Frequently Asked Questions

1. Go to your Dashboard and copy your API key
2. Open the Claude configuration file:
   • Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json
3. Add the MCP server configuration (see Setup page)
4. Restart Claude Desktop (important!)

This means your Exact Online account is not (or no longer) connected. Solutions:

1. Go to Connect and reconnect
2. Check that you selected the correct region (Netherlands, Belgium, etc.)
3. If you have multiple Exact Online accounts, make sure you choose the right one

Check the following:

• The key starts with exa_ - copy the complete key
• There are no extra spaces before or after the key
• The key has not been revoked (check your Dashboard)
• You have restarted Claude Desktop after changing the config

Still not working? Generate a new key via the dashboard.

You can give your API keys a recognizable name:

1. Go to your Dashboard
2. Click on the pencil icon next to the API key you want to rename
3. Enter a new name (e.g., "Claude Desktop" or "Work laptop")
4. Click "Save"

This helps you distinguish between multiple API keys.

Yes! After connecting to Exact Online, all administrations you have access to become available automatically.

• Free plan: 1 active administration
• Pro plan: Up to 5 administrations
• Enterprise: Unlimited

You can ask Claude: "Show my administrations" to see which ones are available.

You can set a default administration so your AI assistant uses it automatically:

1. Go to your Dashboard
2. Scroll to the "Administrations" section
3. Click on the administration you want to set as default
4. The chosen administration will be marked and automatically used for queries

You can always specify a different administration in your question.

Commands are tool calls to the MCP server. Each time your AI assistant fetches data from Exact Online, it counts as 1 command.

Important: One question can use multiple commands. For example:

• "What is my revenue this month?" → 1-2 commands (fetch revenue)
• "Compare revenue from January and February" → 2-3 commands (fetch two periods)
• "Give me a financial overview" → 3-5 commands (fetch multiple datasets)

In your Dashboard you can see how many commands you've used. The number of commands per question depends on the complexity of your question.

You can ask questions about:

• Invoices (sales and purchase)
• Outstanding items and debtors
• Relations (customers and suppliers)
• Bank transactions
• General ledger accounts and trial balance
• VAT returns

See the documentation for example questions.

No. All tools are read-only. No invoices, relations or other data can be created, modified or deleted.

This is a deliberate choice for security. The AI can only read and analyze data.

Always verify! AI can make mistakes. Tips:

• Ask for invoice numbers and references
• Spot-check in Exact Online
• For financial decisions: always verify
• Ask for the source: "Which invoices does this total come from?"

Possible causes:

• No data: The requested period contains no invoices/transactions
• Wrong administration: Specify which administration you mean
• Too broad: Ask more specifically, e.g., "invoices from January" instead of "all invoices"
• Permissions: Your Exact Online user may not have access to certain data

Check your Dashboard for your current usage.

• Free: 200 commands (~60 questions) per month
• Starter: 750 commands (~250 questions) per month
• Pro: 2,500 commands (~800 questions) per month

Your limit resets automatically on the 1st of each month. See also: What are commands?

Yes, we take security very seriously:

• OAuth 2.0: We never see your Exact Online password
• Encryption: Tokens are stored encrypted
• EU hosting: All data stays within the EU (Cloudflare EU)
• Read-only: No write access to your accounting
• No storage: Query results are not stored

Only you (via your API key). We have no access to your accounting data. The MCP server fetches data on your behalf and sends it directly to your AI assistant.

Note: The AI assistant you use (Claude, ChatGPT) processes your data according to their own privacy policy.

Two options:

1. Revoke API key: In your Dashboard, click "Revoke Key"

The requested administration does not exist or you do not have access to it.

• First ask: "Which administrations do I have?"

• Check your permissions in Exact Online

Check:

1. Is the MCP server configured? Check Claude's settings
2. Did you restart Claude Desktop after changing the config?
3. Is your API key correct? Test with a simple question: "Test the Exact Online connection"
4. Check the Cloudflare status for outages
