Assessment: Meteosource's MCP server is a small, clear weather toolset, seven tools covering forecasts, alerts, air quality, history and renewable production, with error messages that tell the agent what to do. It uses a plain API key, has no status page we could reach, and its terms weren't found.

## Before you call it

1. Call search_places first to resolve a location
2. Split history requests over 400 location-days into shorter ranges
3. Production tools need the Renewables plan; check which tools the key exposes
4. Send the key in a header, never in a URL

## Connect

```bash
claude mcp add meteosource --transport http https://mcp.meteosource.com/mcp --header "Authorization: Bearer $METEOSOURCE_API_KEY"
```
