MCP server

Your calendar, right in Claude and ChatGPT.

Connect Zitli to your AI assistant with the Model Context Protocol (MCP). Ask what's coming up, find free slots and share the right booking link – and on Pro, let it confirm or cancel bookings, block days off and update your hours, without opening the app.

What you can ask

Your assistant picks the right Zitli tool and answers in your time zone.

  • “What's on my calendar this week?”

  • “Which 30-minute slots are free on Thursday afternoon?”

  • “Send me the booking link for my intro call.”

  • “Which bookings are still waiting for my confirmation?”

  • “Ask my 14:00 client tomorrow to pick a new time.”

  • “Cancel my 10:00 appointment tomorrow.”

  • “Block 22 to 26 December – I'm on holiday.”

  • “From now on, I only work mornings on Fridays.”

  • “Create a 45-minute appointment type for follow-ups.”

Privacy and control

Your assistant sees only what it needs

Zitli shares as little as possible with AI apps, and you can end the connection at any time.

Manage connected AI apps

  • Only the access you approve

    When you connect, you see exactly what the app may do: read your profile, appointment types, bookings or availability – or change bookings, availability and appointment types.

  • Minimal booking data

    Attendees appear with name and email only. Meeting links, phone numbers and addresses are never passed to the AI.

  • Nothing changes without asking

    Zitli instructs your assistant to check with you before it accepts, cancels or changes anything. Your AI app may also ask you to approve each action.

  • Disconnect at any time

    Settings › Connected AI apps lists every connected app. One click disconnects it and access ends immediately. Access tokens expire after 30 minutes anyway.

  • No content in our analytics

    We only count which tool was used and whether it worked – never your questions, bookings or results.

  • Hosted in the EU

    The MCP server is part of the Zitli app and runs on the same EU-hosted infrastructure as your bookings.

FAQ

Questions about AI assistants

Yes. On Free, your assistant can read your profile, booking page, bookings, free slots, schedules and blocked days. Pro and the 14-day trial also let it manage bookings, availability and appointment types. If you change plans, the change applies to the next request.
