Fortnox tools for your AI agents
16 tools are ready to call through Elaichi's MCP endpoint the moment you connect Fortnox, governed by the same roles, restrictions, and audit log as everything else in Elaichi.
No tools match your search.
Questions, answered
How do I connect Fortnox to Claude?
Connect Fortnox in Elaichi first. Fortnox requires an app registered inside your own Fortnox account, so one person brings that client ID and secret once and then signs in to Fortnox to approve access, and nobody has to repeat that step afterwards. Then open Claude, go to Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp. Fortnox then appears in Claude for you.
Does Fortnox work with ChatGPT and Cursor as well as Claude?
Yes. Once Fortnox is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, Microsoft Copilot, any other MCP client and the Elaichi Agent. You connect Fortnox once and every client gets it.
What can an AI agent actually do with my Fortnox data?
With Fortnox connected, an agent can look up customers, articles and suppliers, read invoices, create a new invoice, and add or update a customer. It can also read your Fortnox company information. It cannot delete anything in Fortnox and it cannot change an invoice once it exists, because this connector does not offer those actions.
Does connecting Fortnox give the AI access to everything in my accounts?
No. Every call runs inside the Fortnox access of the person who signed in, so the agent sees exactly the customers, invoices and suppliers that person can already see in Fortnox. Elaichi can narrow that further, for example to reading only, but it can never widen what Fortnox itself allows.
Can I stop an agent from changing things in Fortnox?
Yes. Restrictions on a Fortnox connection work per action, so you can allow reading customers and invoices while restricting the creation of invoices or changes to customer records. A restricted action still appears in Elaichi's tool search, flagged as restricted, but Claude, ChatGPT, Cursor or Microsoft Copilot cannot run it, whatever the prompt says.
What happens to a Fortnox connection when someone leaves?
Offboarding a person in Elaichi ends their Fortnox access at once, in every client. If they had shared a Fortnox connection, it keeps working for everyone else on the team. Disconnecting Fortnox once in Elaichi removes it from Claude, ChatGPT, Cursor, Microsoft Copilot and every other client together.
Does the Fortnox MCP connector work with Gemini, Codex, Claude Code or other MCP clients?
Yes. Fortnox is reached over the same MCP endpoint every client uses, so anything that speaks MCP can call it — Gemini, Codex, Claude Code, Windsurf, Cline, Zed and OpenCode among them — alongside Claude, ChatGPT, Cursor, Microsoft Copilot, and the Elaichi Agent. The tools on offer and the access behind them are identical whichever client asks. Only the setup screen differs.
Is Elaichi an alternative to Zapier MCP for Fortnox?
Yes. Both let Claude, ChatGPT or Cursor use Fortnox. Zapier MCP fits a team that already automates in Zapier, since each person signs in and acts as themselves in that account. Elaichi fits when IT wants one address for the whole company, per-tool rules by role, and a record of every Fortnox call.
How is Elaichi different from Composio for Fortnox?
Composio gives AI agents tools and sign-in handling across 1,000+ apps, for developers building agents or people using an assistant, billed per tool call. Elaichi gives a company's own people governed access to Fortnox: one address, restrictions per role or user, and $15 per user per month. Both have role permissions and a log of every call.
Put Fortnox in front of your team
