# Weather MCP server

AccuWeather's MCP server connects AI clients such as Claude, ChatGPT, and Cursor directly to Core Weather data. Ask a question in one of those tools and it retrieves the forecast, current conditions, or alerts it needs to answer you.

It uses the [Model Context Protocol (MCP)](https://modelcontextprotocol.io), an open standard for connecting AI applications to outside data.

## What you get

All 91 Core Weather GET endpoints, available as 26 tools your client can call.

- **Nothing to switch on.** The server is live for every free trial and Elite subscriber.
- **No separate credential.** Your existing free trial or Elite API key works.
- **No separate pricing.** Each tool call counts as one Core Weather call.

## Not included

MinuteCast™ and Lightning are not served over MCP. Keep calling those over REST.
