Devuelve `amount` (lo que se cobra ahora: total o anticipo) y `balanceDue` (lo que pagará en el establecimiento). Verifica que el slot siga libre antes de cobrar. La CITA SE CREA SOLA cuando el pago se aprueba — no llames create_event después. Para cobrar el saldo de una cita ya reservada con anticipo usa settle_event_balance (mostrador). Servicios sin cobro en línea devuelven error.

Input parameters:

- `customer` (object, required)
- `payChoice` (string): Sólo para servicios donde el cliente elige cómo pagar. 'on_site' NO genera link.
- `serviceSlug` (string, required)

### `get_sales` (~121 tokens)

Cuánto DINERO entró en un rango: total, desglose por servicio, por método de pago y saldos pendientes. Imputa por FECHA DE COBRO. No es comparable con get_org_stats ni get_today_summary, que cuentan por fecha de la CITA: que no cuadren no es un error, son dos preguntas distintas. Nunca los sumes ni los restes entre sí.

Input parameters:

- `from` (string): ISO o YYYY-MM-DD. Default: hoy.
- `to` (string): ISO o YYYY-MM-DD. Default: hoy.

### `add_agenda_block` (~142 tokens)

Aparta un rato de la agenda para que nadie pueda reservarlo: comida, junta, vacaciones. No es una cita — no lleva cliente ni servicio. Pasa `end` o `duration`; si no, dura una hora.

Input parameters:

- `allDay` (boolean): Bloquea el día completo.
- `duration` (number): Minutos. Default 60.
- `end` (string): Fin en ISO (alternativa a duration).
- `start` (string, required): Inicio en ISO. No se redondea.
- `title` (string): Qué es: 'Comida', 'Junta', 'Vacaciones'. Default 'Bloqueado'.

### `settle_event_balance` (~125 tokens)

Registra el cobro del SALDO pendiente de una cita que se reservó con anticipo. Sólo métodos de mostrador (cash|transfer|card): no genera un link de pago. El monto que falta ya está en la cita (`balanceDue` de get_event), no se especifica aquí. Entra al corte de caja del día de HOY, no al día de la reserva. Requiere aprobación del dueño.

Input parameters:

- `eventId` (string, required)
- `method` (string): Cómo pagó. Si se omite, se registra como efectivo.

### `discover_tools` (~139 tokens)

Busca entre TODAS las herramientas de Denik, incluidas las que no están en tu lista. Úsala antes de decirle al usuario que no puedes hacer algo. Sin `query` ni `domain` devuelve el catálogo completo. Lo que encuentres se ejecuta con `run_tool`.

Input parameters:

- `domain` (string): Filtro por área. Sirve para inventariar un dominio completo.
- `limit` (number): Máximo de resultados (default 25).
- `query` (string): Qué buscas, en español y con las palabras del usuario (ej. 'recordatorios', 'bloquear horario', 'cuánto vendí').

### `run_tool` (~105 tokens)

Ejecuta cualquier herramienta de Denik por su nombre, esté o no en tu lista. Los `params` son los del `inputSchema` que devolvió `discover_tools`. Si la respuesta trae `error: needs_confirmation`, la acción NO falló: quedó esperando la aprobación del dueño, que la ve en esta misma conversación. No reintentes.

Input parameters:

- `name` (string, required): Nombre exacto de la herramienta.
- `params` (object): Argumentos de esa herramienta.

### Is the Denik MCP server still maintained?

### What licence is the Denik MCP server under?

Denik declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
