How do I calculate the number of blocks needed for my wall?

You can use the `calculate_block_count` tool. Provide the total surface area of your wall, the type of block you are using (such as `hollow_9x19x39`), and an optional waste percentage.

How much mortar do I need for the joints and plastering?

Use the `calculate_mortar_volume` tool. You will need to provide the wall area, the block type, and the thickness of the coating layer.

Can I estimate how much cement and sand to buy?

Yes, by using the `estimate_raw_materials` tool. Once you have the total mortar volume from the previous step, input that volume and your desired mix ratio (e.g., '1:3') to get the required quantities.

This MCP server provides specialized tools for construction estimation. Use calculate_block_count to determine the number of blocks needed based on wall area and block type, including waste margins. Use calculate_mortar_volume to calculate both bedding and coating mortar volumes. Finally, use estimate_raw_materials to convert total mortar volume into specific quantities of cement and sand using a provided mix ratio.
