Property Comps MCP Server
An MCP (Model Context Protocol) server that gives AI agents access to comparable sales data and property transactions across 16 markets in 6 countries. 43M+ records sourced from government open data registries -- not estimates, not listings.
Works with Claude Desktop, Claude Code, and any MCP-compatible AI client.

What It Does
Ask your AI assistant questions like:
- "What are comparable sales near 10001 in NYC?"
- "What's the median property price in Dubai Marina?"
- "Show me recent sales near SW1A1DA in London"
- "Compare Seattle vs Phoenix house prices"
- "What sold near 80202 in Denver last 6 months?"
The server queries official government property registries and returns real transaction data — not estimates.
