What is the MCP Weather MCP server?

If you want an AI assistant working directly with MCP Weather, the mcp weather mcp server is the bridge. MCP server that provides hourly and daily weather forecasts using the AccuWeather API.

What MCP Weather does

A Model Context Protocol (MCP) server that provides hourly and daily weather forecasts using the AccuWeather API.

This MCP server allows large language models (like Claude) to access real-time weather data. When integrated with an LLM, it enables the model to:

Installing the mcp weather mcp server

The server is distributed via npm as @timlukahorstmann/mcp-weather, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Configuration

Before the server will start you need to supply one environment variable: ACCUWEATHER_API_KEY. Keep credentials in your client's env block or a secrets manager rather than committing them.

Requirements

  • Node.js ≥18 - An AccuWeather API key (set via .env or your shell)

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. MCP Weather sits in that group. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • It will not start until its required credentials are present, so set those before wondering why the tools never appear.
  • Maintained by TimLukaHorstmann, written in Go.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the mcp weather mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

How to install the MCP Weather MCP server
