# 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.

| Tool | Description |
|------|-------------|
| `search_property_comps` | Search comparable sales by location and radius. Returns prices, dates, addresses, property types, and statistics. |

## Setup — Claude Desktop
Add to your `claude_desktop_config.json`:
```json
{
"mcpServers": {
"property-comps": {
"command": "python",
"args": ["path/to/mcp_server.py"]
}
}
}
```
On macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
On Windows: `%APPDATA%\Claude\claude_desktop_config.json`
## Setup — Claude Code
```bash
claude mcp add property-comps python /path/to/mcp_server.py
```
## How It Works
The server auto-detects the market from your location format:
| Input | Detected Market |
|-------|----------------|
| `SW1A1DA` | UK (postcode pattern) |
| `10001` | NYC (ZIP code range) |
| `75001` | France (postal code range) |
| `310093` | Singapore (6-digit code) |
| `Dubai Marina` | Dubai (area name) |
| `20001` | Washington DC (ZIP range) |
| `98115` | Seattle (ZIP range) |
| `85004` | Phoenix (ZIP range) |
| `80202` | Denver (ZIP range) |
| `15222` | Pittsburgh (ZIP range) |
| `Greenwich` | Connecticut (town name) |
| `Dublin` | Ireland (county name) |
| `Taipei` | Taiwan (city name) |
You can also specify the market explicitly: `market="uk"`, `market="nyc"`, etc.

## Data
All comparable sales data comes from official government open data registries. Updated monthly. Every result is an actual recorded property transaction — not an estimate, not a listing price. The same government sources that banks and surveyors rely on for valuations.
