Summary
Gives Claude 81 construction calculators and live federal cost data traced to building codes (IRC, IBC, NEC, IECC, IPC) and manufacturer specs. Query concrete yardage with ACI 318 coefficients, pull BLS wage data for carpenters by county, or look up product specs from the 40,000+ item catalog. Every response cites its source. The streamable HTTP transport at api.buildcalcapi.dev/mcp works in Claude Desktop or Cursor with OAuth 2.1. Useful when you're building estimators, spec assistants, or anything that needs grounded construction numbers instead of LLM guesses. Free tier gives you 1,000 calls monthly to test before committing.
