationalparks MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. MCP Server for the National Park Service (NPS) API, providing real-time information about U.S. National Parks, including park details, alerts, and activities.
@smithery/cli on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Once Nationalparks is connected, these are the calls the assistant has available:
Inputs — - stateCode (optional string): Filter parks by state code (e.g., "CA" for California). Multiple states can be comma-separated (e.g., "CA,OR,WA")Returns — Matching parks with detailed informationYou will need 2 environment variables: NPS_API_KEY, YOUR_NPS_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Nationalparks's toolset — Inputs, Returns — is a fair guide to whether it matches your workflow. It is maintained by KyrieTangSheng; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
