Casa Layer unifies guest data from every system you run — PMS, POS, spa, loyalty, reviews — into one canonical, tenant-scoped record. One guest. One memory. One place to read it from. Your guest history lives scattered across the systems that captured it. Casa Layer pulls those fragments together, resolves them into a single golden record per real guest, and exposes that view through two read surfaces — so dashboards, internal tools, and AI assistants all see the same guest.

REST API

Tenant-scoped JSON over HTTP for dashboards, internal tools, and integrations. The full data model, read-only.

MCP Server

A Model Context Protocol server so AI assistants can read guest context with the same API keys and tenant isolation.
