Kantax

AI-native accounting

Connect Claude to your books

Kantax speaks MCP — the protocol AI tools use to connect to real systems. Connect once, and you can keep the books by typing instead of clicking through forms.

Getting started

  1. 1Add Kantax to your AI tool using the command or address below.
  2. 2The tool opens Kantax in your browser. Log in as usual.
  3. 3Choose what the program is allowed to do, and approve it.

Pick your tool

No key to copy, no password to paste. You approve the connection in the browser and can revoke it whenever you like.

Claude Code

Run this in your terminal:

claude mcp add --transport http kantax https://kantax.no/api/mcp/v1

Then type /mcp in Claude Code and follow the login.

Claude Desktop

Go to Settings → Connectors → Add custom connector, and paste the address:

https://kantax.no/api/mcp/v1

Claude opens Kantax in your browser to log in and approve.

Codex / Cursor

Add Kantax as an MCP server over HTTP:

{
  "mcpServers": {
    "kantax": {
      "type": "http",
      "url": "https://kantax.no/api/mcp/v1"
    }
  }
}

Restart the tool and the login opens automatically.

Receipts on your own computer

The local bridge is not published yet.

It's coming soon, and will let Claude upload receipts straight from your computer — the files never travel through the conversation, only the file path does. In the meantime you can ask Claude to fetch receipts that are already online, such as a link from an email or a supplier portal. You can also drag files straight into the Kantax inbox.

You decide what it can do

You choose the access level when you approve the connection, and can change it by reconnecting.

Read only

See accounts, reports, receipts and deadlines. Cannot change anything.

Read and draft

Also: upload receipts, book expenses, draft invoices and maintain customers, suppliers and employees.

Full access — coming later

Issuing invoices and filing VAT and payroll reports with Altinn. Those cannot be undone, so each filing gets its own approval step.

Everything an AI assistant does is recorded in the audit log, tagged with the connection that did it. Review and revoke connections under Settings → AI connections.
