# Introduction

The **Altoviz MCP Server** lets you connect an AI assistant — such as ChatGPT, Claude, or any other [Model Context Protocol](https://modelcontextprotocol.io) (MCP) client — directly to your Altoviz account.

Once connected, you can simply ask your assistant to do things in plain language:

> _"Create a draft invoice for Acme Corp for 10 hours of consulting at €90."_
>
> _"What was my turnover last month compared to the same month last year?"_
>
> _"Find the customer whose email is j.doe@example.com and list their unpaid invoices."_
>
> _"Export this year's sales invoices to a CSV file."_

The assistant translates your request into the right Altoviz operations and shows you the result — no code, no API calls, no copy-pasting.

## What is MCP?

The Model Context Protocol is an open standard that lets AI assistants securely connect to external tools and data. The Altoviz MCP Server exposes your invoicing data and actions as a set of **tools** the assistant can use on your behalf, working against the same data you see in the [Altoviz web app](https://altoviz.com).

## What you can do

The server covers most of day-to-day Altoviz usage:

- **Invoicing** — create, finalize, send, and download invoices, quotes, and credit notes; mark invoices as paid
- **Contacts** — manage customers, suppliers, contacts, colleagues, and customer families
- **Catalogue** — manage products and product families
- **Expenses** — browse purchase invoices and receipts
- **Statistics** — turnover comparisons, monthly breakdowns, and e-invoicing readiness
- **Exports** — generate Excel/CSV exports of invoices, customers, accounting registers, and more
- **Automation** — register and manage webhooks

See the full [list of tools](mcp/tools) for details.
