Also use it in ChatGPT or Claude
Oblio MCP is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.

Create the connector

- 4
Use it in a chat
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT

Tools · 18
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/<type>.oblio_list_invoicesInvoices of a company with filters (series, number, dates, client, draft/canceled/collected), newest first by default.

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, nuoblio_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). Noblio_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/<type>/cancel.oblio_restore_documentRestore a previously CANCELLED invoice, proforma or notice. Needs confirm: true and the user's approval. Not retried. PUT /api/docs/<type>/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 headeoblio_delete_webhookDelete a webhook subscription by id (from oblio_list_webhooks). Needs confirm: true. DELETE /api/webhooks/{id}.Recent checks
