Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Read Oblio clients, products and documents; create proformas, issue, collect and cancel invoices.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

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.
oblio_list_companiesThe companies (CIF, name, your access level) linked to the connected Oblio account. Good first call: every other tool needs a CIF from here. GET /api/nomenclature/companies.
oblio_list_vat_ratesVAT rates (name, percent, default) of a company; use the name and percent on document lines. GET /api/nomenclature/vat_rates.
oblio_list_seriesDocument series of a company (type Factura/Proforma/Aviz, name, start, next number, default). Use the name as series_name. GET /api/nomenclature/series.
oblio_list_languagesForeign languages a company can issue documents in (code, name). GET /api/nomenclature/languages.
oblio_list_managementStock managements (gestiuni) of a company with their work point and type; works only when stock is enabled. GET /api/nomenclature/management.
oblio_list_clientsClients of a company, optionally filtered by name or client CIF. Up to 250 per page: pass next_offset as offset for the next page. GET /api/nomenclature/clients.
oblio_list_productsProducts and services of a company with unit, price, VAT and (with stock) quantities. Up to 250 per page: pass next_offset as offset. GET /api/nomenclature/products.
oblio_get_documentOne invoice, proforma or notice by series and number: type, series, number, link to the PDF and (invoices) the collections. GET /api/docs/ .
oblio_list_invoicesInvoices of a company with filters (series, number, dates, client, draft/canceled/collected), newest first by default. Optional products, collections and e-Factura (SPV) status per invoice. Pass next_offset as offset for the next page. GET /api/docs/invoice/list.
oblio_list_webhooksThe webhook subscriptions of the account (id, CIF, topic, endpoint). GET /api/webhooks.
oblio_create_proformaCreate a PROFORMA (not a fiscal invoice; the preferred first step). It takes the next number of the series immediately, there is no draft state, and Oblio sends no e-mail. Check client, lines, VAT (oblio_list_vat_rates) and series (oblio_list_series) first. Returns the series, nu
oblio_issue_invoiceISSUE a real INVOICE. This is a legal fiscal document: it takes the next number in the series at once, there is no draft state, it cannot be edited, and it can only be cancelled afterwards (it may also be sent to ANAF e-Factura / SPV, automatically if the account is set up so). N
oblio_collect_invoiceRecord that an issued invoice was paid (receipt, bank order, card...). Changes the invoice's paid status and is not reversible from the API. Needs confirm: true and the user's approval of the amount. Not retried. PUT /api/docs/invoice/collect.
oblio_cancel_documentCANCEL an invoice, proforma or notice. A cancelled invoice stays in the series but is void; if it was already sent to e-Factura / SPV, check the SPV side as well. Needs confirm: true and the user's approval. Not retried. PUT /api/docs/ /cancel.
oblio_restore_documentRestore a previously CANCELLED invoice, proforma or notice. Needs confirm: true and the user's approval. Not retried. PUT /api/docs/ /restore.
oblio_send_einvoice_to_spvSEND an issued invoice to ANAF e-Factura (SPV). Irreversible: a document accepted by ANAF cannot be withdrawn from this API. Needs confirm: true and the user's approval. Not retried: check the status with oblio_list_invoices (with_einvoice_status) before repeating. Returns text,
oblio_create_webhookSubscribe an HTTPS endpoint to an Oblio event (stock changes, drafts/updates/cancellations of documents, collections). Oblio will POST account data to that URL, so only use an endpoint the user named and controls; it must answer 200 with the base64 of the X-Oblio-Request-Id heade
oblio_delete_webhookDelete a webhook subscription by id (from oblio_list_webhooks). Needs confirm: true. DELETE /api/webhooks/{id}.

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 (1.22.3) reached the registry yesterday.

Use Oblio from Claude, Cursor, or any MCP client — companies, VAT rates, series, clients, products, stock, invoices with e-Factura (SPV) status and webhooks, plus creating proformas, issuing, collecting, cancelling and restoring invoices and sending them to SPV (each fiscal write needs an explicit confirmation). Hosted, no local install: connect with your own Oblio credentials.

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 Oblio credentials.
