Who it is for
Hosts running direct bookings on their own domain, and guests who want an offer traceable to that domain.
Host-domain verified vacation rental offers
Overview
HemmaBo works with vacation rentals booked through a host's own domain rather than a listing site. It verifies those domains and handles bookings against them, and it is aimed at two situations: a host who wants a booking engine on their own site, and a guest who wants an offer signed by the host's domain.
The Vacation Rental Protocol behind it is an open specification for such signed offers. The app exposes fifteen runtime tools in total: eleven federation tools, two for onboarding a host, and two that carry out VRP verification.
The listing is explicit about the boundaries. HemmaBo is not an online travel agency, not a marketplace, and not a website builder.
Hosts running direct bookings on their own domain, and guests who want an offer traceable to that domain.
It is built on an open protocol for signed offers instead of an inventory marketplace.
Availability
HemmaBo is listed in the ChatGPT apps directory only. HemmaBo has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from HemmaBo's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with HemmaBo, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
