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.
