Can the AI change data in Fortnox?

Only if you allow it. You set read-only or read-and-change access on the API key. With change access, changes happen in Fortnox right away and can't be undone from the AI side, so check what the AI proposes before you confirm.

Does the AI see my Fortnox password?

No. Your Fortnox connection and its tokens stay with Junipeer. The AI app only gets the results of the requests you allow.

Do I need the Fortnox integration too?

No. Fortnox MCP works on its own. If you already sync Fortnox with Junipeer, you can add it at the same price.

Does it work with my Fortnox plan?

It works with what your Fortnox account and its permissions allow. If you don't have a Fortnox module, the AI can't use that part.

Can I ask in Swedish?

Yes. The AI answers in the language you write in.

What counts as a request?

One call from your AI to Fortnox through Junipeer.

€39/mo plus €2 per 1,000 requests, excl. VAT.

Why use Junipeer's Fortnox MCP instead of setting one up myself?

Open-source Fortnox MCP servers exist, but you host, secure and update them yourself, and handle Fortnox's authentication. Junipeer runs it for you, keeps it updated when the Fortnox API changes, and offers support from a team that has built Fortnox integrations since 2021.

What Fortnox MCP is

Fortnox MCP lets your AI assistant read and work with your Fortnox data. Connect Fortnox to Junipeer once, then add Junipeer as a connector in your AI app. Ask in plain language, and the AI fetches the answer straight from Fortnox.

MCP (Model Context Protocol) is the open standard AI assistants use to connect to other software. Junipeer hosts the connection to Fortnox, so you don't install, code or maintain anything.
