How it works
Lucanto runs an MCP server — Model Context Protocol, the open standard behind AI-agent integrations. It uses the same personal access tokens and permission scopes as Lucanto's REST API, so connecting an assistant is just another way to use access you already have. Claude Desktop has a ready-made setup guide; ChatGPT and Cursor are also compatible.

Frequently asked questions about AI agents
What is MCP?
MCP (Model Context Protocol) is an open standard that lets AI assistants like Claude and ChatGPT securely connect to apps like Lucanto. Once connected, you can ask your assistant to create invoices, check payment status, or manage clients — in plain language, without opening Lucanto yourself.
Is this available on my plan?
Yes — MCP access is included on every Lucanto plan, including Free. There's no extra cost and nothing to upgrade.
Which AI assistants work with Lucanto?
Claude Desktop has a ready-to-paste config in the documentation. ChatGPT and Cursor speak the same protocol and connect to the same endpoint with the same token, so they work too — we just haven't written the step-by-step for them yet.
Is my data safe?
Your AI assistant connects using a personal access token scoped to read, write, or manage permissions — the same access model as Lucanto's REST API. You choose what it can see and do, and you can revoke access at any time.
Do you have a CLI?
Not yet. MCP is how Lucanto connects to AI agents today; a command-line tool may follow.
How do I set it up?
Generate a personal access token from Settings → API, then add it to your AI assistant's configuration. Full step-by-step instructions, including a ready-to-paste Claude Desktop config, are in the documentation.
