How to connect Grok Bot to Fortnox
The Nordsynk template gives the bot instructions for working in Fortnox. You make the connection itself with your own Nordsynk account, because a template never carries sign-ins.
Send to the bot
Connect Nordsynk as a custom MCP server at https://mcp.nordsynk.se/mcp. Show the authorization so I can sign in with my own account. Then check the connection by reading company information. Make no changes in Fortnox.

What you need, and what we don't promise
You need
The Grok Bot app on a subscription that includes it, and a Nordsynk seat for your Fortnox user.
The connection stays with you
A shared bot carries its instructions but not custom MCP servers. Whoever adds the template connects their own Nordsynk account and picks their own companies.
Approval in the browser
The bot shows a link to Nordsynk's approval page. We have not verified an approval card inside Grok Bot itself, so we don't promise one.
You control what the bot can reach
You sign in to Nordsynk and choose which companies the bot may use. The bot can only reach what your Fortnox user has permission to and the Fortnox areas the company's access policy allows. Sign-in happens on Nordsynk's own page, so never type a password into the chat.
A preview appears in your browser before every change. Nothing changes in Fortnox until you approve it.

Frequently asked questions about Fortnox and Grok
Can you connect Grok to Fortnox?
Yes. With Nordsynk you add Fortnox as a custom MCP server in Grok Bot and sign in with your Nordsynk account. The bot can then read from, and propose changes in, the Fortnox companies you have chosen.
What is Grok Bot?
Grok Bot is xAI's app for AI assistants that work on their own computer in the cloud. Each bot has a name, a job and its own instructions, and can use connected apps such as Nordsynk.
How do I add Nordsynk to Grok Bot?
Add the Nordsynk template and ask the bot to connect Nordsynk at https://mcp.nordsynk.se/mcp. Open Authorize, sign in to Nordsynk and choose companies. Then ask the bot to read company information to check the connection.
Does Nordsynk work on grok.com?

Can Grok Bot change records in Fortnox?

The price is 199 SEK per Fortnox company per user per month. Each user needs a seat of their own in every company where Nordsynk is used. Your Grok Bot subscription is extra.

No. A shared bot carries its name, instructions and skills, but not custom MCP servers. Whoever adds the bot connects their own Nordsynk account and chooses their own companies.
