# real_estate_intel

Real estate intelligence aggregator with a best-in-class French dataset (DVF — Demandes de Valeurs Foncières — 100% of FR transactions since 2019, public, keyless) plus UK Land Registry Price Paid (all UK transactions 1995+). Four modes: (1) property — full transaction history for a specific address; (2) comparables — median/std price/m² within a radius (default 500m); (3) market — annual price series, YoY change, volume, trend by commune; (4) valuation — two-method estimate (comparables median + hedonic regression if n≥30) with confidence scoring (high/medium/low). All sources are free and require no API key. ICP: PropTech agents, REITs, fund managers, family offices, insurance. SLA: ≤25s p95 (sources fetched in parallel, 8s budget each). Cache: 24h TTL (DVF data is stable). Quality score: 30 pts DVF retrieved, 20 pts geocoding, 20 pts UK LR retrieved, 15 pts if comparables count ≥10, 15 pts if method quality achieved. Status: failed/<60/≥60 → failed/partial/final. No env vars required.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `mode` | string | yes | property: transactions at an address \| comparables: sample around a point \| market: commune/neighbourhood market stats \| valuation: price estimate for a given s |
| `async` | boolean | no | If true, returns a job_id immediately (<200ms) instead of waiting for the result. Poll the result with job_result(job_id). Use for slow tools to avoid client ti |
| `date_to` | string | no | ISO date YYYY-MM-DD — latest transaction date |
| `location` | object | yes | Location descriptor. One of: {address, city?, country?} \| {lat, lon, radius_m?} \| {insee_code} for FR communes. |
| `date_from` | string | no | ISO date YYYY-MM-DD — earliest transaction date |
| `max_results` | number | no | Maximum number of results to return (5–50, default 20) |
| `surface_max` | number | no | Maximum surface in m² (±20% tolerance applied for comparables) |
| `surface_min` | number | no | Minimum surface in m² (±20% tolerance applied for comparables) |
| `property_type` | string | no | Filter by property type (default: all) |

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "real_estate_intel",
    "arguments": {
      "mode": "<mode>",
      "location": {}
    }
  }
}
```

## Why real_estate_intel is rated Low

This tool retrieves and aggregates publicly available real estate transaction data from open government datasets (French DVF, UK Land Registry). All four modes are read-only queries — fetching transaction history, computing comparables, analyzing market trends, or estimating valuations. No data is created, modified, deleted, or financially committed. Severity is low because misuse would only expose public data.

From the tool's own definition: "real estate intelligence aggregator... Four modes: (1) property — full transaction history for a specific address; (2) comparables — median/std price/m²; (3) market — annual price series; (4) valuation — two-method estimate. All sources are free"

Risk signals: High parameter count (16 properties)

## Use case

AI agents call real_estate_intel to retrieve information from Gapup Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
