Overview

Description from the maker (original English)

Read invoices, clients and products in Fakturowo; create documents and update payment status.

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.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Online shops & payments

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 9 things (tools) fakturowo_list_documents, fakturowo_get_document, fakturowo_get_next_document_number, fakturowo_list_clients …
  • 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.

  • fakturowo_list_documents

    List invoices and other documents on the account, 100 per page: id (api_numer), type, number, issue and sale date, currency, net/VAT/gross value, seller and buyer, payment status, due date and KSeF number. Filter by document type or by seller/buyer tax number. Values are the vend

  • fakturowo_get_document

    One document by its id (api_numer, from fakturowo_list_documents or the id returned when it was created): the header fields and every line item (name, unit, quantity, net/gross price, discount, VAT rate and amount, gross value). Fakturowo api_zadanie=3 with api_numer.

  • fakturowo_get_next_document_number

    The running number Fakturowo will give the next document of a type (the sequence counter saved on the account). Nothing is created. Fakturowo api_zadanie=8.

  • fakturowo_list_clients

    List the saved clients (contractors), 100 per page: id (api_numer), name, address, tax number, contact details, account number and notes. PESEL and ID-card numbers are never returned. Fakturowo api_zadanie=4.

  • fakturowo_get_client

    One saved client by id (api_numer, from fakturowo_list_clients). PESEL and ID-card numbers are never returned. Fakturowo api_zadanie=4 with api_numer.

  • fakturowo_list_products

    List the saved products and services (the catalogue used on documents), 100 per page: id (api_numer), name, unit, VAT rate, net price, gross value, currency, comment, GTU code and discount. Fakturowo api_zadanie=6.

  • fakturowo_get_product

    One saved product by id (api_numer, from fakturowo_list_products). Fakturowo api_zadanie=6 with api_numer.

  • fakturowo_create_document

    WRITE: issue a new document (invoice, proforma, receipt...) on the account. It is saved immediately and takes the next number in its sequence; this tool cannot delete it again, and calling it twice issues two documents. Issue documents one at a time and wait for each reply: Faktu

  • fakturowo_set_document_payment_status

    WRITE: change the payment status of an existing document (unpaid, paid, partially_paid) and optionally the amount already paid. Only those fields are sent; Fakturowo edits the document in place. Fakturowo api_zadanie=1 with api_numer.

Common questions

Is Fakturowo 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 (1.10.4) reached the registry today.

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: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

Fakturowo MCP by usefulapi

Live endpoint: https://fakturowo.usefulapi.io/mcp

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://fakturowo.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http fakturowo https://fakturowo.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": { "fakturowo": { "url": "https://fakturowo.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 Fakturowo credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/fakturowo/

Connect with your Fakturowo API key from Konto and, if needed, the account-specific API URL shown there. API access requires the vendor’s paid add-on. Issuing a document creates it immediately; payment changes affect the saved document. Regenerating the API key creates a new usefulapi billing identity.
