What it is: the cheapest data MCP to try
RentCast has records on over 150 million US properties, updated with about 500,000 changes a day. The MCP exposes all four data groups in its API:
| Data | What your AI can ask for |
|---|---|
| Property records | Structure, features, tax assessments and taxes, sale history, current owner details |
| Valuation | A value estimate and a rent estimate (AVMs) with a range and the comparable properties behind them |
| Listings | Active for-sale and for-rent listings in all 50 states: price, status, days on market, MLS number, listing agent |
| Market data | Average sale prices and rents, listing statistics and history by ZIP (38,000+ ZIP codes) |
Setup
RentCast's documented steps:
- Get an API key from your RentCast API dashboard (the free plan works).
- Add
https://developers.rentcast.io/mcpas a custom connector in Claude. Cursor, VS Code, Claude Code and JetBrains use the config RentCast gives. - For live data, pass your key in the
X-Api-Keyheader, or give it when Claude asks in the chat.
In Claude Code it's one command:
claude mcp add --transport http rentcast https://developers.rentcast.io/mcp --header "X-Api-Key: YOUR_API_KEY"

Who should use it

Questions
Is the RentCast MCP free? Connecting is free and includes 50 requests a month, then requests bill at your plan's rate.
Does it work in ChatGPT? RentCast documents only Claude, Claude Code, Cursor, VS Code and JetBrains, though ChatGPT's paid custom connectors should accept it.
Can it find the owner of a property? It returns owner details from property records, but doesn't skip trace for phone numbers.
