How accurate are the cost estimates?

Estimates are based on hardcoded baseline indices for the 50 largest US cities, adjusted by structural and usage multipliers. For a complete breakdown, use `estimate_total_lag` to see how all variables interact.

Which cities are supported?

The server supports the 50 largest US metropolitan areas. You can verify a specific city's availability using `city_base_index_lookup`.

Can I estimate costs for different building materials?

Yes, the engine accounts for various structural types. Use `material_multiplier_fetch` to see how wood, steel, or concrete affects your final estimate.

More Details Connect to Claude

This MCP server provides a precise estimation engine for construction projects in the United States. By connecting AI agents to localized economic data, it allows for detailed cost projections based on city-specific base rates, structural material multipliers (such as material_multiplier_fetch results), and building usage intensity. Use city_base_index_lookup to find baseline rates, or run a complete calculation with estimate_total_burden by providing the city, square footage, material type, and usage category.
