Read SuperFaktura invoices, clients, expenses, bank and stock; create clients, expenses and drafts. Hosted by usefulapi — connect from Claude, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"superfaktura": {
"url": "https://superfaktura.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"superfaktura": {
"type": "http",
"url": "https://superfaktura.usefulapi.io/mcp"
}
}
}Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
The login page asks for your SuperFaktura e-mail (the API user), SuperFaktura API key and Instance.
Optional: Company id.
In SuperFaktura open Tools → API access (Nástroje → API prístup) for the e-mail, API key and company id. API access is only included in the top SuperFaktura plan (the price list shows API as not available on the lower plans), so a lower plan cannot connect. The company id is optional (leave it empty for your default company). Pick the instance you log in to (SK, CZ or AT). A dedicated user with the Administrator role is recommended. SuperFaktura allows 1000 API requests per day and 31000 per month per account. Your key is used only to call the SuperFaktura API on your behalf; it is never shown to anyone.
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: the login page asks for your SuperFaktura e-mail (the API user), SuperFaktura API key and Instance. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
| Tool | Type | What it does |
|---|---|---|
superfaktura_get_company | read | Get the company profile and API limits The company the API key is working in (name, IČO, DIČ, IČ DPH, address, VAT-payer flag, bank accounts) and the remaining API quota (SuperFaktura's fair-use policy is 1000 requests per day and 31000 per month; every tool call here uses one request). Good first call. With all_companies=true also the other companies the user can access (their ids are the company_id of the login). GET /users/getUserCompaniesData. |
superfaktura_list_invoices | read | List or search invoices List issued documents with client, items, totals and payment status. type selects the document kind (default regular = ordinary invoices; also proforma, estimate = quote, order, cancel = credit note, delivery, draft, reverse_order; several allowed). Without a date filter SuperFaktura returns only the CURRENT YEAR; use created_period='all' or a date range for older ones. status: issued, partially_paid, paid, overdue. search matches client name, number, VS ... Paged: pass next_page as page. GET /invoices/index.json. |
superfaktura_get_invoice | read | Get an invoice One document (invoice, proforma, quote ...) with its header (number, dates, status, amounts, currency, symbols, comments), client, items, VAT summary, payments and related documents.

superfaktura_get_response_by_checksum | read | Recover the reply of a create by its checksum If a superfaktura_create_invoice call timed out, fetch the reply of the ORIGINAL request by the checksum it was sent with (kept 3 months), so the document is not created twice. GET /api_logs/getResponseByChecksum/{checksum}. |
superfaktura_create_client | write | Create a client WRITE: adds a new client to the SuperFaktura address book (only the name is required). Nothing is sent to the client. Not idempotent: calling twice creates two clients, so check superfaktura_list_clients first. POST /clients/create. |
superfaktura_add_contact_person | write | Add a contact person to a client WRITE: adds a contact person (name and e-mail, optional phone) to an existing client. Nothing is sent to that person. Not idempotent. POST /contact_people/add/api:1. |

superfaktura_create_expense | write | Record a received expense WRITE: records a received document (expense) with ONE total amount and VAT rate, e.g. a supplier invoice or a bill. It is created unpaid: no payment is recorded and nothing is sent. No attachments. Not idempotent: calling twice records two expenses. POST /expenses/add. |
superfaktura_create_invoice | write | Create an unsent invoice document WRITE: creates ONE document in SuperFaktura for the user to review: type draft (concept, default), estimate (quote), order or proforma. A final regular invoice cannot be created here. It is NOT sent (no e-mail, no post), NOT marked paid or sent, and has no payment link or discount. Give an existing client_id (its name is read first with one extra GET /clients/view/{id}, so the call uses 2 requests of the daily quota) OR a new client's name (+ optional ico/dic/ic_dph/address...). Items: name, unit price without VAT, VAT rate, quantity. Not idempotent: pass a checksum (max 32 chars) so a timed-out call can be recovered with superfaktura_get_response_by_checksum instead of retried. POST /invoices/create. |
superfaktura_usage_status | Usage status (free-tier meter) Report the caller's current free-tier usage this month: calls used, monthly limit, remaining, and whether the cap is reached. Read-only; does not count against the meter. | |
superfaktura_request_feature | Request a missing feature Tell usefulapi that the user needs something the SuperFaktura tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
superfaktura_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED SuperFaktura tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Does not count against the meter. | |
superfaktura_cancel_subscription | Cancel the Pro subscription Cancel the caller's SuperFaktura Pro subscription at the end of the paid period (no refund for the current period; unlimited calls continue until then, then the free tier applies). Requires confirm: true. Run superfaktura_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 100 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited |
Pro covers this SuperFaktura server only. Subscribe with superfaktura_upgrade (it returns a Stripe Checkout link). Cancel any time with superfaktura_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running superfaktura_upgrade before then undoes the cancel. Or write to [email protected].
No. usefulapi is an independent service. It is not affiliated with or endorsed by SuperFaktura. The server calls the SuperFaktura API with your own SuperFaktura access, so it sees only the data that your account can see.
The login page asks for your SuperFaktura e-mail (the API user), SuperFaktura API key and Instance. See Before you connect for where to find them.
No. 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: the login page asks for your SuperFaktura e-mail (the API user), SuperFaktura API key and Instance. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the SuperFaktura API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in SuperFaktura.
Yes, if you approve it. 5 of the 25 SuperFaktura tools can create or change data. The other 20 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this SuperFaktura server only. Run superfaktura_usage_status to see how many calls you used.
Ask the AI to run superfaktura_upgrade: it returns a Stripe Checkout link. To cancel, run superfaktura_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with superfaktura_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
