Do I need an API token to use the Corrently Energy MCP server?

No! Most Corrently API endpoints work without authentication. An optional token is only needed if you want higher rate limits for heavy usage. Simply subscribe to the server and start querying energy data immediately.

What German zip codes are supported for energy forecasts?

All German Postleitzahl (PLZ) 5-digit zip codes are supported — from 01067 (Dresden) to 80331 (Munich). Simply provide any valid German zip code and the API will return localized energy forecasts for that region's grid area.

Can I use this MCP server to optimize when I charge my electric vehicle?

Absolutely! Use the `get_best_hour` tool to find optimal charging windows based on renewable energy availability or lowest CO₂ emissions. Then use `create_energy_schedule` to generate a full optimized charging plan. You can also use `get_phev_charge_or_fuel` if you drive a plug-in hybrid and need advice on whether to charge electrically or use fuel.

How accurate are the solar generation predictions for my photovoltaic system?

The `get_solar_prediction` tool provides forecasts based on weather models and your system's kWp capacity. Accuracy depends on location, panel orientation, and weather conditions. It's best used for relative comparisons (e.g., "Will tomorrow be sunnier than today?") rather than absolute precision. For typical home systems (5-10 kWp), day-ahead forecasts are generally within 15-25% of actual generation.
