Questions

What can the AI do in RentCast?

The AI can search and read US property records, get value and long-term rent estimates with comparables, search and read sale and rental listings, and read market statistics for a zip code. All tools are read-only.

Does the AI see my RentCast credentials?

No. Your RentCast credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, for example estimates without listing searches. All RentCast tools only read data. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own RentCast account with an active API plan, and each lookup counts as a request on that plan.

Can the AI change anything in RentCast?

No. RentCast's API is for looking things up, so the AI can only search and read property records, estimates, listings and market data. Nothing is created or changed.
