Prime Calendar, Flozic and Composio for AI booking
These three get compared because they all touch AI and bookings, but they are different things. Flozic is a booking agent that talks to your customers. Composio is a toolkit layer for building your own agents. Prime Calendar is the calendar and booking system, with an MCP server your AI tools can connect to.

Where Prime Calendar makes more sense
You want your assistant to work with your real calendar, tasks and bookings. Agents sign in with OAuth and get a permission group, so you decide what they can read and change.
Getting started
- In Prime Calendar, create an agent and pick its permission group, or connect your AI app with OAuth.
- Use https://api.primecal.eu/api/mcp as the MCP server URL.
- Start with a read-only group and widen it once you trust the setup.
Where they are the better pick
If you want a ready-made agent that answers in chat, by voice or through a web form, that's Flozic. If you're building your own agents and need lots of integrations, Composio lists more than 1,500 toolkits.
Isn't MCP everywhere now?
It is spreading. FlowSavvy, Routinery and Composio all advertise it. The difference is what sits behind it: ours is the calendar itself, bookings and permissions included.
Start on Free to look around. Store turns on booking, resources and the organisation account.
