The Guesty API caps you at five access tokens per client ID per 24 hours, and each token lasts 24 hours. That one limit decides your architecture: anything that mints a token per process start, per agent session, or per serverless invocation exhausts the budget within hours. Guesty also ships an official MCP server in early beta, read-only during the beta, so for conversational access start there.
The token limit that decides your architecture
According to Guesty's Open API documentation (guesty.com), the API authenticates with OAuth 2.0 client credentials, and availability depends on your Guesty plan tier. The constraint that matters is not the auth flow but the quota. Guesty allows only five access tokens per client ID per 24 hours, and each issued token remains valid for 24 hours.
This breaks the most natural way to write an integration. An MCP server starts fresh every time the assistant launches. A serverless function may cold-start dozens of times an hour. An agent that re-authenticates per session burns a token each time. Five of any of those and you are locked out until the window rolls.
The fix is simple once you know it: mint the token once, store it, and reuse it for its full 24-hour life.
Guesty's official MCP server
Guesty ships an official MCP server in early beta. It is read-only during the beta, labeled experimental, and available locally through the Guesty SDK or hosted. For asking questions about your listings and reservations inside an assistant, use it: it is first-party. For a tool that runs unattended, you want the API and the token caching above.

Quick FAQ
Does RapidEye work with Guesty?
Yes. RapidEye sets up the connection to Guesty for your account. Tell us which platform you use and we take it from there.
How do you get API access to Guesty?
Guesty API access uses OAuth 2.0 client credentials, and availability depends on your Guesty plan tier. The critical operational limit: Guesty allows only five access tokens per client ID per 24 hours, and each token is valid for 24 hours, so tokens must be cached rather than minted per process start.
Can AI assistants connect to Guesty officially?
Yes, in early beta. Guesty ships an official MCP server, available locally through their SDK or hosted, and it is read-only during the beta and labeled experimental. If your goal is asking questions inside an assistant, that is the right tool and it is theirs.
Why does a Guesty integration need token caching?
Because five tokens per client ID per 24 hours is a hard ceiling. An MCP server restarts whenever the assistant launches, serverless functions cold-start constantly, and agents re-authenticate per session. Any of those patterns minting a fresh token exhausts the daily budget in hours, which is why the token must be minted once and reused for its full 24-hour life.
