Works in the Codex app (web and desktop) and via the Codex CLI. No config file needed if you use the app.

Step 1: Add the MCP server in the Codex app

Open Codex and go to Settings (gear icon) → MCP servers
Click Add server and pick Streamable HTTP as the transport (the Codex app sometimes calls this "streamable MCP")
Enter:
- • Name: Praat met je Boekhouding
- • URL: copy the URL below
Click Save. Codex then starts the OAuth login with Exact Online automatically (click Authenticate if prompted)

MCP Server URL:

You'll log in via OAuth - no API key and no config file needed

First time? After saving, Codex opens an Exact Online login screen, or shows a separate "Authenticate" button next to the server. Log in and the connector works immediately. You only need to do this once.

Alternative: Codex CLI

Working from the command line? Add the server, then log in separately:

codex mcp add exact-online --url "https://api.praatmetjeboekhouding.nl/mcp"
codex mcp login exact-online

The first command adds the server to ~/.codex/config.toml, the second starts the OAuth login with Exact Online. Unlike in the app, this doesn't happen automatically from the CLI.

All platforms connect via OAuth login, no API key needed. An API key for API or headless use is available in your Dashboard.

3Restart your AI Assistant

Completely close and restart your AI assistant. The MCP server will be loaded automatically.

Frequently asked questions

Do I need technical knowledge to connect?

For Claude and ChatGPT, not really — you connect with an API key (starting with exa_) or via OAuth and follow our steps. No code needed. For Gemini and Copilot it's a bit more technical, via the CLI/SDK or Copilot Studio. Unsure? Start with Claude or ChatGPT.

Does it work with ChatGPT?

Yes, and it runs in production. You connect it via Connectors in ChatGPT on the web. On ChatGPT Business, Enterprise and Edu the connection works in full, including creating and changing entries; on Pro you can retrieve data. Then you ask questions in plain language about your Exact administration and get instant answers.

Does it work with Claude?

Yes, and this is the most direct way. Claude supports our connection natively via MCP — in Claude Desktop, Claude Code and Claude on the web. You do need a paid Claude plan. Once connected, you simply talk to your books without installing anything else.

Can I connect multiple administrations?

Yes. How many depends on your plan: Free 2, Starter 3, Pro 10 and Enterprise unlimited. You can also set per administration whether writing is enabled.

How does onboarding work?

Three steps: you create an account, authorize your Exact Online administration and connect your AI assistant via the MCP URL. The connection is active within a few minutes and you can ask your first question right away. No technical knowledge required.
