## What it does

This hosted server adds two tools to search public real estate records. One tool queries active, pending, or sold listings using filters like price and bedroom count. The second tool pulls in-depth property records, including tax history, school ratings, and HOA fees.

You do not need to host Docker containers or scrape HTML manually. The service runs over remote HTTP at `https://mcp.hasdata.com/mcp?apis=redfin`. For clients limited to stdio, wrappers exist on npm as `@hasdata/redfin-mcp` and PyPI as `hasdata-redfin-mcp`.

Requests require an active `HASDATA_API_KEY`. Without this token passed via headers or environment variables, tool calls will fail immediately. HasData grants 1,000 monthly credits with no card on sign-up, which covers 100 tool queries at 10 credits each.

## Requirements
- Needs: Node.js (commands run via npx)
- Remote server: `https://mcp.hasdata.com/mcp?apis=redfin`
- Environment variables: `HASDATA_API_KEY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
