Integrations
Your PMS is the source of truth. Your mailbox stays yours.
OmniGuest reads from the systems you already run and writes back only through approval rules. Everything marked live is in production today.
01Property Management Systems
OmniGuest integrates both ways with Oracle OPERA Cloud. The PMS stays the source of truth: reservations, profiles and availability come in from OPERA, and changes go back to OPERA once a hotel has switched writeback on.
- Live
OPERA Cloud
Oracle Hospitality
Two-way via OHIP: real-time streaming in, writeback out
Business events for reservations and profiles arrive within seconds via the Oracle Hospitality Integration Platform; availability and rates are queried on demand. Bookings from e-mail, changed stays, guests, rates, extras, notes and cancellations are written back to OPERA and read back to confirm.

02E-mail
Your mail stays with your provider. OmniGuest connects with OAuth or app passwords, syncs threads and drafts replies.
- Live
Microsoft 365 / Exchange Online
Microsoft Graph, OAuth
Shared and personal mailboxes with delegated permissions and change notifications.
- Live
Gmail / Google Workspace
Gmail API, OAuth
Replies are sent through Gmail, so they appear in the guest's thread.

IMAP / SMTP
Any provider
For hosted Exchange, cPanel or local mail servers. Folder sync with idle watching.

Throttled sending that pauses on high bounce rates, with bounce and complaint suppression.
03Messaging channels
Every channel shares one conversation model and one inbox for your team.
- Live

04AI & search
Models run on OmniGuest infrastructure and are never trained on your data. By default no guest data, prompt or document goes to a public AI provider; web search queries go to public search engines.
- Live
Private language models
Self-hosted inference
Open-weight models served on OmniGuest GPUs for drafting, classification and the staff assistant.
- Live
Vision & documents
PDF, images, Office files
PDFs and Office files are indexed into the hotel knowledge base; photos and scans can be analysed in the assistant.
- Live
Speech-to-text
Whisper
Voice notes in Staff Chat are transcribed on-platform.
- Live
Full-text search
PostgreSQL
Search across guests, reservations and assistant conversations.
05AI apps (MCP)
Staff connect the AI app they already use to OmniGuest through the MCP server — read-only, off until the hotel admin switches it on, with pseudonymised guest data and every call in the audit log.
- Live
ChatGPT
OpenAI
Custom connector, OAuth
Ask about arrivals, reservations, guests, service requests and guest chats right in ChatGPT.
- Live
Claude

Other MCP apps
Remote MCP server, https://mcp.omniguest.ai/mcp
Apps that connect to remote MCP servers with OAuth, such as opencode — if the hotel allows that kind of app.
Running a PMS we haven't listed?
Tell us what you use. Our gateway approach has connected systems without an API before — a demo call is the fastest way to find out.
