How to integrate Open-Meteo using MCP

Free weather forecasts, no API key. This guide creates an MCP server from Arthur's Open-Meteo template — tools preconfigured against https://api.open-meteo.com/v1 — and finishes by sharing the server's MCP swagger documentation.

Steps

  1. Go to the REST API Templates gallery and search for Open-Meteo.

    Open the REST API template gallery

    Search the gallery for the Open-Meteo integration

  2. Click Use template on the Open-Meteo card to open the server-creation dialog.

    Open the Open-Meteo template with its preconfigured tools

  3. Review the server name — the dialog lists every tool that will be created.

    Name the server after the integration it provides

  4. Click Create server. Arthur creates the server, applies the authentication, and generates all the tools.

    Create the Open-Meteo server with its preconfigured tools

  5. Open the server's Tools tab to review the generated tools.

    Review the tools generated from the Open-Meteo template

  6. Open the server's Connect section and click Share the MCP swagger documentation — Arthur generates the public documentation link and QR code for this server.

    Open the server's Connect section, where the MCP endpoint and its documentation live

    Open the MCP swagger documentation share panel

    Show the generated swagger documentation link and QR code for this server

Confirm it worked

The server appears with 3 preconfigured tool(s): get_current_weather, get_forecast, get_historical_weather. The Connect section offers the MCP swagger documentation — a shareable page with setup instructions for any AI client.

Good to know

  • High-accuracy weather forecasts and historical climate data for any location using latitude and longitude. Completely free and open-source — no registration or API key required.
  • No authentication required — the server is ready to use immediately.
  • Official API documentation: https://open-meteo.com/en/docs
  • Editing a tool later never changes the template — templates are starting points, and the server is fully yours after creation.
