Key Capabilities
Stream instant valuations to your Vercel AI SDK UI
The `get_rental_valuation` tool calculates real-time rental estimates, feeding raw numbers straight to your user's screen. Your AI client pulls this data without forcing the user to stare at a blank loading state. By coupling `get_sale_valuation` with Vercel's streaming capabilities, you show property values step-by-step. Users see the exact comps and pricing models populate the interface as they generate.
Pull local rental comps directly in Edge Functions
The `get_rental_comparables` tool fetches active and historical neighborhood matches to justify pricing decisions. It runs inside lightweight Edge runtimes, keeping latency under 50 milliseconds during peak traffic. When your agent executes `get_sale_comparables`, it filters nearby sales by distance and square footage. This JSON payload feeds directly into your UI components without heavy backend processing.
Track local housing trends with this MCP Server
The `list_market_trends` tool retrieves localized real estate metrics using only a ZIP code. It gives your application immediate access to median listing prices and inventory shifts. You can combine this with `list_active_listings` to build dynamic dashboards that update as the agent researches. No complex database setup is required, since Vinkius secures the connection.
