Documentación del servidor MCP

Cómo conectar Cefidia a Claude u otro asistente de IA, qué puede hacer y qué cuesta. Al final está la referencia de las 50 herramientas, generada de la misma definición que el servidor publica en tools/list, así que siempre está al día.

Qué es

Cefidia emite facturas electrónicas CFDI 4.0 desde un cliente MCP: le pides a tu asistente de IA (Claude u otro) que facture, y él prepara el borrador, lo timbra con el PAC y te entrega el XML y el PDF. También registra complementos de pago, notas de crédito y cancelaciones, y consulta tus facturas, receptores, productos y catálogos del SAT.

Requisitos

Una cuenta de Cefidia.
Un emisor registrado, con su CSD (Certificado de Sello Digital) subido en el navegador. El CSD nunca pasa por el chat: las herramientas dan la liga de la página donde se sube.
Crédito de timbrado para timbrar. Los borradores, los catálogos y las consultas no cuestan nada.

Conectar

URL del servidor

https://cefidia.com/mcp

Claude (claude.ai, Claude Desktop y la app móvil)

En Configuración → Conectores, elige Agregar conector personalizado y pega la URL del servidor. La primera vez Claude abre una ventana para que inicies sesión con tu cuenta de Cefidia. El conector queda disponible en todos los dispositivos donde uses esa cuenta de Claude.

Claude Code

claude mcp add --transport http cefidia https://cefidia.com/mcp

Cualquier otro cliente MCP

Agrega un servidor MCP remoto (HTTP) con la URL del servidor e inicia sesión con OAuth en la ventana que abre el cliente. No se necesita ID ni secreto de cliente: el cliente se registra solo. Para los clientes que aceptan una configuración JSON:

{
  "mcpServers": {
    "cefidia": {
      "url": "https://cefidia.com/mcp"
    }
  }
}

El servidor habla MCP sobre HTTP (Streamable HTTP): un único endpoint que recibe peticiones JSON-RPC 2.0 por POST y sólo expone herramientas.

Permisos

Al conectar, el cliente te lleva a iniciar sesión en Cefidia (OAuth 2.1 con PKCE y registro dinámico de clientes, RFC 7591) y recibe un token con permisos (scopes). Cada herramienta exige uno; sin él, la llamada responde con el error insufficient_scope. Los documentos de descubrimiento están en /.well-known/oauth-protected-resource y /.well-known/oauth-authorization-server.

Permiso	Qué permite	Herramientas

En Claude, las herramientas que crean, cambian o borran datos piden tu confirmación antes de ejecutarse. Puedes ver los asistentes conectados y desconectar cualquiera en Conexiones; la desconexión aplica a toda tu cuenta, y un asistente desconectado deja de funcionar hasta que lo vuelvas a autorizar.

Qué cuesta

Sólo dos cosas gastan crédito de timbrado: timbrar con sign_cfdi, y que un receptor timbre un borrador desde la liga que generó request_receiver_data.
Todo lo demás es gratis: borradores, consultas, catálogos, descargas de XML y PDF.
create_account_topup_link no cobra nada por sí misma: sólo genera la liga de pago, y la recarga ocurre si tú la pagas.
cancel_cfdi es definitiva: la cancelación queda registrada en el SAT y no se puede deshacer.

Ejemplos

Algunas peticiones que puedes hacerle a tu asistente, con las herramientas que suele usar para resolverlas:

«¿Qué facturas emití este mes y cuáles siguen con saldo pendiente?»

Herramientas: list_issuers, list_cfdi, get_invoice_balance
«Factura a mi cliente Comercializadora Ejemplo 10 horas de consultoría a $1,500 más IVA, pagadas en una sola exhibición por transferencia, y timbrala.»

Herramientas: list_issuers, list_receivers, list_products, search_sat_catalog, create_invoice_draft, sign_cfdi
«Mi cliente pagó hoy $5,000 por transferencia de la factura PPD que le emití el mes pasado; haz el complemento de pago y timbralo.»

Herramientas: list_issuers, list_cfdi, get_invoice_balance, create_payment_complement_draft, sign_cfdi
«¿El servicio está disponible y cuánto crédito de timbrado me queda? Si es poco, dame una liga para recargar.»

Herramientas: get_service_status, list_issuers, get_account_credit, create_account_topup_link
«Abre un ticket de soporte: el PDF de mi última factura no muestra el logotipo.»

Herramientas: create_support_ticket, list_support_tickets

Datos

Por cada llamada, el servidor guarda sólo el nombre de la herramienta, el resultado (correcto o error) y el código de error, con la fecha, el cliente y el emisor; nunca los argumentos ni las respuestas. Ese registro lo ves en Registros. Lo que las herramientas crean o cambian (emisores, facturas, receptores, productos) se guarda en tu cuenta igual que si lo hicieras en la aplicación web.

Los detalles están en el Aviso de Privacidad.

Soporte

Desde el propio asistente puedes abrir un ticket con create_support_ticket, ver los tuyos con list_support_tickets y get_support_ticket, y responder con add_support_ticket_message. Soporte nunca necesita tus archivos del CSD, su contraseña ni tus tokens.

Referencia de herramientas

Elegir el emisor

Una cuenta puede tener varios emisores (RFC). Cada herramienta que actúa por un emisor lleva su id en el argumento obligatorio issuer, aunque la cuenta tenga un solo emisor; list_issuers da los ids. Sin él, o con un id que no es de uno de tus emisores, la respuesta es el error issuer_selection_required con la lista de emisores entre los que elegir. list_issuers, get_service_status, register_issuer y las herramientas de soporte no necesitan emisor.

Errores

Los errores de una herramienta llegan como resultado con isError: true y un texto JSON con error (el código) y message.

`get_service_status` Consultar estado del servicio

Permiso: issuers:read

Check whether the service is ready to use, in one read-only call; works with no issuer and takes no issuer selection. Returns {service: {status: available|interrupted, message?}, setup: {complete, issues: [missing_issuer | missing_csd | incomplete_theming, each with where it is resolved: missing_issuer carries setup_url, the page where the user registers their issuer and uploads its CSD (register_issuer also creates the issuer; its CSD is then uploaded in the browser), missing_csd carries upload_url, the page where the CSD is uploaded in the browser]}, balance: {billing: on, balance, currency, stamp_price, stamp_currency, stamps_affordable (the folios left), bonuses (top-up bonus tiers)} or {billing: off}, notifications: [{id, severity, message}]}. Nothing can be issued (created, updated or signed: an invoice, credit note or payment complement) while service.status is interrupted or setup.issues has a missing_issuer or missing_csd, and nothing can be signed while the balance does not cover a stamp. notifications are the service's current notices, and setup lists what is left to set up.

Sin argumentos.

`register_issuer` Registrar razón social

Permiso: issuers:write

Register a new issuer (a business that issues invoices) for the caller, who becomes its owner. Works with no issuer yet and takes no issuer selection. It takes the fiscal data only: rfc, business_name, fiscal_regime (SAT c_RegimenFiscal key, e.g. 601) and lugar_expedicion (5-digit postal code). The CSD (certificate, private key and password) is uploaded in the browser at the returned upload_url, the issuer's page; this tool never receives it, and the issuer cannot issue until it is uploaded. Returns {id, rfc, business_name, has_active_csd: false, upload_url}.

Argumento	Tipo	Descripción
`rfc` requerido	`string`	The issuer's RFC (12 or 13 characters)
`business_name` requerido	`string`	Legal name, as on the SAT
`fiscal_regime` requerido	`string`	c_RegimenFiscal key, e.g. 601

`list_issuers` Listar razones sociales

Permiso: issuers:read

`create_support_ticket` Create support ticket

Permiso: issuers:write

Open a support ticket with the Cefidia team for the caller: a problem, a question or a request about the service. Works with no issuer and takes no issuer selection. Support works from the details in the title and description: what was tried, the invoice id or the error code returned. Support staff read the ticket; support never needs CSD files, key passwords or tokens. Support answers inside the ticket, and nothing is pushed to the caller: get_support_ticket returns the answers. Returns {ticket: {id, title, description, state, created_at, updated_at, messages}}; the id is what get_support_ticket and add_support_ticket_message take. Errors: invalid_argument, support_unavailable.

Argumento	Tipo	Descripción
`title` requerido	`string`	A short summary of the problem.
`description` requerido	`string`	What happened, in detail.

`list_support_tickets` List support tickets

Permiso: issuers:read

List the caller's support tickets, newest first. Read-only; works with no issuer. Returns {tickets: [{id, title, state (open | in_progress | resolved | closed), created_at, updated_at, message_count, last_message_from (user | support | null)}]}. A ticket whose last_message_from is support has an answer to read with get_support_ticket. Error: support_unavailable.

Sin argumentos.

`get_support_ticket` Get support ticket

Permiso: issuers:read

Returns {ticket: {id, title, description, state (open | in_progress | resolved | closed), created_at, updated_at, messages: [{from (user | support), text, at}]}}. Errors: invalid_argument, not_found (no such ticket of the caller's), support_unavailable.

`add_support_ticket_message` Add support ticket message

Permiso: issuers:write

Add the caller's reply to one of their support tickets: an answer to support's question or more details. Works with no issuer. Support staff read the message; support never needs CSD files, key passwords or tokens. Returns {ticket} with the whole conversation, as get_support_ticket. Errors: invalid_argument, not_found, ticket_closed (a closed ticket takes no replies; create_support_ticket opens a new one), support_unavailable.

Facturación

Borradores, timbrado, cancelación, receptores y saldo.

`create_invoice_draft` Crear borrador de factura

Permiso: invoices:write

Create a CFDI draft for the calling issuer from a whole CFDI document (the Comprobante JSON object). The document is validated and stored as given; the result is the stored invoice in the get_cfdi shape, with version 1. A type I draft may omit Receptor (a receiver can fill it in through request_receiver_data), but it is required to sign. Returns a needs_csd status instead of a draft if the issuer has no CSD.

Argumento	Tipo	Descripción
`cfdi` requerido	`object`	The CFDI 4.0 Comprobante document.
`issuer` requerido	`string`	Id of the issuer the call acts for, from list_issuers.

  },
  "required": [
    "cfdi",
    "issuer"
  ]
}

`draft_cfdi` Draft CFDI

Permiso: invoices:write

Create a CFDI draft for the calling issuer as a copy of a template: the template's cfdi is copied in, and its note is recorded on the draft, so get_cfdi shows what the draft still needs. template_id is a global template or one of the issuer's own, from list_cfdi_template; another issuer's template is not_found. The draft is validated and stored like create_invoice_draft, with version 1. Returns a needs_csd status instead of a draft if the issuer has no CSD.

Argumento	Tipo	Descripción
`template_id` requerido	`string`	Id of the template, from list_cfdi_template.
`issuer` requerido	`string`	Id of the issuer the call acts for, from list_issuers.

    }
  },
  "required": [
    "template_id",
    "issuer"
  ]
}

`replace_cfdi` Replace CFDI

Permiso: invoices:write

Replace the whole CFDI document of a draft: cfdi is the complete new Comprobante, and nothing of the old one is kept. expected_version is the draft's revision counter (the version field of get_cfdi, which starts at 1 and goes up on every change), not the CFDI Version attribute (4.0). A stale expected_version answers a conflict with the current version. Drafts only: a signed or canceled CFDI answers invalid_state, and so does a draft with an open receiver request (revoke_receiver_request closes it). Returns the stored CFDI in the get_cfdi shape with the new version.

Argumento	Tipo	Descripción
`invoice_id` requerido	`string`
`expected_version` requerido	`integer`	The draft's version from get_cfdi (starts at 1), not the CFDI Version attribute.

`patch_cfdi` Patch CFDI

Permiso: invoices:write

Apply an RFC 6902 JSON Patch to a draft's CFDI document. patch is an array of at most 100 operations (add, remove, replace, move, copy, test), applied in order to a copy of the stored CFDI. Paths are JSON Pointers from the CFDI root, for example /Conceptos/0/Cantidad. expected_version is the draft's revision counter (the version field of get_cfdi, which starts at 1 and goes up on every change), not the CFDI Version attribute (4.0). A stale expected_version answers a conflict with the current version. A patch that does not apply (a missing path, an unknown operation, a failed test, or more than 100 operations) answers invalid_argument with op_index, path and reason, and nothing is written. Drafts only: a signed or canceled CFDI answers invalid_state, and so does a draft with an open receiver request (revoke_receiver_request closes it). Returns the stored CFDI in the get_cfdi shape with the new version.

Argumento	Tipo	Descripción
`invoice_id` requerido	`string`
`expected_version` requerido	`integer`	The draft's version from get_cfdi (starts at 1), not the CFDI Version attribute.
`patch` requerido	`object[]`	RFC 6902 operations, applied in order. add, replace and test take a value; move and copy take a from.

`sign_cfdi` Firmar factura

Permiso: invoices:write

Stamp (timbrar) a draft invoice through the PAC. When billing is on this debits the stamp price from the caller's credit first (see get_account_credit): a credit that does not cover it answers insufficient_balance and nothing is stamped; a failed stamp is credited back. The deployment, not an argument, decides whether stamps are real CFDIs or PAC test stamps, except that an issuer using a SAT test CSD or a document addressed to a SAT test RFC is stamped in the sandbox: no credit is charged and no balance is needed. Every successful result reports which in ambiente ("produccion" or "prueba"); get_cfdi and list_cfdi carry the same ambiente for signed invoices. expected_version is the version last read; a stale version answers a conflict with the current version. A type I draft without a Receptor cannot be signed (invalid_argument, receptor_missing). A Fecha more than 72 hours old is replaced by the current Mexico City time. The stored amounts are signed exactly as saved. Drafts only, invoices and payment complements alike (signing a complement locks the paid PPD invoices and revalidates their balance: a stale one answers invalid_argument with payment_balance). Returns the signed invoice in the get_cfdi shape (timbre.uuid and timbre.fecha_timbrado set), including downloads (permanent XML and PDF links, see get_cfdi), plus ambiente, or a needs_csd status if the issuer has no CSD.

`create_payment_complement_draft` Crear borrador de complemento de pago

Permiso: invoices:write

Build a draft payment complement (comprobante type P, Pagos 2.0) that records payments received for one or more PPD invoices, without writing the document by hand. Arguments: fecha (the complement's own Fecha, YYYY-MM-DDTHH:MM:SS, required: the server never picks the clock) and pagos, an array of {fecha_pago, forma_de_pago (SAT c_FormaPago key, never 99), num_operacion (optional), documentos: [{invoice_id (the id of a signed PPD invoice of yours), imp_pagado (decimal string)}]}. The server takes Receptor from the paid invoices (they must share one receptor), numbers each installment from its ledger and computes the balances and taxes; the result is the stored draft in the get_cfdi shape, an ordinary draft that replace_cfdi replaces and sign_cfdi stamps. Validation problems (an invoice that is a draft, canceled, PUE or unknown, an amount above the balance, ...) answer invalid_argument with the per-field errors. Returns a needs_csd status instead of a draft if the issuer has no CSD.

`create_credit_note_draft` Crear borrador de nota de crédito

Permiso: invoices:write

Build a draft credit note (nota de crédito, comprobante type E with CfdiRelacionados TipoRelacion 01) that reduces or reverses an invoice, without writing the document by hand. The invoice is named by exactly one of invoice_id (the id of one of your signed invoices, PUE or PPD; a draft, canceled or non-invoice document is refused) or folio_fiscal (its UUID; also valid for an invoice issued elsewhere). For your own invoice the server takes Receptor and, when conceptos is omitted, the concepts from it (a full credit); for an invoice issued elsewhere receptor ({Rfc, Nombre, DomicilioFiscalReceptor, RegimenFiscalReceptor, UsoCFDI?}) and conceptos are required, and nothing about that invoice is checked here. Other arguments: fecha (the note's own Fecha, YYYY-MM-DDTHH:MM:SS, required: the server never picks the clock), forma_pago (SAT c_FormaPago key, never 99: the note is PUE), uso_cfdi (default G02) and conceptos, the concepts to credit in the same shape as the document's Conceptos (ClaveProdServ, Cantidad, ClaveUnidad, Descripcion, ValorUnitario, ObjetoImp, Impuestos). moneda (SAT c_Moneda key) and tipo_cambio (required for a currency other than MXN) default to your invoice's own, or MXN for one issued elsewhere. informacion_global ({Periodicidad, Meses, Año}) is required exactly when the receptor is XAXX010101000 (público en general); for your own invoice it is copied from it when omitted. The server computes every amount and tax; the result is the stored draft in the get_cfdi shape, an ordinary draft that replace_cfdi replaces and sign_cfdi stamps. The total credited across one of your invoices' signed notes cannot exceed its Total (credit_exceeds_total says what is left). Validation problems answer invalid_argument with the per-field errors. Returns a needs_csd status instead of a draft if the issuer has no CSD. An invoice with signed credit notes cannot be canceled until they are.

`get_invoice_balance` Consultar saldo de factura

Permiso: invoices:read

The payment balance of one signed PPD invoice (MetodoPago PPD): total, pagado, saldo, next_parcialidad, payable (false when saldo is 0.00) and the installments already applied by signed payment complements. Read-only. For a payment complement written by hand, uuid, next_parcialidad and saldo are the values of IdDocumento, NumParcialidad and ImpSaldoAnt. A draft (no folio fiscal yet), a canceled invoice, a PUE invoice or a payment complement answers invalid_state with the reason.

`get_account_credit` Consultar saldo de la cuenta

Permiso: invoices:read

Get the caller's prepaid stamp credit (the account balance used to pay for stamping) and the price of one stamp. Read-only. This is not the outstanding balance of an invoice (that is get_invoice_balance). Every sign_cfdi debits the stamp price from this credit (invoices, credit notes and payment complements alike); when it does not cover it sign_cfdi answers insufficient_balance and nothing is stamped. Returns {billing: on, balance, currency, stamp_price, stamp_currency, stamps_affordable (null if the credit is kept in another currency than the price)} or {billing: off} when stamps are free. create_account_topup_link adds credit.

`list_account_credit_history` Listar historial de saldo

Permiso: invoices:read

List the caller's stamp-credit history, newest first: the top-ups that added credit and the stamps that used it. Read-only. This concerns the account's prepaid credit only, not CFDIs (those are in list_cfdi) and not payments received for an invoice. Returns {billing: on, total, limit, offset, entries: [{when (ISO 8601 UTC or null), kind (topup | bonus | welcome_bonus | referral_bonus | promotion | stamp | stamp_refund | adjustment), amount (signed: stamps are negative), currency, cfdi_id (the stamped document, for stamp rows, else null)}]} or {billing: off}.

`create_account_topup_link` Crear enlace de recarga

Permiso: invoices:write

Create a payment link that adds credit to the caller's stamp-credit balance (see get_account_credit). Nothing is charged by this call: it only returns a link the user opens in their browser to pay with the payment provider. This is not a CFDI payment complement and has nothing to do with invoices. Every top-up is invoiced (a CFDI is issued to the customer once the payment is confirmed), so invoice_to says to whom: the RFC of one of the caller's issuers (list_issuers); the CFDI uses the fiscal data on that issuer's profile. It is required where top-ups are invoiced and ignored elsewhere; a user with no issuer must first register a razón social in the web app. Returns {billing: on, amount, payment_url, message} (the payment is made by opening payment_url in a browser; the credit arrives once the provider confirms the payment) or {billing: off}. Errors: invalid_argument (invoice_to missing, unknown or not the caller's), topup_unavailable (the deployment has no top-up product), topup_failed (the provider refused; the message says why).

Argumento	Tipo	Descripción
`amount` requerido	`number`	Amount to add, in the product's currency, up to two decimals.
`invoice_to` requerido	`string`	Who the top-up is invoiced to: the RFC of one of the caller's issuers.

Return everything stored about one invoice of the calling issuer: its version, the whole CFDI document (cfdi), and the stamp and cancellation data, which are null until the invoice is signed / canceled, and receiver_request: null, or the state of its receiver request link (status open, stamped, expired or revoked, failed_attempts and last_error, never the url). Also carries direction (issued or received) and origin (cefidia or sat), and template_id and template_note, which are the template a draft was made from and its note, null for any other invoice; the id is explicit, so a received CFDI is found by its id whatever list_cfdi' direction default is. Also carries downloads: null for a draft, otherwise {xml, pdf}, the links to download the stamped XML and PDF, each {filename, content_type, size_bytes, download_url} or {error} when its file cannot be checked or rendered. Open a link in a browser to save the file; the file never passes through this tool. A PDF not generated yet is generated once, here, before its link is returned. The links never expire, are the same on every call and show the CFDI's current state (a canceled one has its PDF marked as canceled). Anyone who holds a link can download the file, so it can be given to the receiver; do not post it anywhere public.

`request_receiver_data` Pedir datos al receptor

Permiso: invoices:write

Create the link a receiver uses to fill in their own fiscal data for a draft type I invoice, so the issuer does not collect it. The receiver opens the link, reviews the invoice, enters their RFC, name, postal code, tax regime and CFDI use (and optionally email and phone), and the invoice is stamped automatically; the same link then offers the PDF and XML downloads, and the receiver is saved in your receiver directory (list_receivers). The draft has no Receptor and is otherwise valid. expected_version is the version last read. The result's url is returned only once and Cefidia does not send it to the receiver. Anyone who has the url can enter the receiver data and trigger the stamp, which is charged to the caller's credit (see get_account_credit); revoke_receiver_request turns it off. While the link is open the draft cannot be updated or deleted; sign_cfdi still works. One open link per invoice: requesting again answers already_requested until the link is revoked. Returns a needs_csd status if the issuer has no CSD.

Paths are JSON Pointers from the CFDI root, for example /Conceptos/0/Cantidad. At least one of patch, name and note is required. The save checks run on the result: TipoDeComprobante must stay I, E or P, a blank note is refused, and the cfdi may not contain Version, Emisor, LugarExpedicion or Fecha. A patch that does not apply (a missing path, an unknown operation, a failed test, or more than 100 operations) answers invalid_argument with op_index, path and reason. Nothing is written on any failure. A global template is invalid_state, since global templates are read-only. Drafts made from the template are not changed. The result is the template.

`name` requerido	`string`
`unit_price` requerido	`string`	Decimal string, e.g. '199.00'
