Buildability™ — AI Property Intelligence

Six Weeks, Two People, One MCP Server

Data version: Q2 2026 · Last updated 2026-05-13

TL;DR. How we built the Buildability™ MCP server in six weeks with a two-person team. Tech stack, tradeoffs, and lessons learned.

Summary

The Buildability™ MCP server went from idea to production in six weeks with a two-person team. Stack: Node.js, TypeScript, Supabase edge functions, Claude Opus for analysis, GPT-4o for cross-validation, Gemini for structured extraction. Tradeoffs: we chose correctness over speed on ambiguous cases (flag and explain instead of guess). Biggest lesson: real government APIs are messy and inconsistent — the hardest work was data normalization, not AI.
