Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.
vyfakturuj_list_invoicesSearch documents (faktury, zalohove faktury, proformy, objednavky ...); pass sort=date_created~desc for the newest first. Each row has id, number, type, dates, customer, VS, currency, total, flags and flags_decoded (paid, sent_to_customer, cancelled, ...) and the public/PDF URLs;
vyfakturuj_get_invoiceOne document with all fields: supplier and customer blocks, items (text, quantity, unit_price, vat_rate, totals), dates, VS, bank details, total, flags and flags_decoded, payment method, public page, PDF and online-payment URLs. GET /invoice/{id}/.
vyfakturuj_create_invoiceWRITE. Creates a document in Vyfakturuj. Vyfakturuj has NO draft state: the document is issued at once and takes the next number of its number series (delete or cancel it in Vyfakturuj if wrong). Does NOT send an e-mail to the customer, does NOT mark it paid and moves no money; a
vyfakturuj_list_contactsSearch the address book (adresar): id, name, company, ICO (IC), DIC, address, e-mail (mail_to), phone, default days_due. Filter by free text q, ICO, DIC, name, e-mail or phone. Paged with rows_limit/rows_offset. GET /contact/.
vyfakturuj_get_contactOne address-book contact with every field (billing and delivery address, ICO/DIC, e-mails, default texts and days_due). GET /contact/{id}/.
vyfakturuj_create_contactWRITE. Adds a contact to the address book (it is not a customer message: nothing is sent). Give at least a name (the address-book label) or company or last name. Returns the new contact with its id. POST /contact/.
vyfakturuj_get_templateOne template / recurring invoice (sablona, pravidelna faktura) by id: its items, customer, schedule and settings. The API has no list endpoint for templates, so the id comes from the user (the number in the template's URL in Vyfakturuj). GET /template/{id}/.
vyfakturuj_list_payment_methodsThe payment methods of the account (id_payment_method, name, type: 1 bank transfer, 2 cash, 4 cash on delivery, 8 card, ...). Use the id in vyfakturuj_create_invoice. GET /settings/payment-method/.
vyfakturuj_list_number_seriesThe numbering series (ciselne rady) of the account: id_number_series, the document type it is for, name and the number pattern. Use the id in vyfakturuj_create_invoice. GET /settings/number-series/.
vyfakturuj_list_tagsThe tags (stitky) of the account: id_tag, name and colour. Invoices carry an id_tag. GET /settings/tags/.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 4 of 4 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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed yesterday, and the latest version (1.26.1) reached the registry today.
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 on the web (full MCP on Business and above; Pro read-only).
