**Give your AI assistant real weather data — 17 tools, zero API keys, zero signup, zero cost.**

Weather MCP is a [Model Context Protocol](https://modelcontextprotocol.io) server that connects AI assistants (Claude, Cursor, Cline, Zed, and any other MCP client) to live weather data: forecasts, current conditions, alerts, air quality, marine conditions, lightning, radar, rivers, wildfires, and 85+ years of historical weather. It's built entirely on free public data sources — NOAA, Open-Meteo, USGS, NIFC, NASA FIRMS, RainViewer, and Blitzortung.org — so there is nothing to sign up for and no key to paste in. (A few optional keys unlock extras — see [Optional API keys](#optional-api-keys) — but no tool ever requires one.)

claude mcp add weather -- npx -y @dangahagan/weather-mcp@latest

That's the whole install for Claude Code. For any other MCP client, add this to its MCP config:

{
  "mcpServers": {
    "weather": {
      "command": "npx",
      "args": ["-y", "@dangahagan/weather-mcp@latest"]
    }
  }
}

Then just ask:

*"What's the weather in Tokyo this weekend?"* *"Is there any lightning near the lake right now?"* *"How does today compare to normal for this time of year?"* *"Are there wildfires within 50 miles of my cabin?"* *"Will there be a full moon this weekend?"* *"Is this a record high for toda
