Create and Modify Visitor Schedules via MCP Server

Your agent can create appointments by calling `create_group_visit`, requiring structured JSON data for the name, scheduled date, expected attendees, host ID, and location. For changes, use `update_group_visit` with the specific group visit ID. If a meeting is canceled, you must call `delete_group_visit`. Pydantic ensures that the required fields are present before the API accepts the request.

Manage On-Site Check-ins and Guest Data

To check someone in, your agent executes `create_signin`, providing the visitor name, host ID, location ID, and purpose. To review history, use `list_signins` to get records including check-in time, check-out time, and visit purpose. If a record needs correction, you can call `update_signin` with the specific sign-in ID.

Setup Security Features and Host Profiles

The agent makes setting up staff easy. Use `create_host` or run `create_hosts_batch` to onboard new employees. For security, you can create a watchlist using `create_watchlist`, defining its name and description. Reviewing available sites is done with `list_locations`. This tool returns all necessary location IDs for subsequent actions.
