How do I calculate the maximum water I can collect?

You can use the `get_theoretical_yield` tool by providing your roof area in square meters and the rainfall depth in millimeters.

Can I check if my rain barrel is big enough?

Yes, use the `evaluate_barrel_capacity` tool with your expected volume and the barrel's capacity to see if it will overflow.

What is collection efficiency?

It is a decimal value (0 to 1) representing the fraction of rain that actually enters the barrel, accounting for losses like evaporation or absorption.

This MCP server provides tools to calculate how much water can be captured from a roof. Use get_theoretical_yield to find the maximum possible volume, get_actual_yield to account for collection efficiency, and evaluate_barrel_capacity to check if your storage is sufficient. You can also use compare_material_efficiency to see how different roofing materials impact your total yield.
