NPS MCP Server

What it does

Connects your AI assistant to the National Park Service (NPS) API, enabling queries about U.S. national parks. Retrieve a list of parks in any state or fetch detailed information about a specific park — all through natural language prompts.

Tools

• park-list — Returns a list of national parks for a given two-letter U.S. state code. Provides park name, description, and park code.
• park-details — Fetches detailed information about a specific national park using its park code. Returns the full name, description, and states the park spans.

Installation

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "nps": {
      "command": "node",
      "args": ["/path/to/nps_mcp/build/index.js"],
      "env": {
        "API_KEY": "your_nps_api_key"
      }
    }
  }
}

You'll need a free NPS API key from nps.gov/developer.
