Description from the maker (original English)

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.
quipu_list_contactsList contacts (clients and suppliers) of the Quipu account. Filter by kind, tax id, country, email or free text.
quipu_get_contactGet one contact by id, with its totals of paid and unpaid incomes and expenses.
quipu_list_invoicesList invoices (issued and received). Filter by kind, period, operation date, payment status or contact. Totals and PDF links are in the attributes.
quipu_get_invoiceGet one invoice by id. Income invoices include download_pdf_url and ephemeral_open_download_pdf_url (a temporary PDF link).
quipu_list_book_entriesList all book entries (invoices, tickets and other accounting entries) in one list. Filter by type, kind, period, dates, payment status or contact.
quipu_list_numbering_seriesList invoice numbering series (prefixes). Use a series id when you create a draft invoice.
quipu_list_accounting_categoriesList accounting categories (chart of accounts groups). Filter by kind, prefix or active state.
quipu_list_accounting_subcategoriesList accounting subcategories, optionally for one accounting category.
quipu_create_contactCreate a contact (client or supplier). WRITE: it adds a record to the Quipu account. A tax id is needed before you invoice the contact.
quipu_update_contactUpdate fields of one contact. WRITE: it changes the record; only the fields you send change.
quipu_create_draft_invoiceCreate a DRAFT income invoice for a contact. WRITE: it adds a draft to Quipu. It sends no issue date or number, so Quipu does not issue or register the invoice; finalize it in the Quipu app.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
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 –, and the latest version (1.5.3) reached the registry yesterday.
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.

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 Quipu credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/quipu/
On first connect you provide your Quipu API client ID and client secret (Quipu → Settings → API) and your account slug (the part after getquipu.com/ in your Quipu URL). The server validates it and stores it per user. No keys go in config files.
