What is the Open Meteo MCP MCP server?

If you want an AI assistant working directly with Open Meteo MCP, the open meteo mcp mcp server is the bridge. Model Context Protocol server for Open-Meteo weather APIs.

What Open Meteo MCP does

A comprehensive Model Context Protocol (MCP) server that provides access to Open-Meteo weather APIs for use with Large Language Models.

Tools it exposes

Once connected, the assistant can call these 2 tools directly:

  • Requirements — The Requirements tool exposed by this server
  • Releasing — This project uses automated releases via GitHub Actions. To create a new release:

Installing the open meteo mcp mcp server

The server is distributed via npm as open-meteo-mcp-server, 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 8 environment variables: OPEN_METEO_API_URL, OPEN_METEO_AIR_QUALITY_API_URL, OPEN_METEO_MARINE_API_URL, OPEN_METEO_ARCHIVE_API_URL, OPEN_METEO_SEASONAL_API_URL, OPEN_METEO_ENSEMBLE_API_URL, OPEN_METEO_GEOCODING_API_URL, OPEN_METEO_FLOOD_API_URL. Keep credentials in your client's env block or a secrets manager rather than committing them.

Requirements

  • Node.js >= 22.0.0

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. Open Meteo MCP sits in that group, and the shape of its toolset — Requirements, Releasing — tells you what it is really for. 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 cmer81, written in TypeScript.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the open meteo mcp 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.
