# Introduction

> Connect your Klark business to AI through the MCP protocol

## What is Klark MCP?

Klark MCP is a [Model Context Protocol](https://modelcontextprotocol.io) server that lets your AI assistants (Claude, Cursor, etc.) interact directly with your Klark account.

In practice, your AI can:

* **Create and manage your invoices** — PDF generation, e-invoicing delivery
* **Manage your clients** — create, update, look up
* **Run your product catalog** — references, prices, stock
* **Track your prospecting** — pipeline, scoring, conversion
* **Generate documents** — from your custom templates
* **Process your purchase orders and delivery notes** — OCR, tracking, invoicing
* **Take payments at the register (Kaisse)** — sessions, carts, checkout
* **Manage your calendar (Kalendar)** — appointments and booking links
* **Check your bank accounts** — balances and transactions

## How does it work?

<Steps>
  <Step title="Add the MCP server">
    Configure your AI client (Claude Desktop, Cursor, etc.) with the Klark MCP server URL.
  </Step>

  <Step title="Authenticate">
    On first connection, an OAuth window opens in your browser. Sign in with your Klark credentials.
  </Step>

  <Step title="Use your tools">
    Ask your AI to create invoices, list your clients, follow up on your prospects — everything is accessible through natural language.
  </Step>
