Run instant property valuations in Windsurf Cascade

`get_sale_valuation` pulls accurate, real-time estimated values for any residential property using the RentCast database. Cascade reads your target address, calls this tool, and immediately chains the result into your underwriting model. No manual data entry or switching tabs required. You don't have to guide your agent through the process. Once you set a target acquisition yield, Cascade uses the valuation output to calculate cap rates and cash-on-cash returns on its own.

Run automated rental market analysis

`get_rental_comparables` finds active and historical rent listings near your target property to establish realistic market rent. Your agent matches these comps by radius, bedroom count, and property type without needing your constant supervision. This lets you build dynamic pricing models directly inside your workspace. Cascade compares the outputs from `get_rental_valuation` with actual active listings to flag overvalued properties before you waste time on deeper analysis.

Track local market shifts with this MCP Server

`list_market_trends` tracks ZIP-code level metrics like median list prices and active inventory counts over time. Windsurf monitors these macro shifts to adjust your portfolio's projected exit valuations dynamically. The agent connects these trends with raw property details from `get_property_details`. You get a clear picture of localized price appreciation and inventory pressure without writing custom scrapers.

Common questions about RentCast MCP in Windsurf

Open your Windsurf settings and head to the Cascade MCP panel. Paste the Vinkius connection URL into your config file, click refresh, and Cascade immediately discovers all eight property valuation tools.

Yes, Cascade is built for autonomous execution. It will run `get_property_details` first, grab the building size, and then pass that data straight into `get_rental_valuation` to output a clean yield report.

The server uses `list_active_listings` to pull real-time rental market data. Windsurf parses these active listings to build live spreadsheets or update your internal databases on the fly.

No, Vinkius handles the authorization layer for you. You use a single secure endpoint token to access all RentCast endpoints, meaning your agent never exposes your raw API keys in the workspace.
