The Foyer API Developer Hub
Welcome to the Foyer developer hub. You will find guides and reference documentation for working with Foyer programmatically — both the REST API and the MCP server that connects AI agents to a hotel.
Public API
Foyer operators can generate API keys from within the app to read their own hotel’s data over a conventional REST API.
Connect
AI agents connect to a hotel through Foyer’s MCP server. After the operator approves the connection, the agent can read and act on that hotel’s data with the scope it was granted.
