Overview

AI-generated overview

Connects an assistant to a Fakturowo invoicing account to read invoices, clients and products, issue documents and update payment status.

What you can do
  • List and fetch invoices and other documents, with line items, values, payment status and KSeF number
  • List and fetch saved clients (contractors) and the product/service catalogue
  • Look up the next running document number for a document type
  • Issue a new document (invoice, proforma, receipt) on the account
  • Change a document's payment status and optionally the amount paid
  • Check monthly tool-call usage, request a feature, upgrade or cancel a plan
When to use it
Useful when you keep invoices in Fakturowo and want an assistant to answer questions about documents, clients or products, or to issue invoices and mark them paid from a chat instead of the web panel.
Requirements
Remote MCP endpoint; no local runtime. Sign-in is via OAuth, where the login page asks for your Fakturowo credentials; the README says not to add an Authorization header or API key to the client config. Fakturowo API access requires the vendor's paid add-on. A free tier allows 50 tool calls per month; paid plans are billed through Stripe.
Before you install
Two tools write to the live account: creating a document saves it immediately, takes the next number and cannot be deleted by this server, and calling it twice issues two documents; payment-status changes edit the saved document. Confirm before any write. Usage is metered and paid plans cost money; regenerating the Fakturowo API key creates a new billing identity. Client records never return PESEL or ID-card numbers.

Installation

In SourceWeft

  1. Open Fakturowo MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Ffakturowo/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

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:
json
{  "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.

fakturowo_list_documents

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 vendor's own (dates DD-MM-YYYY; dokument_rodzaj is the type code with a readable name for common types).

Parameterspagebuyer_tax_iddocument_typeseller_tax_id

fakturowo_get_document

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.

Parametersdocument_idrequired

fakturowo_get_next_document_number

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.

Parametersdocument_type

fakturowo_list_clients

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.

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.

Parameterspage

fakturowo_get_product

Get product

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

Parametersproduct_idrequired

fakturowo_create_document

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: Fakturowo says overlapping saves can get the same number when the account's numbering check is off. Needs a buyer and at least one line item; the seller defaults to what the account has saved only if Fakturowo allows that, otherwise pass seller. Returns the new document's id (api_numer); with public_links true also a public PDF and preview link (anyone with the link can open the document). Fakturowo api_zadanie=1.

Parametersbuyerrequireditemsrequirednotesplacesellercurrencysale_dateissue_datepaid_amountpayment_typepublic_linksdocument_type+1 more

fakturowo_set_document_payment_status

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.
