Frequently asked questions
Where do I find my Quaderno API Key and URL?
Log in to your Quaderno account. Your API URL is simply your domain up top in the browser bar (e.g., https://mycompany.quadernoapp.com). To get the API Key, navigate to Settings > API Keys (or Developers), and copy your private key. Do not share this key as it carries full access. Paste both credentials below.
Can it calculate exact taxes dynamically before a sale?
Yes! Use the calculate_taxes tool and just provide the AI with a country code, postal code, and base amount. Quaderno's world-class engine evaluates real-time location-based tax nuances (VAT, GST) and returns the exact fraction needed.
Can I draft custom test invoices natively in chat?
Absolutely. You can use create_transaction. Instruct your agent to format a JSON array with products and amounts, linking to a specific contact_id. The server submits this array to Quaderno and records the fully realized transaction safely.
Will deleting a contact via the AI remove them permanently?
Yes. The delete_contact operation relies heavily on standard destructive API instructions. Running this means the contact is gone entirely from the Quaderno dashboard. Always review deletion queries cautiously before approving execution.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
