Use onOffice with AI via MCP
In the brokerage business, daily work lives in the CRM: listings, prospects, viewings, feedback. With the AI Connector, onOffice provides its own MCP server, which CompanyGPT connects to as a remote integration – no extra infrastructure required.
What is onOffice?
onOffice enterprise is CRM and brokerage software from onOffice GmbH in Aachen. It manages properties, contacts and prospects, produces exposés, drives publication to real estate portals and covers the process from acquisition to closing. Its Marketplace extends the system with specialized third-party applications.
onOffice is relevant for AI agents because property and contact data converge there in structured form. Questions such as which prospects match a new listing, or which activities are documented for a given contact, can be answered in conversation instead of being assembled from filters and lists.

How to Connect onOffice to CompanyGPT
With the AI Connector, onOffice provides its own MCP server – according to the vendor, the first MCP server of a real estate CRM. You generate the individual MCP server URL in the Marketplace under AI Connector → setup and then register it as a connector in CompanyGPT. No additional software runs on your side or at a third party.
The prerequisite is activation in the onOffice Marketplace; the AI Connector is available from the All-In plan upwards. Because the MCP URL is generated per customer, access is tied unambiguously to your tenant. Independently of this, the classic onOffice enterprise API with token, secret and HMAC signature remains available for special cases.
In CompanyGPT, your administrators decide by role and group who may use the onOffice integration – in practice usually sales and back office. Traffic flows directly between your CompanyGPT instance and the onOffice endpoint, with no intermediary services.
