Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@open-meteo-mcp What's the weather in Moscow this week?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
MCP server for Open-Meteo — free weather APIs, no API key required.
16 tools covering weather forecast, historical data, air quality, marine, flood, ensemble, climate projections, and scheduled data collection
Scheduled jobs — server-side cron, persists readings to SQLite, returns aggregated stats
No auth — Open-Meteo is free for non-commercial use

| GloFAS river discharge forecast, up to 16 weeks |
| Multi-model ensemble with uncertainty quantification |
| CMIP6 climate projections 1950–2050 |
| ECMWF SEAS5 seasonal forecast up to 9 months |
| DWD ICON model — high-res for Europe |
| ECMWF IFS model — gold standard global forecast |
Tool | Description |
| Compare named cities on a date → ranked by weather quality score |
| Center city + radius km → grid sample → best spot in the area |
Score factors: sunshine, temperature comfort (18–28°C sweet spot), precipitation, wind, UV.
Example prompts:
"Moscow, Sochi, Kazan this Saturday — where's best?" → compare_weather_cities
"Best weather within 300 km of Moscow next Sunday?" → compare_weather_region
Tool | Description |
| Create a recurring data collection job (cron expression) |
| List jobs with schedule, status, and reading count |
| Aggregated stats (min/max/avg) over a time window |
| Stop and delete a job |
Scheduled jobs survive server restarts — state is persisted in ~/.open-meteo-mcp/data.db.
