## MCP tools (7)

### `consultar_cpe` (~94 tokens)

Consultar una carta de porte

Datos completos de una carta de porte electrónica a partir de su CTG: grano, pesos, estado, fechas y los CUIT que intervienen. Incluye los pesos tomados en la balanza del destino, que son los que sirven para conciliar contra balanza propia.

Input parameters:

- `nroCTG` (string, required): Número de CTG (Código de Trazabilidad de Granos) de la carta de porte

### `cpes_recibidas_en_planta` (~186 tokens)

Cartas de porte recibidas en una planta

Cartas de porte que LLEGARON a una planta propia dentro de un rango de fechas. Es la consulta del que recibe la mercadería, no del que la despacha: ARCA exige el número de planta y no ofrece el listado inverso. Quien solo despacha no puede usar esto. Por defecto devuelve un resumen (totales por grano y las 20 más recientes); pedir detalle solo para rangos cortos, porque una campaña entera son cientos de cartas.

Input parameters:

- `desde` (string, required): Fecha de partida desde, YYYY-MM-DD
- `detalle` (boolean): Si es true, lista todas las cartas en vez del resumen.
- `hasta` (string, required): Fecha de partida hasta, YYYY-MM-DD
- `planta` (integer, required): Número de planta de destino. Obligatorio: ARCA rechaza la consulta sin él.

### `tipos_de_grano` (~58 tokens)

Tabla de códigos de grano

Códigos de grano que reconoce ARCA hoy, consultados en vivo. Útil para traducir el código que trae una carta de porte, y para descartar códigos de planillas viejas que el organismo ya no reconoce.

### `ultimo_nro_orden` (~84 tokens)

Último número de orden de CPE

Último número de orden de carta de porte emitido para una sucursal y tipo de CPE. Sirve para detectar saltos de numeración.

Input parameters:

- `sucursal` (integer): Número de sucursal. Default: 0.
- `tipoCPE` (integer): Tipo de CPE. Default: 74 (carta de porte automotor).

### `consultar_padron` (~98 tokens)

Consultar el padrón por CUIT

Razón social, estado de la clave fiscal, domicilio fiscal, forma jurídica y actividad principal de un CUIT. Sirve para saber contra quién se está operando. El régimen impositivo (monotributo vs. general) solo aparece si el certificado tiene habilitado el alcance A5 del padrón, que se pide aparte en ARCA.

Input parameters:

- `cuit` (string, required): CUIT a consultar, con o sin guiones

### `consultar_comprobante` (~91 tokens)

Consultar un comprobante emitido

Detalle de un comprobante ya emitido: importes, IVA, CAE y estado. Solo consulta: no autoriza comprobantes ni pide CAE.

Input parameters:

- `numero` (integer, required): Número de comprobante
- `puntoVenta` (integer, required): Punto de venta
- `tipoComprobante` (integer, required): Tipo de comprobante (1 = Factura A, 6 = Factura B, ...)

### `estado_servicios` (~57 tokens)

Estado de los servicios de ARCA

Chequea si los servidores de ARCA están respondiendo. No usa el certificado ni consulta datos de nadie: es lo primero que conviene mirar cuando algo falla, para separar una caída del organismo de un problema de credenciales.
