Altegio MCP servers put salon booking data in ChatGPT and Claude

Your booking software is turning into an AI data source. On November 10, Altegio, a salon and spa management platform used by more than 14,000 businesses, announced an open platform of MCP servers at Web Summit in Lisbon. A salon owner can now plug bookings, visit history and revenue into ChatGPT or Claude and ask questions in plain English. The useful part is real. The risky part is the write access.

What actually happened

From Altegio's announcement:

• Six MCP apps. Pro MCP (manage bookings, staff, services, schedules, clients), a read-only Pro MCP for analytics, an in-app Analytics Agent, a Knowledge MCP over the help center, an Integrations Hub MCP for developers building from Cursor or Claude Code, and Altegio.me MCP so customers can book, reschedule or cancel from their own AI assistant.
• Setup. Copy a connection URL, add it as a custom connector in your assistant, approve access in the browser. Features vary by assistant and plan.
• Guardrails. The assistant gets only the permissions of the user's Altegio account. Read, write and delete are set separately, and the assistant asks for confirmation before it saves a change.
• API v3 (early access). Personal API keys that inherit the creating user's current permissions and lose access when that user's access is revoked, plus password-free authorization for partner apps. The existing API has more than 200 methods.
• Scale. Altegio says it handles 5.5 million bookings a month and runs on Hetzner data centers in Germany.

Why it matters for your business

"Which clients haven't visited in 90 days?" used to be a report export and a spreadsheet. Now it's one question. That's a real time saving for an owner who does the books at 10 p.m.

But an MCP connection with write access is an employee with no training. Our rules:

1. Connect the read-only server first. Analytics questions don't need write access. Give the assistant the bookkeeper's view, not the owner's.
2. Use a dedicated Altegio user for the connector. Since keys and connectors inherit that user's permissions, scope the user. Don't connect your owner account.
3. Treat customer-side booking as a channel. If Altegio.me MCP lets clients book through their own assistants, your service names, durations and cancellation policy have to be clear enough for a machine to read.
4. Check where the data goes. The data sits in Germany. Your assistant's chat history may not. Read your AI vendor's retention terms before you paste client lists into it.
