MCP server
Your team already uses AI apps. With the OmniGuest MCP server they connect ChatGPT, Claude or another MCP app to OmniGuest — and ask about today's arrivals, a reservation, a guest's past stays, open service requests or a guest chat. With your permissions, your hotel's rules and pseudonymised guest data.
Read-only, and off until your hotel admin switches it on.
Why hotels benefit
AI apps are only as good as what they know. The MCP server gives them your hotel's live data — under your rules, not around them.
Arrivals, a reservation, the open requests of a department: the team asks in the AI app it already knows, and the answer comes from OmniGuest. No new tool to learn.
The AI reads what is actually in OmniGuest and in the guest record OPERA Cloud keeps true, instead of inventing an answer. Every look-up is in the audit log.
Which service requests are overdue, what a guest just wrote in the chat, who arrives tomorrow with which wishes — one question, without clicking through lists.
A connection can cover several hotels of a group. Every answer says which hotel it belongs to, with that hotel's own day and time zone.
Without a sanctioned way, guest e-mails end up pasted into AI chats. With MCP the AI gets only what it is allowed, pseudonymised and on record — the hotel stays in control.
MCP is an open protocol. Your hotel is not tied to one AI provider — as more AI apps support it, they can connect the same way.
What your team asks
The AI app picks the right OmniGuest tool, OmniGuest answers from the same data your team sees in the app, and the AI turns it into a reply.
At the desk and on the floor

Which AI apps
MCP — the Model Context Protocol — is the open standard AI apps use to reach other systems. OmniGuest offers one address for every hotel and a sign-in made for it.
As a custom connector in ChatGPT Business or Enterprise, or in Pro, with developer mode switched on — in a workspace by its admin. In Pro, connectors are read-only, which is all OmniGuest needs.
As a custom connector in claude.ai and Claude Desktop on any plan — Free allows one custom connector — and in Claude Code. In Team and Enterprise, an owner adds it for the organisation.
Apps that connect to remote MCP servers with OAuth, such as opencode — if your hotel allows that kind of app.
ChatGPT is a trademark of OpenAI, Claude a trademark of Anthropic; OmniGuest is not affiliated with either. Which plans and workspaces may add custom connectors is decided by each provider and changes often — we check your setup with you during onboarding.
Set up in three steps
No installation and no IT project: one address for every hotel, and the sign-in your team already uses.
In OmniGuest under Settings → AI apps (MCP): allow AI apps for the hotel, choose which apps — ChatGPT, Claude, others — and which data they may read.
Add a custom connector with the OmniGuest address. ChatGPT: Business or Enterprise, or Pro, with developer mode switched on (in a workspace, by its admin). Claude: on any plan; in Team and Enterprise an owner adds it first.
Sign in with your OmniGuest login, passkey or two-factor included. Pick the hotels and data for this app, and whether guests appear pseudonymised. Done — ask your first question.
https://mcp.omniguest.ai/mcpWhat the AI can read
In the first version the AI can only read. It cannot change a reservation, close a ticket or write to a guest.
The hotels of the connection, with time zone and currency, so answers use the right day.
Today's or any day's movements, straight from the guest record OPERA Cloud keeps true.
Search by name, confirmation number, dates or status, and the details of one stay.
Guest search and the profile with past stays and preferences.
Open, overdue or by department — with the same visibility as in the app.
Guest chats and their messages, read without marking anything as read.
Your hotel's own documents and procedures, the same knowledge CompanyGPT uses.
Guest chat topics
Next releaseEvery guest conversation gets one of fourteen topics, assigned by OmniGuest's own self-hosted AI model — no external AI provider involved. Ask for a period and the AI app gets the number and share of conversations per topic, with short, neutral example sentences.
Statistics
Next releaseCounts, rankings and trends by day, week or month, in the hotel's time zone. The AI app only ever receives numbers, never the individual records behind them.
By period, channel, status, topic and language.
Requests and the items asked for, by department, status and completion.
On the books up to 365 days ahead: by status, room type, source, booking channel, market, length of stay, nationality and language — from the PMS data in OmniGuest (for polled connections, the synced window).
Built in
CompanyGPT, the assistant built into OmniGuest, works with the same tools, with no setup and the user's own permissions. It looks first and answers second:
How a question travels
A colleague asks a question in ChatGPT, Claude or another connected AI app.
The app calls OmniGuest with a short-lived token for this one connection.
Your permissions, your hotel's approval and the connection's choices — only what passes all three.
OmniGuest returns just what the question needs, guest data pseudonymised, and logs the call.
Security
An AI app outside your hotel reading guest data needs more than a password field. These are the rules the MCP server is built on.
Each AI app connects through OAuth with its own connection. The app never sees the colleague's password.
On the consent screen the colleague picks the hotels and modules for this app. It gets only those — even if the colleague may see more.
What the AI may read is always the overlap of three things: the colleague's permissions, what the hotel allows for AI apps, and what this connection was given.
AI apps are off until a hotel admin switches them on. The hotel chooses which kinds of app are allowed and which modules they may use.
Unless the hotel admin allows plain text, the AI sees guests as codes like G-7F3AQ2KM instead of names, and contact details are removed.
Each question the AI asks OmniGuest lands in the audit log: who, which app, which tool, which hotel and how many results — never the content of the answer.
There is no export and no copy for the AI provider. The AI app receives only the answer to the question asked, and only for the hotels and modules of its connection. What the provider does with that answer is governed by your agreement with them — that is why sending guest names in plain text needs your hotel admin's explicit consent. Free text written by guests can contain details we cannot recognise; the settings page says so before you switch anything on.
Planned
Specified for the next stage — not part of the first release.
The AI prepares a service request, a Lost & Found entry or a logbook note; anything a guest will see, and anything deleted, is confirmed by the colleague in OmniGuest first.
Ask whether an item was handed in, or what happened on the night shift — and record new entries.
Lost & Found, e-mail and logbook figures join guest chats, service requests and reservations — with the same minimum group size.
The PMS stays read-only for AI apps: nothing is written to OPERA Cloud through MCP.
Questions
The Model Context Protocol is an open standard that lets AI apps such as ChatGPT and Claude use tools in other systems. OmniGuest provides those tools; your team's AI app calls them when a question needs hotel data.
Your hotel admin switches AI apps on under Settings → AI apps (MCP). Then each colleague adds OmniGuest as a custom connector in ChatGPT or Claude with the address https://mcp.omniguest.ai/mcp, signs in with their OmniGuest login and chooses the hotels and data for that app.
No. The first version only reads. Changes with a human confirmation are planned for a later stage; the PMS stays read-only for AI apps either way.
Your hotel admin. AI apps are switched off until the admin turns them on, then the admin chooses the kinds of app and the modules. Each colleague connects their own app and can only pass on what they may see themselves.
ChatGPT, Claude — claude.ai, Claude Desktop and Claude Code — and other apps that connect to remote MCP servers with OAuth, such as opencode. Each adds OmniGuest as a custom connector. In ChatGPT that needs Business or Enterprise, or Pro, with developer mode; in Claude any plan works, and in Team and Enterprise an owner adds it first. Plans change, so we check your setup with you during onboarding.
Not by default: the AI sees guests as pseudonyms and no contact details. Plain text is possible only where your hotel admin allows it — your hotel then needs a data processing agreement with that AI provider, for example OpenAI or Anthropic.
No. Topics are assigned by OmniGuest's own self-hosted model. The AI app only receives the counts per topic and short example sentences without names, room numbers or contact details.
Only if the hotel decides so: staff statistics need their own permission and a hotel switch that is off by default. We recommend involving the works council before switching it on.
CompanyGPT, the assistant built into OmniGuest, uses the same tools. The MCP server opens them to the AI apps your team uses outside OmniGuest — with the same permissions and rules.
