Tools

23 tools agents can invoke

Book one slot as the authenticated customer, but only when the service's current price is zero. First call list_available_slots and echo its schedule_version, terms_fingerprint and selected slot's review_fingerprint. Generate a fresh mutation_id UUID for each intended booking and reuse it only when retrying that same booking. Creating the appointment can notify participants in Schemon and by email.
book_free_appointment
Cancel an appointment that belongs to the authenticated customer or their owned provider business. Call get_appointment first and cancel only when allowed_actions includes 'cancel'; echo its current version as expected_version. Providers must supply a reason. Customers may cancel a confirmed appointment only before its cancellation deadline. Generate a fresh mutation_id UUID for each intended cancellation and reuse it only when retrying that same cancellation. Cancelling can notify the counterpart in Schemon and by email.
cancel_appointment
Add a comment to an accessible project task. The other board participant may receive a Schemon notification.
add_project_task_comment
Create a note in a note space returned by list_note_spaces. SHARED notes are visible to both sides and notify the counterpart. PRIVATE notes are permitted only for the provider.
create_note
Create a task on an accessible project board. Position is zero-based within the selected fixed column and is clamped to the valid range.
create_project_task
Create a future reminder in a provider workspace. Omit recipient_id for a self-reminder; otherwise the recipient must be a valid participant on the opposite side of the same workspace. When due, the reminder is delivered in Schemon and can also be sent by email.
create_reminder
Return the profile belonging to the authenticated Schemon user.
get_profile
Return how the authenticated user is positioned in Schemon: which portal sides apply ('provider' when they own a business or are staff, 'customer' when they are a client of one), the business they own, the businesses they are linked to, and unread notification/message counts per side. Call this first: most other Schemon tools need a 'side' argument and this is the only way to know which values are valid.
get_context
Return the full record of one appointment the authenticated user is a party to, including the terms captured at booking time, payment status, video meeting state, recent status history and the actions the user may take right now. 'version' is the optimistic-concurrency token any future mutation must echo back.
get_appointment
List tasks in one accessible project board. Results can be filtered by column, priority, assignee, label, archive state, or search text.
list_project_tasks
List the bookable services of a business. Omit provider_slug for the business the authenticated user owns; pass it for a business they are a customer of (see linked_providers in get_context). 'bookable' false means new appointments are refused and 'booking_error' says why.
list_services
Return the free start times for one service, day by day, in the provider's own timezone. 'date' is the first local day and 'days' extends the window up to 7 days. An empty day with unavailable_reason set means the service itself cannot be booked; an empty day without one simply has no free time. schedule_version, terms_fingerprint and each slot's review_fingerprint are the values a booking call has to echo back, so keep them with the slot.
list_available_slots
List the authenticated user's appointments on one portal side. Use get_context first to learn which sides are valid: 'customer' returns bookings the user made, 'provider' returns bookings made with the business they own. 'bucket' is the filter to prefer — 'pending' awaits the provider's decision, 'upcoming' is confirmed and not finished, 'past' is over, 'cancelled' covers cancelled/rejected/expired. bucket_counts always describes the whole side, ignoring the filter. Newest start time first.
list_appointments
List the authenticated user's provider-customer conversations on one portal side, including unread counts and last-message previews.
list_conversations
List the provider-customer workspaces in which the authenticated user can read or create notes. Use the returned space id with list_notes or create_note.
list_note_spaces
List notifications for one Schemon portal side. Use get_context first to choose customer or provider. This tool does not mark notifications as read.
list_notifications
List project boards visible to the authenticated user on one portal side. Use a returned board id with the project task tools.
list_project_boards
List reminders visible to the authenticated user on one portal side. Pending reminders are returned in due-time order.
list_reminders
List notes visible to the authenticated user in one note space. Customers see shared notes; the provider also sees their private notes.
list_notes
Move a task to a fixed board column and/or a zero-based position. At least one of column or position is required.
move_project_task
Read newest-first messages in a conversation returned by list_conversations. Reading through MCP does not change the portal's read watermark.
list_messages
Send a plain-text message in a conversation returned by list_conversations. MCP message sending does not support attachments.
send_message
Partially update a task. Use clear_due_at or clear_assignee to remove those values, and pass an empty label_ids list to remove all labels.
update_project_task
