Overview

Description from the maker (original English)

Read Italian invoices, receipts and SDI notices; validate, prepare and submit agreed drafts.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 24 things (tools) acube_list_invoices, acube_get_invoice, acube_list_invoice_notifications, acube_get_notification …
  • The registry lists no key to fill in.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • acube_list_invoices

    Sent and received Italian e-invoices (SDI) of the account: uuid, invoice number and date, document type (TD01...), sender and recipient, amounts, marking and notification status. Filter by date, number, document type, party name or VAT number. GET /invoices.

  • acube_get_invoice

    One invoice by uuid: metadata plus the FatturaPA JSON payload (parties, lines, VAT, payment), or the XML file sent to the SDI. GET /invoices/{uuid}.

  • acube_list_invoice_notifications

    The SDI notifications of one invoice (delivery receipt RC, rejection NS, outcome NE, failed delivery MC, deadline expiry DT...), with their type, date and status: how you tell whether an invoice was delivered or rejected. GET /invoices/{uuid}/notifications.

  • acube_get_notification

    One SDI notification by uuid, with its payload. GET /notifications/{uuid}.

  • acube_get_invoice_stats

    Counters of invoices and notifications for a year (annual; monthly or daily detail only if A-Cube activated it), for the whole account or one fiscal id. GET /invoices/stats/{year}.

  • acube_list_draft_invoices

    Draft invoices that were created but not yet sent to the SDI. Same filters as acube_list_invoices. GET /invoices/draft.

  • acube_get_draft_invoice

    One draft invoice by uuid, with its FatturaPA JSON content. GET /invoices/draft/{uuid}.

  • acube_validate_invoice

    Checks an invoice against the FatturaPA rules without creating or sending anything; returns the validation result or A-Cube's errors. POST /invoices/validate.

  • acube_create_draft_invoice

    WRITE: saves a new invoice as a DRAFT in A-Cube. Nothing is sent to the SDI until acube_send_draft_invoice. Not idempotent: calling it twice creates two drafts. Validate first with acube_validate_invoice. POST /invoices/draft.

  • acube_send_draft_invoice

    WRITE: accepts a draft and transmits it to the Sistema di Interscambio. This is a legal act: a sent e-invoice cannot be recalled (only corrected with a credit note) and may be billed by A-Cube. Without confirm: true it only returns the draft for review. Show the draft to the user

  • acube_delete_draft_invoice

    WRITE: permanently deletes a draft invoice (a draft only: a sent invoice answers 409). Without confirm: true it only returns the draft. DELETE /invoices/draft/{uuid}.

  • acube_list_receipts

    Electronic commercial receipts (scontrini) with number, date, status, type (sale, void, return) and totals. GET /receipts.

  • acube_get_receipt

    One electronic receipt by uuid: type, status, number, date, total and links to voiding or returned receipts (no line items: use acube_get_receipt_details). GET /receipts/{uuid}.

  • acube_get_receipt_details

    The line items and VAT, discount and taxable totals of one electronic receipt. GET /receipts/{uuid}/details.

  • acube_list_business_registry_configurations

    The businesses (fiscal ids) set up on the account, with which services are on: customer invoices, supplier invoices, receipts, signature, legal storage. GET /business-registry-configurations.

  • acube_get_business_registry_configuration

    One business by fiscal id: name, email, enabled services and its webhook configurations. GET /business-registry-configurations/{fiscalId}.

  • acube_list_webhooks

    The webhooks (events and target URLs) configured on the account. Authentication keys and tokens are never returned. GET /api-configurations.

  • acube_list_numbering_sequences

    The invoice numbering sequences (name, year, last number). GET /numbering-sequences.

  • acube_get_current_numbering_sequence

    The sequence now in use for a sequence name. Its number is the LAST number used: the next invoice gets that number plus one. GET /numbering-sequences/current/{name}.

  • acube_list_jobs

    Background jobs (invoice, report and zip downloads, F24 and daily receipt report downloads) with status ready, started, completed or error. GET /jobs.

  • acube_get_job

    One background job by uuid with its status and result. GET /jobs/{uuid}.

  • acube_verify_fiscal_id

    Checks whether a codice fiscale or partita IVA is valid. GET /verify/fiscal-id/{id}.

  • acube_verify_company

    Basic registry data of an Italian company by VAT number (name, address, status), optionally with the split-payment check. GET /verify/company/{id}.

  • acube_get_recipient_code

    The account's 7-character SDI recipient code (codice destinatario), the address customers put on invoices they send to you. GET /users/me/recipient-code.

Common questions

Is A-Cube MCP by usefulapi safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.7.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, FOGA node

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://acube.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http acube https://acube.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "acube": { "url": "https://acube.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your A-Cube credentials.

Account access and data

Use your licensed A-Cube API account and select sandbox or production. Your production Italy API contract must permit this hosted connection. Customer onboarding, vendor subscriptions and fiscal processing charges remain separate. No vendor app approval or endorsement is claimed.

Your password is sent only for this sign-in and is not stored in the hosted connection. Only the vendor JWT, email, environment, expiry and billing identity are retained encrypted. Vendor tokens last up to24hours; reconnect on expiry or revocation. There is no silent password login or invented refresh endpoint. Disconnect UsefulAPI to stop this connection; an issued JWT may remain valid until A-Cube expires or revokes it. Billing follows the validated account UID, normally across password changes and environments.

Requested fiscal invoices, tax identifiers, receipts and business records reach your connected AI client and LLM provider. Connect only data you are authorized to process there.

Draft creation saves a draft without transmission. Submission and deletion require explicit confirmation; without it, the tools return a preview. Production submission is a legal act and may incur charges. A-Cube's acknowledgement means accepted for transmission, not confirmed SDI delivery: check invoice notifications. After an uncertain result, check A-Cube before repeating. No operation is automatically replayed.

All24tools were checked against current API specifications and local mocks. Synthetic invoice test data matches required fields/types but is not a legally validated invoice. No real customer data, SDI submissions, receipts or charges were tested.
