How does the volume calculation work?

The `calculate_harvest_volume` tool multiplies your roof area by the average monthly rainfall for your city and then applies an efficiency factor based on whether your system is rated as low, medium, or high efficiency.

Can I estimate financial savings?

Yes, by using the `calculate_savings_estimate` tool, you can input the volume of water you expect to harvest and your local utility's tariff tier (residential, premium, or industrial) to see the estimated monetary savings.

Which cities are supported?

The system currently supports major global cities such as London and New York. You can use `get_monthly_rainfall` to check if your specific city is available in the database.

More Details Connect to Claude

This MCP server provides a specialized engine for calculating the potential of rainwater harvesting systems. By connecting your AI agent to local precipitation data, you can accurately estimate how many liters of water can be captured from a specific roof area using calculate_harvest_volume. Additionally, the tool calculate_savings_estimate allows you to project financial savings on municipal water bills by applying different utility tariff tiers. Use get_monthly_rainfall to verify historical precipitation averages for supported cities like London or New York before performing complex calculations.
