Factuarea is an invoicing and management platform for businesses and freelancers in Spain. This is its official Model Context Protocol server — the same service the Factuarea team runs in production, not a wrapper built on top of it. Whatever you can do in the Factuarea dashboard or through its REST API, your agent can do in conversation: from issuing a VeriFactu invoice to checking who clocked in this morning.

Connect

The server lives at https://mcp.factuarea.com. Add it to your client and sign in with your Factuarea account — no installation, no key to copy. On the consent screen you pick the company, the environment (live or test) and exactly which permissions to grant.

MCP access is included in every Factuarea plan, also during the trial.

Ask it things like

"Invoice Talleres Ruiz for yesterday's delivery note and email it to them."

"Which invoices from this quarter are still unpaid? Send each customer a reminder."

"Turn quote 2026-014 into an invoice, but move the due date to the 30th."

"Register this supplier invoice and mark it as paid by bank transfer."

"Raise every price in the wholesale price list by 5 %."

"Prepare the Modelo 303 workbook for the third quarter."

"Why didn't WooCommerce order #1042 produce an invoice?"

"Who on the team hasn't clocked in today?"

What it covers

Every tool, its domain and the permission it needs: docs.factuarea.com/mcp/tools.

Alongside the tools, the server publishes 9 fiscal guides as resources (factuarea://guardrails/…: issuing, voiding versus rectifying, invoice types, lines and amounts, VAT regime keys, series, buyer identification, VeriFactu prerequisites, multiple companies) and 5 guided workflows as prompts: issuing an invoice, fixing a failed one, registering a customer by tax ID, connecting an online store and tracing an order that was never invoiced.
