The world of technology is evolving at an incredible pace, and Artificial Intelligence (AI) has moved beyond being just a conversational assistant to becoming a real business tool. At the heart of this transformation is the MCP (Model Context Protocol), an innovative open-source protocol set to change the way you manage your business.

If you use Moloni ON, there is great news: MCP integration is already available. This means you can connect AI assistants (such as Anthropic's Claude) directly to your invoicing ecosystem. Imagine being able to analyse your business data and interact with your invoicing simply by talking to AI in natural language. Here's everything you need to know about this new feature, how it works, and what you can do with it.


Key takeaways

  • AI-powered document creation: You can ask AI to issue invoices, invoice-receipts, quotations and credit notes directly in Moloni ON.
  • Smart catalogue management: Create new products, items and organise your inventory into categories using simple voice or text commands.
  • Advanced analytics: Access detailed Sales Analysis reports covering all your invoicing documents.
  • Current limitations: At this moment, the integration does not support bulk data exports or direct PDF downloads through the AI chat.
  • Free and secure: The service is free, only requires API access to be enabled on your Moloni ON account, and uses secure OAuth authentication with no API keys required.

What is the Model Context Protocol (MCP) and how does it work?

The Model Context Protocol (MCP) is an open-source protocol created by Anthropic. Its main purpose is to solve one of the biggest limitations of traditional AI tools: data isolation.

Without MCP, if you asked an AI "How are my sales this month?", it wouldn't be able to answer because it has no access to your real business data. MCP acts as a secure, bidirectional bridge. It translates your natural language requests into commands that Moloni ON understands, allowing the AI to access your information dynamically, privately and only with your explicit authorisation.


What can you do with AI and MCP in Moloni ON?

The real power of MCP is that it gives your AI assistant direct access to Moloni ON's capabilities. This means the AI doesn't simply observe your screen — it interacts with the system on your behalf while fully respecting all tax regulations established by the Portuguese Tax and Customs Authority (Autoridade Tributária e Aduaneira — AT).


1. Create and issue invoicing documents

The days of filling in lengthy forms are over. Whether you're in a meeting or finishing a project, you simply tell your AI assistant what you need.

Practical example: "Issue an invoice for WebDesign Ltd worth €1,500 + VAT for Marketing consultancy services."

The AI processes your request within seconds, validates the customer details, applies the correct VAT rate and creates the certified document in Moloni ON, complete with the required ATCUD and QR Code. This applies to every supported document type available within the software.


2. Create and organise products and items

If you've received new stock or want to launch a new service, you can update your product catalogue simply by talking to the AI. Just describe the product and ask for it to be added.

Practical example: "Create a new product called 'Wireless Mouse Pro', selling price €35, standard VAT rate, and assign it to the 'Accessories' category."

The AI connects to your inventory through MCP and instantly creates both the product and its category, making everything ready for future invoices.


3. Real-time sales analysis

Beyond operational tasks, the analytical capabilities remain fully available. You can analyse all your invoicing data to better understand your business performance without opening complex reports.

How is your business kept secure?

Giving AI permission to issue documents and manage your product catalogue requires enterprise-grade security. Moloni ON designed this integration according to the highest industry standards.

  • OAuth Authentication: There's no risk of exposing private API keys that could be copied or compromised. During setup, you're redirected to the official Moloni ON authorisation page where you simply click "Authorise". You remain in complete control of access permissions.
  • AT certification remains fully compliant: Every document created or issued by the AI passes through Moloni ON's certified invoicing engine. Legal compliance, SAF-T (PT) reporting and fiscal security remain exactly the same as if the invoice had been created manually.
  • Intelligent automation: Whether you already use custom AI workflows or are planning to create them, Moloni ON's MCP integration acts as the central connector to streamline your entire business ecosystem.
