Connects to Rentlio, a property management system for vacation rentals and small hotels. Muse can look up reservations, guest details and folios, check guests in, and add notes to a booking, so owners and hosts can handle front-desk questions without opening the dashboard.

Example request: "Check which guests are arriving at my rental tomorrow and add a note that the late arrival has been confirmed."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Rentlio to help me. It is a free service with an MCP server at https://rentlio.usefulapi.io/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
