Claude Code: deny. ### `waitwhile_cancel_visit` - The name "waitwhile_cancel_visit" says "cancel": a word for removing or ending something. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text WRITE: cancel ONE visit (a waitlist entry or booking). Waitwhile sets its state to COMPLETE and adds the CANCELLED tag; the visit is kept, not deleted. By default the request asks Waitwhile to suppress the customer message; this may only stop the immediate cancellation notice, and scheduled reminders/follow-ups can still go out per the location's settings. With send_notifications=true Waitwhile may text/e-mail this ONE customer. POST /visits/{visitId}/cancel. ``` ### `waitwhile_create_visit` - The name "waitwhile_create_visit" says "create": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text WRITE: create ONE visit at a location. Without a date it adds the customer to the waitlist; with a local date-time (YYYY-MM-DDThh:mm) it creates a booking. Needs a location and at least a name, phone or e-mail. Not idempotent: calling it twice creates two visits. Visit notes are not supported here (the field is deprecated): use waitwhile_add_customer_note. By default the request asks Waitwhile to suppress the customer message; this may only stop the immediate confirmation, and scheduled reminders/follow-ups can still go out per the location's settings. With send_notifications=true Waitwhile may text/e-mail this ONE customer. POST /visits. ``` ### `waitwhile_update_visit` - The name "waitwhile_update_visit" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text WRITE: change ONE visit — its state (e.g. WAITING to SERVING to COMPLETE, or BOOKED), add/remove tags (e.g. ARRIVED, CONFIRMED, NO-SHOW), booking date/duration or party size. Only the fields you pass change. By default the request asks Waitwhile to suppress the customer message; this may only stop the immediate status message, and scheduled reminders/follow-ups can still go out per the location's settings. With send_notifications=true Waitwhile may text/e-mail this ONE customer. Use waitwhile_cancel_visit to cancel. POST /visits/{visitId}. ``` ## Changes things (4) Creates or changes something that can be changed back. Claude Code: ask. ### `waitwhile_add_customer_note` - The name "waitwhile_add_customer_note" says "add": a word for a change.

POST /customers/{customerId}/notes. ``` ### `waitwhile_first_available_slots` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Use it to propose appointment times. GET /visits/first-available-slots. ``` ### `waitwhile_resources_availability` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

GET /resources/availability. ``` ### `waitwhile_visit_analytics` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
