The request asks for a real-estate search tool without naming a product. Several sources offer property listing data through APIs or MCP servers: RealtyCrawl aggregates listings across 202 sources 1, Stream.Estate offers 50M+ listings from 1,500+ sources 2, SimplyRETS provides MLS listing data via API 4, and HouseData offers Zillow listings and records via API and MCP 6. Note that the country or market (US, France, Germany, Portugal) is not stated, and listing coverage differs by source.
A question back: Which country or market do you need listings for, and do you want listings for sale, rent, or both?
